allocate new mapping entries instead of using a default size (512 entries). They also
offer a flexible time-based RPC mapping entry that removes the mapping entry
(auto-clean) without affecting the associated active RPC sessions, including both
control session and data session.
[See RPC ALG Feature Guide for Security Devices.]
Release 12.1X46-D20 Software Features
Chassis Cluster
•
Autorecovery of fabric link [SRX Series]—The fabric link feature supports autorecovery,
which includes the following enhancements:
•
Fabric monitoring feature is enabled by default on high-end SRX Series, and hence
recovery of fabric link and synchronization takes place automatically.
•
If the fabric link goes down, RG1+ becomes ineligible on either the secondary node
or the node with failures, by default. The node remains in this state until the fabric
link comes up or the other node goes away.
•
If the fabric link goes down followed by the control link, then after approximately 66
seconds the secondary node (or the node with failures) assumes that the remote
node is dead and takes over as the primary node.
[See Understanding Chassis Cluster Fabric Links.]
•
Enhanced debugging support for chassis cluster [SRX Series]—The chassis cluster
debugging functionality has the following enhancements:
•
The show chassis cluster status command output includes failure reasons (acronyms
and their expansions) when the redundancy group's priority is zero.
•
Cleaner jsrpd process includes removing unwanted logs and moving the debug log
message from level LOG_INFO to LOG_DEBUG.
•
The show chassis cluster information command output displays redundancy group,
LED, and monitored failure details.
•
SNMP traps send messages when a node's weight goes down and also when it
recovers.
•
The show chassis cluster ip-monitoring command output displays both the global
threshold and the current threshold of each node and displays the weight of each
monitored IP address.
•
A syslog message appears when the control link goes down.
[See show chassis cluster ip-monitoring status.]

New and Changed Features
Public Key Infrastructure (PKI)
•
Online Certificate Status Protocol (OCSP) [SRX Series]—OCSP, like CRL, checks the
revocation status of X509 certificates. Requests are sent to the OCSP server(s)
configured in a CA profile with the ocsp url statement at the [edit security pki ca-profile
profile-name revocation-check] hierarchy level. The use-ocsp option must also be
configured. If there is no response from the OCSP server, the request is then sent to
the location specified in the certificate's AuthorityInfoAccess extension.
[See the “Public Key Infrastructure (PKI)” section in the Junos OS 12.1X46-D20 Feature
Guide.]
Routing Protocols
•
OSPFv3 IPsec authentication and confidentiality [SRX Series]—OSPF for IPv6, also
known as OSPF version 3 (OSPFv3), does not have built-in authentication to ensure
that routing packets are not altered and re-sent to the router. In Junos OS Release
12.1X46-D20, IPsec can be used to secure OSPFv3 interfaces and virtual links and
provide encryption for OSPF packets.
To configure IPsec for OSPF/OSPFv3, define a security association (SA) with the
security-association sa-name configuration option at the [edit security ipsec] hierarchy
level. The configured SA is then applied it to the OSPF/OSPFv3 interface or virtual link
configuration.
[See the “Routing Protocols” section in the Junos OS 12.1X46-D20 Feature Guide.]
Unified Threat Management (UTM)
•
UTM license enforcement [SRX Series]—License enforcement is supported for UTM
features, including Sophos antivirus, enhanced Web filtering, and antispam filtering
on all high-end SRX Series devices in addition to branch SRX Series devices. You can
add or remove UTM licenses on SRX Series devices. Each feature license is tied to
exactly one software feature and is valid for exactly one device.

Release 12.1X46-D15 Software Features
IP Monitoring
Copyright © 2016, Juniper Networks, Inc.
7
Junos OS 12.1X46 Release Notes
•
IP monitoring with interface as next-hop option [Branch SRX Series]—IP monitoring
enables you to configure a static route with a P2P interface as a next-hop action when
IP monitoring has failed.
The following added functions support the track-ip option:
•
Next-hop type checking: IP address or interface.
•
Interface type checking for next-hop. Only a P2P interface is supported; an error
message results when the configuration is committed.
•
You can use the interface as a next-hop to construct route parameters and call RPD
API to add a static route; log route addition results.
•
You can use existing code to delete the route when the primary route recovers.
[See “IP Monitoring” section in Junos OS 12.1X46-D15 Feature Guide.]
Release 12.1X46-D10 Software Features
Application Layer Gateways (ALGs)
•
ALG message buffer optimization—Starting in Junos OS Release 12.1X46-D10, the
ALG message buffer optimization feature has been enhanced to reduce high memory
consumption. This feature is supported on all SRX Series and J Series devices.
A message buffer is allocated only when the packet is ready to process. The buffer is
freed after the packet completes ALG handling, including modifying the payload,
performing NAT, opening a pinhole for a new connection between a client and a server,
and transferring data between a client and a server located on opposite sides of a
Juniper Networks device.
This feature has the following enhancements:
•
Unnecessary objcache buffering is avoided, resulting in low memory utilization.
•
jbuf manipulation is used to simplify the message buffer logic.
•
Full-fledged message buffer support for the ALG line breaker is more flexible.
•
ALG Manager and ALG plug-in logic clarity are optimized.
[See alg-manager.]
•
IPv6 support for SIP ALG—This feature is supported on all SRX Series and J Series
devices.
Starting with Junos OS Release 12.1X46-D10, IPv6 is supported on the SIP ALG along
with NAT-PT mode and NAT64 address translation.
The SIP ALG processes the IPv6 address in the same way it processes the IPv4 address
for updating the payload if NAT is configured and opening pinholes for future traffic.
NAT-PT is implemented by normal NAT from IPv6 address to IPv4 address and vice
versa. The SIP ALG processes those address translations in payload just as the
addresses are processed in normal NAT.
NAT64 is a mechanism to allow IPv6 hosts to communicate with IPv4 servers. NAT64
is required to keep the IPv6 to IPv4 address mapping.
8
Copyright © 2016, Juniper Networks, Inc.
New and Changed Features
Previously, Session Traversal Utilities for NAT (STUN) worked without the SIP ALG.
This means that the SIP ALG was not involved when persistent NAT was configured.
Starting with Junos OS Release 12.1X46-D10, STUN can coexist with the SIP ALG and
SIP ALG is involved when persistent NAT is configured.
[See SIP ALG Feature Guide for Security Devices.]
•
IPv6 support for RTSP ALG—This feature is supported on all SRX Series and J Series
devices.
Real-Time Streaming Protocol (RTSP) is an Application Layer protocol for controlling
the delivery of data with real-time properties. The RTSP ALG accesses existing media
files over the network and controls the replay of the media.
Starting with Junos OS Release 12.1X46-D10, IPv6 is supported on the RTSP ALG along
with NAT-PT mode and NAT64 address translation.
This feature enables the RTSP ALG to parse IPv6 RTSP packets, open an IPv6 pattern
pinhole, and translate the Layer 7 IPv6 address according to the NAT configuration.
Also, support for IPv6 RTSP transaction pass through under permission policy and
IPv6 RTSP transaction pass through under NAT-PT and NAT 64 are enabled.
[See SIP RTSP ALG Feature Guide for Security Devices.]
•
IPv6 support for PPTP ALG—Starting with Junos OS Release 12.X46-D10, this feature
is supported on all SRX Series devices.
PPTP ALG provides an ALG for the Point-to-Point Tunneling Protocol (PPTP). The
PPTP is a Layer 2 protocol that tunnels PPP data across TCP/IP networks. The PPTP
client is freely available on Windows systems and popularly applied on Linux systems;
it is widely deployed for building VPNs.
To support IPv6, the PPTP ALG parses both IPv4 and IPv6 PPTP packets, performs
NAT, and then opens a pinhole for the data tunnel. The flow module supports IPv6 to
parse the GRE packet and use the GRE call ID as fake port information to search the
session table and gate table.
•
Support for SCCP v20—This feature is supported on all SRX Series devices.
Starting in Junos OS Release 12.1X46-D10, the SCCP ALG supports SCCP versions 16,
17, and 20 and several SCCP messages have been updated with a new format. Cisco
Call Manager (CM) version 7 uses SCCP version 20.
[See SCCP ALG Feature Guide for Security Devices.]

Junos OS 12.1X46 Release Notes
AppSecure
•
Application-aware quality of service (AppQoS)—Starting in Junos OS Release
12.1X46-D10, AppQoS is supported on all branch SRX Series devices.
AppQoS provides a mechanism for prioritizing traffic utilizing the results of the
Application Identification Engine. AppQoS provides application-level traffic control
for administrators needing to ensure that business-critical applications get preferential
treatment.
AppQoS enables the network administrator to meter, mark, and honor traffic priority
based on application policies. It provides application-aware DSCP marking by
implementing Layer 7 application-based DSCP rewriters. To apply different loss priority
levels to different traffic groups, Layer 2-based to Layer 4-based honoring has been
expanded to Layer 7. AppQoS accomplishes application-aware rate limiting by setting
the bandwidth limit and burst size limit for different applications.
[See Understanding Application QoS (AppQoS).]
Dynamic Host Configuration Protocol (DHCP)
•
DHCP relay—Starting in Junos OS Release 12.1X46-D10, the existing DHCP relay feature
on all branch SRX Series devices has been enhanced to include chassis cluster support.
[See Understanding DHCP Relay Agent Operation.]
Flow and Processing
•
Enhanced IPv6 support for the screen feature—This feature is supported on all branch
SRX Series and J Series devices.
IPv6 support is extended for the following screen features:
•
IPv6 extension header checking and filtering
•
IPv6 packet header checking and filtering
•
ICMPv6 checking and filtering
New statements and commands allow you to configure these enhancements using
security zones similar to previous screen configurations. You can enable, disable, and
update screens to drop packets, create logs, and provide increased statistics for IPv6
traffic.
NOTE: By default, IPv6 packets bypass the screen feature.
[See Understanding IPv6 Support for Screens.]
•
Enhanced IPv6 support for flow—This feature is supported on all branch SRX Series
and J Series devices.
IPv6 support is extended for checking and filtering IPv6 extension headers (in
accordance with RFC 2460) and IPv6 link-local addresses (in accordance with RFC
4291) in a flow. Nonconforming IPv6 packets will be discarded.
10
Copyright © 2016, Juniper Networks, Inc.
New and Changed Features
•
Enhancements to flow trace options—This feature is supported on all branch SRX
Series and J Series devices.
Starting in Junos OS Release 12.1X46-D10, flow trace granularity has been enhanced
to filter logs effectively. As a result you can access relevant trace messages easily and
avoid large traces that slow down your system. You can set the level of message you
want displayed by using the new trace-level statement at the [edit security flow
traceoptions] hierarchy level. You can use new flags to trace additional operations
such as fragmentation, high availability, multicast, session, tunnel, and route.
[See traceoptions (Security Flow).]
•
Monitoring flow sessions—This feature is supported on all branch SRX Series and J
Series devices.
Beginning with Junos OS Release 12.1X46-D10, you can monitor flow using filters that
match different criteria (such as source and destination addresses). New operational
mode commands monitor security flow filter and monitor security flow file have been
added. These commands allow you to debug without having to commit or modify your
running configuration. Previously, you were required to commit the configuration to
turn on trace options, which could possibly change the state of your device.
[See Monitoring Security Flow Sessions Overview.]
Intrusion Detection and Prevention (IDP)
•
IDP IPv6 inspection—Starting in Junos OS Release 12.1X46-D10, IDP supports IPv6
inspection on the SRX100, SRX210, SRX220, SRX240, SRX550, and SRX650. IPv6
builds upon the functionality of IPv4, providing improvements to addressing,
configuration and maintenance, and security.
This feature supports:
•
IPv6 traffic inspection
•
Attack detection inspection in protocol decoders that support IPv6
•
IDP signature database
•
IDP logging
•
Application identification results
Use the show security flow session idp family command with the inet or inet6 option
to view IPv4 or IPv6 statistics.
[See IDP Monitoring and Troubleshooting Guide for Security Devices.]
•
IDP security packet capture—Starting in Junos OS Release 12.1X46-D10, this feature
is supported on the SRX100, SRX210, SRX220, SRX240, SRX550, and SRX650.
Viewing packets that precede and follow an attack helps you determine the purpose
and extent of an attempted attack, whether an attack was successful, and if any
network damage was caused. Packet analysis also aids in defining attack signatures
to minimize false positives.
Copyright © 2016, Juniper Networks, Inc.
11
Junos OS 12.1X46 Release Notes
Use the show security idp counters packet-log command to display details about the
progress, success, and failure of packet capture activity.
You can specify pre-attack, post-attack, and post-attack timeout values. The pre-attack
and post-attack default values are 1, and the default post-attack timeout value is 5.
NOTE: Support for packet capture is available only once on each session.
[See Understanding Security Packet Capture.]
IP Spoofing
•
IP spoofing in transparent mode—Starting in Junos OS Release 12.1X46-D10, this
feature is supported on all branch SRX Series devices.
The IP spoofing feature has been enhanced to include Layer 2 transparent mode
support. IP spoofing is most frequently used in denial-of-service attacks. In an IP
spoofing attack, the attacker gains access to a restricted area of the network and
inserts a false source address in the packet header to make the packet appear to come
from a trusted source. When SRX Series devices are operating in transparent mode,
the IP spoof-checking mechanism makes use of address book entries.
NOTE:
• IP spoofing in Layer 2 transparent mode does not support DNS and
wildcard addresses.
•
IP spoofing in Layer 2 transparent mode is not supported on IPv6, because
branch SRX Series devices do not support IPv6 in Layer 2 transparent
mode.
[See Understanding IP Spoofing in Layer 2 Transparent Mode.]
J-Web
•
•
12
Management support for NAT options—Starting in Junos OS Release 12.1X46-D10,
support is provided to monitor the following NAT options on all SRX Series devices:
•
Utilization for all source pools
•
Successful, failed, and current sessions for source pools, source rules, destination
rules, and static rules
•
Source addresses and source ports for static rules
•
Source ports for source rules
Support is provided to configure the following NAT options on all SRX Series devices:
•
Source address and port as match criteria for static rules
•
Source port as match criteria for source rules
•
Upper and lower thresholds at which an SNMP trap is triggered for source rules and
pools, destination rules, and static rules
Copyright © 2016, Juniper Networks, Inc.
New and Changed Features
•
User firewall J-Web support
•
Source identity-based firewall policy—Starting in Junos OS Release 12.1X46-D10,
this feature is supported on the existing Firewall Policies Configuration and Monitoring
Policies pages on all branch SRX Series devices. This feature allows you to configure
and monitor source identities in a firewall policy.
•
New J-Web pages for user firewall—Starting in Junos OS Release 12.1X46-D10, new
user firewall pages are supported on all branch SRX Series devices.
The following webpages have been added to the J-Web user interface:
•
•
Authentication Priority Configuration Page—You can either disable an optional
authentication source or reassign a unique priority to it.
•
Local Authentication Configuration Page and Local Authentication Monitoring
Page—You can configure and monitor local Firewall authentication.
•
UAC Settings Configuration Page and UAC Authentication Monitoring Page—You
can configure UAC and monitor UAC authentication.
Allow adding a new policy and moving an existing policy to an arbitrary location
•
Firewall Policies Configuration Page Options—Starting in Junos OS Release
12.1X46-D10, several new options on the Firewall Policies Configuration page are
supported on all branch SRX Series devices. The Add menu includes Add before and
Add after options that allow you to add a new policy before or after a selected policy.
On the Move menu, there is a new Move to option that allows you to specify a target
location. You can also drag and drop a policy to the target location.
•
Checking Policies Monitoring Page—Starting in Junos OS Release 12.1X46-D10, the
Move to option on the Checking Policies Monitoring page is supported on all branch
SRX Series devices.
Management Information Bases (MIBs)
•
SNMP aggregation for policy MIBs—Starting in Junos OS Release 12.1X46-D10, this
feature is supported on all SRX Series devices.
A set of systemwide policy statistics such as policy-allowed packets, bytes and rates,
policy-dropped packets, bytes and rates, policy flows allowed, and rate statistics have
been added in the enterprise-specific policy MIB JUNIPER-JS-POLICY-MIB. You can
obtain the policy statistics by using the SNMP agent or the CLI operational mode
commands. Use the following CLI commands to set, clear, and display the systemwide
policy statistics:
•
set security policies policy-stats system-wide <disable | enable>–Configures
systemwide policy statistics. Disabled by default.
•
clear security policies statistics–Clears the systemwide policy statistics.
•
show snmp mib walk jnxJsPolicySystemStats–Displays both IPv4 and IPv6 statistics.
•
show snmp mib walk jnxJsPolicySystemStatsIPv4–Displays only IPv4 statistics.
Copyright © 2016, Juniper Networks, Inc.

Junos OS 12.1X46 Release Notes
[See Policy Objects MIB.]
Virtual Private Networks (VPNs)
•
Enhanced X2 interface monitoring—This feature is supported on all SRX Series devices.
In an LTE mobile network, X2 interfaces are used to connect Evolved Node Bs (eNodeBs)
for signal handover, monitoring, and radio coverage. SRX Series devices connect these
eNodeBs using IPsec tunnels.
This feature enables you to monitor traffic between eNodeBs by snooping into the
clear text traffic as it flows from one IPsec tunnel to another. Use the monitor-filter
statement at the [edit security forwarding-options] hierarchy level to duplicate clear
text packets and send them to the physical interface. You can then use Ethereal or
other packet analyzers to verify or collect the X2 traffic.
[See Understanding X2 Traffic Monitoring ]
•
Support for IPv6 address encapsulation in route-based one-to-one site-to-site VPN
tunnels—This feature is supported on all SRX Series devices.
In tunnel mode, IPsec encapsulates the original IP datagram—including the original IP
header—within a second IP datagram. The outer IP header contains the IP address of
the gateway, while the inner header contains the ultimate source and destination IP
addresses. The outer and inner IP headers can have a protocol field of IPv4 or IPv6. As
of Junos OS Release 12.1X46-D10, the following tunnel modes are supported on SRX
Series devices:
•
IPv4-in-IPv4 tunnels encapsulate IPv4 packets inside IPv4 packets.
•
IPv6-in-IPv6 tunnels encapsulate IPv6 packets inside IPv6 packets.
•
IPv6-in-IPv4 tunnels encapsulate IPv6 packets inside IPv4 packets.
•
IPv4-in-IPv6 tunnels encapsulate IPv4 packets inside IPv6 packets.
There are no new CLI configuration statements for this feature.
IPv4 and IPv6 traffic can be routed into a single IPv4 or IPv6 tunnel; the st0 interface
bound to the tunnel must be configured for both family inet and family inet6. Dual
stack tunnels—parallel IPv4 and IPv6 tunnels over a single physical external interface
to different VPN peers—are also supported.
[See VPN Feature Support for IPv6 Addresses.]
•
Dead peer detection (DPD) enhancements—This feature is supported on all SRX
Series devices.
Network devices use the DPD protocol to verify the existence and availability of other
peer devices. The default DPD mode optimized sends probes if there is no incoming
IKE or IPsec traffic from the peer within a configured interval after outgoing packets
are sent to the peer. The always-send option sends DPD probes at configured intervals
regardless of traffic activity between peers. A new configuration option probe-idle-tunnel
at the [edit security ike gateway dead-peer-detection] hierarchy level sends DPD probes
when there is no incoming or outgoing IKE or IPsec traffic between peers.
14
Copyright © 2016, Juniper Networks, Inc.
New and Changed Features
NOTE: We recommend that you configure probe-idle-tunnel instead of
always-send.
For all DPD modes, Phase 1 and Phase 2 security associations are cleared if a specified
number of probes are sent with no response from the peer.
[See Understanding Dead Peer Detection.]
•
Multiple traffic selectors on a route-based VPN—This feature is supported on all
branch SRX Series devices.
A traffic selector (also known as a proxy ID in IKEv1) is an agreement between IKE peers
to permit traffic through a tunnel if the traffic matches a specified pair of local and
remote addresses. With this feature, you can define multiple traffic selectors within a
specific route-based VPN, resulting in a unique SA for each traffic selector configured.
Only traffic that conforms to a traffic selector is permitted through the associated
IPsec SA.
To configure a traffic selector, use the traffic-selector configuration statement at the
[edit security ipsec vpn vpn-name] hierarchy level. The traffic selector pair is defined
with the mandatory local-ip ip-address and remote-ip ip-address statements. The CLI
operational command show security ipsec security-association traffic-selector
traffic-selector displays SA information for the specified traffic selector.
[See Understanding Traffic Selectors in Route-Based VPNs.]
•
IKEv2 configuration payload support with RADIUS—This feature is supported on all
SRX Series devices.
Configuration payload is an Internet Key Exchange (IKE) version 2 feature used to
propagate provisioning information from an IKE responder to the IKE initiator. Starting
with Junos OS Release 12.1X46-D10, IKEv2 configuration payload is supported with
route-based VPNs only. The following attribute types, defined in RFC 5996, Internet
Key Exchange Protocol Version 2 (IKEv2), can be returned to the IKE initiator by the IKE
responder:
•
INTERNAL_IP4_ADDRESS
•
INTERNAL_IP4_NETMASK
•
INTERNAL_IP4_DNS
For the IKE responder to provide the initiator with provisioning information, it must
acquire the information from a specified source such as a RADIUS server. Provisioning
information can also be returned from a DHCP server through a RADIUS server. On the
RADIUS server, the user information should not include an authentication password.
As in previous Junos OS releases for the SRX Series, the RADIUS server profile is bound
to the IKE gateway using the xauth access-profile profile-name configuration at the
[edit security ike gateway gateway-name] hierarchy level.
This feature is supported only for point-to-multipoint secure tunnel (st0) interfaces.
For point-to-multipoint interfaces, the interfaces must be numbered and the addresses
Copyright © 2016, Juniper Networks, Inc.
15
Junos OS 12.1X46 Release Notes
in the configuration payload INTERNAL_IP4_ADDRESS attribute type must be within
the subnetwork range of the associated point-to-multipoint interface.
NOTE: IKEv2 on SRX Series devices does not support policy-based VPNs
or VPN monitoring.
[See Understanding Internet Key Exchange Version 2.]
•
IKEv2 with NAT-T and dynamic endpoint VPN—This feature is supported on all SRX
Series devices.
Starting with Junos OS 12.1X46-D10, both IKEv2 initiators and responders in a
route-based VPN can be behind NAT devices. The IKEv2 NAT-T feature supports IPsec
traffic that crosses NAT devices. Static NAT and dynamic NAT are supported. In static
NAT, there is a one-to-one relationship between the private and the public addresses.
In dynamic NAT, there is a many-to-one or many-to-many relationship between the
private and public addresses.
Dynamic endpoint (DEP) VPN is a Junos OS feature that covers IKEv2 initiator and
responder perspectives. From the initiator’s perspective, DEP VPN covers the situation
where the IKE external interface address is not fixed and is therefore not known by the
responder. This situation can occur when the peer’s address is dynamically assigned
by an ISP or when the peer’s connection crosses a NAT device that allocates addresses
from a dynamic address pool. From the responder’s perspective, DEP VPN describes
either a finite number of VPNs that are created for a number of VPN peers in a
many-to-many scenario or a shared VPN in a many-to-one scenario.
Starting with Junos OS 12.1X46-D10, the default value for the nat-keepalive option
configured at the [edit security ike gateway gateway-name] hierarchy level has been
changed from 5 seconds to 20 seconds.
[See Understanding NAT-T.]
Web Authentication
•
Web-redirect firewall authentication—Starting in Junos OS Release 12.1X46-D10, Web
authentication redirect enhancement is provided on all SRX Series devices.
With this feature, when you attempt to initiate a connection across the firewall, after
successful authentication the browser launches your original destination URL without
you needing to retype the URL.
The following message is displayed:
Redirecting to the original url, please wait

Changes in Behavior and Syntax
The following current system behavior, configuration statement usage, and operational
mode command usage might not yet be documented in the Junos OS documentation:
Application Firewall
•
Prior to Junos OS Release 12.1X46-D10, when a rule specifies dynamic-application
junos:HTTP without specifying any other nested application, the rule matches all HTTP
traffic whether the traffic contains a nested application or not.
In Junos OS Release 12.1X46-D15 and later, that functionality has changed. When a
rule specifies dynamic-application junos:HTTP, only HTTP traffic with no nested
members is matched.
Consider the following application firewall ruleset:
rule-sets http-ruleset {
rule rule1 {
match {
dynamic-application [junos:HTTP];
}
then {
deny;
}
}
default-rule {
permit;
}
}
Prior to Junos OS Release 11.4R6, the sample rules would be applied to traffic as shown
in the following list:
•
HTTP traffic with or without nested applications would be denied by rule1.
HTTP traffic with a nested application, such as junos:FACEBOOK or junos:TWITTER,
would be denied by rule1.
•
All other traffic would be permitted by the default rule.
In Junos OS Release 11.4R6 and later, the dynamic application junos:HTTP matches
only the HTTP traffic that contains no recognizable nested application. The sample
rules would now be applied differently:
•
Only the HTTP traffic with no nested application would be denied by rule1.
HTTP traffic with a nested application, such as junos:FACEBOOK or junos:TWITTER,
would no longer match rule1.
•
All other traffic would be permitted by the default rule.
Copyright © 2016, Juniper Networks, Inc.
17
Junos OS 12.1X46 Release Notes
HTTP traffic with a nested application, such as junos:FACEBOOK or junos:TWITTER,
would be permitted by the default rule.
•
In Junos OS Release 12.1X46-D10 and earlier, if a nested application is not configured
in any rule, then the nested application would match the default rule and take action
specified in the default rule.
Starting in Junos OS Release 12.1X46-D10, the functionality has changed. If a nested
application matches the default rule, then the application firewall uses the application
type to match the rule and takes action specified in the rule. Use the set security
application-firewall nested-application dynamic-lookup enable command to control
the behavior of the nested application, so that both the application and the nested
application are consistent.
The default behavior of nested application before Junos OS Release 12.1X46-D10:
•
Application firewall matches with the specific rule, if the nested application is
configured explicitly in a rule.
•
Application firewall matches with the default rule, if the nested application is not
configured explicitly in a rule.
•
Records the statistics of the application firewall in the matched rule.
The new behavior of nested application in Junos OS Release 12.1X46-D10:
•
Application firewall matches with an application rule during application firewall
policy lookup, if there is no explicit rule for the nested application.
•
Application firewall matches with a specific rule, if the nested application is configured
explicitly in a rule.
•
Records the statistics of the application firewall in the matched rule.
Chassis Cluster
•
Starting from Junos OS Release 12.1X46-D40, for all branch SRX Series devices, reth
interface supports proxy ARP.
Command-Line Interface (CLI)
New or Changed CLI
•
Starting in Junos OS Release 12.1X46-D30, for all branch SRX Series devices there is
an option to remove the peer loop check for private AS numbers. The no-peer-loop-check
option has been added under the remove-privatecommand at the following hierarchy
levels:

Starting in Junos OS Release 12.1X46-D20, for all branch SRX Series devices in chassis
cluster mode, there is a node option available for all show chassis CLI commands. The

Changes in Behavior and Syntax
node option displays status information for all FPCs or for the specified FPC on a specific
node (device) in the cluster.
•
Prior to Junos OS Release 12.1X46-D10, when you configured the DNS proxy server
using the set system services dns dns-proxy view view-name domain domain-name
forwarder CLI statement, if the IP address specified in the forwarder option was not
available, the DNS query was forwarded to the default DNS servers (DNS servers
provided by the ISP). The device acquired the public IP addresses from the default
DNS servers.
Starting in Junos OS Release 12.1X46-D10, the forward-only option is added to the set
system services dns dns-proxy view view-name domain domain-name forward-only CLI
statement.
You can use the forward-only option to prevent the device from acquiring the public
IP addresses from the DNS servers (by terminating the DNS query) in cases when the
specified IP address is unreachable.

•
On all branch SRX Series and J Series devices, the following commands are now
supported:
CLI Command
Description
show pppoe interfaces
List all PPPoE sessions.
request pppoe connect
Connect to all sessions that are down.
request pppoe connect pppoe interface name
Connect only to the specified session.
request pppoe disconnect
Disconnect all sessions that are up.
request pppoe disconnect session id or pppoe
interface name
Disconnect only the specified session, identified
by either a session ID or a PPPoE interface name.
On all J Series devices, a new CLI request system (halt | power-off | reboot) power-off
fpc command has been introduced to bring Flexible PIC Concentrators (FPCs) offline
before Routing Engines are shut down. This command prevents the short network
outage because of the Layer 2 loop.
CLI Command
Description
request system halt power-off fpc
Bring FPC offline and then halt the system.
request system power-off power-off fpc
Bring FPC offline and then power off the system.
request system reboot power-off fpc
Bring FPC offline and then reboot the system.

Deprecated Items for Security Hierarchy
•
Table 2 on page 20 lists deprecated items (such as CLI statements, commands, options,
and interfaces).
CLI statements and commands are deprecated—rather than immediately removed—to
provide backward compatibility and a chance to bring your configuration into
compliance with the new configuration. We strongly recommend that you phase out
deprecated items and replace them with supported alternatives.

Compatibility
•
Version compatibility for Junos SDK—Beginning with Junos OS Release 12.1X44-D10,
Junos OS applications will install on the Junos OS only if the application is built with
the same release as the Junos OS release on which the application is being installed.
For example, an application built with Junos OS Release 12.1R2 will only install on Junos
OS Release 12.1R2 and will not install on Junos OS Release 12.1R1 or Junos OS Release
12.1R3.
Flow and Processing
•
The minimum value you can configure for TCP session initialization is 4 seconds. The
default value is 20 seconds; if required you can set the TCP session initialization value
to less than 20 seconds.
•
On all branch SRX Series devices, the default value of type of service (ToS) for IKE
packets has been changed from 0x00 to 0xc0.
•
On all branch SRX Series and J Series devices, you can configure the TCP session
timeout in a half-closed state by using the apply-to-half-close-state statement at the
[edit security flow tcp-session time-wait-state] hierarchy level. This enables the system
to apply the configured session timeout on receiving only one FIN packet (either
client-to-server or server-to-client). When this statement is not configured, the default
behavior takes effect, which is to apply the configured session timeout on receiving
both the FIN packets. The default TCP session timeout remains 150 seconds. [See
apply-to-half-close-state.]
Hardware
•
On SRX550 devices, the mini-USB console cable provides a “break” message to the
Windows application whenever the console cable is unplugged and re-plugged. If you
have configured “debugger-on-break”, the system goes to the db> prompt because
the system receives a break character. This behavior is specific to the mini-USB console.
•
Starting in Junos OS Release 12.1X46-D15, external clocking is enabled on SRX550
devices with a DS3/E3 interface. In Junos OS Release 12.1X46-D10 and earlier, the
external clocking option was disabled to overcome the limitations present in the
hardware to support this clocking option.
Interfaces and Routing
•
A new attribute, max-synacks-queued, is added to IDP sensor configuration TCP
reassembler. This attribute defines the maximum syn/ack queued with different SEQ
numbers and takes the values 0 through 5. Also, a new counter, Duplicate Syn/Ack
with different SEQ, is added to the IDP TCP reassembler. This counter displays the
number of syn/ack packets with different SEQ numbers.
•
On SRX240 and SRX650 devices, for the Layer 2 LAG interface, the hash algorithm for
load balancing is now based on source IP address and destination IP address instead
of source MAC address and destination MAC address.

Junos OS 12.1X46 Release Notes
Intrusion Detection and Prevention (IDP)
•
In Junos OS releases earlier than Junos OS Release 12.1X46-D25, TACACS+ options
for authentication and accounting did not include an option for configuring a timestamp
and time zone.
In Junos OS Release 12.1X46-D25 and later releases, you can use the
timestamp-and-timezone option at the [edit system tacplus-options] hierarchy to
include start time, stop time, and time zone attributes in start/stop accounting records.
[See tacplus-options.]
•
A system log message is generated when an IDP signature database update or policy
compilation fails with an empty dynamic group. The system-generated log message
is Dynamic Attack group [dyn_group_1] has no matching members found. Group is empty.
•
By default, values for IDP reassembler packet memory and application identification
packet memory used by IDP are established as percentages of all memory. In most
cases, these default values are adequate.
•
If a deployment exhibits an excessive number of dropped TCP packets or
retransmissions resulting in high IDP reassembly memory usage, use the following
option:
The max-packet-mem-ratio option to reset the percentage of available IDP memory
for IDP reassembly packet memory. Acceptable values are between 5 and 40 percent.
set security idp sensor-configuration re-assembler max-packet-mem-ratio
percentage-value
NOTE: The max-packet-mem option has been deprecated and replaced
by the new max-packet-mem-ratio option.
•
If a deployment exhibits an excessive number of ignored IDP sessions due to
reassembler and application identification memory allocation failures, use the
following options:
•
The max-packet-memory-ratio option sets application identification packet memory
limit as a percentage of available IDP memory. This memory is only used by IDP
in cases where application identification delays identifying an application.
Acceptable values are between 5 and 40 percent.
set security idp sensor-configuration application-identification
max-packet-memory-ratio percentage-value
•
The max-reass-packet-memory-ratio option sets the reassembly packet memory
limit for application identification as a percentage of available IDP memory.
Acceptable values are between 5 and 40 percent.
set security idp sensor-configuration application-identification
max-reass-packet-memory-ratio percentage-value

Copyright © 2016, Juniper Networks, Inc.
Changes in Behavior and Syntax
NOTE: The max-packet-memory option has been deprecated and
replaced by the new max-packet-memory-ratio and
max-reass-packet-memory-ratio options.
•
On all branch SRX Series devices with a single session, when IDP is activated, the
upload and download speeds are slow when compared to the firewall performance
numbers.
To overcome this issue, a new CLI command, set security idp sensor-configuration ips
session-pkt-depth, is introduced, for which the session-pkt-depth sensor-configuration
value is global for any session.
The session-pkt-depth sensor-configuration value specifies the number of packets per
session that are inspected by IDP. Any packets beyond the specified value are not
inspected. For example, when session-pkt-depth sensor-configuration is configured as
“n”, the IDP inspection happens only for first (n-1) packets in that session. Packets from
the nth packet onwards are ignored by IDP.
The default value of session-pkt-depth sensor-configuration is zero. When the default
value of zero is used, the session-pkt-depth value is not addressed, and IDP performs
a full inspection of the session.
•
Starting in Junos OS Release 12.1X46-D25, the show security idp counters flow command
output is changed to include new fields.
Table 3 on page 23 lists the output fields for the show security idp counters flow
command. Output fields are listed in the approximate order in which they appear.

Junos OS 12.1X46 Release Notes
Logical Systems
•
In Junos OS releases earlier than Junos OS Release 12.1X46-D10, when a logical tunnel
interface with an IPv4 address and an Ethernet encapsulation type is configured, a
configuration check is performed to ensure that the address is not identical to its peer
logical tunnel interface address and that both addresses are on the same subnet.
However, when a logical tunnel interface with an IPv6 address and an Ethernet
encapsulation type is configured, no such configuration check is performed.
Starting in Junos OS Release 12.1X46-D10, a check is performed for IPv6 configurations.
However, this change can cause existing IPv6 configurations to fail.
Network Time Protocol
•
When the NTP client or server is enabled in the edit system ntp hierarchy, the
REQ_MON_GETLIST and REQ_MON_GETLIST_1 control messages supported by the
monlist feature within the NTP might allow remote attackers, causing a denial of
service. To identify the attack, apply a firewall filter and configure the router's loopback
address to allow only trusted addresses and networks.
Policy Applications
•
In Junos OS releases earlier than Junos OS Release 12.1X46-D15, when you set the count
option on a security policy using the CLI statement security policies from-zone zone-name
to-zone zone-name policy policy-name then, the count is based on the number of packets
and bytes of all network traffic that the policy allows to pass through the device.
In Junos OS Release 12.1X46-D15 and later, when you set the count option, the count
is based on the number of packets and bytes of all network traffic the policy allows to
pass through the device in both directions: the originating traffic from the client to the
server (from the from-zone to the to-zone), and the return traffic from the server to
the originating client.
Simple Network Management Protocol (SNMP)
•
On all branch SRX Series and J Series devices, the screen SNMP trap
jnxJsScreenCfgChange will not be sent during reboot.
System Logs
On all branch SRX Series devices, the following system log messages have been updated
to include the certificate ID:
•
PKID_PV_KEYPAIR_DEL
Existing message: Key-Pair deletion failed
New message: Key-Pair deletion failed for <cert-id>
•
PKID_PV_CERT_DEL

System Management
•
During a load override, to enhance the memory for the commit script, make sure you
load the configuration by applying the following commands before commit:
set system scripts commit max-datasize 800000000
set system scripts op max-datasize 800000000
User Interface and Configuration
•
You can configure only one rewrite rule for one logical interface. When you configure
multiple rewrite rules for one logical interface, an error message is displayed and the
commit fails.
Virtual Private Networks (VPNs)
•
In previous Junos OS releases, the Pulse client could be automatically downloaded
and installed when users logged into a branch SRX Series device that was configured
for dynamic VPN. Starting with Junos OS Release 12.1X46-D30, Pulse client software
is no longer available from dynamic VPN SRX Series devices and must be obtained
from the Juniper Networks Download Software site at
http://www.juniper.net/support/downloads/
•
On all branch SRX Series devices, for path MTU calculations, the IPsec authentication
data length is fixed at 16 bytes. However, the authentication data length for packets
going through the IPsec tunnel is in accordance with the authentication algorithm
negotiated for that tunnel.
The authentication data lengths for the different algorithms are:
•
•
hmac-md5-96 (12 bytes)
•
hmac-sha-256-128 (16 bytes)
•
hmac-sha1-96 (12 bytes)
For each VPN tunnel, both ESP and AH tunnel sessions are installed on SPUs and the
control plane. In previous Junos OS releases, two tunnel sessions of the same protocol
(ESP or AH) were installed for each VPN tunnel. For branch SRX Series devices, tunnel
sessions are updated with the negotiated protocol after negotiation is completed. For
high-end SRX Series devices, tunnel sessions on anchor SPUs are updated with the
negotiated protocol while non-anchor SPUs retain ESP and AH tunnel sessions.
Copyright © 2016, Juniper Networks, Inc.
31
Junos OS 12.1X46 Release Notes
The ESP and AH tunnel sessions are displayed in the outputs for the show security flow
session and show security flow cp-session operational mode commands.
•
As of Junos OS Release 11.4, checks are performed to validate the IKE ID received from
the VPN peer device. By default, SRX Series and J Series devices validate the IKE ID
received from the peer with the IP address configured for the IKE gateway. In certain
network setups, the IKE ID received from the peer (which can be an IPv4 or IPv6 address,
fully qualified domain name, distinguished name, or e-mail address) does not match
the IKE gateway configured on the SRX Series or J Series device. This can lead to a
Phase 1 validation failure.
To modify the configuration of the SRX Series or J Series device or the peer device for
the IKE ID that is used:
1.
On the SRX Series or J Series device, configure the remote-identity statement at the
[edit security ike gateway gateway-name] hierarchy level to match the IKE ID that is
received from the peer. Values can be an IPv4 or IPv6 address, fully qualified domain
name, distinguished name, or e-mail address.
NOTE: If you do not configure remote-identity, the device uses the IPv4
or IPv6 address that corresponds to the remote peer by default.
2. On the peer device, ensure that the IKE ID is the same as the remote-identity
configured on the SRX Series or J Series device. If the peer device is an SRX Series
or J Series device, configure the local-identity statement at the [edit security ike
gateway gateway-name] hierarchy level. Values can be an IPv4 or IPv6 address, fully
qualified domain name, distinguished name, or e-mail address.
•
The subject fields of a digital certificate can include Domain Component (DC), Common
Name (CN), Organization Unit (OU), Organization (O), Location (L), State (ST), and
Country (C).
In earlier releases, the show security pki ca-certificate and show security pki
local-certificate CLI operational commands displayed only a single entry for each
subject field, even if the certificate contained multiple entries for a field. For example,
a certificate with two OU fields such as “OU=Shipping Department, OU=Priority Mail”
displayed with only the first entry “OU=Shipping Department.” The show security pki
ca-certificate and show security pki local-certificate CLI commands now display the
entire contents of the subject field, including multiple field entries.
The commands also display a new subject string output field that shows the contents
of the subject field as it appears in the certificate.

Known Behavior
Application Layer Gateways (ALGs)
•
On all SRX Series devices, you can define the Sun RPC and MS-RPC mapping entry
ageout value using the set security alg sunrpc map-entry-timeout value and set security
alg msrpc map-entry-timeout value commands. The ageout value ranges from 8 hours
to 72 hours, and the default value is 32 hours.
If either the Sun RPC ALG or the MS-RPC ALG service does not trigger the control
negotiation even after 72 hours, the maximum RPC ALG mapping entry value times
out and the new data connection to the service fails.
•
The maximum size of the jbuf is 9 Kb. If the message buffer size is more than 9 Kb, the
entire message cannot be transferred to the ALG packet handler. This causes
subsequent packets in the session to bypass ALG handling, resulting in a transaction
failure.
The limitations for SCCP ALGs are as follows:
•
The SCCP is a Cisco proprietary protocol. So, any changes to the protocol by Cisco
cause the SCCP ALG implementation to break. However, workarounds are provided
to bypass strict decoding and allow any protocol changes to be handled gracefully.
•
The SCCP ALG validates protocol data units (PDUs) with message IDs in the ranges
[0x0 - 0x12], [0x20 - 0x49], and [0x81 - 0x14A]. By default, all other message IDs are
treated as unknown messages and are dropped by the SCCP ALG.
•
Any changes to the policies will drop the sessions and impact already established
SCCP calls.
•
The SCCP ALG opens pinholes that are collapsed during traffic or media inactivity. This
means that during a temporary loss of connectivity, media sessions are not
reestablished.
•
CallManager (CM) version 6.x and later does not support TCP probe packets in chassis
cluster mode. As a result, the existing SCCP sessions will break when there is a failover.
You can still create new SCCP sessions during failover.

Junos OS 12.1X46 Release Notes
The PPTP ALG with IPv6 support has the following limitation:
•
Because PPP packets are compressed with Microsoft Point-to-Point Encryption (MPPE)
protocol after the tunnel is set up, translation of the IP header in the PPP package
cannot be handled; therefore, to make sure PPTP connection works well, the PPTP
client must be able to work in dual stack mode. So that an IPv6 PPTP client can accept
an IPv4 address for PPP tunnel interface, by which it can communicate with the IPv4
PPTP server without IP address translation for PPP packets.
The RTSP ALG with IPv6 support has the following limitations:
•
Real-Time Streaming Protocol (RTSP) is an Application Layer protocol for controlling
the delivery of data with real-time properties. The RTSP ALG supports a peer client,
and the server transmits real-time media; it does not support third-party endpoints
involved in the transaction.
•
In case of destination NAT or NAT64 for IP address translation, if the RTSP message
(including the Session Description Protocol (SDP) application content) length exceeds
2500 bytes, then the RTSP ALG processes only the first 2500 bytes of the message
and ignores the rest of the message. In this scenario, the IP address in the RTSP message
is not translated if the IP address does not appear in the first 2500 bytes.
The SIP ALG with IPv6 support has the following limitation:
•
When NAT64 with persistent NAT is implemented, the SIP ALG adds the NAT translation
to the persistent NAT binding table if NAT is configured on the Address of Record
(AOR). Because persistent NAT cannot duplicate the address configured, coexistence
of NAT66 and NAT64 configured on the same address is not supported.
Only one binding is created for the same source IP address.
AppSecure
•
J-Web pages for AppSecure are preliminary.
•
Custom application signatures and custom nested application signatures are not
currently supported by J-Web.
•
When ALG is enabled, application identification includes the ALG result to identify the
application of the control sessions. Application firewall permits ALG data sessions
whenever control sessions are permitted. If the control session is denied, there will be
no data sessions. When ALG is disabled, application identification relies on its signatures
to identify the application of the control and data sessions. If a signature match is not
found, the application is considered unknown. Application firewall handles applications
based on the application identification result.
AX411 Access Points
34
•
On SRX210, SRX240, and SRX650 devices, you can configure and manage a maximum
of four access points.
•
On all branch SRX Series devices, managing AX411 WLAN Access Points through a
Layer 3 ae interface is not supported.

Chassis Cluster
•
SRX100, SRX210, SRX240, and SRX650 devices have the following chassis cluster
limitations:
•
VRRP is not supported.
•
Unified ISSU is not supported.
•
The 3G dialer interface is not supported.
•
On SRX Series device failover, access points on the Layer 2 switch reboot and all
wireless clients lose connectivity for 4 to 6 minutes.
•
VDSL Mini-PIMs are not supported in chassis cluster.
•
Queuing on the ae interface is not supported.
•
Group VPN is not supported.
•
On SRX100 and SRX110 devices, switching is not supported in chassis cluster mode.

On the lsq-0/0/0 interface, Link services MLPPP, MLFR, and CRTP are not supported.
•
On the lt-0/0/0 interface, CoS for RPM is not supported.
Starting with Junos OS Release 12.1X45-D10 and later, sampling features such as flow
monitoring, packet capture, and port mirroring are supported on reth interfaces.
•
On all SRX Series devices in a chassis cluster, flow monitoring for version 5 and
version 8 is supported. However, flow monitoring for version 9 is not supported.
•
If you use packet capture on reth interfaces, two files are created, one for ingress
packets and the other for egress packets based on the reth interface name. These
files can be merged outside of the device using tools such as Wireshark or Mergecap.
•
If you use port mirroring on reth interfaces, the reth interface cannot be configured
as the output interface. You must use a physical interface as the output interface.
If you configure the reth interface as an output interface using the set
forwarding-options port-mirroring family inet output command, the following error
message is displayed.
Port-mirroring configuration error.
Interface type in reth1.0 is not valid for port-mirroring or next-hop-group config
•
Packet-based forwarding for MPLS and ISO protocol families is not supported.
•
The factory default configuration for SRX100 devices automatically enables Layer 2
Ethernet switching. Layer 2 Ethernet switching is not supported in chassis cluster mode
for SRX100 devices. If you use the factory default configuration, you must delete
Ethernet switching before you enable chassis clustering.
•
On all J Series devices, a Fast Ethernet port from a 4-port Ethernet PIM cannot be used
as a fabric link port in a chassis cluster.

Junos OS 12.1X46 Release Notes
•
On all branch SRX Series devices, reth interfaces and the lo0 interface are supported
for IKE external interface configuration in IPsec VPN. Other interface types can be
configured, but IPsec VPN might not work.
•
On all J Series devices, the ISDN feature on chassis cluster is not supported.
Command-Line Interface (CLI)
•
On all branch SRX Series and J Series devices, the clear services flow command is not
supported.
•
On all J Series devices, RADIUS accounting is not supported.
•
On SRX210 and SRX240 devices, J-Web crashes if more than nine users log in to the
device by using the CLI. The number of users allowed to access the device is limited
as follows:
•
For SRX210 devices: four CLI users and three J-Web users
•
For SRX240 devices: six CLI users and five J-Web users
•
On J6350 devices, there is a difference in the power ratings provided by user
documentation (J Series Services Routers Hardware Guide and PIM, uPIM, and ePIM
Power and Thermal Calculator) and the power ratings displayed by CLI (by a unit of
1). The CLI display rounds off the value to a lower integer, and the ratings provided in
user documentation round off the value to the higher integer. As a workaround, follow
the user documentation for accurate ratings.
•
On all branch SRX Series devices, the tunnel-queuing option is not supported in chassis
cluster mode.
Connectivity Fault Management (CFM)
•
•
CFM is not supported on the following interfaces:
•
8-Port Gigabit Ethernet SFP XPIM
•
2-Port 10-Gigabit Ethernet XPIM
•
1-Port SFP Mini-PIM
CFM is supported only on interfaces with the Ethernet switching family.
Dynamic Host Configuration Protocol (DHCP)
36
•
On all branch SRX Series devices, DHCP relay is unable to update the binding status
based on DHCP_RENEW and DHCP_RELEASE messages.
•
On all branch SRX Series and J Series devices, DHCPv6 client authentication is not
supported.
•
On all branch SRX Series and J Series devices, DHCP client and server functionality is
not supported in a chassis cluster.
•
On all branch SRX Series devices, DHCPv6 client does not support:

•
Temporary addresses
•
Reconfigure messages
•
Multiple identity association for nontemporary addresses (IA_NA)
•
Multiple prefixes in a single identity association for prefix delegation (IA_PD)
•
Multiple prefixes in a single router advertisement
Flow and Processing
•
On all branch SRX Series devices, GRE fragmentation is not supported in packet-based
mode.
•
On all branch SRX Series and J Series devices, a mismatch between the Firewall Counter
Packet and Byte Statistics values, and between the Interface Packet and Byte Statistics
values, might occur when the rate of traffic increases above certain rates of traffic.
•
On SRX100, SRX210, SRX220, SRX240, and SRX650 devices, due to a limit on the
number of large packet buffers, Routing Engine based sampling might run out of buffers
for packet sizes greater than or equal to 1500 bytes and hence those packets will not
be sampled. The Routing Engine could run out of buffers when the rate of the traffic
stream is high.
•
On SRX100 and SRX240 devices, the data file transfer rate for more than 20 Mbps is
reduced by 60 percent with the introduction of Junos Pulse 1.0 client as compared to
the Acadia client that was used before Junos OS Release 11.1.
•
On SRX100, SRX210, SRX220, SRX240, and SRX650 devices, the default authentication
table capacity is 10,000; the administrator can increase the capacity to a maximum
of 15,000.
•
On all branch SRX Series and J Series devices, when devices are operating in flow mode,
the Routing Engine side cannot detect the path MTU of an IPv6 multicast address
(with a large size packet).
•
On all branch SRX Series devices, you cannot configure route policies and route patterns
in the same dial plan.
•
On all J Series devices, even when forwarding options are set to drop packets for the
ISO protocol family, the device forms ES-IS adjacencies and transmits packets because
ES-IS packets are Layer 2 terminating packets.
•
On all branch SRX Series and J Series devices, high CPU utilization triggered for reasons
such as CPU intensive commands and SNMP walks causes the BFD protocol to flap
while processing large BGP updates.
•
On SRX210, SRX240, and J Series devices, broadcast TFTP is not supported when flow
is enabled on the device.

On SRX100 devices, Layer 3 control protocols (OSPF, using multicast destination MAC
address) on the VLAN Layer 3 interface work only with access switch ports.
Hardware
•
On all branch SRX Series devices, a chassis cluster is only supported when both devices
are the same model and have the same amount of memory. Thus, a chassis cluster is
not supported if it combines SRX Series branch devices with 1-GB and 2-GB memory
in the same cluster.
Interfaces and Routing
•
When using SRX Series devices in chassis cluster mode, we recommend that you do
not configure any local interfaces (or combination of local interfaces) along with
redundant Ethernet interfaces.
For example:
The following configuration of chassis cluster redundant Ethernet interfaces, in which
interfaces are configured as local interfaces, is not recommended:
ge-2/0/2 {
unit 0 {
family inet {
address 1.1.1.1/24;
}
}
}

reth2 {
redundant-ether-options {
redundancy-group 1;
}
unit 0 {
family inet {
address 1.1.1.1/24;
}
}
}
}
•
On SRX100, SRX110, SRX210, and SRX220 devices, you cannot configure the same
VRRP group ID on different interfaces of a single device.
•
On all branch SRX Series devices, PIM does not support upstream and downstream
interfaces across different virtual routers in flow mode
•
On all branch SRX Series devices, the Link Layer Discovery Protocol (LLDP) is not
supported on reth interfaces.
•
On all J Series devices, the flow monitoring version 9 has the following limitations:
•
•
Routing Engine based flow monitoring V5 or V8 mode is mutually exclusive with
inline flow monitoring V9.
•
Flow aggregation for V9 export is not supported.
•
Only UDP over IPv4 or IPv6 protocol can be used as the transport protocol.
•
Only the standard IPv4 or IPv6 template is supported for exporting flow monitoring
records.
•
User-defined or special templates are not supported for exporting flow monitoring
records.
On all branch SRX Series and J Series devices, flow monitoring IPv6 version 9 has the
following limitations:
•
MPLS in not supported.
•
User-defined version 9 templates are not supported.
•
Routing Engine based flow monitoring version 9 is not supported.
•
Flow monitoring and accounting are not supported in chassis cluster mode.
•
Flow monitoring and accounting are not supported on an ae interface.
•
J-Web for IPv6 sampled packets is not supported.

Junos OS 12.1X46 Release Notes
•
SNMP queries for IPv6 sampled packets are not supported
•
Flow monitoring can be configured in version 5, version 8, or version 9 export mode.
Up to eight version 9 collectors are supported in export mode.
•
Scope of accounting of IPv6 flow monitoring version 9 packets associated with
pseudointerfaces (such as IRB, ML, LAG, VLAN, and GRE) is not supported.
•
Creation of an SCTP session (parallel to TCP) between an exporter and a collector
for gathering flow monitoring information is not supported.
•
Maximum flow sessions that might be supported include:
•
40
•
A device with 1-GB RAM, such as an SRX220 device, might support up to 15,000
flow monitoring sessions at a time.
•
A device with 2-GB RAM, such as an SRX650 device, might support up to 59,900
flow monitoring sessions at a time.
Changes in source AS and destination AS are not immediately reflected in exported
flows.
•
On all branch SRX Series devices, IPv6 traffic transiting over IPv4 based IP over IP
tunnel (for example, IPv6-over-IPv4 using ip-x/x/x interface) is not supported.
•
The ATM interface takes more than 5 minutes to come up when CPE is configured in
ANSI-DMT mode and CO is configured in automode. This occurs only with ALU 7300
DSLAM, due to limitation in current firmware version running on the ADSL Mini-PIM.
•
On SRX100 and J Series devices, dynamic VLAN assignments and guest VLANs are
not supported.
•
On all branch SRX Series devices, the subnet directed broadcast feature is not
supported.
•
On SRX650 devices, Ethernet switching is not supported on Gigabit Ethernet interfaces
(ge-0/0/0 through ge-0/0/3 ports).
•
On SRX210, SRX220, SRX240, and SRX650 devices, when using stream mode security
logging, security logs cannot be sent to NSM or another syslog server if the server is in
the same subnet as interface fxp0. Stream mode syslog can only be routed out via
revenue ports and not via the fxp0 interface. This implies that you cannot configure
the security log server in the same subnet as the fxp0 interface.
•
On all branch SRX Series devices, the number of child interfaces per node is restricted
to 4 on the reth interface and the number of child interfaces per reth interface is
restricted to 8.
•
On SRX240 High Memory devices, traffic might stop between the SRX240 device and
the Cisco switch due to link mode mismatch. We recommend setting the same value
to the autonegotiation parameters on both ends.
•
On SRX100 devices, the link goes down when you upgrade FPGA on 1xGE SFP. As a
workaround, run the restart fpc command and restart the FPC.
•
On SRX210 devices with VDLS2, ATM COS VBR-related functionality cannot be tested.
Copyright © 2016, Juniper Networks, Inc.
Known Behavior
•
On SRX210 devices, IGMPv2 JOINS messages are dropped on an IRB interface. As a
workaround, enable IGMP snooping to use IGMP over IRB interfaces.
•
On all J Series devices, the DS3 interface does not have an option to configure
multilink-frame-relay-uni-nni (MFR).
•
On SRX210, SRX220, and SRX240 devices, every time the VDSL2 Mini-PIM is restarted
in the ADSL mode, the first packet passing through the Mini-PIM is dropped.
•
On all branch SRX Series devices, the RPM server operation does not work when the
probe is configured with the option destination-interface.
•
On all J Series devices, LLDP is not supported on routed ports.
•
In J Series xDSL PIMs, mapping between IP CoS and ATM CoS is not supported. If the
user configures IP CoS in conjunction with ATM CoS, the logical interface level shaper
matching the ATM CoS rate must be configured to avoid congestion drops in
segmentation and reassembly (SAR) as shown in the following example:
set interfaces at-5/0/0 unit 0 vci 1.110
set interfaces at-5/0/0 unit 0 shaping cbr 62400 ATM COS
set class-of-service interfaces at-5/0/0 unit 0 scheduler-map sche_map IP COS
set class-of-service interfaces at-5/0/0 unit 0 shaping-rate 62400 ADD IFL SHAPER
•
On SRX650 devices, MAC pause frame and FCS error frame counters are not supported
for the interfaces ge-0/0/0 through ge-0/0/3.
•
On SRX240 and SRX650 devices, the VLAN range from 3967 to 4094 falls under the
reserved VLAN address range, and the user is not allowed any configured VLANs from
this range.
•
On SRX650 devices, the last four ports of a 24-Gigabit Ethernet switch GPIM can be
used either as RJ-45 or small form-factor pluggable transceiver (SFP) ports. If both
are present and providing power, the SFP media is preferred. If the SFP media is removed
or the link is brought down, then the interface will switch to the RJ-45 medium. This
can take up to 15 seconds, during which the LED for the RJ-45 port might go on and off
intermittently. Similarly, when the RJ-45 medium is active and an SFP link is brought
up, the interface will transition to the SFP medium, and this transition could also take
a few seconds.
•
On SRX210 devices, the USB modem interface can handle bidirectional traffic of up
to 19 Kbps. On oversubscription of this amount (that is, bidirectional traffic of 20 Kbps
or above), keepalives do not get exchanged, and the interface goes down.
•
On SRX100, SRX210, SRX240, and SRX650 devices, on the Layer 3 ae interface, the
following features are not supported:
•
Encapsulations (such as CCC, VLAN CCC, VPLS, and PPPoE)
•
J-Web
•
10-Gigabit Ethernet
•
On SRX100 devices, the multicast data traffic is not supported on IRB interfaces.
•
On SRX240 High Memory devices, when the system login deny-sources statement is
used to restrict the access, it blocks a remote copy between nodes, which is used to

copy the configuration during the commit routine. Use a firewall filter on the lo0.0
interface to restrict the Routing Engine access, However, if you choose to use the system
login deny-sources statement, check the private addresses that were automatically
on lo0.x and sp-0/0/0.x and exclude them from the denied list.

•
On SRX100, SRX210, SRX220, SRX240, SRX650, and all J Series devices, on
VLAN-tagged routed interfaces, LLDP is not supported.
•
On SRX210 devices, the DOCSIS Mini-PIM delivers speeds up to a maximum of 100
Mbps throughput in each direction.
•
On SRX550 and SRX650 devices, the aggregate Ethernet (ae) interface with XE
member interface cannot be configured with the Ethernet switching family.
•
On all branch SRX Series and J Series devices, the Q-in-Q support on a Layer 3 interface
has the following limitations:
•
Double tagging is not supported on reth and ae interfaces.
•
Multitopology routing is not supported in flow mode and in chassis clusters.
•
Dual tagged frames are not supported on encapsulations (such as CCC, TCC, VPLS,
and PPPoE).
•
On Layer 3 logical interfaces, input-vlan-map, output-vlan-map, inner-range, and
inner-list are not applicable
•
Only TPIDs with 0x8100 are supported, and the maximum number of tags is 2.
•
Dual tagged frames are accepted only for logical interfaces with IPV4 and IPv6
families.
•
On SRX650 devices, LLDP is not supported on the base ports of the device and on the
2-Port 10 Gigabit Ethernet XPIM.
•
On SRX100, SRX110, SRX210, SRX220, SRX240, and SRX550 devices, LACP is not
supported on the 1-Port Gigabit Ethernet SFP Mini-PIM.

Intrusion Detection and Prevention (IDP)
•
On all branch SRX Series devices, from Junos OS Release 11.2 and later, the IDP security
package is based on the Berkeley database. Hence, when the Junos OS image is
upgraded from Junos OS Release 11.1 or earlier to Junos OS Release 11.2 or later, a
migration of IDP security package files needs to be performed. This is done
automatically on upgrade when the IDP process comes up. Similarly, when the image
is downgraded, a migration (secDb install) is automatically performed when the IDP
process comes up, and previously installed database files are deleted.
However, migration is dependent on the XML files for the installed database present
on the device. For first-time installation, completely updated XML files are required. If
the last update on the device was an incremental update, migration might fail. In such
a case, you have to manually download and install the IDP security package using the
download or install CLI command before using the IDP configuration with predefined
attacks or groups.
As a workaround, use the following CLI commands to manually download the individual
components of the security package from the Juniper Security Engineering portal and
install the full update:
•
request security idp security-package download full-update
•
request security idp security-package install
•
On all branch SRX Series devices, IDP does not allow header checks for nonpacket
contexts.
•
On SRX100, SRX210, SRX220, SRX240, and SRX650 devices, the maximum supported
number of entries in the ASC table is 100,000 entries. Because the user land buffer
has a fixed size of 1 MB as a limitation, the table displays a maximum of 38,837 cache
entries.
•
On all branch SRX Series devices, with regard to serialization limits, the maximum

•
On all branch SRX Series devices, all IDP policy templates are supported except All
Attacks. There is a 100 MB policy size limit for integrated mode and a 150 MB policy
size limit for dedicated mode. The current supported IDP policy templates are dynamic
based on the attack signatures added. Therefore, be aware that supported templates
might eventually grow past the policy size limit.
On all branch SRX Series devices, the following IDP policies are supported:
•
•
•
DMZ_Services
•
DNS_Service
•
File_Server
•
Getting_Started
•
IDP_Default
•
Recommended
•
Web_Server
On all branch SRX Series devices, IDP deployed in both active/active and active/passive
chassis clusters has the following limitations:
•
No inspection of sessions that fail over or fail back.
•
The IP action table is not synchronized across nodes.
•
The Routing Engine on the secondary node might not be able to reach networks that
are reachable only through a Packet Forwarding Engine.
•
The SSL session ID cache is not synchronized across nodes. If an SSL session reuses
a session ID and it happens to be processed on a node other than the one on which
the session ID is cached, the SSL session cannot be decrypted and will be bypassed
for IDP inspection.
On all branch SRX Series devices, IDP deployed in active/active chassis clusters has
a limitation that for time-binding scope source traffic, if attacks from a source (with
more than one destination) have active sessions distributed across nodes, then the
attack might not be detected because time-binding counting has a local-node-only
view. Detecting this sort of attack requires an RTO synchronization of the time-binding
state that is not currently supported.
NOTE: On SRX100 devices, IDP chassis cluster is supported in
active/backup mode.

•
Edit mode might overwrite outside configurations such as Custom Application, Policy
Name, and zone inbound services.
•
In create new mode, when you commit your configuration changes, your changes will
overwrite the existing configuration.
•
VPN and NAT wizards are not compatible with the New Setup wizard; therefore the
VPN or NAT wizard configuration will not be reflected in the New Setup wizard or vice
versa.
•
By default, 2 minutes are required to commit a configuration using the New Setup

Layer 2 Transparent Mode
•
DHCP server propagation is not supported in Layer 2 transparent mode.
•
Layer 2 Bridging and Transparent Mode— On all SRX Series devices, bridging and
transparent mode are not supported on Mini-Physical Interface Modules (Mini-PIMs).
Network Address Translation (NAT)
•
Single IP address in a source NAT pool without PAT—The number of hosts that a
source NAT pool without PAT can support is limited to the number of addresses in the
pool. When you have a pool with a single IP address, only one host can be supported,
and traffic from other hosts is blocked because there are no resources available.
If a single IP address is configured for a source NAT pool without PAT when NAT
resource assignment is not in active-backup mode in a chassis cluster, traffic through
node 1 will be blocked.
•
For all ALG traffic, except FTP, we recommend that you not use the static NAT rule
options source-address or source-port. Data session creation can fail if these options
are used, because the IP address and the source port value, which is a random value,
might not match the static NAT rule. For the same reason, we also recommend that
you not use the source NAT rule option source-port for ALG traffic.
For FTP ALG traffic, the source-address option can be used because an IP address can
be provided to match the source address of a static NAT rule.
Additionally, because static NAT rules do not support overlapping addresses and ports,
they should not be used to map one external IP address to multiple internal IP addresses
for ALG traffic. For example, if different sites want to access two different FTP servers,
the internal FTP servers should be mapped to two different external IP addresses.
•
Maximum capacities for source pools and IP addresses have been extended on SRX650
devices, as follows:

Increasing the capacity of source NAT pools consumes memory needed for port
allocation. When source NAT pool and IP address limits are reached, port ranges should

47
Junos OS 12.1X46 Release Notes
be reassigned. That is, the number of ports for each IP address should be decreased
when the number of IP addresses and source NAT pools is increased. This ensures NAT
does not consume too much memory. Use the port-range statement in configuration
mode in the CLI to assign a new port range or the pool-default-port-range statement
to override the specified default.
Configuring port overloading should also be done carefully when source NAT pools
are increased.
For source pool with PAT in range (63,488 through 65,535), two ports are allocated
at one time for RTP/RTCP applications, such as SIP, H.323, and RTSP. In these
scenarios, each IP address supports PAT, occupying 2048 ports (63,488 through
65,535) for ALG module use.
•
NAT rule capacity change—To support the use of large-scale NAT at the edge of the
carrier network, the device-wide NAT rule capacity has been changed.
The number of destination and static NAT rules has been incremented as shown in
Table 5 on page 48. The limitation on the number of destination-rule-set and
static-rule-set has been increased.
Table 5 on page 48 provides the requirements per device to increase the configuration
limitation as well as to scale the capacity for each device.

On all branch SRX Series devices, in case of SSL proxy, sessions are whitelisted based
on the actual IP address and not on the translated IP address. Because of this, in the
whitelist configuration of the SSL proxy profile, the actual IP address should be provided
and not the translated IP addresses.
Example:
Consider a destination NAT rule that translates destination IP address 20.20.20.20 to
5.0.0.1 using the following commands:
•
set security nat destination pool d1 address 5.0.0.1/32
•
set security nat destination rule-set dst-nat rule r1 match destination-address

Known Behavior
In the above scenario, to exempt a session from SSL proxy inspection, the following
IP address should be added to the whitelist:
•
set security address-book global address ssl-proxy-exempted-addr 20.20.20.20/32
•
set services ssl proxy profile ssl-inspect-profile whitelist ssl-proxy-exempted-addr
Power over Ethernet (PoE)
•
On SRX210-PoE devices, SDK packages might not work.
Security Policies
•
On all branch SRX Series devices, the current SSL proxy implementation has the
following connectivity limitations:
•
The SSLv2 protocol is not supported. SSL sessions using SSLv2 are dropped.
•
SSL sessions where client certificate authentication is mandatory are dropped.
•
SSL sessions where renegotiation is requested are dropped.
•
On all branch SRX Series devices, for a particular session, the SSL proxy is only enabled
if a relevant feature related to SSL traffic is also enabled. Features that are related to
SSL traffic are IDP, application identification, application firewall, and application
tracking. If none of the above listed features are active on a session, the SSL proxy
bypasses the session and logs are not generated in this scenario.
•
On all branch SRX Series and J Series devices, you cannot configure the following IP
addresses as negated addresses in a policy:
•
Wildcard addresses
•
IPv6 addresses
•
Addresses such as any, any-ipv4, any-IPv6, and 0.0.0.0
•
When a range of addresses or a single address is negated, it can be divided into multiple
addresses. These negated addresses are shown as a prefix or a length that requires
more memory for storage on a Packet Forwarding Engine.
•
Each platform has a limited number of policies with negated addresses. A policy can
contain 10 source or destination addresses. The capacity of the policy depends on the
maximum number of policies that the platform supports.
•
J Series devices do not support the authentication order password radius or password
ldap in the edit access profile profile-name authentication-order command. Instead, use
order radius password or ldap password.

Unified Access Control
•
During SRX device communication to the Infranet Controller (IC), the connection
remains in attempt-next state preventing a successful communication. This happens
when an outgoing interface used to connect the IC is a part of routing-instance.
Unified Threat Management (UTM)
•
The quarantine action is supported only for UTM Enhanced Web Filtering or Juniper
enhanced type of Web filtering.
•
On SRX550 devices configured with Sophos Antivirus, certain files whose sizes are
larger than the max-content-size might not go into fallback unlike other AV engines
and instead end up being detected as clean file for few protocols which does not
pre-declare the content size.
Upgrade and Downgrade
•
On all J Series devices, the Junos OS upgrade might fail due to insufficient disk space
if the CompactFlash is smaller than 1 GB in size. We recommend using a 1-GB compact
flash for Junos OS Release 10.0 and later.
•
On SRX100, SRX210, SRX220, SRX240, and SRX650 devices, when you connect a
client running Junos Pulse 1.0 to an SRX Series device that is a running a later version
of Junos Pulse, the client will not be upgraded automatically to the later version. You
must uninstall Junos Pulse 1.0 from the client and then download the later version of
Junos Pulse from the SRX Series device.
•
On the SRX240B2 and SRX240H2 models, when you try to upgrade from Junos OS
Release 11.4 to Junos OS Release 12.1X44, 12.1X45, 12.1X46, or 12.1X47, the upgrade fails
when attempting to validate the configuration. To resolve this, use the no-validate
option.
USB
•
On all branch SRX Series devices, frequent plug and play of USB keys is not supported.
You must wait for the device node creation before removing the USB key.
Virtual Private Networks (VPNs)
•
On all branch SRX Series devices, when you download the Pulse client using the Mozilla
browser, the “Launching the VPN Client” page is displayed when Junos Pulse is still
downloading. However, when you download the Pulse client using Microsoft Internet
Explorer, the “Launching the VPN Client” page is displayed after Junos Pulse has been
downloaded and installed.
•
On SRX100, SRX210, SRX240, and SRX650 devices, while configuring dynamic VPN
using the Junos Pulse client, when you select the authentication-algorithm as sha-256
in the IKE proposal, the IPsec session might not get established.

Junos OS 12.1X46 Release Notes
•
RIP is not supported in point-to-multipoint (P2MP) VPN scenarios including AutoVPN
deployments. We recommend OSPF or IBGP for dynamic routing when using P2MP
VPN tunnels.
•
On all branch SRX Series devices, configuring XAuth with AutoVPN secure tunnel (st0)
interfaces in point-to-multipoint mode and dynamic IKE gateways is not supported.
The IPv6 IPsec VPN implementation has the following limitations:
•
Devices with IPv6 addressing do not perform fragmentation. IPv6 hosts should either
perform path MTU discovery or send packets smaller than the IPv6 minimum MTU
size of 1280 bytes.
•
Because IPv6 addresses are 128 bits long compared to IPv4 addresses, which are
32-bits long, IPv6 IPsec packet processing requires more resources. Therefore, a small
performance degradation is observed.
•
The dynamic VPN server must be a standalone branch SRX Series device. The dynamic
VPN feature is not supported on high-end SRX Series devices or on branch SRX Series
devices in a chassis cluster.
•
The IPv6 IPsec VPN does not support the following functions:
•
Remote Access—XAuth, config mode, and shared IKE identity with mandatory XAuth
•
IKE authentication—PKI or DSA
•
IKE peer type—Dynamic IP
•
NAT-T
•
VPN monitoring
•
NHTB
•
Packet reordering for IPv6 fragments over tunnels is not supported
•
IPv6 link-local address
See VPN Feature Support for IPv6 Addresses for more information about IPv6 address
support in VPN features.
On all branch SRX Series devices, when you enable VPN, overlapping of the IP addresses
across virtual routers is supported with following limitations:
•
An IKE external interface address cannot overlap with any other virtual router.
•
An internal/trust interface address can overlap across virtual routers.
•
An st0 interface address cannot overlap in route-based VPN in point-to-multipoint
tunnels such as NHTB.
•
An st0 interface address can overlap in route-based VPN in point-to-point tunnels.
SRX100, SRX210, and SRX240 devices have the following limitations:

Resolved Issues - 12.1X46-D35
Application Identification
•
On all branch SRX Series devices running Junos OS Release 12.1X46 and earlier, if
application identification (AppID) is enabled, performance degradation is seen in
comparison with devices running Junos OS Release 12.1X47-D10 and later. This is
because the AppID function does not ignore the related sessions when AppID has
reached the terminal state, and continues with the serialization processing for those
sessions. It is important to note that Junos OS Release 12.1X47 and later releases use
advanced AppID. PR1046509
Application Layer Gateways (ALGs)
•
On all branch SRX Series devices (except SRX110) in a chassis cluster with TCP-based
ALG enabled and the TCP keepalive mechanism used on the TCP server and client,
after a data plane Redundancy Group (RG1+) failover, the keep-alive message causes
the mbuf to be held by the ALG until the session timeout. As a result, a high mbuf usage
alarm is generated. Application communication failure occurs due to lack of mbuf.

Authentication
•
On all branch SRX Series devices with firewall authentication enabled, when a firewall

On all branch SRX Series devices in chassis cluster mode, during control plane RG0
failover, a policy resynchronization operation compares the policy message between
the Routing Engine and the Packet Forwarding Engine. However, some fields in the

Dynamic Host Configuration Protocol (DHCP)
•
On all branch SRX Series devices configured as a DHCP server (using the jdhcpd
process), when the DHCP server gets a new request from a client and applies an IP
address from the authentication process (authd), the jdhcpd process communicates
with authd process twice as expected (once for the DHCP discovery message and
once for the DHCP request message). If the authentication fails in the first message,
the authd process will indefinitely wait for the second authentication request. However,
the jdhcpd process never sends the second request, because the process detects that
the first authentication did not occur. This causes memory leak on the authd process,
and the memory might get exhausted, generating a core file and preventing DHCP
server service. High CPU usage on the Routing Engine might also be observed. PR1042818

On SRX240, SRX550, and SRX650 devices with IPsec VPN configured using IKE version
1, the device can hold only two pairs of IPsec security associations (SAs) per tunnel.
When the third IPsec SA rekey occurs, the oldest IPsec SA is deleted. Due to this
mechanism, a looping of IPsec SA rekey might occur. For example, when a VPN peer
contains incorrect configuration that has more than two proxy IDs matching only one
proxy ID on a device, the rekey looping issue might cause the flowd process to crash

On all branch SRX Series devices, for IDP, AppSecure, ALG, GTP, or SCTP, the flow
serialization impacts session performance. This flow serialization continues even after
Layer 7 processing is completed. PR986326
•
On all branch SRX Series devices in Layer 2 transparent mode, the flowd process might
crash when two packets with the same connections are received in a short time before
the flow session is created, and destination MAC address lookup succeeds for these
two packets. PR1025983
Interfaces and Routing
•
On SRX220 and SRX550 devices, you can configure a maximum of 250 connections
as connection-limit. However, 250 connections cannot be established. To set the

The SRX Series cluster is used as a VPN concentrator that is connected to remote VPN
clients. The Internet key exchange process (daemon) tries to reuse the IP address that
was previously assigned to an XAuth client. But the IKEd Xauth attributes are overwritten
when the authentication reply is received from Authd. This causes the IKEd to assign
a new IP address every time a Phase 1 Security Association (SA) is negotiated. As a
result, multiple remote clients cannot connect through VPN. PR854922

on the right side of the Junos OS for SRX Series Services Gateways, Release 12.1X46
index page.
•
(New) The Getting Started Guide for Branch SRX Series describes how to get up and
running with branch SRX Series devices.
•
(Expanded) The Junos OS Monitoring and Troubleshooting Library for Security Devices
contains significantly more content to help network and security managers keep their
SRX Series devices running smoothly in their production environments.
•
(Expanded) The Junos OS for SRX Series Services Gateways, Release 12.1X46 index
page has been expanded to serve as a “one stop shop” for all of your Junos OS for SRX
Series technical documentation needs.
Junos OS Release Notes
In Junos OS 12.1X46-D10 Release Notes and Junos OS 12.X46-D15 Maintenance Release
Notes, the SCCP ALG feature description has the following incorrect information:
Support for SCCP v20—This feature is supported on all SRX Series devices.
Starting in Junos OS Release 12.1X46-D10, the SCCP ALG supports version 20. In SCCP
v20, several SCCP messages have been updated with a new format.
The correct information is as follows:
Support for SCCP v20—This feature is supported on all SRX Series devices. Starting in
Junos OS Release 12.1X46-D10, the SCCP ALG supports SCCP versions 16, 17, and 20 and
several SCCP messages have been updated with a new format. Cisco Call Manager (CM)
version 7 uses SCCP version 20.

Chassis Cluster Feature Guide for Security Devices
•
Under the Configuration tab, in the Example: Configuring an SRX Series Services
Gateway for the Branch as a Chassis Cluster, there is a correction in Table 2: SRX Series
Services Gateways fxp0 and fxp1 Interfaces Mapping. For the SRX210, the fxp0 Interface
should not be ge-0/0/0; it should be fe-0/0/6.
•
The set chassis cluster cluster-id cluster-id node node rebootoperational mode command
is missing from the Administration tab. This operational mode command sets the
chassis cluster identifier (ID) and node ID on each device, and reboots the devices to
enable clustering. This command has two options: cluster-id cluster-id (0 through 255)
and node node (0 or 1). The system uses the chassis cluster ID and chassis cluster node
ID to apply the correct configuration for each node (for example, when you use the
apply-groups command to configure the chassis cluster management interface). The
chassis cluster ID and node ID statements are written to the EPROM, and the statements
take effect when the system is rebooted. Setting a cluster ID to 0 is equivalent to
disabling a cluster. Support for extended cluster identifiers (more than 15 identifiers)
added in Junos OS Release 12.1X46-D10. A cluster ID greater than 15 can only be set
when the fabric and control link interfaces are connected back-to-back. The command
has the following privilege level: maintenance.

Junos OS 12.1X46 Release Notes
If you have a cluster set up and running with an earlier release of Junos OS, you can
upgrade to Junos OS Release 12.1X46-D10 or later and re-create a cluster with cluster
IDs greater than 16. If for any reason you decide to revert to the previous version of
Junos OS that did not support extended cluster IDs, the system comes up with
standalone devices after you reboot. If the cluster ID set is less than 16 and you roll
back to a previous release, the system comes back with the previous setup.

SRX240 Services Gateway Hardware Guide
•
In the “Connecting the SRX240 Services Gateway to the J-Web Interface” section, the
following information is missing in the note:
NOTE: Microsoft Internet Explorer version 6.0 is also supported as
backward compatible from Microsoft Internet Explorer version 7.0.
•
The “Maintaining the SRX650 Services Gateway Power Supply” section incorrectly
states that the status of the power supplies on the SRX650 Services Gateway can be
checked by issuing the show chassis environment pem command. The show chassis
environment pem command is not supported on the SRX650 Services Gateway.

Several tasks are listed in the wrong order. “Task 6: Connect the External Antenna”
should appear before “Task 3: Check the 3G ExpressCard Status,” because the user
needs to connect the antenna before checking the status of the 3G ExpressCard. The
correct order of the tasks is as follows:

Migration, Upgrade, and Downgrade Instructions
1.
Install the 3G ExpressCard
2. Connect the External Antenna
3. Check the 3G ExpressCard Status
4. Configure the 3G ExpressCard
5. Activate the 3G ExpressCard Options
•
In “Task 6: Connect the External Antenna,” the following sentence is incorrect and
redundant: “The antenna has a magnetic mount, so it must be placed far away from
radio frequency noise sources including network components.”
•
In the “Frequently Asked Questions” section, the answer to the following question
contains an inaccurate and redundant statement:
Q: Is an antenna required? How much does it cost?
A: The required antenna is packaged with the ExpressCard in the SRX210 Services
Gateway 3G ExpressCard kit at no additional charge. The antenna will have a magnetic
mount with ceiling and wall mount kits within the package.
In the answer, the sentence “The antenna will have a magnetic mount with ceiling and
wall mount kits within the package” is incorrect and redundant.

Upgrading an AppSecure Device
Use the no-validate Option for AppSecure Devices.
For devices implementing AppSecure services, use the no-validate option when upgrading
from Junos OS Release 11.2 or earlier to Junos OS 11.4R1 or later. The application signature
package used with AppSecure services in previous releases has been moved from the
configuration file to a signature database. This change in location can trigger an error
during the validation step and interrupt the Junos OS upgrade. The no-validate option
bypasses this step.
Network and Security Manager Support
Network and Security Manager (NSM) support for SRX Series Services Gateways and J
Series Services Routers with Junos OS 12.1X46-D10 is available only with NSM versions
2012.2R6 / 2012.1R10 and later. For additional information, see Network and Security
Manager documentation.
Upgrade and Downgrade Scripts for Address Book Configuration
Beginning with Junos OS Release 12.1, you can configure address books under the [security]
hierarchy and attach security zones to them (zone-attached configuration). In Junos OS
Release 11.1 and earlier, address books were defined under the [security zones] hierarchy
(zone-defined configuration).
You can either define all address books under the [security] hierarchy in a zone-attached
configuration format or under the [security zones] hierarchy in a zone-defined configuration
format; the CLI displays an error and fails to commit the configuration if you configure
both configuration formats on one system.
Juniper Networks provides Junos operation scripts that allow you to work in either of the
address book configuration formats (see Figure 1 on page 95).

About Upgrade and Downgrade Scripts
After downloading Junos OS Release 12.1, you have the following options for configuring
the address book feature:
•
Use the default address book configuration—You can configure address books using
the zone-defined configuration format, which is available by default. For information
on how to configure zone-defined address books, see the Junos OS Release 11.1
documentation.
•
Use the upgrade script—You can run the upgrade script available on the Juniper Networks
support site to configure address books using the new zone-attached configuration
94

Migration, Upgrade, and Downgrade Instructions
format. When upgrading, the system uses the zone names to create address books.
For example, addresses in the trust zone are created in an address book named
trust-address-book and are attached to the trust zone. IP prefixes used in NAT rules
remain unaffected.
After upgrading to the zone-attached address book configuration:
•
You cannot configure address books using the zone-defined address book
configuration format; the CLI displays an error and fails to commit.
•
You cannot configure address books using the J-Web interface.
For information on how to configure zone-attached address books, see the Junos OS
Release 12.1 documentation.
•
Use the downgrade script—After upgrading to the zone-attached configuration, if you
want to revert to the zone-defined configuration, use the downgrade script available
on the Juniper Networks support site. For information on how to configure zone-defined
address books, see the Junos OS Release 11.1 documentation.
NOTE: Before running the downgrade script, make sure to revert any
configuration that uses addresses from the global address book.

Junos OS 12.1X46 Release Notes
Running Upgrade and Downgrade Scripts
The following restrictions apply to the address book upgrade and downgrade scripts:
•
The scripts cannot run unless the configuration on your system has been committed.
Thus, if the zone-defined address book and zone-attached address book configurations
are present on your system at the same time, the scripts will not run.
•
The scripts cannot run when the global address book exists on your system.
•
If you upgrade your device to Junos OS Release 12.1 and configure logical systems, the
master logical system retains any previously configured zone-defined address book
configuration. The master administrator can run the address book upgrade script to
convert the existing zone-defined configuration to the zone-attached configuration.
The upgrade script converts all zone-defined configurations in the master logical system
and user logical systems.
NOTE: You cannot run the downgrade script on logical systems.
For information about implementing and executing Junos operation scripts, see the Junos
OS Configuration and Operations Automation Guide.
Upgrade and Downgrade Support Policy for Junos OS Releases and Extended End-Of-Life
Releases
Support for upgrades and downgrades that span more than three Junos OS releases at
a time is not provided, except for releases that are designated as Extended End-of-Life
(EEOL) releases. EEOL releases provide direct upgrade and downgrade paths—you can
upgrade directly from one EEOL release to the next EEOL release even though EEOL
releases generally occur in increments beyond three releases.
You can upgrade or downgrade to the EEOL release that occurs directly before or after
the currently installed EEOL release, or to two EEOL releases before or after. For example,
Junos OS Releases 10.0, 10.4, and 11.4 are EEOL releases. You can upgrade from Junos OS
Release 10.0 to Release 10.4 or even from Junos OS Release 10.0 to Release 11.4. However,
you cannot upgrade directly from a non-EEOL release that is more than three releases
ahead or behind. For example, you cannot directly upgrade from Junos OS Release 10.3
(a non-EEOL release) to Junos OS Release 11.4 or directly downgrade from Junos OS
Release 11.4 to Junos OS Release 10.3.
To upgrade or downgrade from a non-EEOL release to a release more than three releases
before or after, first upgrade to the next EEOL release and then upgrade or downgrade
from that EEOL release to your target release.
For more information about EEOL releases and to review a list of EEOL releases, see
http://www.juniper.net/support/eol/junos.html.

Hardware Requirements
Transceiver Compatibility for SRX Series and J Series Devices
We strongly recommend that only transceivers provided by Juniper Networks be used
on SRX Series and J Series interface modules. Different transceiver types (long-range,
short-range, copper, and others) can be used together on multiport SFP interface modules
as long as they are provided by Juniper Networks. We cannot guarantee that the interface
module will operate correctly if third-party transceivers are used.
Please contact Juniper Networks for the correct transceiver part number for your device.
Power and Heat Dissipation Requirements for J Series PIMs
On J Series Services Routers, the system monitors the PIMs and verifies that the PIMs
fall within the power and heat dissipation capacity of the chassis. If power management
is enabled and the capacity is exceeded, the system prevents one or more of the PIMs
from becoming active.
CAUTION: Disabling the power management can result in hardware damage
if you overload the chassis capacities.
You can also use CLI commands to choose which PIMs are disabled. For details about
calculating the power and heat dissipation capacity of each PIM and for troubleshooting
procedures, see the J Series Services Routers Hardware Guide.
Supported Third-Party Hardware
The following third-party hardware is supported for use with J Series Services Routers
running Junos OS.
•
USB Modem
We recommend using a U.S. Robotics USB 56K V.92 Modem, model number USR 5637.
•
Storage Devices
The USB slots on J Series Services Routers accept a USB storage device or USB storage
device adapter with a CompactFlash card installed, as defined in the CompactFlash
Specification published by the CompactFlash Association. When the USB device is
installed and configured, it automatically acts as a secondary boot device if the primary
CompactFlash card fails on startup. Depending on the size of the USB storage device,
you can also configure it to receive any core files generated during a router failure. The
USB device must have a storage capacity of at least 256 MB.
Table 8 on page 97 lists the USB and CompactFlash card devices supported for use
with the J Series Services Routers.

Junos OS 12.1X46 Release Notes
Release 12.1X46-D30 Software Features
Application Layer Gateways (ALGs
•
MS-RPC ALG and Sun RPC ALG map table scaling for SRX Series devices— Starting
with Junos OS Release 12.1x46-D30, the MS-RPC ALG and Sun RPC ALG dynamically
allocate new mapping entries instead of using a default size (512 entries). They also
offer a flexible time-based RPC mapping entry that removes the mapping entry
(auto-clean) without affecting the associated active RPC sessions, including both
control session and data session.
[See RPC ALG Feature Guide for Security Devices.]
Release 12.1X46-D25 Software Features
General Packet Radio Service Feature Guide for Security Devices
•
GTP GSN Table Ager [High-end SRX Series]—One SRX Series device supports a total
of 36,000 GSN entries, each of which was saved permanently prior to this release. To
prevent GSN entry exhaustion caused by frequent short-time roaming among countries,
visiting GSNs are recorded when subscribers access the home GPRS core network
from visiting countries. These entries are not deleted when the subscribers return home,
but no further traffic is passed. The GTP GSN table ager causes the idling GSN entries
to time out, preventing inactive GSNs from taking up too much space.
[See the “General Packet Radio Service” section in the Junos OS 12.1X46-D25 Feature
Guide.]
TCP/TLS support for real time logging
•
TCP/TLS support for real-time logging [High-end SRX Series]—Starting in Junos OS
Release 12.1X46-D25, a secure mechanism, enabled through a plug-in during system
initialization, encrypts and transports dataplane syslog messages to TLS-capable
syslog receivers (such as the Juniper Networks STRM or a standards-based third-party
device) over TCP. The SPU generates the log data. By default, port 514 is used for TCP
logging and port 6514 is used for TLS logging. As a log client, a TCP/TLS connection
is initiated to the log server.
[See the “Syslog Messages” section in the Junos OS 12.1X46-D25 Release Feature
Guide.]
Release 12.1X46-D20 Software Features
Chassis Cluster
•
100
Autorecovery of fabric link [SRX Series]—The fabric link feature supports autorecovery,
which includes the following enhancements:
•
Fabric monitoring feature is enabled by default on high-end SRX Series, and hence
recovery of fabric link and synchronization takes place automatically.
•
If the fabric link goes down, RG1+ becomes ineligible on either the secondary node
or the node with failures, by default. The node remains in this state until the fabric
link comes up or the other node goes away.
Copyright © 2016, Juniper Networks, Inc.
New and Changed Features
•
If the fabric link goes down followed by the control link, then after approximately 66
seconds the secondary node (or the node with failures) assumes that the remote
node is dead and takes over as the primary node.
[See Understanding Chassis Cluster Fabric Links.]
•
Enhanced debugging support for chassis cluster [SRX Series]—The chassis cluster
debugging functionality has the following enhancements:
•
The show chassis cluster status command output includes failure reasons (acronyms
and their expansions) when the redundancy group's priority is zero.
•
Cleaner jsrpd process includes removing unwanted logs and moving the debug log
message from level LOG_INFO to LOG_DEBUG.
•
The show chassis cluster information command output displays redundancy group,
LED, and monitored failure details.
•
SNMP traps send messages when a node's weight goes down and also when it
recovers.
•
The show chassis cluster ip-monitoring command output displays both the global
threshold and the current threshold of each node and displays the weight of each
monitored IP address.
•
A syslog message appears when the control link goes down.
[See show chassis cluster ip-monitoring status.]
Copyright © 2016, Juniper Networks, Inc.
101
Junos OS 12.1X46 Release Notes
Public Key Infrastructure (PKI)
•
Online Certificate Status Protocol (OCSP) [SRX Series]—OCSP, like CRL, checks the
revocation status of X509 certificates. Requests are sent to the OCSP server(s)
configured in a CA profile with the ocsp url statement at the [edit security pki ca-profile
profile-name revocation-check] hierarchy level. The use-ocsp option must also be
configured. If there is no response from the OCSP server, the request is then sent to
the location specified in the certificate's AuthorityInfoAccess extension.
[See the “Public Key Infrastructure (PKI)” section in the Junos OS 12.1X46-D20 Feature
Guide.]
Routing Protocols
•
OSPFv3 IPsec authentication and confidentiality [SRX Series]—OSPF for IPv6, also
known as OSPF version 3 (OSPFv3), does not have built-in authentication to ensure
that routing packets are not altered and re-sent to the router. In Junos OS Release
12.1X46-D20, IPsec can be used to secure OSPFv3 interfaces and virtual links and
provide encryption for OSPF packets.
To configure IPsec for OSPF/OSPFv3, define a security association (SA) with the
security-association sa-name configuration option at the [edit security ipsec] hierarchy
level. The configured SA is then applied it to the OSPF/OSPFv3 interface or virtual link
configuration.
[See the “Routing Protocols” section in the Junos OS 12.1X46-D20 Feature Guide.]
Unified Threat Management (UTM)
•
UTM on next-generation SPC [SRX5400, SRX5600 and SRX5800]—This feature
provides support for UTM features, including Sophos antivirus, content filtering,
antispam, and enhanced Web filtering on next-generation SPCs.
•
UTM license enforcement [SRX Series]—License enforcement is supported for UTM
features, including Sophos antivirus, enhanced Web filtering, and antispam filtering
on all high-end SRX Series devices in addition to branch SRX Series devices. You can
add or remove UTM licenses on SRX Series devices. Each feature license is tied to
exactly one software feature and is valid for exactly one device.
Table 10 on page 102 lists the license modules and the license names.

VPNs
•
HMAC-SHA-256-128 authentication [High-end SRX Series]—Starting with Junos OS
Release 12.1X46-D20, HMAC-SHA-256-128 authentication is supported for IPsec
proposals and manual security associations on high-end SRX Series devices. You can
specify the hmac-sha-256-128 option at the [edit security ipsec proposal proposal-name]
and the [edit security ipsec vpn vpn-name manual] hierarchy levels.
[See the “VPNs” section in the Junos OS 12.1X46-D20 Feature Guide.]
Release 12.1X46-D15 Software Features
Routing Protocols
•
OSPFv2 support [High-end SRX Series]—OSPFv2 interfaces are supported on
nonbroadcast multiaccesss (NBMA) networks and point-to-point access networks
on high-end SRX Series devices.
When you configure OSPFv2 on an NBMA network, OSPFv2 operates by default in
point-to-multipoint mode. In this mode, OSPFv2 treats the network as a set of
point-to-point links. Because there is no autodiscovery mechanism, you must configure
each neighbor.
An NBMA interface behaves similarly to a point-to-multipoint interface but requires
election and operation of a designated router and a backup designated router.
Use the following CLI commands to configure an OSPFv2 interface on an NBMA or a
point-to-multipoint network:
•
set protocols ospf area area-number interface interface-name neighbor
address-of-neighbor
•
set protocols ospf area area-number interface interface-name interface-type
interface-type (nbma or p2mp)
[See “Routing Protocols” section in Junos OS 12.1X46-D15 Feature Guide.]
Release 12.1X46-D10 Software Features
Application Layer Gateways (ALGs)
•
ALG message buffer optimization—Starting in Junos OS Release 12.1X46-D10, the
ALG message buffer optimization feature is enhanced to reduce high memory
consumption. This feature is supported on all SRX Series and J Series devices.
A message buffer is allocated only when the packet is ready to process. The buffer is
freed after the packet completes ALG handling, including modifying the payload,
performing NAT, opening a pinhole for a new connection between a client and a server,
Copyright © 2016, Juniper Networks, Inc.
103
Junos OS 12.1X46 Release Notes
and transferring data between a client and a server located on opposite sides of a
Juniper Networks device.
This feature has the following enhancements:
•
Unnecessary objcache buffering is avoided, resulting in low memory utilization.
•
jbuf manipulation is used to simplify the message buffer logic.
•
Full-fledged message buffer support for ALG line breaker is more flexible.
•
ALG Manager and ALG plug-in logic clarity are optimized.
[See alg-manager.]
•
IPv6 support for PPTP ALG—Starting with Junos OS Release 12.X46, this feature is
supported on all SRX Series devices.
PPTP ALG provides an ALG for the Point-to-Point Tunneling Protocol (PPTP). The
PPTP is a Layer 2 protocol that tunnels PPP data across TCP/IP networks. The PPTP
client is freely available on Windows systems and popularly applied on Linux systems;
it is widely deployed for building VPNs.
To support IPv6, the PPTP ALG parses both IPv4 and IPv6 PPTP packets, performs
NAT, and then opens a pinhole for the data tunnel. The flow module supports IPv6 to
parse the GRE packet and use the GRE call ID as fake port information to search the
session table and gate table.
[See PPTP ALG Feature Guide for Security Devices.]
•
IPv6 support for RTSP ALG—This feature is supported on all SRX Series and J Series
devices.
RTSP (Real-Time Streaming Protocol) is an Application Layer protocol for controlling
the delivery of data with real-time properties. The RTSP ALG accesses existing media
files over the network and controls the replay of the media.
Starting with Junos OS Release 12.1X46-D10, IPv6 is supported on the RTSP ALG along
with NAT-PT mode and NAT64 address translation.
This feature enables the RTSP ALG to parse IPv6 RTSP packets, open an IPv6 pattern
pinhole, and translate the Layer 7 IPv6 address according to the NAT configuration.
Also, support for IPv6 RTSP transaction pass through under permission policy and
IPv6 RTSP transaction pass through under NAT-PT and NAT 64 are enabled.
[See SIP RTSP ALG Feature Guide for Security Devices.]
•
IPv6 support for SIP ALG—This feature is supported on all SRX Series and J Series
devices.
Starting with Junos OS Release 12.1X46-D10, IPv6 is supported on the SIP ALG along
with NAT-PT mode and NAT64 address translation.
The SIP ALG processes the IPv6 address in the same way it processes the IPv4 address
for updating the payload if NAT is configured and opening pinholes for future traffic.
NAT-PT is implemented by normal NAT from IPv6 address to IPv4 address and vice
versa. The SIP ALG processes those address translation in payload just as the addresses
are processed in normal NAT.
104
Copyright © 2016, Juniper Networks, Inc.
New and Changed Features
NAT64 is a mechanism to allow IPv6 hosts to communicate with IPv4 servers. NAT64
is required to keep the IPv6 to IPv4 address mapping.
Previously Session Traversal Utilities for NAT (STUN) worked without the SIP ALG.
This means that the SIP ALG was not involved when persistent NAT was configured.
Starting with Junos OS Release 12.1X46-D10, STUN can coexist with the SIP ALG and
SIP ALG is involved when persistent NAT is configured.
[See SIP ALG Feature Guide for Security Devices.]
Chassis Cluster
•
Chassis cluster—Starting in Junos OS Release 12.1X46-D10, the SRX5K-MPC adds the
support of using 40-Gigabit Ethernet and 100-Gigabit Ethernet ports as chassis cluster
fabric ports. This feature is supported on the SRX5400, SRX5600, and SRX5800. This
enhancement saves one more slot on chassis and also improves chassis cluster fabric
link performance. In addition, you can also use 10G port on SRX5K-MPC as fabric port
with a 10x10GE MIC installed on it.
[See Understanding Chassis Cluster Fabric Links.]
Dynamic Host Configuration Protocol (DHCP)
•
DHCP relay—Starting in Junos OS Release 12.1X46-D10, this feature is supported on
all high-end SRX Series devices.
The existing DHCP relay feature has been enhanced to include support for high-end
SRX Series devices along with chassis cluster support.
You can configure DHCP relay options on the device and enable the device to function
as a DHCP relay agent. A DHCP relay agent forwards DHCP request and reply packets
between a DHCP client and a DHCP server.
To configure the DHCP relay agent on the device, include the dhcp-relay statement at
the [edit forwarding-options] hierarchy level.
[See Understanding DHCP Relay Agent Operation.]
Flow and Processing
•
Enhanced IPv6 support for the screen feature—This feature is supported on all
high-end SRX Series devices.
IPv6 support is extended for the following screen features:
•
IPv6 extension header checking and filtering
•
IPv6 packet header checking and filtering
•
ICMPv6 checking and filtering
New statements and commands allow you to configure these enhancements using
security zones similar to previous screen configurations. You can enable, disable, and
update screens to drop packets, create logs, and provide increased statistics for IPv6
traffic.
Copyright © 2016, Juniper Networks, Inc.
105
Junos OS 12.1X46 Release Notes
NOTE: By default, IPv6 packets bypass the screen feature.
[See Understanding IPv6 Support for Screens.]
•
Enhancements to flow trace options—This feature is supported on all high-end SRX
Series devices.
Starting in Junos OS Release 12.1X46-D10, flow trace granularity has been enhanced
to filter logs effectively. As a result you can access relevant trace messages easily and
avoid large traces that slow down your system. You can set the level of message you
want displayed by using the new trace-level statement at the [edit security flow
traceoptions] hierarchy level. And, use new flags to trace additional operations such
as fragmentation, high availability, multicast, session, tunnel, and route.
[See traceoptions (Security Flow).]
•
Monitoring flow sessions—This feature is supported on all high-end SRX Series devices.
Beginning with Junos OS Release 12.1X46-D10, you can monitor flow using filters that
match different criteria (such as source and destination addresses). New operational
mode commands monitor security flow filter and monitor security flow file have been
added. These commands allow you to debug without having to commit or modify your
running configuration. Previously, you were required to commit the configuration to
turn on trace options, which could possibly change the state of your device.
[See Monitoring Security Flow Sessions Overview.]
General Packet Radio Service (GPRS)
•
NAT for GPRS tunneling protocol (GTP):—Starting in Junos OS Release 12.1X46-D10,
static NAT for GTP packets is supported on all high-end SRX Series devices.
This feature has the following enhancements:
•
For GTP, control (GTP-C), as part of the GPRS IP address negotiation, embedded
IP addresses are included in the packet data protocol (PDP) context request or
response messages.
•
For GTP, user plane (GTP-U), GTP-U carries encapsulated user payload in an IP
packet. When NAT is enabled, only the outer IP packet needs to be translated, the
embedded IP addresses will not be translated.
[See Understanding GTP-U Inspection.]
•
GTP unified in-service software upgrade support (ISSU)—Junos OS Release
12.1X46-D10 adds support for unified ISSU on the GPRS tunneling protocol (GTP). This
feature is supported on all high-end SRX Series devices.
GTP supports unified ISSU between two SRX Series devices running two different
Junos OS releases. Unified ISSU is applied on a chassis cluster, enabling a software
upgrade between two different Junos OS releases with no disruption on the control
plane and with minimal disruption of traffic.

New and Changed Features
Interfaces and Routing
•
Link aggregation—Starting in Junos OS Release 12.1X46-D10, the SRX5K-MPC supports
the LAG and LACP features on the SRX5400, SRX5600, and SRX5800.
The following LAG and LACP features are supported:
•
Increases bandwidth, provides graceful degradation as failure occurs, and increases
availability.
•
Provides network redundancy by load-balancing traffic across all available links. If
one of the links should fail, the system automatically load-balances traffic across
all remaining links.
•
Enables automatic addition and deletion of individual links to the aggregate bundle
without user intervention.
•
Provides link monitoring to check whether both ends of the bundle are connected
to the correct group, enables or disables link protection, configures the LACP interval,
and supports centralized and distributed modes.
[See LAG and LACP Support on the SRX5000 Module Port Concentrator.]
[See Understanding Aggregated Ethernet Interfaces.]
IP Spoofing
•
IP spoofing in transparent mode—Starting in Junos OS Release 12.1X46-D10, this
feature is supported on all high-end SRX Series devices.
The IP spoofing feature has been enhanced to include Layer 2 transparent mode
support. IP spoofing is most frequently used in denial-of-service attacks. In an IP
spoofing attack, the attacker gains access to a restricted area of the network and
inserts a false source address in the packet header to make the packet appear to come
from a trusted source. When SRX Series devices are operating in transparent mode,
the IP spoof-checking mechanism makes use of address book entries.
NOTE: IP spoofing in Layer 2 transparent mode does not support DNS and
wildcard addresses.
[See Understanding IP Spoofing in Layer 2 Transparent Mode.]

Virtual Private Networks (VPNs)
•
Enhanced X2 interface monitoring—This feature is supported on all SRX Series devices.
In an LTE mobile network, X2 interfaces are used to connect Evolved Node Bs (eNodeBs)
for signal handover, monitoring, and radio coverage. SRX Series devices connect these
eNodeBs using IPsec tunnels.
This feature enables you to monitor traffic between eNodeBs by snooping into the
clear text traffic as it flows from one IPsec tunnel to another. Use the monitor-filter
statement at the [edit security forwarding-options] hierarchy level to duplicate clear
text packets and send them to the physical interface. You can then use Ethereal or
other packet analyzers to verify or collect the X2 traffic.
[See Understanding X2 Traffic Monitoring . ]
•
Dead peer detection (DPD) enhancements—This feature is supported on all SRX
Series devices.
Copyright © 2016, Juniper Networks, Inc.
111
Junos OS 12.1X46 Release Notes
Network devices use the DPD protocol to verify the existence and availability of other
peer devices. The default DPD mode optimized sends probes if there is no incoming
IKE or IPsec traffic from the peer within a configured interval after outgoing packets
are sent to the peer. The always-send option sends DPD probes at configured intervals
regardless of traffic activity between peers. A new configuration option probe-idle-tunnel
at the [edit security ike gateway dead-peer-detection] hierarchy level sends DPD probes
when there is no incoming or outgoing IKE or IPsec traffic between peers.
NOTE: We recommend that you configure probe-idle-tunnel instead of
always-send.
For all DPD modes, Phase 1 and Phase 2 security associations are cleared if a specified
number of probes are sent with no response from the peer.
[See Understanding Dead Peer Detection.]
•
IPsec VPN performance enhancements—Starting in Junos OS Release 12.1X46-D10,
a new configuration statement, ipsec-performance-acceleration, has been introduced
under the [edit security flow] hierarchy to enable IPsec VPN performance acceleration.
This feature is supported on SRX3400, SRX3600, SRX5600, and SRX5800 devices.
By default, VPN performance acceleration is disabled on SRX Series devices. Enabling
VPN performance acceleration can improve VPN throughput under certain conditions.
The following functions are not supported:
•
•
VPN traffic ACL accounting on physical egress and ingress interface
•
VPN traffic physical interface filter-based policer
•
VPN traffic physical interface QoS feature (classifier, remarking, scheduling, and
shaping)
Multiple traffic selectors on a route-based VPN—This feature is supported on all SRX
Series devices.
A traffic selector (also known as a proxy ID in IKEv1) is an agreement between IKE peers
to permit traffic through a tunnel if the traffic matches a specified pair of local and
remote addresses. With this feature, you can define multiple traffic selectors within a
specific route-based VPN, resulting in a unique SA for each traffic selector configured.
Only traffic that conforms to a traffic selector is permitted through the associated
IPsec SA.
To configure a traffic selector, use the traffic-selector configuration statement at the
[edit security ipsec vpn vpn-name] hierarchy level. The traffic selector pair is defined
with the mandatory local-ip ip-address and remote-ip ip-address statements. The CLI
operational command show security ipsec security-association traffic-selector
traffic-selector displays SA information for the specified traffic selector.
[See Understanding Traffic Selectors in Route-Based VPNs.]
•
112
Support for IPv6 address encapsulation in route-based one-to-one site-to-site VPN
tunnels—This feature is supported on all SRX Series devices.
Copyright © 2016, Juniper Networks, Inc.
New and Changed Features
In tunnel mode, IPsec encapsulates the original IP datagram—including the original IP
header—within a second IP datagram. The outer IP header contains the IP address of
the gateway, while the inner header contains the ultimate source and destination IP
addresses. The outer and inner IP headers can have a protocol field of IPv4 or IPv6. As
of Junos OS Release 12.1X46-D10, the following tunnel modes are supported on SRX
Series devices:
•
IPv4-in-IPv4 tunnels encapsulate IPv4 packets inside IPv4 packets.
•
IPv6-in-IPv6 tunnels encapsulate IPv6 packets inside IPv6 packets.
•
IPv6-in-IPv4 tunnels encapsulate IPv6 packets inside IPv4 packets.
•
IPv4-in-IPv6 tunnels encapsulate IPv4 packets inside IPv6 packets.
There are no new CLI configuration statements for this feature.
IPv4 and IPv6 traffic can be routed into a single IPv4 or IPv6 tunnel; the st0 interface
bound to the tunnel must be configured for both family inet and family inet6. Dual
stack tunnels—parallel IPv4 and IPv6 tunnels over a single physical external interface
to different VPN peers—are also supported.
[See VPN Feature Support for IPv6 Addresses.]
•
IKEv2 configuration payload support with RADIUS—This feature is supported on all
SRX Series devices.
Configuration payload is an Internet Key Exchange (IKE) version 2 feature used to
propagate provisioning information from an IKE responder to the IKE initiator. Starting
with Junos OS Release 12.1X46-D10, IKEv2 configuration payload is supported with
route-based VPNs only. The following attribute types, defined in RFC 5996, Internet
Key Exchange Protocol Version 2 (IKEv2), can be returned to the IKE initiator by the IKE
responder:
•
INTERNAL_IP4_ADDRESS
•
INTERNAL_IP4_NETMASK
•
INTERNAL_IP4_DNS
For the IKE responder to provide the initiator with provisioning information, it must
acquire the information from a specified source such as a RADIUS server. Provisioning
information can also be returned from a DHCP server through a RADIUS server. On the
RADIUS server, the user information should not include an authentication password.
As in previous Junos OS releases for the SRX Series, the RADIUS server profile is bound
to the IKE gateway using the xauth access-profile profile-name configuration at the
[edit security ike gateway gateway-name] hierarchy level.
This feature is supported only for point-to-multipoint secure tunnel (st0) interfaces.
For point-to-multipoint interfaces, the interfaces must be numbered and the addresses
in the configuration payload INTERNAL_IP4_ADDRESS attribute type must be within
the subnetwork range of the associated point-to-multipoint interface.
NOTE: IKEv2 on SRX Series devices does not support policy-based VPNs
or VPN monitoring.

Junos OS 12.1X46 Release Notes
[See Understanding Internet Key Exchange Version 2.]
•
IKEv2 with NAT-T and dynamic endpoint VPN—This feature is supported on all SRX
Series devices.
Starting with Junos OS 12.1X46-D10, both IKEv2 initiators and responders in a
route-based VPN can be behind NAT devices. The IKEv2 NAT-T feature supports IPsec
traffic that crosses NAT devices. Static NAT and dynamic NAT are supported. In static
NAT, there is a one-to-one relationship between the private and the public addresses.
In dynamic NAT, there is a many-to-one or many-to-many relationship between the
private and public addresses.
Dynamic endpoint (DEP) VPN is a Junos OS feature that covers IKEv2 initiator and
responder perspectives. From the initiator’s perspective, DEP VPN covers the situation
where the IKE external interface address is not fixed and is therefore not known by the
responder. This situation can occur when the peer’s address is dynamically assigned
by an ISP or when the peer’s connection crosses a NAT device that allocates addresses
from a dynamic address pool. From the responder’s perspective, DEP VPN describes
either a finite number of VPNs that are created for a number of VPN peers in a
many-to-many scenario or a shared VPN in a many-to-one scenario.
Starting with Junos OS 12.1X46-D10, the default value for the nat-keepalive option
configured at the [edit security ike gateway gateway-name] hierarchy level has been
changed from 5 seconds to 20 seconds.
[See Understanding NAT-T.]
Web Authentication
•
Web-redirect firewall authentication—Starting in Junos OS Release 12.1X46-D10, Web
authentication redirect enhancement is provided on all SRX Series devices.
With this feature, when you attempt to initiate a connection across the firewall, after
successful authentication the browser launches your original destination URL without
your needing to retype the URL.
The following message is displayed:
Redirecting to the original url, please wait

Junos OS 12.1X46 Release Notes
Application Firewall
•
Prior to Junos OS Release 12.1X46-D10, when a rule specifies dynamic-application
junos:HTTP without specifying any other nested application, the rule matches all HTTP
traffic whether the traffic contains a nested application or not.
In Junos OS Release 12.1X46-D15 and later, that functionality has changed. When a
rule specifies dynamic-application junos:HTTP, only HTTP traffic with no nested
members is matched.
Consider the following application firewall ruleset:
rule-sets http-ruleset {
rule rule1 {
match {
dynamic-application [junos:HTTP];
}
then {
deny;
}
}
default-rule {
permit;
}
}
Prior to Junos OS Release 11.4R6, the sample rules would be applied to traffic as shown
in the following list:
•
HTTP traffic with or without nested applications would be denied by rule1.
HTTP traffic with a nested application, such as junos:FACEBOOK or junos:TWITTER,
would be denied by rule1.
•
All other traffic would be permitted by the default rule.
In Junos OS Release 11.4R6 and later, the dynamic application junos:HTTP matches
only the HTTP traffic that contains no recognizable nested application. The sample
rules would now be applied differently:
•
Only the HTTP traffic with no nested application would be denied by rule1.
HTTP traffic with a nested application, such as junos:FACEBOOK or junos:TWITTER,
would no longer match rule1.
•
All other traffic would be permitted by the default rule.
HTTP traffic with a nested application, such as junos:FACEBOOK or junos:TWITTER,
would be permitted by the default rule.
•
In Junos OS Release 12.1X46-D10 and earlier, if a nested application is not configured
in any rule, then the nested application would match the default rule and take action
specified in the default rule.
Starting in Junos OS Release 12.1X46-D10, the functionality has changed. If a nested
application matches the default rule, then the application firewall uses the application
type to match the rule and takes action specified in the rule. Use the set security
118
Copyright © 2016, Juniper Networks, Inc.
Changes in Behavior and Syntax
application-firewall nested-application dynamic-lookup enable command to control
the behavior of the nested application, so that both the application and the nested
application are consistent.
The default behavior of nested application before Junos OS Release 12.1X46-D10:
•
Application firewall matches with the specific rule, if the nested application is
configured explicitly in a rule.
•
Application firewall matches with the default rule, if the nested application is not
configured explicitly in a rule.
•
Records the statistics of the application firewall in the matched rule.
The new behavior of nested application in Junos OS Release 12.1X46-D10:
•
Application firewall matches with an application rule during application firewall
policy lookup, if there is no explicit rule for the nested application.
•
Application firewall matches with a specific rule, if the nested application is configured
explicitly in a rule.
•
Records the statistics of the application firewall in the matched rule.
Application Layer Gateways (ALGs)
•
On all high-end SRX Series devices, with default configuration SQL ALG is disabled. If
you require SQL ALG configurations, then you need to enable the SQL ALG.
Application-Level Distributed Denial of Service
•
Application-level distributed denial of service, which is used to identify malicious bot
clients and to drop or deny traffic if requests exceed configured thresholds, will be
deprecated in future releases. As a replacement product for this feature, we recommend
that you migrate to the Juniper DDoS Secure product line. For more details, contact
your sales engineer.
Chassis Cluster
•
In Junos OS Release 12.1X46-D10 and earlier, in a chassis cluster mode, when a
secondary node failed, no notification was sent to report the secondary node failure.
Starting in Junos OS Release 12.1X46-D15, in a chassis cluster mode, when a secondary
node fails, the primary node sends the SNMP trap information to report secondary
node failures. New SNMP traps are added to report failures on the secondary node.
Sample SNMP trap sent when the monitored interface failed on the secondary node:

New or Changed CLI
•
In Junos OS releases earlier than Junos OS Release 12.1X46-D25, TACACS+ options
for authentication and accounting did not include an option for configuring a timestamp
and time zone.
In Junos OS Release 12.1X46-D25 and later releases, you can use the
timestamp-and-timezone option at the [edit system tacplus-options] hierarchy to
include start time, stop time, and time zone attributes in start/stop accounting records.
[See tacplus-options.]
•
On all high-end SRX Series devices, on SPC and next-generation SPCs, IDP dedicated
modes are supported only with the inline-tap option. In the inline-tap mode option, the
weight equal option is not supported.
Other IDP dedicated mode configurations such as dedicated weight IDP, dedicated
firewall, and dedicated equal are not supported.

displays a 1 in the full-cp-key field. Prior to this release, the output displayed a 0.
•
Prior to Junos OS Release 12.1X46-D10, when you configured the DNS proxy server
using the set system services dns dns-proxy view view-name domain domain-name
forwarder CLI statement, if the IP address specified in the forwarder option was not
available, the DNS query was forwarded to the default DNS servers (DNS servers
provided by the ISP). The device acquired the public IP addresses from the default
DNS servers.
Starting in Junos OS Release 12.1X46-D10, the forward-only option is added to the set
system services dns dns-proxy view view-name domain domain-name forward-only CLI
statement.
You can use the forward-only option to prevent the device from acquiring the public
IP addresses from the DNS servers (by terminating the DNS query) in cases when the
specified IP address is unreachable.

Compatibility
•
Version compatibility for Junos SDK—Beginning with Junos OS Release 12.1X44-D10,
Junos OS applications will install on the Junos OS only if the application is built with
the same release as the Junos OS release on which the application is being installed.
For example, an application built with Junos OS Release 12.1R2 will only install on Junos
OS Release 12.1R2 and will not install on Junos OS Release 12.1R1 or Junos OS Release
12.1R3.
Flow and Processing
SPU software changes for the SPC—The following changes apply to all high-end SRX
Series devices:
•
Each SPU runs a 64-bit FreeBSD kernel instead of the 32-bit FreeBSD kernel.
•
Each SPU runs a 64-bit flowd instead of the 32-bit version for increased scalability.
•
With the 64-bit OS, ksynd and ifstates on the SPU run in 64-bit mode.
•
TCP initial timeout enhancement–The minimum value you can configure for TCP
session initialization is 4 seconds. The default value is 20 seconds; if required you can
set the TCP session initialization value to less than 20 seconds.
•
Starting with Junos OS Release 12.1X46-D10, you can configure the timeout value for
a multicast flow session. In Junos OS Release 12.1X45-D10 and earlier, the timeout
value for a multicast flow session was based on the packet IP protocol, which was not
configurable.
Multicast flow sessions have one template flow session and one or more leaf sessions.
Because these sessions are linked together, they can have only one timeout value. The
earlier implementation ignored the configurable timeout values of individual policies
of each leaf session, and considered only the packet IP protocol timeout, which was
not configurable. For example, for UDP this timeout value was always 60 seconds. As
a result, multicast streams with a packet interval of more than 60 seconds experienced
premature aging-out of flow sessions and packet drops.
In the new implementation, multicast flow sessions consider the timeout values
configured in leaf session policies along with the IP protocol timeout values. The highest

123
Junos OS 12.1X46 Release Notes
of these timeout values is selected as the template session timeout. You can configure
the timeout value for the leaf session policy using custom applications.
[See Configuring the Timeout Value for Multicast Flow Sessions.]
•
On all high end SRX Series devices, you can configure the TCP session timeout in a
half-closed state by using the apply-to-half-close-state statement at the [edit security
flow tcp-session time-wait-state] hierarchy level. This enables the system to apply the
configured session timeout on receiving only one FIN packet (either client-to-server or
server-to-client). When this statement is not configured, the default behavior takes
effect, which is to apply the configured session timeout on receiving both the FIN
packets. The default TCP session timeout remains 150 seconds. [See
apply-to-half-close-state.]
Intrusion Detection and Prevention (IDP)
•
A system log message is generated when an IDP signature database update or policy
compilation fails with an empty dynamic group. The system-generated log message
is Dynamic Attack group [dyn_group_1] has no matching members found. Group is empty.
•
A new attribute, max-synacks-queued, is added to IDP sensor configuration TCP
reassembler. This attribute defines the maximum syn/ack queued with different SEQ
numbers and takes the values 0 through 5. Also, a new counter, Duplicate Syn/Ack
with different SEQ, is added to the IDP TCP reassembler. This counter displays the
number of syn/ack packets with different SEQ numbers.
•
New sensor configuration options have been added to log run conditions as IDP session
capacity and memory limits are approached, and to analyze traffic dropped by IDP
and application identification due to exceeding these limitations.
•
At start up, traffic is ignored by IDP by default if the IDP policy is not yet loaded. The
drop-if-no-policy-loaded option changes this behavior so that all sessions are dropped
before the IDP policy is loaded.
Use the following configuration command to drop traffic before the IDP policy is
loaded:
set security idp sensor-configuration flow drop-if-no-policy-loaded
The following new counters have been added to the show security idp counters flow
command output to analyze dropped traffic due to the drop-if-no-policy-loaded
option:
Sessions dropped due to no policy
•
0
By default, IDP ignores failover sessions in an SRX chassis cluster deployment. The
drop-on-failover option changes this behavior and automatically drops sessions that
are in the process of being inspected on the primary node when a failover to the
secondary node occurs.
Use the following configuration command to drop failover sessions:
set security idp sensor-configuration flow drop-on-failover
124
Copyright © 2016, Juniper Networks, Inc.
Changes in Behavior and Syntax
The following new counter has been added to the show security idp counters flow
command output to analyze dropped failover traffic due to the drop-on-failover
option:
Fail-over sessions dropped
•
0
By default, sessions are not dropped if the IDP session limit or resource limits are
exceeded. In this case, IDP and other sessions are dropped only when the device’s
session capacity or resources are depleted. The drop-on-limit option changes this
behavior and drops sessions when resource limits are exceeded.
Use the following configuration commands to set or remove the drop-on-limit option:
set security idp sensor-configuration flow drop-on-limit
delete security idp sensor-configuration flow drop-on-limit
The following new counters have been added to the show security idp counters flow
command output to analyze dropped IDP traffic due to the drop-on-limit option:
SM Sessions encountered memory failures
0
SM Packets on sessions with memory failures
0
SM Sessions dropped
0
Both directions flows ignored
0
IDP Stream Sessions dropped due to memory failure
0
IDP Stream Sessions ignored due to memory failure

0
Number of times Sessions exceed high mark
0
Number of times Sessions drop below low mark
0
Memory of Sessions exceeds high mark

The following counters have also been added to the show security idp counters
application-identification command output to analyze dropped application
identification traffic due to the drop-on-limit option:
AI-session dropped due to malloc failure before session create
0
AI-Sessions dropped due to malloc failure after create
0
AI-Packets received on sessions marked for drop due to malloc failure 0
The following options have been added to trigger informative log messages about
current run conditions. When set, the log messages are triggered whether the
drop-on-limit option is set or not.
•
The max-sessions-offset option sets an offset for the maximum IDP session limit.
When the number of IDP sessions exceeds the maximum session limit, a warning
is logged that conditions exist where IDP sessions could be dropped. When the
number of IDP sessions drops below the maximum IDP session limit minus the
offset value, a message is logged that conditions have returned to normal.

•
The min-objcache-limit-lt option sets a lower threshold for available cache memory.
The threshold value is expressed as a percentage of available IDP cache memory.
If the available cache memory drops below the lower threshold level, a message
is logged stating that conditions exist where IDP sessions could be dropped because
of memory allocation failures. For example, the following message shows that
the IDP cache memory has dropped below the lower threshold and that a number
of sessions have been dropped:
Jul 19 04:07:33 4.0.0.254 RT_IDP: IDP_SESSION_LOG_EVENT: IDP: at 1374232053,
FPC 4 PIC 1 IDP total available objcache(used 4253368304, limit 7247757312)
drops below low mark 3986266515. IDP may drop new sessions. Total sessions
dropped 1002593.
Use the following configuration command to set the min-objcache-limit-lt option:
set security idp sensor-configuration flow min-objcache-limit-lt
lower-threshold-value
•
The min-objcache-limit-ut option sets an upper threshold for available cache
memory. The threshold value is expressed as a percentage of available IDP cache
memory. If available IDP cache memory returns to the upper threshold level, a
message is logged stating that available cache memory has returned to normal.
For example, the following message shows that the available IDP cache memory
has increased above the upper threshold and that it is now performing normally:
Jul 19 04:13:47 4.0.0.254 RT_IDP: IDP_SESSION_LOG_EVENT: IDP: at 1374232428,
FPC 4 PIC 1 IDP total available objcache(used 2782950560, limit 7247757312)
increases above high mark 4348654380. IDP working in normal mode. Total
sessions dropped 13424632.
NOTE: This message is triggered only if the lower threshold has been
reached and the available memory has returned above the upper
threshold. Fluctuations in available memory that dropped below the
upper threshold but did not fall below the lower threshold would not
trigger the message.
Use the following configuration commands to set the min-objcache-limit-ut option:
set security idp sensor-configuration flow min-objcache-limit-ut
upper-threshold-value
•
On all high-end SRX Series devices with a single session, when IDP is activated, the
upload and download speeds are slow when compared to the firewall performance
numbers.
To overcome this issue, a new CLI command, set security idp sensor-configuration ips
session-pkt-depth, is introduced, for which the session-pkt-depth sensor-configuration
value is global for any session.
126
Copyright © 2016, Juniper Networks, Inc.
Changes in Behavior and Syntax
The session-pkt-depth sensor-configuration value specifies the number of packets per
session that are inspected by IDP. Any packets beyond the specified value are not
inspected. For example, when session-pkt-depth sensor-configuration is configured as
“n”, the IDP inspection happens only for first (n-1) packets in that session. Packets from
the nth packet onwards are ignored by IDP.
The default value of session-pkt-depth sensor-configuration is zero. When the default
value of zero is used, the session-pkt-depth value is not addressed, and IDP performs
a full inspection of the session.

Junos OS 12.1X46 Release Notes
Logical Systems
•
In Junos OS releases earlier than Junos OS Release 12.1X46-D10, when a logical tunnel
interface with an IPv4 address and an Ethernet encapsulation type is configured, a
configuration check is performed to ensure that the address is not identical to its peer
logical tunnel interface address and that both addresses are on the same subnet.
However, when a logical tunnel interface with an IPv6 address and an Ethernet
encapsulation type is configured, no such configuration check is performed.
Starting in Junos OS Release 12.1X46-D10, a check is performed for IPv6 configurations.
However, this change can cause existing IPv6 configurations to fail.
Management Information Bases (MIBs)
•
On all high-end SRX Series devices in a chassis cluster, the calculation of the primary
and secondary node sessions in the JnxJsSPUMonitoringObjectsTable object of the
SPU monitoring MIB is incorrect. The MIB JnxJsSPUMonitoringCurrentTotalSession
incorrectly displays total sessions.
A doubled session count is displayed because the active and backup nodes are treated
as separate sessions, although these nodes are not separate sessions.
Count only the session numbers on the local node, thereby avoiding a double count,
and local total sessions are displayed.
The SPUMonitoringCurrentTotalSession object of the MIB adds information per each
SPU from the local node.
[See SNMP MIBS and Traps Reference for SRX1400 and SRX3000 Line Services
Gateways.]
[See SNMP MIBS and Traps Reference for SRX5000 Line Services Gateways.]
Network Time Protocol
•
When the NTP client or server is enabled in the edit system ntp hierarchy, the
REQ_MON_GETLIST and REQ_MON_GETLIST_1 control messages supported by the
monlist feature within the NTP might allow remote attackers, causing a denial of
service. To identify the attack, apply a firewall filter and configure the router's loopback
address to allow only trusted addresses and networks.
Policy Applications
•
In Junos OS releases earlier than Junos OS Release 12.1X46-D15, when you set the count
option on a security policy using the CLI statement security policies from-zone zone-name
to-zone zone-name policy policy-name then, the count is based on the number of packets
and bytes of all network traffic that the policy allows to pass through the device.
In Junos OS Release 12.1X46-D15 and later, when you set the count option, the count
is based on the number of packets and bytes of all network traffic the policy allows to
pass through the device in both directions: the originating traffic from the client to the
server (from the from-zone to the to-zone), and the return traffic from the server to
the originating client.

Changes in Behavior and Syntax
Security Policies
•
Security policies are stored in both the Routing Engine and the Packet Forwarding
Engine. When you modify the policies on the Routing Engine side, the policies are
synchronized to the Packet Forwarding Engine side when you commit the configuration.
The policies in the Routing Engine and Packet Forwarding Engine must always be in
synchronization for the configuration to commit successfully. Under certain
circumstances, policies in the Routing Engine and the Packet Forwarding Engine might
be out of sync resulting in generation of system core files upon commit completion.
Starting in Junos OS Release 12.1X44-D10, the synchronization mechanism of security
policies between the Routing Engine and the Packet Forwarding Engine is improved.
These improvements significantly lower the probability of security policies becoming
out of sync between the Routing Engine and the Packet Forwarding Engine.
However, if an out-of-sync condition occurs, the following error message will be
displayed when you attempt to commit a configuration:
Policy is out of sync between RE and PFE <SPU-name(s)>. Please resync before commit.
error: configuration check-out failed
To re-synchronize policies between the Routing Engine and the Packet Forwarding
Engine, you must:
•
Reboot the device (device in standalone mode)
•
Reboot both devices (devices in a chassis cluster mode)
Session Timeout for Reroute Failure
•
The route-change-timeout configuration statement at the [edit security flow] hierarchy
level sets the timeout when a session is rerouted but there is a reroute failure (for
example, the new route uses a different egress zone from the previous route). In previous
releases, the route-change-timeout statement was disabled by default. In Release
12.1X46-D10, the route-change-timeout configuration is enabled by default and the
default timeout value is 6 seconds.
Simple Network Management Protocol (SNMP)
•
On all high-end SRX Series devices, the screen SNMP trap jnxJsScreenCfgChange will
not be sent during reboot.
•
Prior to Junos OS Release 12.1X46-D20, the fault management system did not display
the SPUs of next-generation SPCs because the XLP PICs were not defined in the MIB
files. The Juniper MIBS jnxContentsType did not return the correct OID for
next-generation SPCs.
Starting in Junos OS Release 12.1X46-D20, the mib-jnx-chas-defines.txt MIB file is
updated with the jnxPicType1ASPCXLP XLP PIC. Use the show snmp mib walk
jnxContentsType command to display the details for the XLP PIC.
Sample output displaying the incorrect OID:

System Logs
•
In Junos OS Release 12.1X46-D10 and earlier, the session-id-32 in application volume
tracing (AVT) logs were not prefixed with the spu-id, whereas the flow logs were
prefixed with the spu-id.
Starting in Junos OS Release 12.1X46-D10 and later, that functionality has changed.
The AVT logs are now prefixed with the spu-id, so that the session-ids in AVT logs are
consistent with the flow logs and unique across the system.
The following example shows session-id-32 logging before Junos OS Release 12.1X46:
Oct 4 09:13:14 bournville RT_FLOW: RT_FLOW_SESSION_CLOSE: session closed idle

On all high-end SRX Series devices, the attribute type of packets-from-client and
packets-from-server options in the system logs of the following modules have been
changed from unit to string:
•
App Track module— APPTRACK_SESSION_CLOSE, APPTRACK_SESSION_CLOSE_LS,
APPTRACK_SESSION_VOL_UPDATE and APPTRACK_SESSION_VOL_UPDATE_LS
•
Session module—RT_FLOW_SESSION_CLOSE and RT_FLOW_SESSION_CLOSE_LS

Changes in Behavior and Syntax
On all high-end SRX Series devices, the following system log messages have been updated
to include the certificate ID:
•
PKID_PV_KEYPAIR_DEL
Existing message: Key-Pair deletion failed
New message: Key-Pair deletion failed for <cert-id>
•
PKID_PV_CERT_DEL
Existing message: Certificate deletion has occurred
New message: Certificate deletion has occurred for <cert-id>
•
PKID_PV_CERT_LOAD
Existing message: Certificate has been successfully loaded
New message: Certificate <cert-id> has been successfully loaded
•
PKID_PV_KEYPAIR_GEN
Existing message: Key-Pair has been generated
New message: Key-Pair has been generated for <cert-id>
System Management
•
On an SRX5800 device in transparent mode, if the device is not processing multicast
OSPFv3 hello packets, to fix this condition you must remove the “delete security flow
bridge no-packet-flooding” statement from the configuration.
NOTE: Packet flooding is enabled by default. If you have manually disabled
packet flooding with the “set security flow bridge no-packet-flooding”
statement, then use the configuration statement above to revert to the
default behavior, which will allow the device to process multicast OSPFv3
hello packets.
•
During a load override, to enhance the memory for the commit script, make sure you
load the configuration by applying the following commands before commit:
set system scripts commit max-datasize 800000000
set system scripts op max-datasize 800000000
Unified Threat Management (UTM)
•
Starting in Junos OS Release 12.1X46-D20, license control is supported on high-end
SRX Series devices. Licensed features including anti-virus or Enhanced Web Filtering
will not function until a license has been installed. The license must be installed after
installing or upgrading to 12.1X46-D20. Unlicensed features such as UTM blacklists
and whitelists will continue to function without a license.
•
Prior to Junos OS Release 12.1X46-D20, the UTM feature profiles such as antivirus and
Web filtering were provided as a default configuration regardless of the license
requirement.
Copyright © 2016, Juniper Networks, Inc.
137
Junos OS 12.1X46 Release Notes
Starting in Junos OS Release 12.1X46-D20, the default configuration is removed. Use
the set security utm feature-profile anti-virus type <anti-virus-type> and set security utm
feature-profile web-filtering type <web-filtering-type> commands to configure specific
antivirus and Web filter types in UTM feature profiles.
Unified In-Service Software Upgrade (ISSU)
On all high-end SRX Series devices, at the beginning of a chassis cluster unified ISSU,
the system automatically fails over all RG-1+ redundancy groups that are not primary on
the node from which you start the ISSU. This action ensures that the redundancy groups
are all active on only the RG-0 primary node. You no longer need to fail over redundancy
groups manually.
After the system fails over all RG-1+ redundancy groups, the system sets the manual
failover bit and changes all RG-1+ primary node priorities to 255, regardless of whether
the redundancy group failed over to the RG-0 primary node.
Virtual Private Networks (VPNs)
•
For each VPN tunnel, both ESP and AH tunnel sessions are installed on SPUs and the
control plane. In previous Junos OS releases, two tunnel sessions of the same protocol
(ESP or AH) were installed for each VPN tunnel. For branch SRX Series devices, tunnel
sessions are updated with the negotiated protocol after negotiation is completed. For
high-end SRX Series devices, tunnel sessions on anchor SPUs are updated with the
negotiated protocol while non-anchor SPUs retain ESP and AH tunnel sessions.
The ESP and AH tunnel sessions are displayed in the outputs for the show security flow
session and show security flow cp-session operational mode commands.
•
As of Junos OS Release 11.4, checks are performed to validate the IKE ID received from
the VPN peer device. By default, SRX Series and J Series devices validate the IKE ID
received from the peer with the IP address configured for the IKE gateway. In certain
network setups, the IKE ID received from the peer (which can be an IPv4 or IPv6 address,
fully qualified domain name, distinguished name, or e-mail address) does not match
the IKE gateway configured on the SRX Series or J Series device. This can lead to a
Phase 1 validation failure.
To modify the configuration of the SRX Series or J Series device or the peer device for
the IKE ID that is used:
138
•
Starting in Junos OS Release 12.1X46-D10, local-address can be configured at the
[edit security ike gateway gateway-name] hierarchy level to specify the local gateway
address when there are multiple addresses configured on an external physical
interface to a VPN peer. local-address and the remote IKE gateway address must
be in the same address family, either IPv4 or IPv6. Prior to Junos OS Release
12.1X46-D10, local-address was a hidden CLI configuration statement.
•
On the SRX Series or J Series device, configure the remote-identity statement at the
[edit security ike gateway gateway-name] hierarchy level to match the IKE ID that is
received from the peer. Values can be an IPv4 or IPv6 address, fully qualified domain
name, distinguished name, or e-mail address.
Copyright © 2016, Juniper Networks, Inc.
Known Behavior
NOTE: If you do not configure remote-identity, the device uses the IPv4
or IPv6 address that corresponds to the remote peer by default.
•
•
On the peer device, ensure that the IKE ID is the same as the remote-identity
configured on the SRX Series or J Series device. If the peer device is an SRX Series
or J Series device, configure the local-identity statement at the [edit security ike
gateway gateway-name] hierarchy level. Values can be an IPv4 or IPv6 address, fully
qualified domain name, distinguished name, or e-mail address.
On all high-end SRX Series devices, the subject fields of a digital certificate can include
Domain Component (DC), Common Name (CN), Organization Unit (OU), Organization
(O), Location (L), State (ST), and Country (C).
In earlier releases, the show security pki ca-certificate and show security pki
local-certificate CLI operational commands displayed only a single entry for each
subject field, even if the certificate contained multiple entries for a field.
For example, a certificate with two OU fields such as “OU=Shipping Department,
OU=Priority Mail” displayed only the first entry “OU=Shipping Department.” The show
security pki ca-certificate and show security pki local-certificate CLI commands now
display the entire contents of the subject field, including multiple field entries. The
commands also display a new subject string output field that shows the contents of
the subject field as it appears in the certificate.
•
PKI objects include certificates, key pairs, and CRLs. PKI objects are read from the PKI
database when the PKI Daemon starts. The PKI Daemon database loads all certificates
into memory at boot time.
When an object is read into memory from the PKI database, the following new log
message is created:
PKID_PV_OBJECT_READ: A PKI object was read into memory from <location>

Application Layer Gateways (ALGs)
•
On all SRX Series devices, you can define the Sun RPC and MS-RPC mapping entry
ageout value using the set security alg sunrpc map-entry-timeout value and set security
alg msrpc map-entry-timeout value commands. The ageout value ranges from 8 hours
to 72 hours, and the default value is 32 hours.
Copyright © 2016, Juniper Networks, Inc.
139
Junos OS 12.1X46 Release Notes
If either the Sun RPC ALG or the MS-RPC ALG service does not trigger the control
negotiation even after 72 hours, the maximum RPC ALG mapping entry value times
out and the new data connection to the service fails.
•
The maximum size of the jbuf is 9 Kb. If the message buffer size is more than 9 Kb, the
entire message cannot be transferred to the ALG packet handler. This causes
subsequent packets in the session to bypass ALG handling, resulting in a transaction
failure.
The limitations for SCCP ALGs are as follows:
•
The SCCP is a Cisco proprietary protocol. So, any changes to the protocol by Cisco
cause the SCCP ALG implementation to break. However, workarounds are provided
to bypass strict decoding and allow any protocol changes to be handled gracefully.
•
The SCCP ALG validates protocol data units (PDUs) with message IDs in the ranges
[0x0 - 0x12], [0x20 - 0x49], and [0x81 - 0x14A]. By default, all other message IDs are
treated as unknown messages and are dropped by the SCCP ALG.
•
Any changes to the policies will drop the sessions and impact already established
SCCP calls.
•
The SCCP ALG opens pinholes that are collapsed during traffic or media inactivity. This
means that during a temporary loss of connectivity, media sessions are not
re-established.
•
CallManager (CM) version 6.x and later does not support TCP probe packets in chassis
cluster mode. As a result, the existing SCCP sessions will break when there is a failover.
You can still create new SCCP sessions during failover.
The PPTP ALG with IPv6 support has the following limitation:
•
Because PPP packets are compressed with Microsoft Point-to-Point Encryption (MPPE)
protocol after the tunnel is set up, translation of the IP header in the PPP package
cannot be handled; therefore, to make sure PPTP connection works well, the PPTP
client must be able to work in dual stack mode. So that an IPv6 PPTP client can accept
an IPv4 address for PPP tunnel interface, by which it can communicate with the IPv4
PPTP server without IP address translation for PPP packets.
The RTSP ALG with IPv6 support has the following limitations:
140
•
Real-Time Streaming Protocol (RTSP) is an Application Layer protocol for controlling
the delivery of data with real-time properties. The RTSP ALG supports a peer client,
and the server transmits real-time media; it does not support third-party endpoints
involved in the transaction.
•
In case of destination NAT or NAT64 for IP address translation, if the RTSP message
(including the Session Description Protocol (SDP) application content) length exceeds
2500 bytes, then the RTSP ALG processes only the first 2500 bytes of the message
and ignores the rest of the message. In this scenario, the IP address in the RTSP message
is not translated if the IP address does not appear in the first 2500 bytes.
Copyright © 2016, Juniper Networks, Inc.
Known Behavior
The SIP ALG with IPv6 support has the following limitation:
•
When NAT64 with persistent NAT is implemented, the SIP ALG adds the NAT translation
to the persistent NAT binding table if NAT is configured on the Address of Record
(AOR). Because persistent NAT cannot duplicate the address configured, coexistence
of NAT66 and NAT64 configured on the same address is not supported.
Only one binding is created for the same source IP address.
AppSecure
•
J-Web pages for AppSecure are preliminary.
•
Custom application signatures and custom nested application signatures are not
currently supported by J-Web.
•
When ALG is enabled, application identification includes the ALG result to identify the
application of the control sessions. Application firewall permits ALG data sessions
whenever control sessions are permitted. If the control session is denied, there are no
data sessions.
When ALG is disabled, application identification relies on its signatures to identify the
application of the control and data sessions. If a signature match is not found, the
application is considered unknown. Application firewall handles applications based
on the application identification result.
Chassis Cluster
•
If you are adding next-generation SRX5K-SPC-4-15-320 SPCs on SRX5600 and
SRX5800 devices that are part of a chassis cluster, you must install the new SPCs so
that a next-generation SRX5K-SPC-4-15-320 SPC is the SPC in the original
lowest-numbered slot. For example, if the chassis already has two first-generation
SRX5K-SPC-2-10-40 SPCs installed in slots 2 and 3, you cannot install
SRX5K-SPC-4-15-320 SPCs in slot 0 or 1. You will need to make sure that an
SRX5K-SPC-4-15-320 SPC is installed in the slot that provides central point
functionality (in this case, slot 2). This ensures that the central point functionality is
performed by an SRX5K-SPC-4-15-320 SPC.
•
On all high-end SRX Series devices, IPsec VPN is not supported in active/active chassis
cluster configuration (that is, when there are multiple RG1+ redundancy groups).
The following list describes the limitations for inserting an SPC on SRX1400, SRX3400,
SRX3600, SRX5600, and SRX5800 devices in chassis cluster mode:
•
The chassis cluster must be in active/passive mode before and during the SPC insert
procedure.
•
A different number of SPCs cannot be inserted in two different nodes.
•
A new SPC must be inserted in a slot that is higher than the central point slot.
NOTE: The existing combo central point cannot be changed to a full central
point after the new SPC is inserted.
Copyright © 2016, Juniper Networks, Inc.
141
Junos OS 12.1X46 Release Notes
•
During an SPC insert procedure, the IKE and IPsec configurations cannot be modified.
•
Users cannot specify the SPU and the IKE instance to anchor a tunnel.
•
After a new SPC is inserted, the existing tunnels cannot use the processing power of
the new SPC and redistribute it to the new SPC.
•
Dynamic tunnels cannot load-balance across different SPCs.
•
The manual VPN name and the site-to-site gateway name cannot be the same.
•
In a chassis cluster scaling environment, the heartbeat-threshold must always be set
to 8.
•
An APN or an IMSI filter must be limited to 600 for each GTP profile. The number of
filters is directly proportional to the number of IMSI prefix entries. For example, if one
APN is configured with two IMSI prefix entries, then the number of filters is two.
•
Eight QoS queues are supported per ae interface.
•
The first recommended unified ISSU from release is Junos OS Release 10.4R4. If you
intend to upgrade from a release earlier than Junos OS Release 10.4R4, see the release
notes for the release that you are upgrading from for information about limitations and
issues related to upgrading.
•
Unified ISSU does not support UTM.
•
For the latest unified ISSU support status, go to the Juniper Networks Knowledge Base
(KB): http://kb.juniper.net/ and search for KB17946.
•
Unified ISSU does not support version downgrading.
•
In large chassis cluster configurations on SRX1400, SRX3400 or SRX3600 devices,
you need to increase the wait time before triggering failover. In a full-capacity
implementation, we recommend increasing the wait to 8 seconds by modifying
heartbeat-threshold and heartbeat-interval values in the [edit chassis cluster] hierarchy.
The product of the heartbeat-threshold and heartbeat-interval values defines the time
before failover. The default values (heartbeat-threshold of 3 beats and
heartbeat-interval of 1000 milliseconds) produce a wait time of 3 seconds.
To change the wait time, modify the option values so that the product equals the
desired setting. For example, setting the heartbeat-threshold to 8 and maintaining the
default value for the heartbeat-interval (1000 milliseconds) yields a wait time of
8 seconds. Likewise, setting the heartbeat-threshold to 4 and the heartbeat-interval to
2000 milliseconds also yields a wait time of 8 seconds.

•
Packet-based forwarding for MPLS and ISO protocol families is not supported.
•
On SRX5600 and SRX5800 devices, only two of the 10 ports on each PIC of 40-port
1-Gigabit Ethernet I/O cards (IOCs) can simultaneously enable IP address monitoring.
Because there are four PICs per IOC, this permits a total of eight ports per IOC to be
monitored. If more than two ports per PIC on 40-port 1-Gigabit Ethernet IOCs are
configured for IP address monitoring, the commit will succeed but a log entry will be
generated, and the accuracy and stability of IP address monitoring cannot be ensured.
This limitation does not apply to any other IOCs or devices.

Known Behavior
•
IP address monitoring is not supported on reth interface link aggregation groups (LAGs)
or on child interfaces of reth interface LAGs.
•
Screen statistics data can be gathered on the primary device only.
•
Only reth interfaces are supported for IKE external interface configuration in IPsec VPN.
Other interface types can be configured, but IPsec VPN might not work.
Dynamic Host Configuration Protocol (DHCP)
•
On all high-end SRX Series devices, DHCPv6 client authentication is not supported.
•
On all high-end SRX Series devices, DHCP client and server functionality is not supported
in a chassis cluster.
•
On all high-end SRX Series devices, DHCP relay is unable to update the binding status
based on DHCP_RENEW and DHCP_RELEASE messages.
Flow and Processing
•
On all high-end SRX Series devices, when packet-logging functionality is configured
with an improved pre-attack configuration parameter value, the resource usage
increases proportionally and might affect the performance.
•
On all high-end SRX Series devices, the default authentication table capacity is 45,000;
the administrator can increase the capacity to a maximum of 50,000.
On SRX1400 devices, the default authentication table capacity is 10,000; the
administrator can increase the capacity to a maximum of 15,000.
•
On all high-end SRX Series devices, when devices are operating in flow mode, the
Routing Engine side cannot detect the path MTU of an IPv6 multicast address (with
a large size packet).
•
On all high-end SRX Series devices, you cannot configure route policies and route
patterns in the same dial plan.
•
On all high-end SRX Series devices, high CPU utilization triggered for reasons such as
CPU intensive commands and SNMP walks causes the BFD protocol to flap while
processing large BGP updates.
•
On all high-end SRX Series devices, downgrading is not supported in low-impact unified
ISSU chassis cluster upgrades (LICU).
•
On SRX5800 devices, network processing bundling is not supported in Layer 2
transparent mode.

Junos OS 12.1X46 Release Notes
General Packet Radio Service (GPRS)
The following Gateway GPRS Support Node (GGSN) and Packet Data Network Gateway
(PGW) limitations are applicable for all high-end SRX Series devices.
•
GGSN and PGW traffic must pass through the GPRS tunneling protocol (GTP)
framework; otherwise, the tunnel status is updated incorrectly.
•
The central point distributes all GTP packets to SPUs according to upstream endpoints
for GGSN or PGW (one GGSN or PGW is the upstream endpoint of the GTP tunnels).
Information is checked on the upstream endpoint IP and GTP packets in the GGSN
pool network in the following way:
•
If the upstream endpoint source IP address in the Create-PDP-Context-Response
or Create-Session-Response message is different from the IP address of the upstream
endpoint, tunnels are created on one SPU. According to the IP address of the
upstream endpoint for GGSN or PGW, an incoming GTP tunnel message is moved
to a second SPU, and the GTP packets are dropped because no tunnel is found.
NOTE: In the GGSN pool scenario, GGSN can reply with a
Create-PDP-Context-Response or Create-Session-Response message
using a different source IP address than the one where the request was
sent to. Therefore the request and the response can run on two different
flow sessions, and these two flow sessions can be distributed to different
SPUs.
The following GTP firewall limitations are applicable on all high-end SRX Series devices.
•
GTP firewall does not support hot-insertable and hot-removable hardware.
•
The GTP firewall needs to learn the network’s GSN table and install the table for the
central point and the SPU. Otherwise, some GTP traffic is blocked when the firewall
is inserted in the network.
•
On all high-end SRX Series devices, the GPRS tunneling protocol (GTP) module
competes with other modules for memory allocation during runtime because it has
dynamic memory allocation for tunnel management.
•
On all high-end SRX Series devices, GTP-U inspection has the following limitations:
•
When GTP-U inspection is enabled, GTP-U throughput drops.
•
GTP-U inspection only affects the new flow sessions that are created after enabling
the GTP-U inspection.
NOTE: When GTP-U inspection is disabled, the GTP module ignores the
traffic on which the corresponding flow sessions were created. When
GTP-U inspection is reenabled, the GTP module continues to ignore the
traffic during the lifetime of the flow sessions that were created before
the GTP-U inspection was reenabled.
144
Copyright © 2016, Juniper Networks, Inc.
Known Behavior
•
•
The ramp-up rate of GTP tunnel management messages decreases slightly (the
decrease rate is less than 10 percent) when the GTP control (GTP-C) tunnel and
GTP-U tunnel are created on different SPUs, whether GTP-U inspection is enabled
or not.
On all high-end SRX Series devices, NAT for GTP packets has the following limitations:
•
Only static NAT is supported; port NAT is not supported.
•
During a packet data protocol (PDP) context negotiation and update, the packet
sent from the customer’s GSNs must carry the public IP in the GTP payload.
•
Source IP and destination IP addresses cannot be translated simultaneously for a
packet.
•
NAT for GTP only works in default logical systems.
•
IPv6 is not supported.
The following SCTP limitations are applicable on all high-end SRX Series devices:
•
Dynamic policy is not supported for SCTP. You must configure all policies for needed
SCTP sessions.
•
SCTP modules only inspect IPv4 traffic. IPv6 traffic will be passed or dropped by
flow-based or policy-based processing directly, and no SCTP module inspection will
occur.
•
Only the first chunk in each SCTP packet is checked.
•
For static NAT to work, the interfaces packets (from one side: client or server side)
coming in must belong to the same zone.
•
For multihome cases, only IPv4 Address Parameter (5) in INIT or INI-ACK is supported.
•
Only static NAT is supported for SCTP.
•
SCTP enable or disable is controlled by whether there is a SCTP profile configured.
When you disable the SCTP feature, all associations are deleted and later SCTP packets
will pass or drop according to the policy.
If you want to enable SCTP again, all the running SCTP communications will be dropped,
because no associations exist. New SCTP communications can establish an association
and perform the inspections.
Clear old SCTP sessions when SCTP is reenabled; doing this will avoid any impact
caused by the old SCTP sessions on the new SCTP communications.
•
Only established SCTP associations will be synchronized to peer node.
•
A maximum of eight source IP addresses and eight destination IP addresses are allowed
in an SCTP communication.
•
One SPU supports a maximum of 5000 associations and a maximum of 320, 000
SCTP sessions.
•
The 4-way handshake process should be done in one node of a cluster. If the SCTP
4-way handshake process is handled on two nodes (for example, two sessions on two
Copyright © 2016, Juniper Networks, Inc.
145
Junos OS 12.1X46 Release Notes
nodes in active/active mode) or the cluster fails over before the 4-way handshake is
finished, the association cannot be established successfully.
•
If you configure different policies for each session belonging to one association, there
will be multiple policies related to one association. The SCTP packet management
(drop, rate limit, and so on) will use the profile attached to the handling SCTP session's
policy.
The association's timeout will only use the profile attached to its INIT packet’s policy.
If the INIT packet’s policy changes the attached profile, the old profile is deleted, and
the association will refresh the timeout configuration. However, if the INIT packet’s
policy changes its attached profile without deleting the old profile, the association will
not refresh the timeout configuration.
•
In some cases, the associations might not be distributed to SPUs very evenly because
the port’s hash result on the central point is uneven. For example, this event can occur
when only two peers of ports are used, and one peer has 100 associations, but another
peer has only one association. In this case, the associations cannot be distributed
evenly on the firewall with more than one SPU.
•
SCTP sessions will not be deleted with associations, and the sessions will time out in
30 minutes, which is the default value. If you need the session to time out soon, you
can preconfigure the SCTP application timeout value.
•
M3UA or SCCP message parsing is checked , but the M3UA or SCCP stateful inspection
is not checked.
•
Only ITU-T Rec. Q.711-Q.714 (07 or 96) standard is supported. ANSI, ETSI, China, and
other standards are not supported.
•
Only RFC 4960 is supported.
On all high-end SRX Series devices, SCTP payload protocol blocking has the following
limitations:
•
The supported protocol decimal value is from 0 to 63. This value includes 48 IANA
assigned protocols and 16 unassigned protocols.
•
When running SCTP data traffic during a unified ISSU, the SCTP data packets are
dropped at Junos OS Release 12.1X46. Only after the unified ISSU is finished, you can
configure permit on Junos OS Release 12.1X46-D10 and pass the SCTP data traffic.
•
Only the first data chunk is inspected, so protocol blocking only works for the first data
chunk.
On all high-end SRX Series devices, the SCTP rate limiting function has the following
limitations:
146
•
The supported protocol decimal value is from 0 to 63. This value includes 48 IANA
assigned protocols and 16 unassigned protocols.
•
Only the first data chunk is inspected, so the rate limiting function only works for the
first data chunk.
•
A maximum of 80 addresses are rate limited in one profile.
Copyright © 2016, Juniper Networks, Inc.
Known Behavior
•
A maximum of 10 protocols are rate limited for one address in one profile.
•
The supported rate limit value is from 1 to 12000.
Hardware
•
SRX5800 devices does not support a redundant SCB card (third SCB) if an SRX5k
SPC II (FRU model number: SRX5K-SPC-4-15-320) is installed on the device. If you
have installed an SRX5k SPC II on an SRX5800 device with a redundant SCB card,
make sure to remove the redundant SCB card.
Interfaces and Routing
This section covers filter and policing limitations.
•
On SRX1400, SRX3400, and SRX3600 devices, the following feature is not supported
by a simple filter:
•
Forwarding class as match condition
•
On all high-end SRX Series devices, PIM does not support upstream and downstream
interfaces across different virtual routers in flow mode
•
On SRX1400, SRX3400 and SRX3600, devices, the following features are not supported
by a policer or a three-color-policer:
•
•
•
Color-aware mode of a three-color-policer
•
Filter-specific policer
•
Forwarding class as action of a policer
•
Logical interface policer
•
Logical interface three-color policer

Packet loss priority as action of a three-color-policer
On all high-end SRX Series devices, the following features are not supported by a
firewall filter:
•
Egress filter-based forwarding (FBF)
•
Forwarding table filter (FTF)
SRX3400 and SRX3600 devices have the following limitations of a simple filter:
•
The forwarding class is the match condition.
•
In the packet processor on an IOC, up to 400 logical interfaces can be applied with
simple filters.
•
In the packet processor on an IOC, the maximum number of terms of all simple filters
is 2000.

In the packet processor on an IOC, the maximum number of policers is 2000.
•
In the packet processor on an IOC, the maximum number of three-color-policers is
2000.
•
The maximum burst size of a policer or three-color-policer is 16 MB.
On all high-end SRX Series devices, the flow monitoring version 9 has the following
limitations:
•
Routing Engine based flow monitoring V5 or V8 mode is mutually exclusive with
inline flow monitoring V9.
•
High-end SRX Series devices do not support multiple collectors like branch SRX
Series devices. Only one V9 collector per IPv4 or IPv6 is supported.
•
Flow aggregation for V9 export is not supported.
•
Only UDP over IPv4 or IPv6 protocol can be used as the transport protocol.
•
Only the standard IPv4 or IPv6 template is supported for exporting flow monitoring
records.
•
User-defined or special templates are not supported for exporting flow monitoring
records.
•
Chassis cluster is supported without flow monitoring session synchronization.
•
On SRX3400 and SRX3600 devices, when you enable the monitor traffic option using
the monitor traffic command to monitor the FXP interface traffic, interface bounce
occurs. You must use the monitor traffic interface fxp0 no-promiscuous command to
avoid the issue.
•
On all high-end SRX Series devices, the lo0 logical interface cannot be configured with
RG0 if used as an IKE gateway external interface.
•
On all high-end SRX Series devices, the set protocols bgp family inet flow and set
routing-options flow CLI statements are no longer available, because BGP flow spec
functionality is not supported on these devices.
•
On all high-end SRX Series devices, the LACP is not supported on Layer 2 interfaces.
•
On all high-end SRX Series devices, BGP-based virtual private LAN service (VPLS)
works on child ports and physical interfaces, but not over ae interfaces.
•
When using SRX Series devices in chassis cluster mode, we recommend that you do
not configure any local interfaces (or combination of local interfaces) along with
redundant Ethernet interfaces.
For example:
The following configuration of chassis cluster redundant Ethernet interfaces, in which
interfaces are configured as local interfaces, is not recommended:
ge-2/0/2 {
unit 0 {
family inet {
address 1.1.1.1/24;
}
148

}
The following configuration of chassis cluster redundant Ethernet interfaces, in which
interfaces are configured as part of redundant Ethernet interfaces, is recommended:
interfaces {
ge-2/0/2 {
gigether-options {
redundant-parent reth2;
}
}
reth2 {
redundant-ether-options {
redundancy-group 1;
}
unit 0 {
family inet {
address 1.1.1.1/24;
}
}
}
}
Intrusion Detection and Prevention (IDP)
•
On all high-end SRX Series devices, from Junos OS Release 11.2 and later, the IDP
security package is based on the Berkeley database. Hence, when the Junos OS image
is upgraded from Junos OS Release 11.1 or earlier to Junos OS Release 11.2 or later, a
migration of IDP security package files needs to be performed. This is done
automatically on upgrade when the IDP process comes up. Similarly, when the image
is downgraded, a migration (secDb install) is automatically performed when the IDP
process comes up, and previously installed database files are deleted.
However, migration is dependent on the XML files for the installed database present
on the device. For first-time installation, completely updated XML files are required. If
the last update on the device was an incremental update, migration might fail. In such
a case, you have to manually download and install the IDP security package using the
download or install CLI commands before using the IDP configuration with predefined
attacks or groups.
As a workaround, use the following CLI commands to manually download the individual
components of the security package from the Juniper Security Engineering portal and
install the full update:
•
•
request security idp security-package download full-update
•
request security idp security-package install
On all high-end SRX Series devices, the IDP policies for each user logical system are
compiled together and stored on the data plane memory. To estimate adequate data
plane memory for a configuration, consider these two factors:
Copyright © 2016, Juniper Networks, Inc.
149
Junos OS 12.1X46 Release Notes
•
IDP policies applied to each user logical system are considered unique instances
because the ID and zones for each user logical system are different. Estimates need
to consider the combined memory requirements for all user logical systems.
•
As the application database increases, compiled policies requires more memory.
Memory usage should be kept below the available data plane memory to allow for
database increases.
•
On all high-end SRX Series devices, ingress as ge-0/0/2 and egress as ge-0/0/2.100
works with flow showing both source and destination interface as ge-0/0/2.100.
•
IDP does not allow header checks for nonpacket contexts.
•
On all high-end SRX Series devices, application-level distributed denial-of-service
(application-level DDoS) detection does not work if two rules with different
application-level DDoS applications process traffic going to a single destination
application server. When setting up application-level DDoS rules, make sure that you
do not configure rulebase-ddos rules that have two different application-ddos objects
when the traffic destined to one application server can process more than one rule.
Essentially, for each protected application server, you have to configure the
application-level DDoS rules so that traffic destined for one protected server processes
only one application-level DDoS rule.
NOTE: Application-level DDoS rules are terminal, which means that once
traffic is processed by one rule, it will not be processed by other rules.
The following configuration options can be committed, but they will not work properly:
•
source-zone
destination-zone
destination-ip
service
application-ddos
Application

1.1.1.1:80
source-zone-2
dst-1
any
http
http-appddos2
1.1.1.1:80
On all high-end SRX Series devices, application-level DDoS rule base (rulebase-ddos)
does not support port mapping. If you configure an application other than default, and
if the application is from either predefined Junos OS applications or a custom application
that maps an application service to a nonstandard port, application-level DDoS
detection will not work.
When you configure the application setting as default, IDP uses application identification
to detect applications running on standard and nonstandard ports; thus, the
application-level DDoS detection would work properly.
•
150
On all high-end SRX Series devices, all IDP policy templates are supported except All
Attacks. There is a 100-MB policy size limit for integrated mode and a 150-MB policy
size limit for dedicated mode. The current IDP policy templates supported are dynamic,
based on the attack signatures being added. Therefore, be aware that supported
templates might eventually grow past the policy size limit.

•
DNS_Service
•
File_Server
•
Getting_Started
•
IDP_Default
•
Recommended
•
Web_Server
IDP deployed in both active/active and active/passive chassis clusters has the following
limitations:
•
No inspection of sessions that fail over or fail back.
•
The IP action table is not synchronized across nodes.
•
The Routing Engine on the secondary node might not be able to reach networks that
are reachable only through a Packet Forwarding Engine.
•
The SSL session ID cache is not synchronized across nodes. If an SSL session reuses
a session ID and it happens to be processed on a node other than the one on which
the session ID is cached, the SSL session cannot be decrypted and will be bypassed
for IDP inspection.
IDP deployed in active/active chassis clusters has a limitation that for time-binding
scope source traffic, if attacks from a source (with more than one destination) have
active sessions distributed across nodes, then the attack might not be detected because
time-binding counting has a local-node-only view. Detecting this sort of attack requires
an RTO synchronization of the time-binding state that is not currently supported.
IP Monitoring
•
When IP monitoring is enabled on a different subnet than the reth IP address, then you
must configure the proxy-arp unrestricted option on the upstream router.
IPv6
•
Devices with IPv6 addressing do not perform fragmentation. IPv6 hosts should either
perform path MTU discovery or send packets smaller than the IPv6 minimum MTU
size of 1280 bytes.
•
Because IPv6 addresses are 128 bits long compared to IPv4 addresses, which are
32-bits long, IPv6 IPsec packet processing requires more resources. Therefore, a small
performance degradation is observed.
•
IPv6 uses more memory to set up the IPsec tunnel. Therefore, the IPsec IPv4 tunnel
scalability numbers might drop.
Copyright © 2016, Juniper Networks, Inc.
151
Junos OS 12.1X46 Release Notes
•
The addition of IPv6 capability might cause a drop in the IPsec IPv4-in-IPv4 tunnel
throughput performance.

regarding NSM support for IPv6 addressing on all high-end SRX Series devices.
•
Security policy—Only IDP for IPv6 sessions is supported for all high-end SRX Series
devices. UTM for IPv6 sessions is not supported. If your current security policy uses
rules with the IP address wildcard any, and UTM features are enabled, you will encounter
configuration commit errors because UTM features do not yet support IPv6 addresses.
To resolve the errors, modify the rule returning the error so that the any-ipv4 wildcard
is used; and create separate rules for IPv6 traffic that do not include UTM features.

On all high-end SRX Series devices, users cannot differentiate between Active and
Inactive configurations on the System Identity, Management Access, User Management,

Layer 2 Features
•
Layer 2 Bridging and Transparent Mode— On all high-end SRX Series devices, bridging
and transparent mode are not supported on Mini-Physical Interface Modules
(Mini-PIMs).
Logical Systems
•
The master logical system must not be bound to a security profile that is configured
with a 0 percent reserved CPU quota because traffic loss could occur. When upgrading
all high-end SRX Series devices from Junos OS Release 11.2, make sure that the reserved
CPU quota in the security profile that is bound to the master logical system is configured
for 1 percent or more. After upgrading from Junos OS Release 11.2, the reserved CPU
quota is added to the default security profile with a value of 1 percent.
•
On all high-end SRX Series devices, quality-of-service (QoS) classification across
interconnected logical systems does not work.
•
On all high-end SRX Series devices, the number of logical system security profiles you
can create is constrained by an internal limit on security profile IDs. The security profile
ID range is from 1 through 32, with ID 0 reserved for the internally configured default
security profile. When the maximum number of security profiles is reached, if you want
to add a new security profile, you must first delete one or more existing security profiles,
commit the configuration, and then create the new security profile and commit it. You
cannot add a new security profile and remove an existing one within a single
configuration commit.
If you want to add more than one new security profile, the same rule is true. You must
first delete the equivalent number of existing security profiles, commit the configuration,
and then create the new security profiles and commit them.
•
User and administrator configuration for logical systems—Configuration for users
for all logical systems and all user logical systems administrators must be done at the
Copyright © 2016, Juniper Networks, Inc.
153
Junos OS 12.1X46 Release Notes
root level by the master administrator. A user logical system administrator cannot
create other user logical system administrators or user accounts for their logical
systems.
•
Name-space separation—The same name cannot be used in two logical systems. For
example, if logical-system1 includes the username “Bob” then other logical systems
on the device cannot include the username “Bob”.
•
Commit rollback—Commit rollback is supported at the root level only.
•
Trace and debug—Trace and debug are supported at the root level only.
•
Class of service—You cannot configure class of service on logical tunnel (lt-0/0/0)
interfaces.
•
ALGs—The master administrator can configure ALGs at the root level. The configuration
is inherited by all user logical systems. It cannot be configured discretely for user logical
systems.
Network Address Translation (NAT)
•
Single IP address in a source NAT pool without PAT—The number of hosts that a
source NAT pool without PAT can support is limited to the number of addresses in the
pool. When you have a pool with a single IP address, only one host can be supported,
and traffic from other hosts is blocked because there are no resources available.
If a single IP address is configured for a source NAT pool without PAT when NAT
resource assignment is not in active-backup mode in a chassis cluster, traffic through
node 1 will be blocked.
•
For all ALG traffic, except FTP, we recommend that you not use the static NAT rule
options source-address or source-port. Data session creation can fail if these options
are used, because the IP address and the source port value, which is a random value,
might not match the static NAT rule. For the same reason, we also recommend that
you not use the source NAT rule option source-port for ALG traffic.
For FTP ALG traffic, the source-address option can be used because an IP address can
be provided to match the source address of a static NAT rule.
Additionally, because static NAT rules do not support overlapping addresses and ports,
they should not be used to map one external IP address to multiple internal IP addresses
for ALG traffic. For example, if different sites want to access two different FTP servers,
the internal FTP servers should be mapped to two different external IP addresses.
•
On all high-end SRX Series devices, in case of SSL proxy, sessions are whitelisted based
on the actual IP address and not on the translated IP address. Because of this, in the
whitelist configuration of the SSL proxy profile, the actual IP address should be provided
and not the translated IP addresses.
Example:
Consider a destination NAT rule that translates destination IP address 20.20.20.20 to
5.0.0.1 using the following commands:
•
154
set security nat destination pool d1 address 5.0.0.1/32

In the above scenario, to exempt a session from SSL proxy inspection, the following
IP address should be added to the whitelist:

Address Capacity
Increasing the capacity of source NAT pools consumes memory needed for port
allocation. When source NAT pool and IP address limits are reached, port ranges should
be reassigned. That is, the number of ports for each IP address should be decreased
when the number of IP addresses and source NAT pools is increased. This ensures NAT
does not consume too much memory. Use the port-range statement in configuration
mode in the CLI to assign a new port range or the pool-default-port-range statement
to override the specified default.
Configuring port overloading should also be done carefully when source NAT pools
are increased.
For source pool with PAT in range (63,488 through 65,535), two ports are allocated
at one time for RTP or RTCP applications, such as SIP, H.323, and RTSP. In these
scenarios, each IP address supports PAT, occupying 2048 ports (63,488 through
65,535) for ALG module use. On SRX5600 and SRX5800 devices, if all of the 12288
source pool is configured, a port allocation of 2M is reserved for twin port use.
•
NAT rule capacity change—To support the use of large-scale NAT at the edge of the
carrier network, the device wide NAT rule capacity has been changed.
The number of destination, static, and source NAT rules has been incremented as
shown in Table 16 on page 156. The limitation on the number of destination rule sets
and static rule sets has been increased.
Table 16 on page 156 provides the requirements per device to increase the configuration
limitation as well as to scale the capacity for each device.

The restriction on the number of rules per rule set has been increased so that there is
only a devicewide limitation on how many rules a device can support. This restriction
is provided to help you better plan and configure the NAT rules for the device.
For memory consumption, there is no guarantee to support these numbers (maximum
source rule or rule set + maximum destination rule or rule set + maximum static rule
or rule-set) at the same time for SRX1400, SRX3400, SRX3600, SRX5600, and
SRX5800 devices.

Security Policies
•
156
On all high-end SRX Series devices, the current SSL proxy implementation has the
following connectivity limitations:
•
The SSLv2 protocol is not supported. SSL sessions using SSLv2 are dropped.
•
SSL sessions where client certificate authentication is mandatory are dropped.
•
SSL sessions where renegotiation is requested are dropped.
•
On all high-end SRX Series devices, for a particular session, the SSL proxy is only
enabled if a relevant feature related to SSL traffic is also enabled. Features that are
related to SSL traffic are IDP, application identification, application firewall, and
application tracking. If none of the above listed features are active on a session, the
SSL proxy bypasses the session and logs are not generated in this scenario.
•
On all high-end SRX Series devices, you cannot configure the following IP addresses
as negated addresses in a policy:
•
Wildcard addresses
•
IPv6 addresses
Copyright © 2016, Juniper Networks, Inc.
Known Behavior
•
Addresses such as any, any-ipv4 , any-IPv6 and 0.0.0.0
•
When a range of addresses or a single address is negated, it can be divided into multiple
addresses. These negated addresses are shown as a prefix or a length that requires
more memory for storage on a Packet Forwarding Engine.
•
Each platform has a limited number of policies with negated addresses. A policy can
contain 10 source or destination addresses. The capacity of the policy depends on the
maximum number of policies that the platform supports.
Services Offloading
•
Services offloading has the following limitations:
•
Transparent mode is not supported. If transparent mode is configured, a normal
session is installed.
•
LAG is not supported. If a LAG is configured, a normal session is installed.
•
Only multicast sessions with one fan-out are supported. If a multicast session with
more than one fan-out exists, a normal session is installed.
•
Only active/passive chassis cluster configuration is supported. Active/active chassis
cluster configuration is not supported.
•
Fragmented packets are not supported. If fragmented packets exist, a normal session
is installed.
•
IPv6 is not supported. If IPv6 is configured, a normal session is installed.
NOTE: A normal session forwards packets from the network processor to
the SPU for fast-path processing. A services-offload session processes
fast-path packets in the network processor and the packets exit out of the
network processor itself.
•
For Non-Services-Offload Sessions:
•
When services offloading is enabled, for normal sessions, the performance can drop
by approximately 20 percent for connections per second (CPS) and 15 percent for
packets per second (pps) when compared with non-services-offload mode.
•
For Services-Offload Sessions:
When services offloading is enabled, for fast-forward sessions, the performance can
drop by approximately 13 percent for connections per second (CPS).

Junos OS 12.1X46 Release Notes
Simple Network Management Protocol (SNMP)
•
On all high-end SRX Series devices, the show snmp mib CLI command will not display
the output for security related MIBs. We recommend that you use an SNMP client and
prefix logical-system-name@ to the community name. For example, if the community
is public, use default@public for default root logical system.
Unified Access Control
•
During SRX device communication to the Infranet Controller (IC), the connection
remains in attempt-next state preventing a successful communication. This happens
when an outgoing interface used to connect the IC is a part of routing-instance.
Unified Threat Management (UTM)
•
On SRX5400 devices configured with Sophos Antivirus, certain files whose sizes are
larger than the max-content-size might not go into fallback unlike other AV engines
and instead end up being detected as clean file for few protocols which does not
pre-declare the content size.
Virtual Private Networks (VPNs)
On all high-end SRX Series devices, IKEv2 does not include support for:
158
•
Policy-based tunnels
•
Dial-up tunnels
•
VPN monitoring
•
NHTP for st0—Reusing the same tunnel interface for multiple tunnels
•
EAP
•
Multiple child SAs for the same traffic selectors for each QoS value
•
Proposal enhancement features
•
Reuse of Diffie-Hellman (DH) exponentials
•
IP Payload Compression Protocol (IPComp)
•
On all high-end SRX Series devices, configuring XAuth with AutoVPN secure tunnel
(st0) interfaces in point-to-multipoint mode and dynamic IKE gateways is not
supported.
•
VPN monitoring and Suite B cryptographic configuration options ecdsa-signatures-384
(for IKE authentication) and Diffie-Hellman group20 consume considerable CPU
resources. If VPN monitoring and the ecdsa-signatures-384 and group20 options are
used on an SRX Series device with a large number of tunnels configured, the device
must have the next-generation SPC installed.
•
On all high-end SRX Series devices, for auto VPN, the tunnel setup rate decreases with
an increase in the number of SPCs in the device.

Documentation
•
On SRX Series devices, configuring RIP demand circuits over VPN interfaces is not
supported.
•
On a high-end SRX Series device, VPN monitoring of an externally connected device
(such as a PC) is not supported. The destination IP address for VPN monitoring must
be a local interface on the high-end SRX Series device.
•
IPv6 policy-based VPN is not supported
•
On all high-end SRX Series devices, DH-group 14 is not supported for dynamic VPN.
•
On all high-end SRX Series devices, when you enable VPN, overlapping of the IP
addresses across virtual routers is supported with the following limitations:
•
An IKE external interface address cannot overlap with any other virtual router.
•
An internal or trust interface address can overlap across any other virtual router.
•
An st0 interface address cannot overlap in route-based VPN in point-to-multipoint
tunnels such as NHTB.
•
An st0 interface address can overlap in route-based VPN in point-to-point tunnels.
•
On all high-end SRX Series devices, the DF-bit configuration for VPN only works if the
original packet size is smaller than the st0 interface MTU, and larger than the external
interface-ipsec overhead.
•
RIP is not supported in point-to-multipoint (P2MP) VPN scenarios including AutoVPN
deployments. We recommend OSPF or IBGP for dynamic routing when using P2MP
VPN tunnels.
•
On all high-end SRX Series devices, the IPsec NAT-T tunnel scaling and sustaining
issues are as follows:
•
For a given private IP address, the NAT device should translate both 500 and 4500
private ports to the same public IP address.
•
The total number of tunnels from a given public translated IP cannot exceed 1000
tunnels.
•
On all high-end SRX Series devices, for auto VPN, the tunnel setup rate decreases with
an increase in the number of SPCs in the device.

Application Layer Gateways (ALGs)
•
On all SRX Series devices, the RSH ALG does not inspect the legality of the control
message, hence the malformed messages are bypassed. On Junos OS Releases
containing the fix, the RSH ALG is changed to disable by default. PR1093558
Logical Systems
•
On all high-end SRX Series devices, predefined application sets can only be invokedthe
root logical system; they cannot be invoked in the custom logical system.
As a workaround, define the application sets manually for the custom logical system
instead of using the predefined application sets. PR1075409

Chassis Cluster
•
On SRX1400, SRX3400, or SRX3600 chassis cluster, if the chassis cluster fabric ports
are connected through a switch, some random packets might come into the chassis
cluster fabric ports. These packets are interpreted as chassis cluster packets (such as
real-time objects) and are forwarded to an invalid SPU. For example, the packets are
forwarded to a SPU that does not exist (depending on the interpretation of the invalid
packets). The invalid chassis cluster packets cannot be forwarded to the invalid SPU.
Hence, the packets will be queued on a certain network processor. When the network
processor is full, all data traffic will be blocked on the ports associated with that network
processor. PR1042676
Flow-Based and Packet-Based Processing
•
On all high-end SRX Series devices, when the number of AS paths is more than
400,000, the J-Flow configuration will not be bound to the FPC/PIC, which causes
J-Flow to stop working. PR1089141
•
On all high-end SRX Series devices working in transparent mode, the OSPFv3 packets
are dropped when they pass through the device and are inspected by deep packet
inspection (DPI). PR1094093
•
On all high-end SRX Series devices, if Services Offloading is enabled, in certain cases,
such as packets flowing on an LAG interface or fragmented packets processing,
duplicated packets might be randomly generated and forwarded out of the device.

Application Identification
•
On all high-end SRX Series devices running Junos OS Release 12.1X46 and earlier, if
application identification (AppID) is enabled, performance degradation is seen in
comparison with devices running Junos OS Release 12.1X47-D10 and later. This is
because the AppID function does not ignore the related sessions when AppID has
reached the terminal state, and continues with the serialization processing for those
sessions. It is important to note that Junos OS Release 12.1X47 and later releases use
advanced AppID. PR1046509
Application Layer Gateways (ALGs)
•
On all high-end SRX Series devices in a chassis cluster with TCP-based ALG enabled
and the TCP keepalive mechanism used on the TCP server and client, after a data
plane redundancy group (RG1+) failover, the keepalive message causes the mbuf to
be held by the ALG until the session timeout. As a result, a high mbuf usage alarm is
generated. Application communication failure occurs due to lack of mbuf. PR1031910
•
On all high-end SRX Series devices with the SIP ALG and NAT enabled, if you place a
call on hold or off hold many times, each time with different media ports, the resource
in the call is used, resulting in one-way audio. Tearing down the call clears the resource,

Dynamic Host Configuration Protocol (DHCP)
•
On all high-end SRX Series devices configured as a DHCP server (using the jdhcpd
process), when the DHCP server gets a new request from a client and applies an IP
address from the authentication process (authd), the jdhcpd process communicates
with authd process twice as expected (once for the DHCP discovery message and
once for the DHCP request message). If the authentication fails in the first message,
the authd process will indefinitely wait for the second authentication request. However,
the jdhcpd process never sends the second request, because the process detects that
the first authentication did not occur. This causes memory leak on the authd process,
and the memory might get exhausted, generating a core file and preventing DHCP
server service. High CPU usage on the Routing Engine might also be observed. PR1042818
General Packet Radio Service (GPRS)
•
On all high-end SRX Series devices in a mobile packet core network, with GTPv2 enabled
and the device configured as a border gateway, the GTP packets might be dropped
with a missing information element drop reason message. The packets are dropped
because the information element check in processing the GTPv2 modify bearer request
is not accurate. The check should only exist when Tracking Area Updates (TAU), Routing

on SFP-T of ge-0/0/7, ge-0/0/8, or ge-0/0/9 interface, the device interface LEDs light
immediately. PR865899
•
If the secondary control link (em1) interface uses SFP-T, the interface is down when
you add node 1 to the cluster. PR873253
•
On devices in a chassis cluster, after control plane Redundancy Group (RG0) failover,
SPUs might have more if states than the new master Routing Engine. This difference
leads to sequence number mismatch and causes cold synchronization failure, and all
FPCs might reboot. After the FPCs reboot, a "split brain" situation occurs in which both
nodes become primary. PR885889
•
E2edebug traces are not generated for all the events. PR919471
Interfaces and Routing
•
On the K2-Routing Engine (64-bit Routing Engine) when speed or link mode are
statically configured on the device for the fxp0 interface, the driver for fxp0 accepts
the configuration from DCD process. The K2-Routing Engine does not propagate the
setting to the hardware driver. Instead, the driver setting is forced to auto-negotiate.
Thus, as the fxp0 interface is auto-negotiating, and the far end device is forced to
100/full, the auto-negotiation on fxp0 will detect the speed but will not detect the
duplex and hence, defaults that duplex to half-duplex. PR704740

On VLAN tagged Ethernet frames (802.1p), you cannot modify the VDSL priority bits.

Junos OS 12.1X46 Release Notes
•
When a SHDSL Mini-PIM is configured in 2-wire mode with annex mode as Annex B/G,
one of the physical interfaces does not come up. PR874249, PR882035
•
On devices in a chassis cluster, when a session created as the incoming interface is a
VPN secure tunnel interface (ST interface) and the outgoing interface is a logical tunnel
interface (LT interface), this session is incorrectly marked as active on the secondary
node. When this session expires on the secondary node, the sessions on both cluster
nodes might get deleted and interrupt the traffic. PR896299
•
When multiple routing instances are defined, DNS names in the address-book entries
might not get resolved. This results in corresponding security policies to be
nonoperational. PR919810
•
When multiple IP addresses from an overlapping subnet are configured on a single
interface, the interface enable-related or disable-related changes might not work.
PR920993
Intrusion Detection and Prevention (IDP)
•
On XLP platforms, setting the max-sessions option in an application identification
configuration did not impact the attack traffic. PR809384
•
After the Junos image is upgraded, we recommend that you download a completely
updated IDP security package and then perform the installation. Subsequent
incremental updates (default) work fine. If a complete update is not performed, the
device might end up adding only the new signatures downloaded in incremental order,
leaving the device unprotected from a large set of signatures. PR876764
•
On SRX Series devices with IDP enabled, if IDP exempt rule is configured, a change of
the IDP rule configuration (such as a change to source or destination, action, or
signature) might cause the flowd process to crash and core files are generated.
PR877865
•
When there are a large number of ASC entries (100,000 or more), and the entries are
listed using CLI command, the flowd process might crash. PR886173
•
On all high-end SRX Series devices, maximize sessions inline-tap equal mode is not
supported in Junos OS Release 12.1X46-D10. If the maximize sessions inline-tap equal
mode is configured in a release earlier than Junos OS Release 12.1X46-D10, when you
upgrade to Junos OS Release 12.1X46-D10, the configuration changes to maximize
sessions inline-tap firewall mode. PR889597
•
On SRX Series devices, the flowd process might crash when IDP is enabled using
software based pattern matching and detects more than one attack entry for the same
attack. PR907703
J-Web

•
The J-Web interface was vulnerable to HTML cross-site scripting attacks, also called
XST or cross-site tracing. PR752398
•
In J-Web, SRX Series devices fail to downgrade from Junos OS Release 12.1X46-D10
through HTTP file upload. PR918112

Resolved Issues
•
In J-Web, if the policy name was “0”, the penultimate-hop popping (PHP) function
treated it as empty, and traffic log output could not be viewed. PR853093
•
In J-Web, the LSYS operation might cause MGD to generate a core file, and compare
before commit does not work. PR889029
Network Address Translation (NAT)
•
Under certain conditions, a duplicate SNMP index might be assigned to different
interfaces by the kernel to the mib2d (Management Information Base II daemon). This
might cause mib2d and other processes such as lacpd (LACP daemon) to crash and
generate core files. PR836823
•
On devices enabled with the PIM protocol, the flowd process crashed and generated
core files, when there was a unicast PIM register message received with encapsulated
multicast data; and if NAT process was involved in the session for the received PIM
packet. This issue was observed on standalone high-end SRX Series devices, and on
devices in a chassis cluster. In the case of devices in a chassis cluster, the flowd process
crashed on both node 0 and node 1. PR842253
•
In a root system, the destination and static NAT rule cannot send system log and trap
messages when the number of sessions reaches the threshold value. In a logical-system,
the source, destination, and static NAT rule cannot send system log and trap messages
when the number of sessions reaches the threshold value. PR905359
•
On devices in a chassis cluster, the chassis cluster rule number of sessions in the SNMP
query or walk result is the sum of the real number of sessions of the primary node and
the secondary node. PR908206
•
On all high-end SRX Series devices, when source NAT is configured with persistent
NAT enabled, sometimes the persistent NAT bindings leak on the central point. PR910116
Routing Policy and Firewall Filters
•
If more than 10 virtual routers (routing instances) or logical systems (LSYS) are
configured on a device, DNS fails to resolve addresses. A maximum of only 10 routing
instances and LSYS can be configured per DNS name server. PR896174
Screen
•
On all high-end SRX Series devices with IP spoofing screen enabled, the routing table
search fails when it is locked by the system. As a result, false positives occur on IP
spoofing detection. PR901507
•
On all high-end SRX Series devices, security screen are not allocated for more than
165 zones due to memory limitation. If a security screen is enabled for more than 165
zones, only 165 zones are actually enabled and the memory is exhausted by the screen
allocation, resulting in traffic interruption. PR913052
Security
•
The glob implementation in libc allows authenticated remote users to cause a denial
of service (CPU and memory consumption) via crafted glob expressions that do not
match any pathnames. This vulnerability can be exploited against a device running
Copyright © 2016, Juniper Networks, Inc.

Junos OS 12.1X46 Release Notes
Junos OS with FTP services enabled to launch a high CPU utilization partial denial of
service attack.
Please refer to JSA10598 for additional information. PR558494
•
If Proxy ARP is enabled on an unnumbered interface, an attacker can poison the ARP
cache and create a bogus forwarding table entry for an IP address, effectively creating
a denial of service for that subscriber or interface. When Proxy ARP is enabled on an
unnumbered interface, the router will answer any ARP message from any IP address
which could lead to exploitable information disclosure.
Please refer to JSA10595 for additional information. PR842092
System Log
•
On SRX3400 and SRX3600 devices, the following system logs are seen in the messages
file:
sfchip_show_rates_pfe: Fchip Plane 0, dpc 0, pfe <1/2/3>: Invalid dpc
These system logs do not affect the device. PR738199

•
On all high-end SRX Series devices, when a Routing Engine card is removed and placed
again, swapped, or rebooted, the following error message appears in the system log
for an hour:
No response from the other routing engine for the last 300 seconds
PR875189
•
SRX5600 and SRX5800 devices with an SRX5K-SPC-4-15-320 (next-generation
SPC) might generate one of the following system logs on the messages file:
spu_mac_get_linkstate:spu (<fpc#>/<pic#>) – phy link<link#> failed
spu_mac_get_linkstate:%PFE-3:(<fpc#>/<pic#>) –MAC layer link failed
In this condition, the affected SPU cannot do any flow processing until the system is
rebooted. PR914736

Junos OS 12.1X46 Release Notes
•
The set chassis cluster cluster-id cluster-id node node reboot operational mode command
is missing from the Administration tab. This operational mode command sets the
chassis cluster identifier (ID) and node ID on each device, and reboots the devices to
enable clustering. This command has two options: cluster-id cluster-id (0 through 255)
and node node (0 or 1). The system uses the chassis cluster ID and chassis cluster node
ID to apply the correct configuration for each node (for example, when you use the
apply-groups command to configure the chassis cluster management interface). The
chassis cluster ID and node ID statements are written to the EPROM, and the statements
take effect when the system is rebooted. Setting a cluster ID to 0 is equivalent to
disabling a cluster. Support for extended cluster identifiers (more than 15 identifiers)
added in Junos OS Release 12.1X46-D10. A cluster ID greater than 15 can only be set
when the fabric and control link interfaces are connected back-to-back. The command
has the following privilege level: maintenance.
If you have a cluster set up and running with an earlier release of Junos OS, you can
upgrade to Junos OS Release 12.1X46-D10 or later and re-create a cluster with cluster
IDs greater than 16. If for any reason you decide to revert to the previous version of
Junos OS that did not support extended cluster IDs, the system comes up with
standalone devices after you reboot. If the cluster ID set is less than 16 and you roll
back to a previous release, the system comes back with the previous setup.

You can directly upgrade or downgrade between any two Junos OS releases that are
within three releases of each other.

Migration, Upgrade, and Downgrade Instructions
•
Example: Direct release upgrade
Release 10.3 → (bypassing Releases 10.4 and 11.1) Release 11.2
To upgrade or downgrade between Junos OS releases that are more than three releases
apart, you can upgrade or downgrade first to an intermediate release that is within three
releases of the desired release, and then upgrade or downgrade from that release to the
desired release.
•
Example: Multistep release downgrade
Release 11.3 → (bypassing Releases 11.2 and 11.1) Release 10.4 → Release 10.3
Juniper Networks has also provided an even more efficient method of upgrading and
downgrading using the Junos OS EEOL releases. EEOL releases generally occur once a
calendar year and can be more than three releases apart. For a list of, EEOL releases, go
to http://www.juniper.net/support/eol/junos.html
You can directly upgrade or downgrade between any two Junos OS EEOL releases that
are within three EEOL releases of each other.
•
Example: Direct EEOL release upgrade
Release 9.3 (EEOL) → (bypassing Releases 10.0 [EEOL] and 10.4 [EEOL]) Release 11.4
(EEOL)
To upgrade or downgrade between Junos OS EEOL releases that are more than three
EEOL releases apart, you can upgrade first to an intermediate EEOL release that is within
three EEOL releases of the desired EEOL release, and then upgrade from that EEOL
release to the desired EEOL release.
•
Example: Multistep release upgrade using intermediate EEOL release
Release 8.5 (EEOL) → (bypassing Releases 9.3 [EEOL] and 10.0 [EEOL]) Release 10.4
(EEOL) → Release 11.4 (EEOL)
You can even use a Junos OS EEOL release as an intermediate upgrade or downgrade
step if your desired release is several releases later than your current release.
•
Example: Multistep release upgrade using intermediate EEOL release
Release 9.6 → Release 10.0 (EEOL) → Release 10.2
For additional information about how to upgrade and downgrade, see the Junos OS
Installation and Upgrade Guide.
Upgrading an AppSecure Device
Use the no-validate Option for AppSecure Devices.
For devices implementing AppSecure services, use the no-validate option when upgrading
from Junos OS Release 11.2 or earlier to Junos OS 11.4R1 or later. The application signature
package used with AppSecure services in previous releases has been moved from the
configuration file to a signature database. This change in location can trigger an error
Copyright © 2016, Juniper Networks, Inc.
203
Junos OS 12.1X46 Release Notes
during the validation step and interrupt the Junos OS upgrade. The no-validate option
bypasses this step.
Network and Security Manager Support
Network and Security Manager (NSM) support for High-End SRX Series Services Gateways
with Junos OS 12.1X46-D10 is available only with NSM versions 2012.2R6 / 2012.1R10 and
later. For additional information, see Network and Security Manager documentation.
Upgrade and Downgrade Scripts for Address Book Configuration
Beginning with Junos OS Release 11.4 or later, you can configure address books under
the [security] hierarchy and attach security zones to them (zone-attached configuration).
In Junos OS Release 11.1 and earlier, address books were defined under the [security zones]
hierarchy (zone-defined configuration).
You can either define all address books under the [security] hierarchy in a zone-attached
configuration format or under the [security zones] hierarchy in a zone-defined configuration
format; the CLI displays an error and fails to commit the configuration if you configure
both configuration formats on one system.
Juniper Networks provides Junos operation scripts that allow you to work in either of the
address book configuration formats (see Figure 7 on page 205).

Running Upgrade and Downgrade Scripts on page 205
About Upgrade and Downgrade Scripts
After downloading Junos OS Release 12.1, you have the following options for configuring
the address book feature:
•
Use the default address book configuration—You can configure address books using
the zone-defined configuration format, which is available by default. For information
on how to configure zone-defined address books, see the Junos OS Release 11.1
documentation.
•
Use the upgrade script—You can run the upgrade script available on the Juniper Networks
support site to configure address books using the new zone-attached configuration
format. When upgrading, the system uses the zone names to create address books.
For example, addresses in the trust zone are created in an address book named
trust-address-book and are attached to the trust zone. IP prefixes used in NAT rules
remain unaffected.
After upgrading to the zone-attached address book configuration:
•
You cannot configure address books using the zone-defined address book
configuration format; the CLI displays an error and fails to commit.
•
You cannot configure address books using the J-Web interface.
For information on how to configure zone-attached address books, see the Junos OS
Release 11.4 documentation.

Migration, Upgrade, and Downgrade Instructions
•
Use the downgrade script—After upgrading to the zone-attached configuration, if you
want to revert to the zone-defined configuration, use the downgrade script available
on the Juniper Networks support site. For information on how to configure zone-defined
address books, see the Junos OS Release 11.1 documentation.
NOTE: Before running the downgrade script, make sure to revert any
configuration that uses addresses from the global address book.

Run the downgrade script.
Running Upgrade and Downgrade Scripts
The following restrictions apply to the address book upgrade and downgrade scripts:
•
The scripts cannot run unless the configuration on your system has been committed.
Thus, if the zone-defined address book and zone-attached address book configurations
are present on your system at the same time, the scripts will not run.
•
The scripts cannot run when the global address book exists on your system.
•
If you upgrade your device to Junos OS Release 11.4 or later and configure logical
systems, the master logical system retains any previously configured zone-defined
address book configuration. The master administrator can run the address book upgrade
script to convert the existing zone-defined configuration to the zone-attached

Junos OS 12.1X46 Release Notes
configuration. The upgrade script converts all zone-defined configurations in the master
logical system and user logical systems.
NOTE: You cannot run the downgrade script on logical systems.
For information about implementing and executing Junos operation scripts, see the Junos
OS Configuration and Operations Automation Guide.
Upgrade Policy for Junos OS Extended End-Of-Life Releases
Support for upgrades and downgrades that span more than three Junos OS releases at
a time is not provided, except for releases that are designated as Extended End-of-Life
(EEOL) releases. EEOL releases provide direct upgrade and downgrade paths—you can
upgrade directly from one EEOL release to the next EEOL release even though EEOL
releases generally occur in increments beyond three releases.
You can upgrade or downgrade to the EEOL release that occurs directly before or after
the currently installed EEOL release, or to two EEOL releases before or after. For example,
Junos OS Releases 10.0, 10.4, and 11.4 are EEOL releases. You can upgrade from Junos
OS Release 10.0 to Release 10.4 or even from Junos OS Release 10.0 to Release 11.4.
However, you cannot upgrade directly from a non-EEOL release that is more than three
releases ahead or behind. For example, you cannot directly upgrade from Junos OS
Release 10.3 (a non-EEOL release) to Junos OS Release 11.4 or directly downgrade from
Junos OS Release 11.4 to Junos OS Release 10.3.
To upgrade or downgrade from a non-EEOL release to a release more than three releases
before or after, first upgrade to the next EEOL release and then upgrade or downgrade
from that EEOL release to your target release.
For more information on EEOL releases and to review a list of EEOL releases, see
http://www.juniper.net/support/eol/junos.html .
Hardware Requirements
Transceiver Compatibility for SRX Series Devices
We strongly recommend that only transceivers provided by Juniper Networks be used
on high-end SRX Series Services Gateways interface modules. Different transceiver types
(long-range, short-range, copper, and others) can be used together on multiport SFP
interface modules as long as they are provided by Juniper Networks. We cannot guarantee
that the interface module will operate correctly if third-party transceivers are used.
Please contact Juniper Networks for the correct transceiver part number for your device.
