supported in FOS v7.4.0b.
•
Brocade 6543 (embedded switch)
FOS v7.4.1 New Features & Support
In addition to fixes for defects, FOS v7.4.1 includes following enhancements:
•
•
•
Support POSIX style regular expression for <alias_pattern> parameter in the zoneShow --alias
<alias_pattern> CLI.
SNMP enhancement to MIB object ifOperStatus to report port online/offline state independently from the
value of ifAdminStatus.
Support SCP/SFTP protocol for SNMP MIB objects hwinfospsaveSet and hwUpdateFile for initiating
firmwareDownload and supportSave through SNMP.
FOS v7.4.1 also includes the following features introduced in FOS v7.4.0b that enable Brocade Gen 5 fabric
switches as source switches to be monitored by the Brocade Analytics Monitoring Platform:
•
•
Support for virtual tap (vTap)
o vTap is a Brocade Gen 5 Flow Vision capability enabled on a fabric switch to mirror selected
frames to Analytics Monitoring Platform for analysis. A new pre-defined flow named
“sys_analytics_vtap” supports vTap.
o vTap supports automatic discovery of Analytic F_Port (AF_Port) when a Brocade Analytics
Monitoring Platform is attached to the fabric. An AF_Port is a mirror port on the Analytics
Monitoring Platform designated as the destination of information sent from vTap-enabled ports on
a fabric switch.
Support for Analytics E_Port (AE_Port) connectivity between fabric switches and the Brocade Analytics
Monitoring Platform through Analytics Switch Link (ASL)
o ASLs are Gen 5 Fibre Channel links dedicated for carrying information from vTap-enabled ports on
fabric switches to Brocade Analytics Monitoring Platform.

o ASLs do not carry normal data traffic unless they are the only paths from hosts to targets.
Enhancement to MAPS for monitoring AE_Port and vTap
o Add Fabric Performance Impact (FPI) monitoring for latency and congestion monitoring on AE_Port
o Add FPI monitoring for back-end ports with active vTap on a fabric switch
o Add Switch Resource monitoring for vTap traffic IOPS with active vTap on a fabric switch
FOS v7.4 Obsoleted FOS Features
The following features supported in FOS v7.3 and earlier releases are obsolete beginning with FOS v7.4:
Fabric Watch
Advanced Performance Monitoring (APM)
Users running Fabric Watch for switch monitoring in FOS v7.3 are advised to convert to MAPS monitoring
before upgrading to FOS v7.4. Converting Fabric Watch to MAPS before upgrading to FOS v7.4 can preserve
Fabric Watch threshold configurations. If users choose to upgrade to FOS v7.4 without converting to MAPS,
Fabric Watch will stop functioning after the firmware upgrade and the Fabric Watch thresholds cannot be
automatically migrated for use by MAPS. Please refer to the Fabric OS MAPS Administrator’s Guide for step-bystep migration instructions.
Users running APM in FOS v7.3 are required to remove all monitors before upgrading to FOS v7.4 by using the
following commands:
1. Enter perfdeleemonitor to remove all End-to-end monitors.
2. Enter perfcfgsave to save this change.
3. Enter fmmonitor --delmonitor to remove all filter monitors.
4. Enter fmmonitor --delete frametype to remove the specified user-defined frametype.
5. Enter perfttmon --delete to remove all switch level Top Talker monitors.
6. Enter perfttmon --delete fabricmode to remove fabric mode Top Talker monitors.
After upgrading to FOS v7.4, the APM monitors will stop functioning. Users can use the Flow Vision features as
part of Fabric Vision for performance monitoring. Please refer to the Fabric OS Flow Vision Administrator’s
Guide for detailed instructions on removing APM monitors and Flow Vision feature configurations.
Brocade Fabric Vision licenses are required for MAPS and Flow Vision. The combination of Brocade Fabric
Watch license and Brocade APM license enables the MAPS and Flow Vision features. For switches with only
Fabric Watch licenses or only APM licenses, users can acquire and install the missing license to acquire MAPS
and Flow Vision features.

FOS v7.4 New Feature Descriptions
New Hardware Support
FOS v7.4 adds support for the following new hardware:
Brocade-branded 4GB external USB flash drive
IP Extension features for Brocade 7840
FOS v7.4 introduces IP Extension support for the Brocade 7840. Users can use this capability to extend IP
storage for replication and disaster recovery in much the same way as Fibre Channel storage while taking
advantage of the compression, encryption, QoS, and trunking features available in the Brocade 7840.
A Brocade 7840 running FOS v7.4 can support both FCIP Extension and IP Extension at the same time. IP
Extension includes the following:
Support for system configuration for IP Extension
Support for GbE port configuration for IP Extension
Tunnel configuration for IP Extension
Adaptive Rate Limiting
TCP/IP Features
Traffic Control List
Support System Configuration for IP Extension
FOS v7.4 supports users configuring Brocade 7840 for both FCIP Extension and IP Extension (hybrid mode). By
default, Brocade 7840 supports FCIP Extension only. Changing a Brocade 7840 between FCIP-only and hybrid
mode requires a switch reboot.
Support GE Port Configuration for IP Extension
FOS v7.4 supports users configuring the front end 1/10 GbE ports as LAN ports on a Brocade 7840 for hybrid
mode. These ports are used to connect to IP storage devices on the LAN side. FOS v7.4 supports static Link
Aggregation Group (LAG) configuration so that multiple LAN ports can be assigned to the same LAG group.
Tunnel configuration for IP Extension
FOS v7.4 supports user configuration of IP tunnels on a Brocade 7840 in the same way as FC tunnels are
configured. IP tunnels and FC tunnels are all represented under virtual E-port (VE). Each VE is configured as a
FC-only tunnel or as both FC and IP tunnels. Trunking, QoS, and compression are supported on IP tunnels as
they are for FC tunnels.
Adaptive Rate Limiting (ARL)
FOS v7.4 supports all ARL features available on the FCIP Extension for IP Extension. The static distribution of
unused bandwidth is hierarchical.
TCP/IP Features
FOS v7.4 supports the following TCP/IP features for IP Extension.
LAN side jumbo frames
IPv4 and IPv6 for LAN side
Maximum 512 TCP connections per Data Processor (DP)
Maximum 512 TCP open requests per second per DP
Maximum 64 UDP flows per DP
DSCP/VLAN L2CoS marking
Segment Preservation
Each LAN TCP window will be 64K by default. If TCP window scaling is requested, the maximum advertised
window is 256K. The maximum window per connection is 2M irrespective of the advertised window.
Fabric OS 7.4.1d Release Notes v1.0
Page 10 of 160
Untagged and single tagged packets are supported.
Stacked/double (IEEE 802.1ad) tagged packets from hosts are not supported. Packets will be dropped.
Traffic Control List
FOS v7.4 supports Traffic Control List (TCL) to manage and route IP flows. Each TCL is identified by a unique
user configured name. FOS v7.4 supports maximum 128 TCLs. System generated default TCL will drop all the
incoming packets.
FCIP Enhancements to Brocade 7840
Base Switch Support for 7840
FOS v7.4 enhances Virtual Fabric support on 7840 switches to include the base switch, i.e., to support XISL.
Users can configure E_port (ISL over FC), EX_port (IFL over FC), and VE_port (ISL over GE) in base switch. The
maximum number of logical switches supported — including the base switch — remains four.
FCIP Hot Code Load (HCL)
FOS v7.4 enhances FCIP HCL support in the following conditions, which were excluded in FOS v7.3.
Support concurrent FCIP HCL on all 7840 switches in the configuration
Support multiple sites for FCIP HCL
Monitoring and Alerting Policy Suite (MAPS) Enhancements
FOS v7.4 has a number of important MAPS feature enhancements. These include:
Basic monitoring without Fabric Vision license
Monitor NPIV device login limits
Monitor backend ports
Monitor FCIP circuit QoS
Monitor FCIP circuit RTT and jitter on Brocade 7800 and FX8-24 blade
Fabric Performance Impact monitoring enhancement
Slow drain device quarantine action for Fabric Performance Impact monitoring
Port toggle action
FICON notification action
Alert quiet time support
Usability enhancements
Monitoring without Fabric Vision license
FOS v7.4 introduces a new basic monitoring capability in MAPS. The basic monitoring capability allows end
users without Fabric Vision licenses on their switches to use MAPS to monitor overall switch status, FRU health,
and switch resource categories under the new pre-defined MAPS policy dflt_base_policy.
Monitor NPIV device login limits
FOS v7.4 introduces MAPS monitoring of NPIV login limits. FOS has limits on the number of NPIV devices that
can login to a physical F_port. MAPS monitors the percentage of logged in NPIV devices relative to the
maximum number of NPIV logins allowed on the F_port to alert users before the limit is reached.
Monitor backend ports
FOS v7.4 introduces back-end port error monitoring in MAPS. Users can take early recovery actions if any of the
monitored back-end errors have crossed specified thresholds. Typical recovery actions include SerDes tuning
on a switch or reseating blades. For detailed instructions on these actions, please contact your support
provider for additional assistance.
Fabric OS 7.4.1d Release Notes v1.0
Page 11 of 160
Monitor FCIP circuit QoS
FOS v7.4 enhances FCIP QoS monitoring in MAPS to add monitoring of Fibre Channel QoS parameters at circuit
level. The circuit QoS monitoring combined with the tunnel QoS monitoring available since FOS v7.3 provides
additional granularity to monitor the FCIP link performance.
Monitor FCIP circuit RTT and jitter on 7800 and FX8-24
MAPS monitors circuit round trip time (RTT) and jitter statistics in FOS v7.3 on Brocade 7840. FOS v7.4
supports these two FCIP circuit monitoring elements on Brocade 7800 and FX8-24 blade so that they are
available to 8G FC extension platforms.
Fabric Performance Impact monitoring enhancement
FOS v7.4 enhances Fabric Performance Impact (FPI) monitoring to add a new IO_LATENCY_CLEAR state so that
end users can receive notification when latency conditions are cleared. FOS v7.4 enhances FPI monitoring by
adding latency counter monitoring on all ports to detect potential transient spikes of latency conditions. In
addition, FOS v7.4 moves port TX, RX, and UTIL monitoring systems to the FPI category from the Port Health
category in FOS v7.3 and earlier releases so that all potential congestion conditions are reported under the FPI
category.
Slow drain device quarantine action for Fabric Performance Impact monitoring
FOS v7.4 introduces a new MAPS action that automatically isolates slow drain devices when they are detected
by FPI monitoring. This frees up buffer credits for normal devices that are sharing the same links and mitigates
the effect due to presence of slow drain devices in the fabric.
Port toggle action for Fabric Performance Impact monitoring
FOS v7.4 introduces Port Toggle as an action which automatically recovers slow drain device conditions when
they are detected by FPI monitoring. A port toggle, (which is a port disable followed by a port enable) can
recover the ports from some slow drain device conditions or force traffic failover to an alternate path.
FICON notification action
FOS v7.4 introduces FICON notification as a new action that enables MAPS events to be sent to FMS with
detailed event information upon rule violations. FMS CUP can translate these MAPS events into FICON-specific
Health Summary Check reports.
Alert quiet time support
FOS v7.4 introduces a quiet time support for RASLOG and EMAIL alert actions. This feature allows end users to
configure within a rule a period of time not to receive duplicated alerting actions after the first alert has already
been sent.
Usability enhancements
FOS v7.4 has a number of usability enhancements to MAPS. These include:
Allow none to be used as an email address to clear previously configured email addresses in the CLI command
mapsconfig.
Enhanced Temperature Sensor monitoring so that actions are triggered on change of Temperature Sensor (TS)
states.
Modified FRU monitoring so that the states being monitored are more accurate and useful for operations.
An upper limit to the number of rules that can be created in a policy. The maximum number of rules in a policy
is dependent on the character length of each rule name.
Flow Vision Enhancements
FOS v7.4 provides the following enhancements to Flow Vision:
All F_Port Flow Monitoring
FOS v7.4 introduces a system predefined learning flow named sys_mon_all_fports to monitor performance on
all F_ports in a switch. Flow learning on all F_ports provides a continuous, automatic, and comprehensive view
of application traffic patterns for all device connections.
Fabric OS 7.4.1d Release Notes v1.0
Page 12 of 160
Scalability Improvement
FOS v7.4 increases the scalability limit supported by Flow Vision. In particular, the total number of sub-flows
supported by chassis switches is increased to 2048 and by fixed port switches is increased to 512.
Identify All Devices in a Flow
FOS v7.4 supports displaying all zoned devices in a flow by introducing a new option -allzoned to the Flow
Vision command. This will identify all zoned devices for a flow defined on an E_Port or F_Port.
Fabric Flow Dashboard
FOS v7.4 introduces support of a Flow Dashboard that provides information for a flow from all the available
data points in the fabric through which it can pass. With all relevant data summarized for a flow of interest,
users are able to more easily troubleshoot and identify the root cause of various issues that may occur.
ClearLink Diagnostic (D_Port) Enhancements
FOS v7.4 implements the following D_Port feature enhancements.
Link Power (dB) Loss Calculation
FOS v7.4 supports calculating TX and RX power loss of a link with D_Port tests. D_Port tests include the power
loss calculation to provide additional details on the health of physical media of links.
Dynamic D_Port and On-demand D_Port with DWDM
FOS v7.4 enhances D_port pre-provision feature to allow administrators to pre-provision certain ports
connected to DWDM links. With the pre-provisioned list, dynamic D_port and on-demand D_port tests can start
automatically on those ports with the optical loopback test skipped.
CLI Command Hierarchical Help Display
FOS v7.4 enhances the help page for D_port CLI commands so that only the relevant sub-options are displayed
when a command action is specified for the portCfgDport and portDportTest commands.
Peer Zoning Support
FOS v7.4 introduces support for Peer Zoning as defined in the FC-SW-6 and FC-GS-7 standard. In a Peer Zone
configuration, membership in a zone is differentiated into principal members and non-principal or peer
members. Peer Zoning configuration allows communication between a principal member and any peer
member but does not allow communication between two peer members or between two principal members. By
adopting Peer Zoning, users can simplify zoning configuration and management, improve performance, and
increase scalability.
Target Driven Zoning support
FOS v7.4 introduces the Target Driven Zoning feature that allows end devices to create Peer Zone
configurations through inband commands. This feature enables zoning to be configured by management
software on storage devices and reduces the manual configuration needed on switches.
Lossless DLS enhancement
FOS v7.4 introduces a routing enhancement to support lossless Dynamic Load Sharing (DLS) in a 2-hop
topology. This enhancement allows adding links or switches in existing paths that are up to 2 hops between a
host and a target, including the new link that is coming online, to ensure lossless and in-order frame delivery.

FOS v7.4 has a number of enhancements in FCR. These enhancements include:
Location Embedded LSAN zone
FOS v7.4 introduces the location-embedded LSAN zone feature. A location-embedded LSAN zone specifies in
the LSAN zone name the remote fabric ID that shares devices. The corresponding FCR switch will use this
information in the LSAN zone names to store only these entries for the locally connected edge fabric. As a
result. users are now able to configure more LSAN zones across a backbone fabric.
Increase Number of Imported Proxy Devices
FOS v7.4 increases the maximum number of proxy devices that can be imported into each edge fabric to
4000. This limit applies to the cumulative number of all proxy devices created on all translate domains in the
edge fabric. FOS versions prior to v7.4 support 2000 proxy devices as the limit for this number.
Sort WWNs in lsanzoneshow CLI
FOS v7.4 supports sorting WWNs in the CLI command lsanzoneshow output. A new -o or -sort option is added
to the CLI command to display entries in sorted order by WWNs for each LSAN zone listing.
Support Port Range for portcfgexport and portcfgvexport CLI
FOS v7.4 supports port range as input parameters for the portcfgexport and portvexport CLI commands so that
multiple ports can be configured as EX-port or VEX-port at the same time.
Support Peer Zoning with FCR
FOS v7.4 supports Peer Zoning in LSAN zones if users have configured a peer zone in an edge fabric. Peer
zoning rules and RSCN distribution will be enforced by edge fabric switches.
Support New Domain ID Range for Front and Translate Phantom Domains
FOS v7.4 supports assigning for an FCR the front domain ID in the range of 160 through 199 and the translate
domain ID in the range of 200 through 239. Users can use the CLI command fcrConfigure -resetPhantomDomain to use the new range to avoid conflicting with the real switch domain IDs.
Security Enhancements
FOS v7.4 has a number of important security enhancements:
Obfuscation of RADIUS Shared Secrets
FOS v7.4 supports obfuscation of the RADIUS shared secrets so that they are not stored as plaintext. With this
option, stored shared secrets are not visible as plaintext in configUpload files and SupportSave files.
Import/Export Syslog Server Certificates
FOS v7.4 adds the support of importing and exporting a syslog server certificate to support syslog over TLS. A
syslog server CA certificate can be imported from a remote host or exported to a remote host.
Password Policy Enhancement for Root Password Change
FOS v7.4 adds a new option in the switch account password policy to allow root password change by root
account login sessions without prompting for the existing (old) password.
secCryptoCfg CLI Command
FOS v7.4 supports a new CLI secCryptoCfg command to configure the set of acceptable cryptographic
algorithms for the SSH and HTTPS protocols on a switch. Administrators can use this new CLI command to
mandate various cryptographic algorithms conform to their policies.
Default Account Password Change
FOS v7.4 modifies the behavior of default switch account password change. Login to admin account would only
prompt changes to the default admin and user account passwords. The default root and factory account
passwords change would only be prompted when login to the switch as root.

Time Server Enhancements
FOS v7.4 enhances Time Server to support Network Time Protocol (NTP) server configuration distribution to
Access Gateway switches. This enhancement allows AGs, including cascaded AG connections, to receive the
same NTP server configuration from a connected fabric.
SNMP Enhancements
FOS v7.4 implements the following SNMP enhancements.
Log Messages for SNMPv3 Authentication
FOS v7.4 logs SNMP authentication success and failure as audit log messages to track the authentication
results for SNMPv3 requests.
SNMPv3 Individual Inform Tag
FOS v7.4 enhances SNMPv3 configuration to allow SNMP informs to be enabled or disabled at individual
receiver host level. With this enhancement, users can configure some receivers to get SNMP informs, while
other receivers get SNMP traps.
Disable SNMP Write Access
FOS v7.4 changes the default SNMP configuration to have SNMP write disabled. This affects the default switch
configuration loaded with FOS v7.4 on a new switch from factory.
Obsoletes Fabric Watch and Advanced Performence Monitoring MIBs
FOS v7.4 obsoletes the following MIBs associated with Fabric Watch and Advanced Performance Monitoring
feature: swFwSystem, swBlmPerfMnt, swTopTalker.
RDP Enhancements
FOS v7.4 enhances the Read Diagnostic Parameter (RDP) support which includes the following:
Enable polling to refresh RDP data cache at a default 4 hour interval.
Include signal power loss information in the sfpShow --link or sfpShow --pid options.
Include corrected and uncorrected FEC blocks in portShow --link or portShow --pid options.
Firmware Download Enhancements
FOS v7.4 introduces the following important enhancements for firmware download.
Staged Firmware Download
FOS v7.4 supports staged firmware download so that users can download firmware package to a switch first
and choose to install and activate the downloaded firmware at a later time.
Firmware Clean Installation
FOS v7.4 supports firmware clean installation. This installs a firmware package without retaining the existing
configuration or maintaining HA. With this feature, customers receiving a new switch from factory can install
firmware in a single step to the desired version that their networks are running, without going through multiple
steps of non-disruptive firmware download.
Firmware Auto Sync Enhancement
FOS v7.4 enhances the firmware auto sync feature to support automatic synchronization of firmware versions
on a standby CP with a version different from the active CP. If an active CP runs FOS v7.4 or higher:
A standby CP with firmware version as early as FOS v6.4 can be upgraded automatically.
A standby CP with firmware version later than FOS v7.4 can be downgraded automatically.
Firmware Integrity Check
FOS v7.4 introduces a firmwareCheck CLI command to check the integrity of firmware packages already
installed on the switch. If any of the files or packages as part of firmware has been changed, the firmware
integrity check will fail and notify users which package has failed the check.
Fabric OS 7.4.1d Release Notes v1.0
Page 15 of 160
Challenge-Response Authentication
FOS v7.4 introduces support for SSH servers configured with “keyboard-interactive” as defined in IETF RFC
4256 as authentication method to be used with SCP or SFTP for firmware download, support save, and config
upload/download commands. With this SSH server configuration, FOS v7.4 only supports account passwords
as a form of challenge-response authentication.
RAS Enhancements
FOS v7.4 supports the following RAS enhancements:
WWN Card Replacement Enhancements
FOS v7.4 enhances the procedure for field replacement of WWN cards in chassis based systems. WWN cards
are chassis FRUs that contain chassis WWNs and other information. Each chassis has two WWN cards for
redundancy. FOS v7.4 enhances WWN card handling so that certain error or data corruptions associated with
WWN cards can be recovered in the field.After users replace a single defective WWN card with a new one,
some data can be restored from the current/non-defective WWN card to the newly replaced WWN card. In
addition, the system periodically checks the integrity of the WWN cards and logs RASLOG error messages if
problems are detected.
Show RASLOG Messages within a Timeframe
FOS v7.4 adds options to errdump and errshow CLI command so that only RASLOG messages within the
specified beginning and end time will be shown, instead of all RASLOG messages.
Audit Log Enhancements
FOS v7.4 enables audit log by default for all classes of messages. FOS v7.4 increases the maximum number of
audit log messages stored on a switch to 1024 from 256.
Clihistory Identify Command Virtual Fabric FID
FOS v7.4 enhances cliHistory so that FID contexts will be shown along with the command line. With this
enhancement, clihistory in a support save file includes the FID information for support and debug usage.
Zoning Enhancements
FOS v7.4 adds the following enhancements to standard zoning to simplify zoning configuration:
List Zones with Specific Alias
FOS v7.4 adds support to zoneshow command to display only the zone configurations that match a given alias
instead of the entire zone database. Administrators can use this enhancement to quickly locate certain zone
configurations that contain a specific alias or alias prefix.
Sort zoneShow Command Output by WWN
FOS v7.4 enhances the zoneShow --sort command output in sorted order for both (D,I) and WWN members.
Indicate offline members in zoneShow output
FOS v7.4 provides a new option --validate to the zoneshow command to indicate members in the configuration
but not online in the fabric. Administrators can use this enhancement to quickly discover the online and offline
members in a zone configuration.
Traffic Isolation (TI) Zoning Enforcement enhancement
FOS v7.4 enhances TI zoning rule enforcement so that devices connected to the same local switch are also
enforced by the TI zoning rule.
TI Failover Disabled Zone Message
FOS v7.4 adds a RASLOG message ZONE-1060 to warn users if the TI zone dedicated path is the only path
available between two domain IDs.

mode in a logical switch that had FMS mode OFF.
D_Port Support in Port Descriptor
FOS v7.4 reports the state of an FC port in D_Port mode to the HOST with the Port Information Block (PIB).
Miscellaneous Enhancements
Login to Logical Switch IP
FOS v7.4 enhances Logical Switch IP address support so that logins using the logical switch IP address
automatically set the user VF context to the logical switch associated with the IP address.
Dynamic Switch Port Names
FOS v7.4 introduces a dynamic port name feature to automatically assign port names on a switch based on a
default standard format and port types. Users can enable and disable the “Dynamic port name feature” with
the configure CLI command.
Port Index Support for CLI Command portErrShow and portTestShow
FOS v7.4 enhances the portErrShow and portTestShow command to support port index as inputs, in addition to
the existing slot/port as input.
Link Reset on Loss of Sync
FOS v7.4 enhances credit recovery on backend links for 8G platforms by performing link reset (LR) on loss of
sync (LOS) events. This enhancements applies to a port where a loss of sync is detected and the peer port of
the backend link is on a 8G platform.
Enhance switchShow CLI Output
FOS v7.4 modifies switchshow -portname command output to display the port PWWN of the switch ports along
with the port names.
portLoginShow Command with History Option
FOS v7.4 enhances the portLoginShow CLI to display details of the device that last logged out from a port. This
enhancement supports the port login types of “fe” for FLOGI devices and “fd” for FDISC devices. Users can use
the -history option to show the device logout information.
Port Peer Beacon Support EX-Port
FOS v7.4 enhances port peer beacon (LCB) feature to support links with EX-ports.
BufOpMode for FC Gen5 Blades
FOS v7.4 adds support of Buffer Optimization Mode (BufOpMode) for FC Gen5 core blades and port blades.
The BufOpMode enables non-local switching in an edge ASIC chip where both E-port and F-port exist.
portStatsShow Command Display TXQ Latency

FOS v7.4 adds a “mode 2” option for the portcfglosstov CLI command to enable for both fixed-speed ports and
auto-negotiate ports.
Backend Link Failure Blade Fault Option
FOS v7.4 enhances back-end link failure handling. With this enhancement, when back-end link failure is
detected, the link is re-initialized first and the blade is faulted only when re-initialization fails. In addition, a
blade would not be faulted if there is another online port within the trunk.
DLS Support on Embedded Switches
FOS v7.4 supports DLS on the embedded platforms. Earlier FOS versions do not support dynamic load sharing
(DLS) on the FC embedded platforms.
New portChannelShow CLI Command
FOS v7.4 adds a CLI command portChannelShow to display a DPS group for one or all reachable domains.
Support preserving port2area and area2port mappings with configUpload and configDownload
FOS v7.4 supports uploading and downloading the port2area and area2port mapping tables in a configuration
file for all logical switches in a chassis through the new -map option with the existing configUpload and
configDownload CLI command.

Brocade Fabric Vision — Enables MAPS (Monitoring and Alerting Policy Suite), Flow Vision, and ClearLink
(D_Port) to non-Brocade devices. MAPS enables rules based monitoring and alerting capabilities, provides
comprehensive dashboards to quickly troubleshoot problems in Brocade SAN environments. Flow Vision
enables host to LUN flow monitoring, application flow mirroring for non-disruptive capture and deeper analysis,
and test traffic flow generation function for SAN infrastructure validation. D_Port to non-Brocade devices
allows extensive diagnostic testing of links to devices other than Brocade switches and adapters.
FICON Management Server
Server — Also known as “CUP” (Control Unit Port), enables host-control of switches in
Mainframe environments.
Enhanced Group Management — This license enables full management of devices in a data center fabric with
deeper element management functionality and greater management task aggregation throughout the
environment. This license is used in conjunction with Brocade Network Advisor application software and is
applicable to all FC platforms supported by FOS v7.0 or later.
Note: This capability is enabled by default on all Gen 5 65XX model switches and DCX 8510 platforms, and on
DCX and DCX-4S platforms that are running Fabric OS v7.0.0 or later. Gen 5 embedded switches
receive this capability by default with FOS v7.2.1 and later. Individual upgrade is required when
upgrading directly to FOS v7.2.1 on Gen 5 embedded switches. Subsequent group operations on Gen 5
embedded switches including group upgrade are supported.
Adaptive Networking with QoS — This license was deprecated beginning with FOS v7.2. All functionality
enabled by the license is now part of base FOS firmware capabilities.
Server Application Optimization — This license was deprecated beginning with FOS v7.2. All functionality
enabled by the license is now part of base FOS firmware capabilities.

these LUNs. DataFort Mode tape encryption and compression is supported beginning with the FOS v6.2.0
release on DCX platforms. Availability of the DataFort Compatibility license is limited; contact your vendor for
details.
Advanced Extension — This license enables two advanced extension features: FCIP Trunking and Adaptive Rate
Limiting. The FCIP Trunking feature allows multiple IP source and destination address pairs (defined as FCIP
Circuits) via multiple 1GbE or 10GbE interfaces to provide a high bandwidth FCIP tunnel and failover resiliency.
In addition, each FCIP circuit supports four QoS classes (Class-F, High, Medium and Low Priority), each as a
TCP connection. The Adaptive Rate Limiting feature provides a minimum bandwidth guarantee for each tunnel
with full utilization of the available network bandwidth without impacting throughput performance under high
traffic load. This license is available on the 7800, 7840, and the DCX/DCX-4S/DCX 8510-8/DCX 8510-4 for
the FX8-24 on an individual slot basis.
10GbE FCIP/10G Fibre Channel — This license enables the two 10GbE ports on the FX8-24 and/or the 10G FC
capability on FC16-xx blade ports supported on DCX 8510 platforms except for the FC16-64 blade. On the
Brocade 6510, Brocade 6520 this license enables 10G FC ports. This license is not applicable to Brocade
7840 or Brocade 6505.

Enables 10G FC capability on Brocade 6510 and Brocade 6520.
This license is available on the DCX/DCX-4S/DCX 8510-8/DCX 8510-4 on an individual slot basis.
Advanced FICON Acceleration — This licensed feature uses specialized data management techniques and
automated intelligence to accelerate FICON tape read and write and IBM Global Mirror data replication
operations over distance, while maintaining the integrity of command and acknowledgement sequences. This
license is available on the 7800, 7840, and the DCX/DCX-4S/DCX 8510-8/DCX 8510-4 for the FX8-24 on an
individual slot basis.
7800 Port Upgrade — This license allows a Brocade 7800 to enable 16 FC ports (instead of the base four
ports) and six GbE ports (instead of the base two ports). This license is also required to enable additional FCIP
tunnels and also for advanced capabilities like tape read/write pipelining.
ICL 1616-link, or Inter Chassis Links — This license provides dedicated high-bandwidth links between two Brocade
DCX chassis, without consuming valuable front-end 8Gb ports. Each chassis must have the 16-link ICL license
installed in order to enable the full 16-link ICL connections. (Available on the DCX only.)
ICL 88-Link — This license activates all eight links on ICL ports on a DCX-4S chassis or half of the ICL bandwidth
for each ICL port on the DCX platform by enabling only eight links out of the sixteen links available. This allows
users to purchase half the bandwidth of DCX ICL ports initially and upgrade with an additional 8-link license to
utilize the full ICL bandwidth at a later time. This license is also useful for environments that wish to create ICL
connections between a DCX and a DCX-4S, the latter of which cannot support more than 8 links on an ICL port.
Available on the DCX-4S and DCX platforms only.
ICL POD License — This license activates ICL ports on core blades of DCX 8510 platforms. An ICL 1st POD
license only enables half of the ICL ports on CR16-8 core blades of DCX 8510-8 or all of the ICL ports on
CR16-4 core blades on DCX 8510-4. An ICL 2nd POD license enables all ICL ports on CR16-8 core blades on a
DCX 8510-8 platform. (The ICL 2nd POD license does not apply to the DCX 8510-4.)
Enterprise ICL (EICL) License
License — The EICL license is required on a Brocade DCX 8510 chassis when that chassis
is connected to four or more Brocade DCX 8510 chassis via ICLs either as ISLs or IFLs.
This license requirement does not depend upon the total number of DCX 8510 chassis that exist in a fabric,
but only on the number of other chassis connected to a DCX 8510 via ICLs. This license is
recognized/displayed when operating with FOS v7.0.1 but enforced with FOS v7.1.0 or later.
Fabric OS 7.4.1d Release Notes v1.0
Page 20 of 160
Note: The EICL license supports a maximum of nine DCX 8510 chassis connected in a full mesh topology or up
to twelve DCX 8510 chassis connected in a core-edge topology. Refer to the Brocade SAN Scalability
Guidelines document for additional information.
WAN Rate
Rate Upgrade 1 License — The WAN Rate Upgrade 1 license provides the additional WAN throughput up
to 10 Gbps on Brocade 7840. The base configuration of Brocade 7840 without the WAN Rate Upgrade 1
license provides WAN throughput up to 5 Gbps.
WAN Rate Upgrade 2 License — The WAN Rate Upgrade 2 license provides unlimited WAN throughput (other
than the hardware limit) on Brocade 7840. The WAN Rate Upgrade 2 licenses also enable the use of two
40GbE ports on Brocade 7840. The 40GbE ports cannot be configured without the WAN Rate Upgrade 2
license. A WAN Rate Upgrade 1 license must be installed on a Brocade 7840 before a WAN Rate Upgrade 2
license is installed. A WAN Rate Upgrade 1 license cannot be removed before the WAN Rate Upgrade 2 license
has been removed.
Note:
Note: The WAN Rate Upgrade 1 and WAN Rate Upgrade 2 licenses apply only to Brocade 7840. They control
the aggregate bandwith for all tunnels on a Brocade 7840. The entire capacity controlled by the licenses
can be assigned to a single tunnel subject to hardware limitation, or a portion of the capacity can be
assigned to multiple tunnels. The total bandwidth aggregated for all tunnels should not exceed the limits
established by the licenses.

FOS Migration Considerations
This section contains important details to consider before migrating to or from this FOS release.
FOS Upgrade and Downgrade Special Considerations
Peer zoning and target driven zoning should be used in a fabric with all switches running FOS v7.4 or later. If
peer zones have been created in a mixed fabric with switches running FOS v7.3 and FOS 7.4, peer zones
created with FOS 7.4 switch are distributed to FOS 7.3 switches. When the FOS v7.3 switches are upgraded to
FOS v7.4, traffic disruption may occur on these switches.
DCX/DCX-4S/DCX8510-8 units with FCOE10-24 blades running any FOS v7.3.x can be non-disruptively
upgraded to FOS v7.4.1d. This upgrade is non-disruptive to both FC and FCoE traffic (when using FCOE10-24
blades). In FOS versions prior to v7.1.0, firmware upgrade is disruptive to FCoE traffic.
Any firmware activation on Brocade 7800, or DCX, DCX-4S, DCX 8510-8, DCX 8510-4 with FX8-24 will disrupt
I/O traffic on the FCIP links.
For FCIP, the best practice is to always operate the switch or blade at both ends of the tunnel with the same
level of Fabric OS, down to the maintenance release. Fabric OS upgrades should be done on both ends of the
FCIP tunnel concurrently.
Firmware downgrade from FOS v7.4 to FOS v7.3.0c or earlier verisons on Brocade 7840 should be avoided.
Otherwise, the Brocade 7840 may become faulty. (Downgrading to FOS v7.3.0b5 can be used as a
workaround.)
Disruptive upgrades to Fabric OS v7.4.1d are not allowed or supported from FOS v7.2.x using the optional “-s”
parameter with the firmwaredownload command. Firmware upgrade from FOS v7.2.x to FOS v7.4.1d requires
firmware upgrade to FOS v7.3.x first and then upgrade to FOS v7.4.x.
If there are multiple node EGs (encryption groups) in a fabric, please complete firmwaredownload on one node
at a time before downloading on another node.
Recommended Migration Paths to FOS v7.4.1d
Migrating from FOS v7.3
Any 8G or 16G platform running any FOS v7.3.x firmware can be non-disruptively upgraded to FOS v7.4.1d.
Migrating from FOS v7.2
Any 8G or 16G platform operating at FOS v7.2.x must be upgraded to FOS v7.3.x before upgrading to FOS
v7.4.1d.
Disruptive upgrade to FOS v7.4.1d from FOS v7.2 is not supported.

More details about Network Advisor’s new enhancements can be found in the Network Advisor 12.4.0 Release
Notes, Network Advisor 12.4.0 User Guide, and Network Advisor 12.4.0 Installation, Migration, & Transition
Guides.
Notes
Notes:
Brocade Network Advisor 12.4.0 or later is required to manage switches running FOS 7.4.0 or later.
The Brocade Network Advisor seed switch should always have the highest FOS version used in the fabric.
WebTools Compatibility
FOS v7.4.0 is qualified and supported with Oracle Java version 7 update 76 and Java version 8 update 66.
Please refer to the “Other Important Notes and Recommendations” section for more details.
SMI Compatibility
It is important to note that host SMI-S agents cannot be used to manage switches running FOS v7.4.
If users want to manage a switch running FOS v7.4 using SMI-S interface, they must use Brocade Network
Advisor’s integrated SMI agent.

Fabric OS Compatibility
The following table lists the earliest versions of Brocade software supported in this release, that is, the earliest
supported software versions that interoperate. Brocade recommends using the latest software versions to get
the greatest benefit from the SAN.
To ensure that a configuration is fully supported, always check the appropriate SAN, storage or blade server
product support page to verify support of specific code levels on specific switch platforms prior to installing on
your switch. Use only FOS versions that are supported by the provider.

Zoning Compatibility Note:
Users are recommended to upgrade to the following versions of firmware when interoperating with a switch
running FOS v7.0 or later in the same layer 2 fabric to overcome some of the zoning operations restrictions
that otherwise exist:
Main code level
Patch code levels with full zoning compatibility
FOS v6.2
FOS v6.2.2d or later
FOS v6.3
FOS v6.3.2a or later
FOS v6.4
FOS v6.4.1 or later
If there are switches running FOS versions lower than the above listed patch levels in the same fabric as a
switch with FOS v7.0 or later, then cfgsave and cfgenable operations initiated from these switches will fail if
the zoning database is greater than 128KB. In such scenarios zoning operations such as cfgsave/cfgenable
can still be performed successfully if initiated from a switch running FOS v7.0 or later.
SNMP Support
FOS v7.4.0 documents the supported MIBs in the Fabric OS MIB Reference document.
For information about SNMP support in Fabric Operating System (FOS) and how to use MIBs, see the Fabric
OS Administrator’s Guide.

Other Important Notes and Recommendations
Adaptive Networking/Flow-Based QoS Prioritization
Any 8G or 4G FC platform running FOS v6.2.2e or lower version of firmware cannot form an E-port with a 16G
FC platform when Adaptive Networking QoS is enabled at both ends of the ISL. Users must disable QoS at
either end of the ISL in order to successfully form an E-port under this condition.
Users can disable QoS via portcfgQos --disable command. Please consult Fabric OS Command Reference
manual for details related to portcfgQoS command.
When using QoS in a fabric with 4G ports or switches, FOS v6.2.2 or later must be installed on all 4G products
in order to pass QoS info. E_Ports from the DCX to other switches must come up AFTER 6.2.2 is running on
those switches.
When FOS is upgraded from v7.1.x to v7.2.0 or later:
o
If the Adaptive Networking license was NOT installed in v7.1.x, all ports will have QOS
disabled following the firmware upgrade and links will come up in normal mode.
o
If the Adaptive Networking license was installed in v7.1.x, there will be no change in port
QOS mode following the upgrade.
o
If the remote port supports QOS and QOS is not explicitly disabled on the local or remote
port, the link will come up in QOS mode. Otherwise, the link will come up in normal mode.
Fabric OS 7.4.1d Release Notes v1.0
Page 34 of 160
If FOS v7.2 or later is factory installed (or by firmwarecleaninstall), Adaptive Networking features are always
available. This matches the behavior of the Brocade 6520 and all products shipping with prior versions of FOS
and with the Adaptive Networking license factory installed.
o
Ports will come up in AE mode by default
o
If the remote port supports QOS and is not explicitly disabled, the link will come up in QOS
mode. Otherwise, the link will come up in normal mode.
Access Gateway
Users who want to utilize Access Gateway’s Device-based mapping feature in the ESX environments are
encouraged to refer to the SAN TechNote GA-TN-276-00 for best implementation practices. Please follow these
instructions to access this technote:
1. Log in to http://my.brocade.com
2. Go to Documentation > Tech Notes.
3. Look for the Tech Note on Access Gateway Device-Based Mapping in VMware ESX Server.
D_Port
The 16Gb QSFP optics used in FC16-64 blade do not support electrical loopback and optical loopback tests.
Support is limited to:
o
Link traffic tests across the 16Gb QSFPs
o
Roundtrip link latency measurements
o Link distance measurements for links that are longer than 100 meter
D_Port support with HBA/Adapter from Qlogic and Emulex begins with FOS v7.3.0a. FOS v7.3.1a or earlier FOS
versions require the Fabric Vision license to support D_Port with 3rd party vendor HBAs. FOS v7.4.0 adds the
support for D_Port with 3rd party vendor HBAs with the combination of Fabric Watch license and Advanced
Performance Monitoring license. Please refer to Qlogic and Emulex documentation for specific adapter models
and firmware levels required.
Edge Hold Time
Edge Hold Time (EHT) default settings for FOS v7.x have changed from those in some FOS v6.4.x releases. The
following table shows the Default EHT value based on different FOS release levels originally installed at the
factory:
Factory Installed Version of FOS
Default EHT Value
FOS v7.X
220 ms
FOS v6.4.3x
500 ms
FOS v6.4.2x
500 ms
FOS v6.4.1x
220 ms
FOS v6.4.0x
500 ms
Any version prior to FOS v6.4.0
500 ms
Gen 5 platforms and blades are capable of setting an EHT value on an individual port basis. On 8G
platforms EHT is set on an ASIC-wide basis, meaning all ports on a common ASIC will have the same EHT
setting. Extra care should be given when configuring EHT on 8G platforms or Gen 5 platforms with 8G
blades to ensure E_Ports are configured with an appropriate Hold Time setting.
When using Virtual Fabrics and creating a new Logical Switch when running FOS v7.1.0 or later, the default
EHT setting for the new Logical Switch will be the FOS default value of 220ms. However, with FOS v7.1.0
and later, each Logical Switch can be configured with a unique EHT setting that is independent of other
Logical Switches and the Default Switch. Any Gen 5 ports (Condor3 based) assigned to that Logical Switch
Fabric OS 7.4.1d Release Notes v1.0
Page 35 of 160
will be configured with that Logical Switch’s EHT setting. Any 8G ports (Condor2 based) will continue to
share the EHT value configured for the Default Switch.
For more information on EHT behaviors and recommendations, refer to the Brocade SAN Fabric Resiliency
Best Practices v2.0 document available on www.brocade.com.
Encryption Behavior for the Brocade Encryption Switch (BES) and FS8-18
SafeNet’s KeySecure hosting NetApp’s LKM (SSKM) is supported for data encryption operations with SSKM
operating in PVM mode. Please see SSKM documentation for operating in PVM mode for details. Operation in
HVM mode is not supported
RASlog SPC-3005 with error 34 may be seen if the link key used by a BES/FS8-18 is re-established. Please
refer to the LKM/SSKM Encryption Admin Guide for the workaround. Also, please ensure that two (2) SSKM’s
are present in the deployment for workaround to be performed.
For crypto tape operations, please ensure to use Emulex FC HBA firmware/drivers 2.82A4/7.2.50.007 or
higher. Use of lower level firmware/drivers may result in hosts not being able to access their tape LUNs
through a crypto target container.
Adding of 3PAR Session/Enclosure LUNs to CTCs is now supported. Session/Enclosure LUNs (LUN 0xFE) used
by 3PAR InServ arrays must be added to CryptoTarget (CTC) containers with LUN state set to “cleartext”,
encryption policy set to “cleartext”. BES/FS8-18 will not perform any explicit enforcement of this requirement.
The Brocade Encryption switch and FS8-18 blade do not support QoS. When using encryption or Frame
Redirection, participating flows should not be included in QoS Zones.
The RSA DPM Appliance SW v3.2 is supported. The procedure for setting up the DPM Appliance with BES or a
DCX/DCX-4S/DCX 8510 with FS8-18 blades is located in the Encryption Admin Guide.
Support for registering a 2nd DPM Appliance on BES/FS8-18 is blocked. If the DPM Appliances are clustered,
then the virtual IP address hosted by a 3rd party IP load balancer for the DPM Cluster must be registered on
BES/FS8-18 in the primary slot for Key Vault IP.
With Windows and Veritas Volume Manager/Veritas Dynamic Multipathing, when LUN sizes less than 400MB
are presented to BES for encryption, a host panic may occur and this configuration is not supported in the FOS
v6.3.1 or later release.
Hot Code Load from FOS v7.3.x to FOS v7.4 is supported. Cryptographic operations and I/O will be disrupted
but other layer 2 FC traffic will not be disrupted.
When disk and tape CTCs are hosted on the same encryption engine, re-keying cannot be done while tape
backup or restore operations are running. Re-keying operations must be scheduled at a time that does not
conflict with normal tape I/O operations. The LUNs should not be configured with auto rekey option when
single EE has disk and tape CTCs.
Gatekeeper LUNs used by SYMAPI on the host for configuring SRDF/TF using in-band management must be
added to their containers with LUN state as “cleartext”, encryption policy as “cleartext” and without “-newLUN”
option.
BES/FS8-18 will reject the SCSI commands WRITE SAME, ATS(Compare and Write/Vendor Specific opcode
0xF1) and EXTENDED COPY, which are related to VAAI (vStorage APIs for Array Integration) hardware
acceleration in vSphere 4.1/5.x. This will result in non-VAAI methods of data transfer for the underlying arrays,
and may affect the performance of VM related operations.
VMware VMFS5 uses ATS commands with arrays that support ATS. BES/FS8-18 does not support this
command set. Use of a workaround procedure is required in order to configure encryption in a VMFS 5
environment. Please refer to Brocade Tech Note “Deployment Options for VMware VMFS-5 with Brocade
Encryption” for details.
XIV storage arrays that have been upgraded to firmware 11.2x or later required to support encryption on thin
provisioned LUNs will report all XIV data LUNs as TP=Yes.
FCIP (Brocade 7800 and FX8-24)
Any firmware activation will disrupt I/O traffic on FCIP links.
Latency measurements supported on FCIP Tunnels:1GbE & 10GbE - 200ms round trip time and 1% loss.
Fabric OS 7.4.1d Release Notes v1.0
Page 36 of 160
After inserting a 4G SFP in GE ports of an FX8-24 blade or 7800 switch, sometimes “sfpshow” output might
display “Cannot read serial data!”. Removing and re-inserting the SFP should resolve this issue. It is
recommended that users perform sfpshow immediately after inserting the SFP and ensure SFP is seated
properly before connecting the cables.
When running FOS v7.2.0 or later, if the new FCIP Circuit Group feature is configured on any FCIP Circuits, a
downgrade operation to pre-FOS v7.2.0 will be blocked until the feature is removed from the FCIP
configuration(s).
Under very rare conditions, FX8-24, 7800, and BES switches may set to faulty with code 2004c during
firmwaredownload or hareboot. This could be caused by internal communication link initialization failure after
a reset. The switch can be easily recovered by power cycling. Supportsave should be taken before power
cycling the switch to ensure the fault reason can be investigated by technical support providers.
Extension (Brocade 7840)
Brocade 7840 does not support FCIP connection to Brocade 7800 or FX8-24.
FOS v7.4 does not support 10G speed on the 24 16G FC ports on Brocade 7840.
FOS v7.4 does not support VEX port on Brocade 7840.
Running offline diagnostic tests results in FCIP tunnels down. Reboot the switch after offline diagnostic tests to
recover the tunnels.
Brocade 7840 supports Brocade 10 Gbps Tunable DWDM 80KM SFP+ optical transceiver. Following CLI
command can be used to configure the transceiver usage in Brocade 7840.
o portcfgge ge_num --set -channel <channel_num>
The channel number can have a value of 1 through 102. The detailed explanation of the values are
provided in the product data sheet at the following link:
http://www.brocade.com/downloads/documents/data_sheets/product_data_sheets/10gbe-tunabledwdm-80km-sfp-ds.pdf
When Brocade Network Advisor (BNA) v12.3.2 is used to download firmware on Brocade 7840, BNA reports
success of firmware download prematurely when 7840 has not reached High Availability state. Customers for
7840 using BNA to download firmware should wait for extra fifteen minutes after BNA reports success to
resume a work load.
Firmware downgrade from FOS v7.4 to FOS v7.3.0c or earlier should be avoided. Otherwise, the Brocade 7840
may become faulty. (Downgrading to FOS v7.3.0b5 can be used as a workaround.)
FOS v7.4 does not support HCL with IP Extension.
Fast deflate compression is supported only with FC traffics only, not with IP Extension.
IP fragmentation is not supported on the LAN side ports.
When running IPSec, it is recommended that both sides of the extension tunnel are running the same FOS
version.
When IP Extension traffic volume is high, the target device may back pressure the LAN interface of the Brocade
7840 via Ethernet pause. The target side 7840 will go into flow control. While the 7840 is under flow control, it
is possible that non-TCP frames destined for the target device will be dropped. TCP frames will be unaffected.
When the target device is a TS7720, this can cause the automated PINGs to be lost. This can result in an alert
raised by the local TS7720 indicating frame loss at the remote end. In these cases, the data load is unaffected
and this error should be ignored. This feature can be disabled on the TS7720.
FCoE/DCB/CEE (FCOE10-24)
When upgrading a DCX/DCX-4S with one or more FCOE10-24 blades from FOS v6.x to FOS v7.0.0 or later, the
user should carefully review Chapter 5 of the FOS v7.0.0 Converged Enhanced Ethernet Administrator’s Guide.
Ethernet L2 traffic with xSTP Hello timer set to less than or equal to 3 seconds may experience momentary
traffic disruption during HA failover.
Hot plugging a CP with firmware level less than FOS v6.3.0 into a DCX or DCX-4S with an active FCOE10-24
blade will result in the new standby CP not coming up.
Fabric OS 7.4.1d Release Notes v1.0
Page 37 of 160
When operating in Converged Mode, tagged traffic on the native VLAN of the switch interface is processed
normally. The host should be configured not to send VLAN tagged traffic on the switch’s native VLAN.
When operating in Converged Mode, tagged frames coming with a VLAN tag equal to the configured native
VLAN are dropped.
The Converged Network Adapter (CNA) may lose connectivity to the FCOE10-24 if the CNA interface is toggled
repeatedly over time. This issue is related to the CNA and rebooting the CNA restores connectivity.
The FCOE10-24 support only one CEE map on all interfaces connected to CNAs. Additionally, CEE map is not
recommended for use with non-FCoE traffic. QoS commands are recommended for interfaces carrying nonFCoE traffic.
Before upgrading to FOS v6.4.1_fcoe/v6.4.1_fcoe1/v7.0.0 or later, if the CEE map “default” value already
exists, the same “default” value is preserved after upgrading to FOS v6.4.1_fcoe/v6.4.1_fcoe1/v7.0.0 or later.
However, if the CEE map “default” is not configured before upgrading to FOS v6.4.1_fcoe/v6.4.1_fcoe1/v7.0.0
or later, then after upgrading to FOS v6.4.1_fcoe/v6.4.1_fcoe1/v7.0.0 or later, the following CEE map
“default” will be created automatically:
cee-map default
priority-group-table 1 weight 40 pfc
priority-group-table 2 weight 60
priority-table 2 2 2 1 2 2 2 2
When upgrading from FOS v6.3.x or v6.4.x to FOS v6.4.1_fcoe/v6.4.1_fcoe1/v7.0.0 or later, the CEE start up
configuration dcf.conf file will be incompatible with the FCoE provisioning changes implemented in v6.4.1_fcoe
and later releases. Users can save the dcf.conf file as a backup and apply it once the firmware upgrade is
completed to get the DCX/DCX-4S to the same startup configuration as in the older release.
It is recommended that Spanning Tree Protocol and its variants be disabled on CEE interfaces that are
connected to an FCoE device.
The Fabric Provided MAC Address (FPMA) and the Fibre Channel Identifier (FCID) assigned to a VN_Port cannot
be associated with any single front-end CEE port on which the FLOGI was received.
LLDP neighbor information may be released before the timer expires when DCBX is enabled on a CEE interface.
This occurs only when the CEE interface state changes from active to any other state. When the DCBX is not
enabled, the neighbor information is not released until the timer expires, irrespective of the interface state.
The FCoE login group name should be unique in a fabric-wide FCoE login management configuration. If there is
a login group name conflict, the merge logic would rename the login group by including the last three bytes of
the switch WWN in the login group name. As long as the OUI of the switch WWNs are identical this merge logic
guarantees uniqueness in any modified login group name (switches with the same OUI will have unique last 3
bytes in WWN). However, if the participating switches have different OUIs but identical last three bytes in the
switch WWNs, then the merge logic will fail to guarantee uniqueness of login group names. This will result in
one of the login groups being dropped from the configuration. This means, no device can login to the login
group that is dropped as a result of this name conflict. Users must create a new login group with a nonconflicting name to allow device logins.
Ethernet switch services must be explicitly enabled using the command “fosconfig –enable ethsw” before
powering on an FCOE10-24 blade. Failure to do so will cause the blade to be faulted (fault 9). Users can
enable ethsw after upgrading firmware without FC traffic interruption.
Upgrading firmware on a DCX or DCX-4S with one or more FCOE10-24 blades from FOS v6.4.1_fcoe1 to FOS
v7.0 or later will be non-disruptive to FCoE traffic through FCOE10-24 blades and FC traffic.
Upgrading firmware on a DCX or DCX-4S with one or more FCOE10-24 blades from FOS v6.3.x, v6.4.x, and
v6.4.1_fcoe to FOS v7.0 or later will be disruptive to any traffic through the FCOE10-24 blades.
When rebooting a DCX or DCX-4S with an FCOE10-24 blade, Qlogic CNA and LSAN zoning, the switch will
become very unresponsive for a period of time. This is due to the CNA sending excessive MS queries to the
switch.
The FCOE10-24 can handle 169 small FCoE frames in bursts. If you are using the FCOE10-24, and you delete
a large number of v-ports with HCM, some of the v-ports may not appear to be deleted. To correct this, disable
and re-enable FCoE with the following CLI commands:
Fabric OS 7.4.1d Release Notes v1.0
Page 38 of 160
switch:admin>fcoe –disable slot/port
switch:admin>fcoe --enable slot/port
When a FCOE10-24 blade is powered off during configuration replay, the interface specific configuration won’t
get applied. Later when FCOE10-24 blade is powered on, all physical interfaces will come up with default
configurations. User can execute “copy startup-config running-config” command to apply the new configuration
after powering on the FCOE10-24 blade.
When IGMP Snooping is disabled on a VLAN, all configured IGMP groups are removed from that VLAN. User
has to reconfigure the IGMP groups after enabling the IGMP snooping on that VLAN.
FOS v7.3 adds the support of FCOE10-24 blade in DCX 8510-8 chassis with following limitations:
o
Only one FCOE10-24 blade is supported at the fixed slot 1 position. Inserting the blade
into other slot positions, however, will not fault the blade.
o
An FCOE10-24 blade can co-exist with FC16-32 and FC8-32E blades only in a DCX 85108 chassis.
o
Only supports FCoE direct attach.
o
Layer2 Ethernet traffic is not supported.
o
If an FCoE10-24 blade is inserted into a DCX 8510-8 chassis, it is required to reboot the
chassis or slot poweroff/poweron core blades. A chassis reboot or slot poweroff/poweron
core blades must also be performed if the FCoE10-24 blade is removed and replaced
with another blade type.
FCR and Integrated Routing
With routing and dual backbone fabrics, the backbone fabric ID must be changed to keep the IDs unique.
VEX edge to VEX edge device sharing will not be supported.
The man page and help display of fcrlsanmatrix --display and fcrlsan --show command syntax should be
corrected as below:
fcrlsanmatrix --display -lsan | -fcr | -all
fcrlsan --show -enforce | -speed | -all
Forward Error Correction (FEC)
Though FEC capability is generally supported on Condor3 (16G capable FC) ports when operating at either 10G
or 16G speed, it is not supported with all DWDM links. Hence FEC may need to be disabled on Condor3 ports
when using DWDM links with some vendors by using portCfgFec command. Failure to disable FEC on these
DWDM links may result in link failure during port bring up. Refer to the Brocade Fabric OS 7.x Compatibility
Matrix for supported DWDM equipment and restrictions on FEC use.
To connect between a switch and an HBA at 16 Gbps, both sides must be in the same mode (fixed speed, and
FEC on or off) for them to communicate at that rate. If only one port has FEC enabled, neither port will be able
to see the other. If the ports are in dynamic mode, then they may connect, but not at 16 Gbps.
FICON
For FICON qualified releases, please refer to the Appendix: Additional Considerations for FICON Environments
section for details and notes on deployment in FICON environments. (This appendix is only included for
releases that have completed FICON qualification).
FL_Port (Loop) Support
FL_Port is not supported on FC16-32, FC16-48, FC16-64, FC8-32E, FC8-48E, Brocade 6510, Brocade 6505,
Brocade 6520, or Brocade 7840.
The FC8-48 and FC8-64 blade support attachment of loop devices.
Fabric OS 7.4.1d Release Notes v1.0
Page 39 of 160
Virtual Fabrics must be enabled on the chassis and loop devices may only be attached to ports on a 48-port or
64-port blade assigned to a non-Default Logical Switch operating with the default 10-bit addressing mode (they
may not be in the default Logical Switch).
A maximum of 144 ports may be used for connectivity to loop devices in a single Logical Switch within a
chassis in 10-bit dynamic area mode on DCX-4S.
A maximum of 112 ports may be used for connectivity to loop devices in a single Logical Switch within a
chassis in 10-bit dynamic area mode on DCX.
Loop devices continue to be supported when attached to ports on the FC8-16, FC8-32 with no new
restrictions.
Flow Vision
Users must not specify well known FC addresses, domain controller addresses or CUP Port ID (in FMS mode)
for either the source or the destination device field while defining flows.
Flow Vision does not support port swap. Users must not create flows on ports that are already swapped and
users must not swap the ports on which the flows are currently defined.
After a HA reboot, a flow generator flow can be created if the source or the destination port is F-Port. But traffic
will not be initiated. Toggling the port will enforce the restriction again to simulated ports.
Flow Monitor does not support flows with defined LUN parameters on ingress ports on 8G platforms.
Flow Generator traffic over VE port is supported only if no other traffic is running on any of the VE ports on that
blade or switch platform. If Flow Generator traffic is run over a VE port and production traffic is run over
another VE port, then the production traffic may be effected..
The all F-Port learning flow sys_mon_all_fport does not support fabric mode. In a chassis with virtual fabric
enabled, this flow can only be activated for a logical switch at a time.
ICLs on DCX/DCX-4S
If a DCX with an 8-link ICL license is connected to a DCX with a 16-link license, the DCX with the 16-link license
will report enc_out errors. The errors are harmless, but will continue to increment. These errors will not be
reported if a DCX with a 16-link license is connected to a DCX-4S with only 8-link ICL ports.
If ICL ports are disabled on only one side of an ICL link, the enabled side may see enc_out errors.
Port Initialization
Users may observe that a port is in “Port Throttled” state when an F_Port is being initialized. This is mostly an
informational message that is shown in switchshow output indicating systematic initialization of F_Ports.
However, a port may remain in “Port Throttled” state for an extended period of time and may never come
online if it fails to negotiate speed successfully with the neighboring port. Users are advised to check the speed
setting of the neighboring switch port to determine the cause of the speed negotiation failure.
Example Output:
74
9
10
36ed40
id
N8
In_Sync
FC Disabled (Port Throttled)
Port Mirroring
Port Mirroring is not supported on the Brocade 7800.
Virtual Fabrics
When creating Logical Fabrics that include switches that are not Virtual Fabrics capable, it is possible to have
two Logical Switches with different FIDs in the same fabric connected via a VF incapable switch. Extra caution
should be used to verify the FIDs match for all switches in the same Logical Fabric.
A switch with Virtual Fabrics enabled may not participate in a fabric that is using Password Database
distribution or Administrative Domains. The Virtual Fabrics feature must be disabled prior to deploying in a
fabric using these features.
Fabric OS 7.4.1d Release Notes v1.0
Page 40 of 160
ISL R_RDY mode is not supported in a base switch with FOS version 7.0 or higher.
WebTools
WebTools since FOS v7.1.0 has a “SupportSave” interface. It only collects, however, information specific to
WebTools. It does not contain the same information as collected by supportSave initiated through CLI or
Brocade Network Advisor.
When launching WebTools on a computer without Internet access, it could take up to 5 minutes to complete
because the certificate revocation check performed for the WebTools application takes time to timeout. Users
can turn off the certification revocation check on the Java control panel as a workaround.
FOS v7.4.0 is qualified and supported with Oracle Java version 7 update 76 and Java version 8 update 66.
Oracle enforces the latest JRE update to be used to launch WebTools. After JRE expiration date users will see
the message “Your Java version is out of date” when launching WebTools. Users can either ignore the message
by selecting the later option to proceed with launching WebTools, or install the latest JRE release and then
launch WebTools.
Zoning
There are limitations to zoning operations that can be performed from a FOS v6.x switch that is in the same
fabric as a FOS v7.0 or later switch if the FOS v6.x switch is not running the recommended firmware version.
Please see Fabric OS Interoperability section for details.
Peer zoning and target driven zoning should be used in a fabric with all switches running FOS v7.4 or later. If
peer zones have been created in a mixed fabric with switches running FOS v7.3 and FOS 7.4, peer zones
created with FOS 7.4 switch are distributed to FOS 7.3 switches. When the FOS v7.3 switches are upgraded to
FOS v7.4, traffic disruption may occur on these switches.
Read Diagnostics Parameters
RDP on FOS v7.4 is not compatible with RDP on FOS v7.3 switches. FOS v7.3 only supports the Read
Diagnostics Parameters (RDP) feature between Brocade switches both running FOS v7.3.
Link Cable Beaconing
The Link Cable Beaconing (LCB) feature on FOS v7.4 is not compatible with the implementation in FOS v7.3.0
– FOS v7.3.0c. LCB is only supported on ISLs between two Brocade switches both running FOS v7.3.0 – FOS
v7.3.0c, or both running FOS v7.3.1 or above.Support with third party vendor devices is only available with FOS
v7.3.1 or above with fix for defect 540720.
Brocade Analytics Monitoring Platform
vTap is only supported on Brocade Gen5 SAN products including: 6510, 6505, 6520, , DCX 8510-8, DCX
8510-4, 6545, 6546, 6547, 6548, M6505
vTap flows do not need to be deactivated when monitored switches are upgraded from FOS v7.4.0b to FOS
v7.4.1.
When a D_Port mode configuration mismatch between a fabric source switch and Analytics Monitoring
Platform leads to a segmented analytic switch link, the source switch will display the segmented AE_Port as a
segmented E_Port. This is tracked as defect 563489.
vTap and auto-discovered AF_Port do not support high availablility. In the event that a AF_port is re-discovered
by a fabric switch after a domain change on the attached Analytics Mointoring Platform and followed by an
hafailover or hareboot of the fabric switch, the remote AF_port information would be stale and vTap flows
cannot be activated. In this case, use one of the following workarounds:
o Manually configure the AF_Port after hafailover or hareboot
o Disable and then enable the AF_Port on the Analytics Monitoring Platform
o Deactivate vTap flow before firmware download, hafailover, or hareboot and activate vTap flow
again.
Fabric OS 7.4.1d Release Notes v1.0
Page 41 of 160
vTap and CS_CTL are mutually exclusive on a fabric switch. If CS_CTL is enabled on one port, the entire switch
cannot enble vTap. An F_Port trunk supporting CS_CTL must have all ports in the trunk group enabling CS_CTL.
Similary, in order to to enable vTap, all ports in an F_Port trunk must have CS_CTL disabled. In addition, the
master port of a trunk should remain the same between CS_CTL enable and disable. If this sequence is not
followed, vTap may remain active even after CS_CTL is enabled on an F_Port, or the error message “Disable
QoS zones error” may be observed when enabling vTap. A suggested method is to use the following sequence:
o When enabling CS_CTL mode, enable on all slave ports, followed by enabling on the master port,
noted as port M.
o When disabling CS_CTL mode, disable all active ports in the trunk, except the master port M.
Disable CS_CTL mode on port M. Enable all ports in the trunk followed by disabling CS_CTL mode
on the remaining ports.
When CS_CTL is enabled on a port without any connection, after reboot and disabling CS_CTL, vTap cannot be
enabled. The workaround is to enable the port as a SIM port after disabling CS_CTL, then toggle the port and
remove the SIM port configuration.
vTap and High QoS zone configuration is mutually exclusive on a fabric switch. vTap and Low QoS zone
configuration co-existence on a fabric switch is supported with FOS v7.4.1a or later.
vTap and in-flight encryption or compression compatibility is supported only on the following platforms with
FOS v7.4.1b or later: Brocade DCX8510-8/DCX8510-4 and 6520. On these supported platforms, the ports
with vTap enabled and ports with in-flight encryption or compression enabled must belong to different ASICs.
Please refer to the hardware installation guides of these platforms for port to ASIC mapping boundary..
Miscellaneous
Users must also keep the RADIUS accounting port (Authentication Port+1) open in the firewall to ensure proper
working of the RADIUS authentication.
Using a Windows anonymous FTP server for supportsave collection:
When using anonymous ftp, to avoid long delays or failure of simultaneous supportsave collections when AP
blades are present in a director chassis, the number of unlimited anonymous users for a Windows FTP server
should be configured as follows:
Number of anonymous FTP connections = (Number of director chassis) + (Number of installed Application
Blades x 3)
RASlog message AN-1010 may be seen occasionally indicating “Severe latency bottleneck detected”. Even
though it is a “Warning” message, it is likely to be a false alarm and can be ignored.
It is important to note that the outputs of slotshow –p and chassisShow commands also display the maximum
allowed power consumption per slot. These are absolute maximum values and should not be confused with the
real-time power consumption on 16G blades. The chassisshow command has a “Power Usage (Watts):” field
that shows the actual power consumed in real-time on 16G blades.
Class 3 frames that have been trapped to CPU will be discarded in the following scenarios on DCX/DCX4S/DCX 8510 during the following conditions:
HA failover on DCX/DCX-4S/DCX 8510 platforms while running FOS v7.0 or later firmware
Firmware upgrade from v7.0 to a later release on Brocade 300, 5100, VA-40FC, 5300, 6510
Firmware upgrade from v7.0.1 to a later release on Brocade 6505
Firmware upgrade from v7.1.0 to a later release on Brocade 6520
The QSFP information in the sfpShow output will indicate the ID field as all zeros. This is as designed.

It is recommended that for directors with more than 300 E_Ports, the switch be disabled prior to executing the
“switchCfgTrunk” command (used to disable or enable trunking on the switch).

During non-disruptive firmware upgrades, E_Ports in R-RDY mode may cause some frame drops on the E-port
links.
The Brocade Network Advisor seed switch should always have the highest FOS version used in the fabric.
For login authentication through RADIUS, Brocade switch should be able to reach RADIUS servers through TCP
authentication port (default 1812) and accounting port (default 1813). Both of these ports must be kept open
in any firewall settings.
When a firmware upgrade on a Brocade 6510 switch initiated through Brocade Network Advisor results with
“failed to enforce new iptable rules” error message, the switch could be inaccessible via SSH and/or Telnet.
Activating (from console) a new policy with the rules of the default active policy will restore access to the
switch.
The Location ID parameter under the configure CLI affects routing calculations, and should remain set to the
default value of 0 for normal use. Do not change the value unless explicitly instructed to do so by a Brocade
Support engineer.
Fabric OS Command Reference contains an error for the command creditRecovMode. The creditRecovMode -fe_crdloss configures time-out based credit loss detection of Condor-2 front-end ISL links. However, this
feature is NOT enabled by default.
Support for the 16G 2km ICL QSFP optics has the following notes:
o The maximum number of ICL ports with the 2km ICL QSFP can be supported in an 8510 backbone
switch with the two kilometer distance is 10, which requires 16 credits configured per Virtual
Channel. More ports can be supported with less distance and fewer credits. Full 16 ICL ports can
be supported with 11 credits configured per Virtual Channel for upto 1,375 meters.
o Before the ICL ports with the 2km ICL QSFP come online, switchShow CLI command may display
the port states as in-sync or shifting in and out of port fault.
o The sfpShow CLI command displays the 16G 2km ICL QSFP incorrectly as “Length Cu: 3 (units m)”
instead of the correct value 0.
o Firmware downgrade from FOS v7.3.1 to a prior version is blocked if ICL ports with 2km ICL QSFP
optics are present in the switch.
The maximum number of ports supported for slow drain device quarantine in the same zone with a slowdraining device port is 32. If the 32-port zone limit is exceeded, the quarantine action will not be taken. Once
the 32-port zone limit is reached, any new zoned device or port coming online will not be quarantined.
After firmware upgrade to FOS v7.4.0x, all audit event classes are enabled by default, even for the disabled
ones before firmware upgrade. Please run auditcfg again to disable events that should not be enabled.

Product: Brocade Fabric OS
Technology Group: Management
Reported In Release: FOS7.3.1
Technology: Fibre Channel Services
Symptom: Brocade switches hareboot due to Out of Memory (OOM) condition.
Condition: This is seen only on Brocade non-director switches (except Brocade BES, 7800 and 7840) running
FOS versions v7.2.1f, v7.3.1c or v7.4.1. This occurs due to OOM condition from a memory leak
during the periodic polling of digital diagnostic monitoring capable SFPs. Directors are not impacted.
Workaround: Monitor memory availability before performing any memory intensive operations such as
supportsave and perform hareboot as necessary. The switch does attempt autorecoery via hareboot
upon hitting a low memory threshold to recover f rom this condition without impacting traffic.
Recovery: No explicit recovery is required as the switch attempts a non disruptive autorecovery from the
memory loss, via hareboot, upon hitting a low memory threshold. However performing certain
operations such as supportsave while the system is in low memory state may lead to this Out of
Memory Panic of the switch and impact traffic.

messages are reported indicating that there was a FCIP DP core panic.
Condition: After using WTOOL to test FCIP connections between a pair of 7840s, if the listener side of WTOOL
connection is left active, there is a DP buffer leak issue that will cause the depletion of the DATA
buffer pool and eventual DP Panic (BLZ-5024).
Workaround: Terminate all WTOOL connection states after completing WTOOL testing on both ends of the
tested connections. Terminate both the initiator and the listener WTOOL connections when
completed using WTOOL.

Symptom:

Condition: This may be seen when a device on an NPIV port that has no zoning members (un-zoned device)
existing on the same NPIV port as other devices with zoning members defined. Zoning configuration
change (cfgsave or cfgenable) can lead to incorrect zoning enforcement on this port. Any non-NPIV
ports that also have no zoning definition (no members defined) will also be left in a state where these
un-zoned ports would be able to communicate with each other. No impact to ports that have zoning
defined. This can be seen in FOS v7.2.1d, v7.2.1e, v7.3.1, v7.3.1a, v7.4.0, v7.4.0a.
Workaround: NS queries will properly block access to viewing any other devices, but physical access could still
be allowed. To prevent any physical access, create a "dummy zone" for all ports that are currently
un-zoned (no zoning members defined).

Reported In Release: FOS6.4.3
Technology Area: Fabric Watch
Symptom: A E-port is fenced even after port fencing has been disabled.
Condition: This issue would only happen if E-port and port classes are configured with the same thresholds for
ST area. Disable port fence did not take care of the earlier fenced E-port properly under this
condition.
Workaround: Use the E-Port only threshold to monitor the State change of ISLs alone OR
to monitor all the ports in general, choose a different threshold value for E-port threshold and port
class threshold (probably E-Port threshold + 5 ).
Recovery: Bouncing the port

Condition: Topology: If there are any AP blades in the chassis, the BAD_OS errors may be seen after the
firmware upgrade completes and the MAPS rules monitoring these counters will get triggered.
Recovery: None of the blades in the switch, or VE ports in the AP blades get affected. So no recovery procedure
is needed when the problem is seen.

Product: FOS
Technology: Traffic Management
Reported In Release: FOS7.3.0
Technology Area: Lossless DLS
Symptom: Some parallel, equal cost paths may initially be unused for routing traffic to remote domains more
than one hop away. The paths may be utilized for traffic to intermediate domains along the path but
may be missing for a later domain. For those specific domains, the paths will not show up in any of
the reports or CLIs that show routing data for those specific domains. (Examples include
topologyShow, uRouteShow, director diagnostics for FICON, and others.)
When the problem corrects itself , the customer's traffic may experience re-routes as the switch adjust
routes to start using the previously missing paths. The correction of the problem to include the
missing paths happens automatically within a time window of 30 minutes from when the problem
happened. Many of cases where this happens should be corrected much sooner. When a re-route
occurs, out of order frames are always a possibility for mutli-hop routes. In this case, since the
reroutes happen at a later time than a cust
Condition: The switches must have Lossless DLS enabled. Then, the problem can happen when parallel paths to
an existing domain are added due to a new domain joining the fabric. For example: a diamond
topology where one of the points of diamond is offline and being brought back online.
Workaround: The switches will automatically correct the problem within 30 minutes.
If the customer wants to control when the reroute happens, they could bounce one of the missing
ISLs and this will cause FSPF to correct the problem. (Note: if the ISL is a trunk, all members of
the trunk must be bounced to generate the necessary events.)
Adding a new ISL that does not join an existing trunk group will also generates the necessary
events to fix the problem.

Technology Area: Platform Services
Symptom: When SVP sends the expansion commands, the BR6546 doesn't respond to the requests
intermittantly. The result is that some of the internal ports may not be properly enabled/disabled.
Condition: The issue happens when BR6546 is busy processing the previous request and can't respond to the new
ones. And the additional polling period is larger than the SVP's retry interval so it can't catch the retry
requests from SVP.
Workaround: The issue has been fixed by optimizing the polling mechanism and the request response routines
so that it won't miss the retries from SVP.
Recovery: Combined with the fix on IOSW, the issue can be recovered if SVP sents retry request at proper
intervals.

CVE-2014-3566
makes
it easier for man-in-the-middle attackers to obtain
Symptom:
cleartext data via a padding-oracle attack.
Condition: Following are the conditions that customers of Brocade SAN products could be exposed to this
vulnerability:
•
An end user must use a web browser to access the FOS WebTools interface or use other
HTTP clients such as Brocade Network Adviser to manage the switch.
•
A web browser or other HTTP client must support SSL protocol 3.0.
•
An intruder has to interject between an HTTP client and a SAN switch.
•
An intruder has to spend time monitoring the request-response formats to gain knowledge of
the system operations. Total of 256 SSL 3.0 requests are required to decrypt one byte of HTTP
cookies.
Workaround: End users should configure web browsers or Brocade Network Advisor to disable SSLv3 support
when accessing Brocade SAN switch. In addition, place Brocade SAN switch and other data
center critical infrastructure behind firewall to disallow access from the Internet to minimize
potential exposure to the attacks documented in this advisory.

Name
Server
(NS)
queue
full
condition
leads
to
NS out of sync with local/remote devices and the
Symptom:
device connectivity info will become inconsistent.
Condition: When a new switch, which is in AllAccess mode and has local attached deviced, joins a large fabric
consisting of a large number of devices (> 1000) and a large zone configuration (around 1MB)
enabled, there is a possibility that the customer may see NS queue full condition. This happens due to
Name Server discovery occurring before the existing fabric's zone configuration getting merged
across to the new switch.
Workaround: There are a couple workarounds for such a scenario and they are part of best-practices strategy for
large fabrics.
1. When connecting a new switch to a fabric, put it in NoAccess mode. This will avoid the
momentary transition to AllAccess and resultant RSCN storm to the fabric.
2. If connecting a new switch in AllAccess mode, take all devices connected to that switch offline
to prevent RSCN storm.
Recovery: Reboot the switch to recover from the error condition.

Technology Area: Security Vulnerability
Symptom: Bash shell security vulnerabilities (CVE-2014-6271, CVE-2014-7169, CVE-2014-7186, CVE-20147187). These vulnerabilities allow certain malformed function definition to bypass privilege
boundaries and execute unauthorized commands.
Condition: To exploit these vulnerabilities in FOS requires access to the CLI interface after user authentication
through console, Telnet, and SSH connections. An authenticated user account could exploit this bug
to gain privileges beyond the permission granted to this account, such as executing commands with
root privilege.
Workaround: Place switch and other data center critical infrastructure behind firewall to disallow access from
the Internet; Change all default account passwords; Delete guest accounts and temporary accounts
created for one-time usage needs; Utilize FOS password policy management to strengthen the
complexity, age, and history requirements of switch account passwords. Upgrading to a FOS
version including this fix prevents exposures to the four CVEs noted in the defect Symptom. In
addition, exposures to CVE-2014-6277 and CVE-2014-6278 are prevented.
