Using the Command-Line Interface
1
The command-line interface (CLI) is a text-based way to manage and monitor the system. You
can access the CLI by using a direct serial connection or by using a remote logical connection
with telnet or SSH.
This chapter describes the CLI syntax, conventions, and modes. It contains the following
sections:
•

Note: Firmware updates with new features and bug fixes are made
available from time to time at downloadcenter.netgear.com. Some
products can regularly check the site and download new firmware, or
you can check for and download new firmware manually. If the
features or behavior of your product does not match what is
described in this guide, you might need to update your firmware.

M4100 Series ProSAFE Managed Switches
Command Syntax
A command is one or more words that might be followed by one or more parameters.
Parameters can be required or optional values.
Some commands, such as show network and clear vlan, do not require parameters.
Other commands, such as network parms, require that you supply a value after the
command. You must type the parameter values in a specific order, and optional parameters
follow required parameters. The following example describes the network parms
command syntax:
Format
network parms <ipaddr> <netmask> [gateway]
•
network parms is the command name.
•
<ipaddr> and <netmask> are parameters and represent required values that you must
enter after you type the command keywords.
•
[gateway] is an optional keyword, so you are not required to enter a value in place of
the keyword.
This command line reference manual lists each command by the command name and
provides a brief description of the command. Each command reference also contains the
following information:
•
Format shows the command keywords and the required and optional parameters.
•
Mode identifies the command mode you must be in to access the command.
•
Default shows the default value, if any, of a configurable setting on the device.
The show commands also contain a description of the information that the command shows.
Command Conventions
In this document, the command name is in bold font. Parameters are in <italic font>
between angle brackets. You must replace the parameter name with an appropriate value,
which might be a name or number. Parameters are order-dependent. Keyword choices are in
bold font.
The parameters for a command might include mandatory values, optional values, or keyword
choices. The following table describes the conventions this document uses to distinguish
between value types.
Table 1. Parameter Conventions
Symbol
Example
Description
italic font in
angle brackets
<value> or [<value>]
Indicates a variable value. You must replace the
italicized text within angle brackets with a name or
number.
[ ] square brackets
[keyword]
Indicates an optional parameter.

Table 1. Parameter Conventions (continued)
Symbol
Example
Description
{ } curly braces
{choice1 | choice2}
Indicates that you must select a parameter from the
list of choices.
| Vertical bars
choice1 | choice2
Separates the mutually exclusive choices.
[{ }] Braces within
square brackets
[{choice1 | choice2}]
Indicates a choice within an optional element. This
format is used mainly for complicated commands
Common Parameter Values
Parameter values might be names (strings) or numbers. To use spaces as part of a name
parameter, enclose the name value in double quotes. For example, the expression “System
Name with Spaces” forces the system to accept the spaces. Empty strings (““) are not valid
user-defined strings. The following table describes common parameter values and value
formatting.
Table 2. Parameter Descriptions
Parameter
Description
ipaddr
This parameter is a valid IPv4 address. You can enter the IP address in the following
formats:
• a (32 bits)
• a.b (8.24 bits)
• a.b.c (8.8.16 bits)
• a.b.c.d (8.8.8.8)
In addition to these formats, the CLI accepts decimal, hexadecimal and octal formats
through the following input formats (where n is any valid hexadecimal, octal or decimal
number):
• 0xn (CLI assumes hexadecimal format.)
• 0n (CLI assumes octal format with leading zeros.)
• n (CLI assumes decimal format.)
ipv6-address
This parameter is a valid IPv6 address. You can enter the IP address in the following
formats:
• FE80:0000:0000:0000:020F:24FF:FEBF:DBCB
• FE80:0:0:0:20F:24FF:FEBF:DBCB
• FE80::20F24FF:FEBF:DBCB
• FE80:0:0:0:20F:24FF:128:141:49:32
For additional information, refer to RFC 3513.
Interface or
slot/port
Valid slot and port number separated by forward slashes. For example, 0/1 represents slot
number 0 and port number 1.
Logical Interface
Represents a logical slot and port number. This is applicable in the case of a port-channel
(LAG). You can use the logical slot/port to configure the port-channel.
Character strings
Use double quotation marks to identify character strings, for example, “System Name with
Spaces”. An empty string (“”) is not valid.
Using the Command-Line Interface

M4100 Series ProSAFE Managed Switches
Slot/Port Naming Convention
Managed switch software references physical entities such as cards and ports by using a
slot/port naming convention. The software also uses this convention to identify certain logical
entities, such as port-channel interfaces.
The slot number has two uses. In the case of physical ports, it identifies the card containing
the ports. In the case of logical and CPU ports it also identifies the type of interface or port.
Table 3. Type of slots
Slot Type
Description
Physical slot numbers
Physical slot numbers begin with zero, and are allocated up to the maximum
number of physical slots.
Logical slot numbers
Logical slots immediately follow physical slots and identify port-channel (LAG) or
router interfaces.
CPU slot numbers
The CPU slots immediately follow the logical slots.
The port identifies the specific physical port or logical interface being managed on a slot.
Table 4. Type of ports
Port Type
Description
Physical Ports
The physical ports for each slot are numbered sequentially starting from zero.

Port-channel or link aggregation group (LAG) interfaces are logical interfaces that
are only used for bridging functions.
VLAN routing interfaces are only used for routing functions.
Loopback interfaces are logical interfaces that are always up.
Tunnel interfaces are logical point-to-point links that carry encapsulated packets.
CPU ports
CPU ports are handled by the driver as one or more physical entities located on
physical slots.
Note: In the CLI, loopback and tunnel interfaces do not use the slot/port
format. To specify a loopback interface, you use the loopback ID. To
specify a tunnel interface, you use the tunnel ID.
Using a Command’s “No” Form
The no keyword is a specific form of an existing command and does not represent a new or
distinct command. Almost every configuration command has a no form. In general, use the
no form to reverse the action of a command or reset a value back to the default. For example,
the no shutdown configuration command reverses the shutdown of an interface. Use the
Using the Command-Line Interface

M4100 Series ProSAFE Managed Switches
command without the keyword no to reenable a disabled feature or to enable a feature that
is disabled by default. Only the configuration commands are available in the no form.
Managed Switch Modules
Managed switch software consists of flexible modules that can be applied in various
combinations to develop advanced Layer 2/3/4+ products. The commands and command
modes available on your switch depend on the installed modules. Additionally, for some
show commands, the output fields might change based on the modules included in the
software.
The software suite includes the following modules:
•
Switching (Layer 2)
•
Routing (Layer 3)
•
Quality of Service
•
Management (CLI, web UI, and SNMP)
Command Modes
The CLI groups commands into modes according to the command function. Each of the
command modes supports specific software commands. The commands in one mode are
not available until you switch to that particular mode, except for the User EXEC mode
commands. You can execute the User EXEC mode commands in the Privileged EXEC
mode.
The command prompt changes in each command mode to help you identify the current
mode. The following table describes the command modes and the prompts visible in that
mode.
Note: The command modes available on your switch depend on the software
modules that are installed. For example, a switch that does not support
BGPv4 does not provide the Router BGPv4 Command Mode.

Switch Port Commands
This section describes the commands used for switch port mode.
switchport mode
Use this command to configure the mode of a switch port as access, trunk, or general:
•
Trunk mode. In trunk mode, the port becomes a member of all VLANs on the switch
unless specified in the allowed list in the switchport trunk allowed vlan
command. The PVID of the port is set to the native VLAN as specified in the
switchport trunk native vlan command. This means that trunk ports accept both
tagged and untagged packets. Untagged packets are processed on the native VLAN and
tagged packets are processed on the VLAN for which the ID is contained in the packet.
MAC learning is performed on both tagged and untagged packets. Tagged packets that
are received with a VLAN ID of which the port is not a member are discarded and MAC
learning is not performed.
The trunk ports always transmit packets untagged on a native VLAN.
•
Access mode. In access mode, the port becomes a member of only one VLAN. The port
sends and receives untagged traffic. The port can also receive tagged traffic. Ingress
filtering is enabled on the port. This means that when the VLAN ID of a received packet is
not identical to the access VLAN ID, the packet is discarded.
•
General mode. In general mode, you can perform custom configuration of the VLAN
membership, PVID, tagging, ingress filtering, and so on. The general mode is legacy
behavior of the switch port configuration and you use legacy CLI commands to configure
the port in general mode.
Default

Double VLAN Commands
This section describes the commands you use to configure double VLAN (DVLAN). Double
VLAN tagging is a way to pass VLAN traffic from one customer domain to another through a
Metro Core in a simple and cost effective manner. The additional tag on the traffic helps
differentiate between customers in the MAN while preserving the VLAN identification of the
individual customers when they enter their own 802.1Q domain.
dvlan-tunnel ethertype
This command configures the ether-type for all interfaces. The ether-type may have the
values of 802.1Q, vman, or custom. If the ether-type has a value of custom, the optional

Voice VLAN Commands
This section describes the commands you use for Voice VLAN. Voice VLAN enables switch
ports to carry voice traffic with defined priority to enable separation of voice and data traffic
coming onto the port. The benefits of using Voice VLAN is to ensure that the sound quality of
an IP phone could be safeguarded from deteriorating when the data traffic on the port is high.
Also the inherent isolation provided by VLANs ensures that inter-VLAN traffic is under
management control and that network- attached clients cannot initiate a direct attack on
voice components. QoS-based on IEEE 802.1P Class of Service (CoS) uses classification
and scheduling to sent network traffic from the switch in a predictable manner. The system
uses the source MAC of the traffic traveling through the port to identify the IP phone data
flow.

Protected Ports Commands
This section describes commands you use to configure and view protected ports on a switch.
Protected ports do not forward traffic to each other, even if they are on the same VLAN.
However, protected ports can forward traffic to all unprotected ports in their group.
Unprotected ports can forward traffic to both protected and unprotected ports. Ports are
unprotected by default.
If an interface is configured as a protected port, and you add that interface to a Port Channel
or link aggregation group (LAG), the protected port status becomes operationally disabled on
the interface, and the interface follows the configuration of the LAG port. However, the
protected port configuration for the interface remains unchanged. Once the interface is no
longer a member of a LAG, the current configuration for that interface automatically becomes
effective.
switchport protected (Global Config)
Use this command to create a protected port group. The <groupid> parameter identifies the
set of protected ports. Use the name <name> pair to assign a name to the protected port
group. The name can be up to 32 alphanumeric characters long, including blanks. The

Private VLAN Commands
The Private VLANs feature separates a regular VLAN domain into two or more subdomains.
Each subdomain is defined (represented) by a primary VLAN and a secondary VLAN. The
primary VLAN ID is the same for all subdomains that belong to a private VLAN. The
secondary VLAN ID differentiates subdomains from each other and provides Layer 2 isolation
between ports of the same private VLAN. The types of VLANs within a private VLAN are as
follows:
•
Primary VLAN—Forwards the traffic from the promiscuous ports to isolated ports,
community ports, and other promiscuous ports in the same private VLAN. Only one
primary VLAN can be configured per private VLAN. All ports within a private VLAN share
primary VLAN.
•
Isolated VLAN—A secondary VLAN that carries traffic from isolated ports to promiscuous
ports. Only one isolated VLAN can be configured per private VLAN.
•
Community VLAN—A secondary VLAN that forwards traffic between ports that belong to
the same community and the promiscuous ports. There can be multiple community
VLANs per private VLAN.
Switching Commands
70
M4100 Series ProSAFE Managed Switches
Three types of port designations exist within a private VLAN:
•
Promiscuous Ports—An endpoint connected to a promiscuous port is allowed to
communicate with any endpoint within the private VLAN. Multiple promiscuous ports can
be defined for a single private VLAN domain.
•
Isolated Ports—An endpoint connected to an isolated port is allowed to communicate
with endpoints connected to promiscuous ports only. Endpoints connected to adjacent
isolated ports cannot communicate with each other.
•
Community Ports—An endpoint connected to a community port is allowed to
communicate with the endpoints within a community and with any configured
promiscuous port. The endpoints that belong to one community cannot communicate with
endpoints that belong to a different community or with endpoints connected to isolated
ports.
The Private VLANs can be extended across multiple switches through inter-switch/stack links
that transport primary, community, and isolated VLANs between devices.

GARP Commands
This section describes the commands you use to configure Generic Attribute Registration
Protocol (GARP) and view GARP status. The commands in this section affect both GARP
VLAN Registration Protocol (GVRP) and Garp Multicast Registration Protocol (GMRP).
GARP is a protocol that allows client stations to register with the switch for membership in
VLANS (by using GVMP) or multicast groups (by using GVMP).
set garp timer join
This command sets the GVRP join time for one port (Interface Config mode) or all (Global
Config mode) and per GARP. Join time is the interval between the transmission of GARP
Protocol Data Units (PDUs) registering (or re-registering) membership for a VLAN or
multicast group. This command has an effect only when GVRP is enabled. The time is from
10 to 100 (centiseconds). The value 20 centiseconds is 0.2 seconds.

set garp timer leave
This command sets the GVRP leave time for one port (Interface Config mode) or all ports
(Global Config mode) and only has an effect when GVRP is enabled. Leave time is the time
to wait after receiving a unregister request for a VLAN or a multicast group before deleting
the VLAN entry. This can be considered a buffer time for another station to assert registration
for the same attribute in order to maintain uninterrupted service. The leave time is 20–600
(centiseconds). The value 60 centiseconds is 0.6 seconds.

Storm-Control Commands
This section describes commands you use to configure storm control and view storm control
configuration information. A traffic storm is a condition that occurs when incoming packets
flood the LAN, which creates performance degradation in the network. The storm control
feature protects against this condition.
The switch provides broadcast, multicast, and unicast story recovery for individual interfaces.
Unicast storm control protects against traffic whose MAC addresses are not known by the
system. For broadcast, multicast, and unicast storm control, if the rate of traffic ingressing on
an interface increases beyond the configured threshold for that type, the traffic is dropped.
To configure storm control, you can enable the feature for all interfaces or for individual
interfaces, and you can set the threshold (storm-control level), beyond which the broadcast,
multicast, or unicast traffic is dropped. The storm control feature allows you to limit the rate of
specific types of packets through the switch on a per-port, per-type, basis.
Configuring a storm-control level also enables that form of storm control. Disabling a
storm-control level (using the no version of the command) sets the storm control level back to
the default value and disables that form of storm control. Using the no version of the
storm-control command (without stating a level) disables that form of storm control but
maintains the configured level (to be active the next time that form of storm control is
enabled.)
Note: The actual rate of ingress traffic required to activate storm control is
based on the size of incoming packets and the hard-coded average
packet size of 512 bytes—used to calculate a packet-per-second
(pps) rate—as the forwarding-plane requires pps versus an absolute
rate kbps. For example, if the configured limit is 10 percent, this is
converted to ~25000 pps, and this pps limit is set in forwarding plane
(hardware). You get the approximate desired output when 512 bytes
packets are used.

Flow Control Commands
In 802.3x flow control, the MAC control PAUSE operation is specified in IEEE 802.3 Annex
31 B. It allows traffic from one device to be throttled for a specified period of time and is
defined for devices that are directly connected. A device that needs to inhibit transmission of
data frames from another device on the LAN transmits a PAUSE frame as defined in the
IEEE specification.
This feature allows the user to configure the switch to use symmetric, asymmetric, or no flow
control. Asymmetric flow control allows the switch to respond to received PAUSE frames, but
the port cannot generate PAUSE frames. Symmetric flow control allows the switch to both
respond to and generate MAC control PAUSE frames.
flowcontrol
Use this command to enable or disable the symmetric or asymmetric flow control on the
switch. Use the no form of command to disable the symmetric or asymmetric flow control.
Asymmetric here means that Tx Pause can never be enabled. Only Rx Pause can be
enabled.

Port-Channel/LAG (802.3ad) Commands
This section describes the commands you use to configure port-channels, which are also
known as link aggregation groups (LAGs). Link aggregation allows you to combine multiple
full-duplex Ethernet links into a single logical link. Network devices treat the aggregation as if
it were a single link, which increases fault tolerance and provides load sharing. The LAG
feature initially load shares traffic based upon the source and destination MAC address.
Assign the port-channel (LAG) VLAN membership after you create a port-channel. If you do
not assign VLAN membership, the port-channel might become a member of the
management VLAN which can result in learning and switching issues.
A port-channel (LAG) interface can be either static or dynamic, but not both. All members of a
port channel must participate in the same protocols.) A static port-channel interface does not
require a partner system to be able to aggregate its member ports.
Note: If you configure the maximum number of dynamic port-channels
(LAGs) that your platform supports, additional port-channels that you
configure are automatically static.
addport
This command adds one port to the port-channel (LAG). The interface is a logical slot/port
number or a group ID of a configured port-channel.
Note: Before adding a port to a port-channel, set the physical mode of the
port. For more information, see speed on page 22.

port-channel load-balance
This command selects the load-balancing option used on a port-channel (LAG). Traffic is
balanced on a port-channel (LAG) by selecting one of the links in the channel over which to
transmit specific packets. The link is selected by creating a binary pattern from selected fields
in a packet, and associating that pattern with a particular link.
Load-balancing is not supported on every device. The range of options for load-balancing
can vary per device. The switch also supports enhanced hashing mode, which has the
following advantages:
•
MODULO-N (where N is the number of active link members in a LAG) operation based on
the number of ports in the LAG.
•
Packet attributes selection based on the packet type: For L2 packets, source and
destination MAC address are used for hash computation. For L3 packets, source IP,
destination IP address, TCP/UDP ports are used.
•
Non-Unicast traffic and unicast traffic is hashed using a common hash algorithm
•
Excellent load balancing performance.
The interface is a logical <slot/port> for a configured port-channel. The option all

Port Mirroring Commands
Port mirroring, which is also known as port monitoring, selects network traffic that you can
analyze with a network analyzer, such as a SwitchProbe device or other Remote Monitoring
(RMON) probe.
monitor session
This command configures a probe port and a monitored port for monitor session (port
monitoring). Use the source interface <slot/port> parameter to specify the interface
to monitor. Use rx to monitor only ingress packets or use tx to monitor only egress packets.
If you do not specify an rx or tx option, the destination port monitors both ingress and
egress packets.
Switching Commands
125
M4100 Series ProSAFE Managed Switches
A VLAN can be configured as the source to a session (all member ports of that VLAN are
monitored). Remote port mirroring is configured by adding the RSPAN VLAN ID. At the
source switch, the destination is configured as the RSPAN VLAN and at the destination
switch, the source is configured as the RSPAN VLAN.
Note: The source and destination cannot be configured as remote on the
same device.
The reflector-port is configured at the source switch. The reflector-port forwards the mirrored
traffic towards the destination switch.
Note: This port must be configured with RSPAN VLAN membership.
IP/MAC ACL can be attached to a session by giving the access list number/name.
Use the destination interface <slot/port> to specify the interface to receive the
monitored traffic.
Use the mode parameter to enable the administrative mode of the session. If enabled, the
probe port monitors all the traffic received and transmitted on the physical monitored port.
Use the filter parameter to filter a specified access group either by IP address or MAC
address.

Static MAC Filtering Commands
The commands in this section describe how to configure static MAC filtering. Static MAC
filtering allows you to configure destination ports for a static multicast MAC filter irrespective
of the platform.
macfilter
This command adds a static MAC filter entry for the MAC address <macaddr> on the VLAN
<vlanid>. A packet with a specific destination MAC address in a specific VLAN is admitted
only if the ingress port is defined in the set of source ports, otherwise the packet is dropped.
On the egress side, a packet that was admitted is sent through all ports that are defined in
the set of destination ports.
The value of the <macaddr> parameter is a 6-byte hexadecimal number in the format of
b1:b2:b3:b4:b5:b6. The following MAC addresses are restricted: 00:00:00:00:00:00,
01:80:C2:00:00:00 to 01:80:C2:00:00:0F, 01:80:C2:00:00:20 to 01:80:C2:00:00:21, and
FF:FF:FF:FF:FF:FF. The <vlanid> parameter must identify a valid VLAN.
The number of static mac filters supported on the system is different for MAC filters where
source ports are configured and MAC filters where destination ports are configured.
•
For unicast MAC address filters and multicast MAC address filters with source port lists,
the maximum number of static MAC filters supported is 20.
•
For multicast MAC address filters with destination ports configured, the maximum number
of static filters supported is 256.
For example, for current platforms you can configure the following combinations:
•
Unicast MAC and source port (max = 20)
•
Multicast MAC and source port (max=20)
•
Multicast MAC and destination port (only) (max=256)
•
Multicast MAC and source ports and destination ports (max=20)

Dynamic ARP Inspection Commands
Dynamic ARP Inspection (DAI) is a security feature that rejects invalid and malicious ARP
packets. DAI prevents a class of man-in-the-middle attacks, where an unfriendly station
intercepts traffic for other stations by poisoning the ARP caches of its unsuspecting
neighbors. The miscreant sends ARP requests or responses mapping another station’s IP
address to its own MAC address.
DAI relies on DHCP snooping. DHCP snooping listens to DHCP message exchanges and
builds a binding database of valid (MAC address, IP address, VLAN, and interface) tuples.
When DAI is enabled, the switch drops ARP packets whose sender MAC address and
sender IP address do not match an entry in the DHCP snooping bindings database. You can
optionally configure additional ARP packet validation.

IGMP Snooping Configuration Commands
This section describes the commands you use to configure IGMP snooping. The software
supports IGMP Versions 1, 2, and 3. The IGMP snooping feature can help conserve
bandwidth because it allows the switch to forward IP multicast traffic only to connected hosts
that request multicast traffic. IGMPv3 adds source filtering capabilities to IGMP versions 1
and 2.
Switching Commands
154
M4100 Series ProSAFE Managed Switches
set igmp
This command enables IGMP Snooping on the system (Global Config Mode) or an interface
(Interface Config Mode). This command also enables IGMP snooping on a particular VLAN
(VLAN Config Mode) and can enable IGMP snooping on all interfaces participating in a
VLAN.
If an interface has IGMP Snooping enabled and you enable this interface for routing or enlist
it as a member of a port-channel (LAG), IGMP Snooping functionality is disabled on that
interface. IGMP Snooping functionality is re-enabled if you disable routing or remove
port-channel (LAG) membership from an interface that has IGMP Snooping enabled.
The IGMP application supports the following activities:
•
Validation of the IP header checksum (as well as the IGMP header checksum) and
discarding of the frame upon checksum error.
•
Maintenance of the forwarding table entries based on the MAC address versus the IP
address.
•
Flooding of unregistered multicast data packets to all ports in the VLAN.

set igmp fast-leave
This command enables or disables IGMP Snooping fast-leave admin mode on a selected
interface or VLAN. Enabling fast-leave allows the switch to immediately remove the layer 2
LAN interface from its forwarding table entry upon receiving an IGMP leave message for that
multicast group without first sending out MAC-based general queries to the interface.
You should enable fast-leave admin mode only on VLANs where only one host is connected
to each layer 2 LAN port. This prevents the inadvertent dropping of the other hosts that were
connected to the same layer 2 LAN port but were still interested in receiving multicast traffic
directed to that group. Also, fast-leave processing is supported only with IGMP version 2
hosts.

IGMP Snooping Querier Commands
IGMP Snooping requires that one central switch or router periodically query all end-devices
on the network to announce their multicast memberships. This central device is the “IGMP
Querier”. The IGMP query responses, known as IGMP reports, keep the switch updated with
the current multicast group membership on a port-by-port basis. If the switch does not
receive updated membership information in a timely fashion, it will stop forwarding multicast
to the port where the end device is located.
This section describes commands used to configure and display information about IGMP
Snooping Queriers on the network and, separately, on VLANs.
set igmp querier
Use this command to enable IGMP Snooping Querier on the system, using Global Config
mode, or on a VLAN. Using this command, you can specify the IP Address that the Snooping
Querier switch should use as the source address while generating periodic queries.
If a VLAN has IGMP Snooping Querier enabled and IGMP Snooping is operationally disabled
on it, IGMP Snooping Querier functionality is disabled on that VLAN. IGMP Snooping
functionality is re-enabled if IGMP Snooping is operational on the VLAN.
Note: The Querier IP Address assigned for a VLAN takes preference over
global configuration.
The IGMP Snooping Querier application supports sending periodic general queries on the
VLAN to solicit membership reports.

MLD Snooping Commands
This section describes commands used for MLD Snooping. In IPv4, Layer 2 switches can use
IGMP Snooping to limit the flooding of multicast traffic by dynamically configuring Layer 2
interfaces so that multicast traffic is forwarded only to those interfaces associated with IP
multicast addresses. In IPv6, MLD Snooping performs a similar function. With MLD
Snooping, IPv6 multicast data is selectively forwarded to a list of ports that want to receive
the data, instead of being flooded to all ports in a VLAN. This list is constructed by snooping
IPv6 multicast control packets.
set mld
Use this command to enable MLD Snooping on the system (Global Config Mode) or an
interface (Interface Config Mode). This command also enables MLD Snooping on a particular
VLAN and enables MLD Snooping on all interfaces participating in a VLAN.
If an interface has MLD Snooping enabled and you enable this interface for routing or enlist it
as a member of a port-channel (LAG), MLD Snooping functionality is disabled on that
interface. MLD Snooping functionality is re-enabled if you disable routing or remove port
channel (LAG) membership from an interface that has MLD Snooping enabled.
MLD Snooping supports the following activities:
•
Validation of address version, payload length consistencies and discarding of the frame
upon error.
•
Maintenance of the forwarding table entries based on the MAC address versus the IPv6
address.
•
Flooding of unregistered multicast data packets to all ports in the VLAN.

set mld fast-leave
Use this command to enable MLD Snooping fast-leave admin mode on a selected interface
or VLAN. Enabling fast-leave allows the switch to immediately remove the Layer 2 LAN
interface from its forwarding table entry upon receiving and MLD done message for that
multicast group without first sending out MAC-based general queries to the interface.
Note: You should enable fast-leave admin mode only on VLANs where only
one host is connected to each Layer 2 LAN port. This prevents the
inadvertent dropping of the other hosts that were connected to the
same layer 2 LAN port but were still interested in receiving multicast
traffic directed to that group.

MLD Snooping Querier Commands
In an IPv6 environment, MLD Snooping requires that one central switch or router periodically
query all end-devices on the network to announce their multicast memberships. This central
device is the MLD Querier. The MLD query responses, known as MLD reports, keep the
switch updated with the current multicast group membership on a port-by-port basis. If the
switch does not receive updated membership information in a timely fashion, it will stop
forwarding multicast frames to the port where the end device is located.
This section describes the commands you use to configure and display information on MLD
Snooping queries on the network and, separately, on VLANs.
set mld querier
Use this command to enable MLD Snooping Querier on the system (Global Config Mode) or
on a VLAN. Using this command, you can specify the IP address that the snooping querier
switch should use as a source address while generating periodic queries.
If a VLAN has MLD Snooping Querier enabled and MLD Snooping is operationally disabled
on it, MLD Snooping Querier functionality is disabled on that VLAN. MLD Snooping
functionality is re-enabled if MLD Snooping is operational on the VLAN.
The MLD Snooping Querier sends periodic general queries on the VLAN to solicit
membership reports.

About MVR
Internet Group Management Protocol (IGMP) Layer 3 is widely used for IPv4 network
multicasting. In Layer 2 networks, IGMP uses resources inefficiently. For example, a Layer 2
switch sends multicast frames to all ports, even if there are receivers connected to only a few
ports.
To address this problem, the IGMP Snooping protocol was developed. The problem still
appears, though, when receivers are in different VLANs.
Multicast VLAN registration (MVR) is intended to solve the problem of receivers in different
VLANs. It uses a dedicated manually configured VLAN, called the multicast VLAN, to forward
multicast traffic over a Layer 2 network with IGMP snooping.

Mode
Global Config
mvr mode
This command changes the MVR mode type. If the mode is set to compatible, the switch
does not learn multicast groups; they need to be configured by the operator as the protocol
does not forward joins from the hosts to the router. To operate in this mode, the IGMP router
needs to be statically configured to transmit all required multicast streams to the MVR switch.
If the mode is set to dynamic, the switch learns existing multicast groups by snooping the
IGMP queries from router on source ports and forwarding the IGMP joins from the hosts to
the IGMP router on the multicast VLAN (with appropriate translation of the VLAN ID).

mvr immediate
This command enables MVR immediate leave mode. MVR has two modes of operating with
the IGMP Leave messages: normal leave and immediate leave:
•
In normal leave mode, when a leave is received, the general IGMP query is sent from a
Layer 2 switch to the receiver port, where the leave was received. Then reports are
received from other interested hosts that are also connected to that port, for example,
using hub.
•
In immediate leave mode, when a leave is received, the switch is immediately
reconfigured not to forward a specific multicast stream to the port where a message is
received. This mode is used only for ports where only one client might be connected.
Default
Disabled

This command configures an IP address on an interface. You can also use this command to
configure one or more secondary IP addresses on the interface. The command supports
RFC 3021 and accepts using 31-bit prefixes on IPv4 point-to-point links. This command adds
the label IP address in show ip interface.
Routing Commands
234
M4100 Series ProSAFE Managed Switches
Note: The 31-bit subnet mask is only supported on routing interface. This
feature is not supported on a network port because it acts as a host,
not a router, on the management interface.
Format
ip address <ipaddr> {<subnetmask> | /<prefix-length>} [secondary]
Mode
Interface Config
Parameter
Description
<ipaddr>
The IP address of the interface.
<subnetmask>
A four-digit dotted-decimal number that represents the subnet mask of the interface
<prefix-length>
Implements RFC 3021. Using the / notation of the subnet mask, this is an integer
that indicates the length of the subnet mask. Range is 5–32 bits.
no ip address
This command deletes an IP address from an interface. The value for <ipaddr> is the IP
address of the interface in a.b.c.d format where the range for a, b, c, and d is 1-255. The
value for <subnetmask> is a 4-digit dotted-decimal number which represents the subnet
mask of the interface. To remove all of the IP addresses (primary and secondary) configured
on the interface, enter the command no ip address.

ip route
This command configures a static route. The <ipaddr> parameter is a valid IP address,
and <subnetmask> is a valid subnet mask. The <nexthopip> parameter is a valid IP
address of the next hop router. Specifying Null0 as nexthop parameter adds a static reject
route. The optional <preference> parameter is an integer (value from 1 to 255) that allows
you to specify the preference value (sometimes called “administrative distance”) of an
individual static route. Among routes to the same destination, the route with the lowest
preference value is the route entered into the forwarding database. By specifying the
preference of a static route, you control whether a static route is more or less preferred than
routes from dynamic routing protocols. The preference also controls whether a static route is
more or less preferred than other static routes to the same destination. A route with a
preference of 255 cannot be used to forward traffic.
For the static routes to be visible, you must perform the following steps:
•
Enable IP routing globally.
•
Enable IP routing for the interface.
•
Confirm that the associated link is also up

ip route distance
This command sets the default distance (preference) for static routes. Lower route distance
values are preferred when determining the best route. The ip route and ip route
default commands allow you to optionally set the distance (preference) of an individual
static route. The default distance is used when no distance is specified in these commands.
Changing the default distance does not update the distance of existing static routes, even if
they were assigned the original default distance. The new default distance will only be
applied to static routes created after invoking the ip route distance command.

ip mtu
This command sets the IP maximum transmission unit (MTU) on a routing interface. The IP
MTU is the size of the largest IP packet that can be transmitted on the interface without
fragmentation. The software currently does not fragment IP packets.
•
Packets forwarded in hardware ignore the IP MTU.
•
Packets forwarded in software are dropped if they exceed the IP MTU of the outgoing
interface.
Packets originated on the router, such as OSPF packets, might be fragmented by the IP
stack. The IP stack uses its default IP MTU and ignores the value set using the ip mtu
command.
Routing Commands
239
M4100 Series ProSAFE Managed Switches
OSPF advertises the IP MTU in the Database Description packets it sends to its neighbors
during database exchange. If two OSPF neighbors advertise different IP MTUs, they will not
form an adjacency. (unless OSPF has been instructed to ignore differences in IP MTU with
the ip ospf mtu-ignore command.)
Note: The IP MTU size refers to the maximum size of the IP packet (IP
Header + IP payload). It does not include any extra bytes that might
be required for Layer-2 headers. To receive and process packets, the
Ethernet MTU must take into account the size of the Ethernet header.

show ip route
This command displays the routing table. The <ip-address> specifies the network for
which the route is to be displayed and displays the best matching best-route for the address.
The <mask> specifies the subnet mask for the <ip-address>. When you use the
longer-prefixes keyword, the <ip-address> and <mask> pair becomes the prefix, and
the command displays the routes to the addresses that match that prefix. Use the
<protocol> parameter to specify the protocol that installed the routes. The value for
<protocol> can be connected, ospf, rip, or static. Use the all parameter to display
all routes including best and non-best routes. If you do not use the all parameter, the
command only displays the best route.
A “T” flag appended to a route indicates that it is an ECMP route, but only one of its next hops
has been installed in the forwarding table. The forwarding table might limit the number of
ECMP routes or the number of ECMP groups. When an ECMP route cannot be installed
because such a limit is reached, the route is installed with a single next hop. Such truncated
routes can be identified by a “T” after the interface name.

The administrative distance associated with this route. Routes with low values are
preferred over routes with higher values.
Metric
The cost associated with this route.
via Next-Hop
The outgoing router IP address to use when forwarding traffic to the next router (if any)
in the path toward the destination.
Route-Timestamp
The last updated time for dynamic routes. The format of Route-Timestamp will be
• Days:Hours:Minutes if days > = 1
• Hours:Minutes:Seconds if days < 1
Interface
The outgoing router interface to use when forwarding traffic to the next destination. For
reject routes, the next hop interface would be Null0 interface.
To administratively control the traffic destined to a particular network and prevent it from
being forwarded through the router, you can configure a static reject route on the router. Such
traffic would be discarded and the ICMP destination unreachable message is sent back to the
source. This is typically used for preventing routing loops. The reject route added in the RTO
is of the type OSPF Inter-Area. Reject routes (routes of REJECT type installed by any
protocol) are not redistributed by OSPF/RIP. Reject routes are supported in both OSPFv2
and OSPFv3.

show ip route summary
Use this command to display the routing table summary. Use the optional all parameter to
show the number of all routes, including best and non-best routes. To include only the
number of best routes, do not use the optional parameter.
If you enter the optional all keyword, some statistics, such as the number of routes from
each source, include counts for alternate routes. An alternate route is a route that is not the
most preferred route to its destination and therefore is not installed in the forwarding table.
If you do not enter the optional all keyword, the output reports only the best routes.

ip helper-address (Global Config)
Use the Global Configuration ip helper-address command to have the switch forward
User Datagram Protocol (UDP) broadcasts received on an interface. To disable the
forwarding of broadcast packets to specific addresses, use the no form of this command.
The ip helper-address command forwards specific UDP broadcast from one interface to
another. You can define many helper addresses but the total number of address-port pairs is
limited to 128 for the whole device. The setting of a helper address for a specific interface has
precedence over a setting of a helper address for all interfaces.
•
<ip-address> is the destination broadcast or host address to be used when forwarding
UDP broadcasts. You can specify 0.0.0.0 to indicate not to forward the UDP packet to
any host and enter 255.255.255.255 to broadcast the UDP packets to all hosts on the
target subnet.
•
<dest-udp-port> is the broadcast packet destination UDP port number to forward. If
not specified, packets for the default services are forwarded to the helper address. The
valid range is 0-65535.
Default
No helper addresses are configured.
Format
ip helper-address <ip-address> [<dest-udp-port> | dhcp | domain |

packets are sent. The IP address cannot be an IP address configured on any
interface of the local router.
<dest-udp-port>
A destination UDP port number from 0 to 65535.
port name options
The destination UDP port may be optionally specified by its name. Whether a port is
specified by its number or its name has no effect on behavior. The names
recognized are as follows:
• dhcp (port 67)

Differentiated Services (DiffServ) Commands
This section describes the commands you use to configure QOS Differentiated Services
(DiffServ).
You configure DiffServ in several stages by specifying three DiffServ components:
1. Class
a. Creating and deleting classes.
b. Defining match criteria for a class.
Quality of Service Commands
270
M4100 Series ProSAFE Managed Switches
2. Policy
a. Creating and deleting policies
b. Associating classes with a policy
c. Defining policy statements for a policy/class combination
3. Service
a. Adding and removing a policy to/from an inbound or outbound interface
The DiffServ class defines the packet filtering criteria. The attributes of a DiffServ policy
define the way the switch processes packets. You can define policy attributes on a per-class
instance basis. The switch applies these attributes when a match occurs.
Packet processing begins when the switch tests the match criteria for a packet. The switch
applies a policy to a packet when it finds a class match within that policy.
The following rules apply when you create a DiffServ class:
•
Each class can contain a maximum of one referenced (nested) class
•
Class definitions do not support hierarchical service policies
A class definition can contain a maximum of one reference to another class. You can
combine the reference with other match criteria. The referenced class is truly a reference and
not a copy, because additions to a referenced class affect all classes that reference it.
Changes to any class definition currently referenced by any other class must result in valid
class definitions for all derived classes, otherwise the switch rejects the change. You can
remove a class reference from a class definition.
The only way to remove an individual match criterion from an existing class definition is to
delete the class and re-create it.
Note: The mark possibilities for policing include CoS, IP DSCP, and IP
Precedence. While the latter two are only meaningful for IP packet
types, CoS marking is allowed for both IP and non-IP packets, since it
updates the 802.1p user priority field contained in the VLAN tag of the
layer 2 packet header.

DiffServ Class Commands
Use the DiffServ class commands to define traffic classification. To classify traffic, you specify
Behavior Aggregate (BA), based on DSCP and Multi-Field (MF) classes of traffic (name,
match criteria)
This set of commands consists of class creation/deletion and matching, with the class match
commands specifying Layer 3, Layer 2, and general match criteria. The class match criteria
are also known as class rules, with a class definition consisting of one or more rules to
identify the traffic that belongs to the class.
Note: Once you create a class match criterion for a class, you cannot
change or delete the criterion. To change or delete a class match
criterion, you must delete and re-create the entire class.
The CLI command root is class-map.
class-map
This command defines a DiffServ class of type match-all. When used without any match
condition, this command enters the class-map mode. The <class-map-name> is a
case-sensitive alphanumeric string from 1 to 31 characters uniquely identifying an existing
DiffServ class.
Note: The class-map-name “default” is reserved and you must not use it.
The class type of match-all indicates all of the individual match conditions must be true for
a packet to be considered a member of the class. This command might be used without
specifying a class type to enter the Class-Map Config mode for an existing DiffServ class.

DiffServ Policy Commands
Use the DiffServ policy commands to specify traffic conditioning actions, such as policing and
marking, to apply to traffic classes
Use the policy commands to associate a traffic class that you define by using the class
command set with one or more QoS policy attributes. Assign the class/policy association to
an interface to form a service. Specify the policy name when you create the policy.
Each traffic class defines a particular treatment for packets that match the class definition.
You can associate multiple traffic classes with a single policy. When a packet satisfies the
conditions of more than one class, preference is based on the order in which you add the
classes to the policy. The first class you add has the highest precedence.
This set of commands consists of policy creation/deletion, class addition/removal, and
individual policy attributes.

police-simple
This command is used to establish the traffic policing style for the specified class. The simple
form of the police command uses a single data rate and burst size, resulting in two outcomes:
conform and violate. The conforming data rate is specified in kilobits-per-second (Kbps) and
is an integer from 1 to 4294967295. The conforming burst size is specified in kilobytes (KB)
and is an integer from 1 to 128.
For each outcome, the only possible actions are drop, set-cos-transmit, set-dscp-transmit,
set-prec-transmit, or transmit. In this simple form of the police command, the conform action
defaults to transmit and the violate action defaults to drop.
For set-cos-transmit, an 802.1p priority value is required and is specified as an integer
from 0-7.
For set-dscp-transmit, a <dscpval> value is required and is specified as either an
integer from 0 to 63, or symbolically through one of the following keywords: af11, af12,
af13, af21, af22, af23, af31, af32, af33, af41, af42, af43, be, cs0, cs1, cs2, cs3,
cs4, cs5, cs6, cs7, or ef.
For set-prec-transmit, an IP Precedence value is required and is specified as an
integer from 0-7.

MAC Access Control List (ACL) Commands
This section describes the commands you use to configure MAC ACL settings. MAC ACLs
ensure that only authorized users have access to specific resources and block any
unwarranted attempts to reach network resources.
The following rules apply to MAC ACLs:
•
The maximum number of ACLs you can create is hardware-dependent. The limit applies
to all ACLs, regardless of type.
•
The system supports only Ethernet II frame types.
•
The maximum number of rules per MAC ACL is hardware-dependent.
mac access-list extended
This command creates a MAC access control list (ACL) identified by <name>, consisting of
classification fields defined for the Layer 2 header of an Ethernet frame. The <name>
parameter is a case-sensitive alphanumeric string from 1 to 31 characters uniquely
identifying the MAC access list.
If a MAC ACL by this name exists, this command enters Mac-Access-List config mode to
allow updating the existing MAC ACL.

{deny | permit} (MAC ACL)
This command creates a new rule for the current MAC access list. Each rule is appended to
the list of configured rules for the list.
Note: The no form of this command is not supported, since the rules within a
MAC ACL cannot be deleted individually. Rather, the entire MAC ACL
must be deleted and respecified.
Note: An implicit deny all MAC rule always terminates the access list.
A rule might either deny or permit traffic according to the specified classification fields. At a
minimum, the source and destination MAC value must be specified, each of which might be
substituted using the keyword any to indicate a match on any value in that field. The
remaining command parameters are all optional, but the most frequently used parameters
appear in the same relative order as shown in the command format.
The Ethertype might be specified as either a keyword or a four-digit hexadecimal value from
0x0600-0xFFFF. The currently supported <ethertypekey> values are: appletalk, arp,

ibmsna, ipv4, ipv6, ipx, mplsmcast, mplsucast, netbios, novell, pppoe, and
rarp. Each of these translates into its equivalent Ethertype value or values.
The time-range parameter allows imposing time limitation on the MAC ACL rule as
defined by the parameter <time-range-name>. If a time range with the specified name
does not exist and the MAC ACL containing this ACL rule is applied to an interface or bound
to a VLAN, then the ACL rule is applied immediately. If a time range with a specified name
exists and the MAC ACL containing this ACL rule is applied to an interface or bound to a
VLAN, then the ACL rule is applied when the time range with a specified name becomes
active. The ACL rule is removed when the time range with a specified name becomes
inactive.

The assign-queue parameter allows specification of a particular hardware queue for handling
traffic that matches this rule. The allowed <queue-id> value is 0-(n-1), where n is the
number of user configurable queues available for the hardware platform. The
assign-queue parameter is valid only for a permit rule.

mac access-group
This command either attaches a specific MAC access control list (ACL) identified by <name>

must be the name of an existing MAC ACL.
An optional sequence number might be specified to indicate the order of this mac access list
relative to other mac access lists already assigned to this interface and direction. A lower
number indicates higher precedence order. If a sequence number is already in use for this
interface and direction, the specified mac access list replaces the currently attached mac
access list using that sequence number. If the sequence number is not specified for this
command, a sequence number that is one greater than the highest sequence number
currently in use for this interface and direction is used.

IP Access Control List (ACL) Commands
This section describes the commands you use to configure IP ACL settings. IP ACLs ensure
that only authorized users have access to specific resources and block any unwarranted
attempts to reach network resources.
The following rules apply to IP ACLs:
•
Managed switch software does not support IP ACL configuration for IP packet fragments.
•
The maximum number of ACLs you can create is hardware-dependent. The limit applies
to all ACLs, regardless of type.
•
The maximum number of rules per IP ACL is hardware-dependent.
Quality of Service Commands

M4100 Series ProSAFE Managed Switches
•
Wildcard masking for ACLs operates differently from a subnet mask. A wildcard mask is
in essence the inverse of a subnet mask. With a subnet mask, the mask has ones (1's) in
the bit positions that are used for the network address, and has zeros (0's) for the bit
positions that are not used. In contrast, a wildcard mask has (0’s) in a bit position that

Parameter
Description
eq {<portkey> | <0-65535>}
Note: This option is available only if the protocol is tcp or udp.
When eq is specified, an IP ACL rule matches only if the Layer 4
port number is equal to the specified port number or port key.
You can enter the port number, which ranges from 0-65535, or the
port key, which can be one of the following keywords:
For tcp protocol: bgp, domain, echo, ftp, ftp-data, http, smtp,
telnet, www, pop2, or pop3.
For udp protocol: domain, echo, ntp, rip, snmp, tftp, time, or
who.
Each of these keywords translates into its equivalent port number.
Note: Port number matches-only apply to unfragmented or first
fragments.
Note: You can specify a port key or port number for the source and
a port key or port number for the destination.
<dstip> <dstmask>
Specifies a destination IP address and netmask for match condition
of the IP ACL rule.
[precedence <precedence> |
tos <tos> [<tosmask>] | dscp
<dscp>]
Specifies the ToS for an IP ACL rule depending on a match of
precedence or DSCP values using the parameters precedence
<precedence>, tos <tos>, or dscp <dscp>.
<tosmask> is an optional parameter.
[log]
Specifies that this rule is to be logged.
[rate-limit <1-4294967295>
<1-128>]
You can specify a simple rate limiter for packets matching an ACL
permit rule. You must specify the allowed rate of traffic in kbps
(from 1-429496729) and burst size in kbytes (from 1-128). The
conforming traffic is allowed to transmit and nonconforming traffic is
dropped. This action is ignored for any deny rule, because, by
definition, matching packets are dropped.
[assign-queue <queue-id>]
Specifies the assign-queue, which is the queue identifier to which
packets matching this rule are assigned.
[{mirror | redirect}
<slot/port>]
Specifies the mirror or redirect interface, which is the <slot/port>
to which packets matching this rule are copied or forwarded,
respectively.

M4100 Series ProSAFE Managed Switches
Note: An implicit deny all IP rule always terminates the access list.
Note: The mirror parameter allows traffic matching this rule to be copied
to the specified <slot/port>, while the redirect parameter allows
traffic matching this rule to be forwarded to the specified
<slot/port>. The assign-queue and redirect parameters are
valid only for a permit rule.
A rule might either deny or permit traffic according to the specified classification fields. At a
minimum, either every keyword or the protocol, source address, and destination address
values must be specified. The source and destination IP address fields might be specified
using the keyword any to indicate a match on any value in that field. The remaining
command parameters are all optional, but the most frequently used parameters appear in the
same relative order as shown in the command format.
The assign-queue parameter allows specification of a particular hardware queue for
handling traffic that matches this rule. The allowed <queue-id> value is 0-(n-1), where n is
the number of user configurable queues available for the hardware platform. The
assign-queue parameter is valid only for a permit rule.
The time-range parameter allows imposing time limitation on the IP ACL rule as defined by
the parameter <time-range-name>. If a time range with the specified name does not exist
and the IP ACL containing this ACL rule is applied to an interface or bound to a VLAN, then
the ACL rule is applied immediately. If a time range with specified name exists and the IP
ACL containing this ACL rule is applied to an interface or bound to a VLAN, then the ACL rule
is applied when the time range with specified name becomes active. The ACL rule is
removed when the time range with specified name becomes inactive.
You can specify a simple rate limiter for packets matching an ACL permit rule. You must
specify the burst size in kbytes and allowed rate of traffic in kbps. The conforming traffic is
allowed to transmit, and non-conforming traffic is dropped. This action is ignored for any
deny rule, since by definition matching packets are dropped.

AutoVoIP Commands
AutoVoIP detects the VoIP streams and put the VoIP streams in the specific VLAN (auto-voip
VLAN) and provides higher Class of Service to the VoIP streams automatically (both data
and signaling). It detects the VoIP streams in two modes.
•
Protocol-based Auto VoIP. In a VoIP system, various signaling protocols are used to
establish the connection between two VoIP devices. The supported signaling protocols
are SIP, H.323, and SCCP.
•
OUI-based Auto VoIP. The OUI-based Auto VoIP feature prioritizes VoIP packets based
on the OUI bytes in the source MAC address. A default list of OUIs is maintained. User is
also allowed to configure OUIs that need prioritization apart from the default OUI list. Up
to 128 OUIs are allowed on the device or system, including the default OUIs.
Note: If voice VLAN and Auto-VoIP are enabled at the same time, one of
them is operational. If the connected phone is LLDP-MED capable,
voice VLAN has precedence over the Auto VoIP and Auto VoIP is
operational if the phone does not support LLDP-MED.
auto-voip
This command is used to configure auto VoIP mode. The supported modes are
protocol-based and OUI-based. Protocol-based auto VoIP prioritizes the voice data based on

About PoE
Power over Ethernet (PoE) describes a technology to pass electrical power safely along with
data on existing Ethernet cabling. The PSE or power supply equipment is the device or
switch that delivers electrical power, and the PD or powered device is the end device that
powers up through the power delivered along the Ethernet cable.
This technology is governed by two standards:
•
IEEE 802.3af-2003. This is the original standard, also known as the low-power standard,
which mandates delivery of up to 15.4 watts by the PSE. Because of power dissipation,
only 12.95 watts are assured to be available at the powered device (PD). The PD needs
to be designed so that it can accept power over Ethernet cabling. Category 3 cables can
be used to deliver power to the PD. However, with the advent of 802.11n, the newer
wireless APs required more power. To account for this, a newer standard was developed
in 2009, known as 802.3at.
•
IEEE 802.3at-2009. This is the newer standard, also known as PoE+. This is also known
as the high-power standard, which mandates delivery of up to 34.2 watts by the PSE.
Because of power dissipation, PoE+ provides only a maximum of 25.5 watts at the
powered device. Some PSEs can provide up to 51 watts. Before this standard became
available in 2009, the industry started using different implementations to allow for more
power. All these needed to be brought under the purview of the newer 802.3at standard.

poe high-power
Use this command to switch a port from 802.3af mode to high-power mode. This mode is
used to power up devices that require more power than the current IEEE 802.3af power
(more than 12.95 watts at the PD). There are three options:
•
legacy. Use this mode if the device can power up (more than 12.95 watts) with higher
current and it cannot identify itself as a Class 4 device.
•
pre-dot3at. Use this mode if the device cannot identify itself as a Class 4 device and it
does not have LLDP support.
•
dot3at. Use this mode if the device is a Class 4 device capable of figuring out power
requirements through 2-event classification or LLDP.

poe power limit
Use this command to configure the type of power limit for a port. If the power limit type is
user-defined, the command also allows you to configure a maximum power limit.
There are three options:
•
class-based. Allows the port to draw up to the maximum power based on the
classification of the device connected.
•
none. Allows the port to draw up to Class 0 maximum power if it is in low-power mode
and up to Class 4 maximum power if it is in high-power mode.
•
user-defined. Allows you to define the maximum power to the port. This can be a
value from 3 through 32 watts.
Default
User-defined, with a maximum of 30 watts
Format

poe power management
Use this command to configure the power management mode based on each individual PoE
unit or on all PoE units.
Both the power management modes mentioned here will power up a device based on first
come, first served. When the available power is less than the power limit defined on a port, no
more power will be delivered.
Power over Ethernet Commands
320
M4100 Series ProSAFE Managed Switches
Static and dynamic modes differ in how the available power is calculated, as follows:
•
Static Power Management
Available power = power limit of the source - total allocated power where total allocated
power is calculated as the power limit configured on the port.
•
Dynamic Power Management
Available power = power limit of the source - total allocated power, where total allocated
power is calculated as the amount of power consumed by the port.
For example, assume that the power limit of the source is 300 watts. One port is powered up
and is drawing 3 watts of power. The power limit defined on the port is user-defined as
15 watts. In this case, the available power for static and dynamic would be as follows:
•
Static Power Management
Available power = 300 watts - 15 watts = 285 watts
•
Dynamic Power Management
Available power = 300 watts - 3 watts = 297 watts
Default
dynamic
Format

poe priority
Use this command to configure the priority on a specific port. This is used for power
management purposes. The switch might not be able to supply power to all connected
devices, so the port priority is used to determine which ports will supply power if adequate
power capacity is not available for all enabled ports. For ports that have the same priority
level, the lower numbered port will have higher priority. There are three options:
•
crit. Critical priority
•
high. High priority
•
low. Low priority

Use this command to reset the PoE state of every port (in global mode) or a specific port (in
interface mode). When the PoE port status is shown to be in an error state, this command
can be used to reset the PoE port. The command can also reset the power-delivering ports.
Note that this command takes effect only once after it is executed and cannot be saved
across power cycles.

poe timer schedule name
Use this command to allow you to attach a timer schedule to a PoE port.
You can define a time schedule using the existing time range commands. This schedule has
start and stop times. When this timer schedule is applied to a PoE-enabled port, the
capability of the port to deliver power is affected. At the scheduled start time, the PoE port is
disabled such that it cannot deliver any power. At the scheduled stop time, the PoE port is
reenabled so that it can deliver power.
Note: For information about creating a timer schedule, see Time Range
Commands for Time-Based ACLs on page 309.

poe usagethreshold
Use this command to set a threshold (as a percentage) for the total amount of power that can
be delivered by the switch. For example, if the switch can deliver up to a maximum of 300
watts, a usage threshold of 90 percent ensures that only 270 watts are used for delivering
power to devices. This ensures that more power is not drawn than the switch can provide.
When the usage threshold is set, all the PDs are brought down and then brought back up. If
the consumed power is less than the threshold power (in the preceding case, 270 watts),
then the devices continue to power up. If the consumed power is 269 watts or less, the next
device is powered up. The moment consumed power exceeds the threshold power
(270 watts), no other devices can power up.
This command allows you to set the usage threshold based on each individual PoE unit or all
PoE units.

Auto Install Commands
This section describes the Auto Install Commands. Auto Install is a software feature which
provides for the configuration of a switch automatically when the device is initialized and no
configuration file is found on the switch. The Auto Install process requires DHCP to be
enabled by default in order for it to be completed. The downloaded config file is not
automatically saved to the startup-config. An administrator must explicitly issue a save
request in order to save the configuration. The Auto Install process depends upon the
configuration of other devices in the network, including a DHCP or BOOTP server, a TFTP
server and, if necessary, a DNS server.
There are three steps to Auto Install:
1. Configuration or assignment of an IP address for the device.
2. Assignment of a TFTP server.
3. Obtain a configuration file for the device from the TFTP server.

Term
Definition
Mac Address
A unicast MAC address for which the switch has forwarding and or filtering information.
The format is 6 or 8 two-digit hexadecimal numbers that are separated by colons, for
example 01:23:45:67:89:AB. In an IVL system the MAC address will be displayed as
8 bytes.
Interface
The port through which this address was learned.
Interface Index
This object indicates the ifIndex of the interface table entry associated with this port.
Status
The status of this entry. The meanings of the values are:
• Static. The value of the corresponding instance was added by the system or a user
when a static MAC filter was defined. It cannot be relearned.
• Learned. The value of the corresponding instance was learned by observing the
source MAC addresses of incoming traffic, and is currently in use.
• Management. The value of the corresponding instance (system MAC address) is
also the value of an existing instance of dot1dStaticAddress. It is identified with
interface 0/1. and is currently used when enabling VLANs for routing.
• Self. The value of the corresponding instance is the address of one of the switch’s
physical interfaces (the system’s own MAC address).
• GMRP Learned. The value of the corresponding was learned via GMRP and applies
to Multicast.
• Other. The value of the corresponding instance does not fall into one of the other
categories.
If you enter the interface <slot/port> parameter, in addition to the MAC Address and
Status fields, the VLAN ID field displays.

process cpu threshold
Use this command to configure the CPU utilization thresholds. The Rising and Falling
thresholds are specified as a percentage of CPU resources. The utilization monitoring time
period can be configured from 5 seconds to 86,400 seconds in multiples of 5 seconds. The
CPU utilization threshold configuration is saved across a switch reboot. Configuring the
falling utilization threshold is optional. If the falling CPU utilization parameters are not
configured, they take the same value as the rising CPU utilization parameters.

Mode
Global Config
Parameter
Description
rising threshold
The percentage of CPU resources that, when exceeded for the configured rising
interval, triggers a notification. The range is 1–100. The default is 0 (disabled).
rising interval
The duration of the CPU rising threshold violation, in seconds, that must be met to
trigger a notification. The range is 5–86,400. The default is 0 (disabled).
falling threshold
The percentage of CPU resources that, when usage falls below this level for the
configured interval, triggers a notification. The range is 1–100. The default is 0
(disabled). A notification is triggered when the total CPU utilization falls below this
level for a configured period of time. The falling utilization threshold notification is
made only if a rising threshold notification was previously done. The falling utilization
threshold must always be equal or less than the rising threshold value. The CLI does
not allow setting the falling threshold to be greater than the rising threshold.
falling interval
The duration of the CPU falling threshold, in seconds, that must be met to trigger a
notification. The range is 5–86,400. The default is 0 (disabled).

show running-config
Use this command to display or capture the current setting of different protocol packages
supported on the switch. This command displays or captures commands with settings and
configurations that differ from the default value. To display or capture the commands with
settings and configurations that are equal to the default value, include the [all] option.
Note: The output of the show running-config command does not display
the user password, even if you set one different from the default.
The output is displayed in the script format, which can be used to configure another switch
with same configuration. If the optional <scriptname> is provided with a file name
extension of .scr, the output is redirected to a script file.
Note: If you issue the show running-config command from a serial
connection, access to the switch through remote connections (such as
Telnet) is suspended while the output is being generated and displayed.
Note: If you use a text-based configuration file, the show running-config
command displays only configured physical interfaces, that is, if any
interface only contains the default configuration, that interface will be
skipped from the show running-config command output. This is true
for any configuration mode that contains nothing but default
configuration. That is, the command to enter a particular config mode,
followed immediately by its exit command, are both omitted from the
output of the show running-config command (and hence from the
startup-config file when the system configuration is saved.)
This command captures the current settings of the trapflag status:
•
If all the flags are enabled, then the comma\nd displays trapflags all.
•
If all the flags in a particular group are enabled, then the command displays trapflags
group name all.

Use the ias-users keyword to download the IAS user database file. When the IAS user’s
file is downloaded, the switch IAS user's database is replaced with the users and their
attributes in the downloaded file.
In the copy <url> ias-users command, for <url>, use one of the following values for the
IAS user's file:
{{tftp://<ipaddr> | <ipv6address> | <hostname>/<filepath>/<filename>} |
{sftp | scp://<username>@<ipaddress>/<filepath>/<filename>}}
Note: The maximum length for the file path is 160 characters, and the
maximum length for the file name is 31 characters.
For TFTP, SFTP, and SCP, the <ipaddr> or <hostname> parameter is the IP address or
host name of the server, <filepath> is the path to the file, and <filename> is the name
of the file that you want to upload or download. For SFTP and SCP, the <username>
parameter is the user name for logging into the remote server via SSH.
Note: <ip6address> is also a valid parameter for routing packages that
support IPv6.
For switches that support a USB device, the copy command can be used to transfer files from
and to the USB device. The syntax for the USB file is: usb://<filename>. The USB device
can be either a source or destination in the copy command. It cannot be used as both source
and destination in a copy command.

Packet Capture Commands
Packet capture commands assist in troubleshooting protocol-related problems with the
management CPU. The packets to and from the management CPU can be captured in an
internally allocated buffer area for export to a PC host for protocol analysis. Public domain
packet analysis tools like Ethereal can be used to decode and review the packets in detail.
Capturing can be performed in a variety of modes, either transmit-side only, receive-side only,
or both. The number of packets captured will depend on the size of the captured packets.
capture {start | stop}
Use the capture start command to manually start capturing CPU packets for packet
trace. Capturing packets is stopped automatically when 128 packets are captured and have
not yet been displayed during a capture session. It is guaranteed that packets not displayed
and not saved will not be lost when capturing is in progress. Use the capture stop
command to manually stop capturing CPU packets for packet trace before the moment when
128 packets are captured and capturing packets is stopped automatically.The packet capture
operates in three modes:
•
Capture file
•
Remote capture
•
Capture line
The command is not persistent across a reboot cycle.
Format

Parameter
Description
file
In capture file mode, the captured packets are stored in a file on NVRAM. The
maximum file size defaults to 524,288 bytes. The switch can transfer the file to a TFTP
server via TFTP, SFTP, SCP via CLI, web and SNMP. The file is formatted in pcap
format, is named cpuPktCapture.pcap, and can be examined using network
analyzer tools such as Wireshark® by Ethereal®. Starting a file capture automatically
terminates any remote capture sessions and line capturing. After the packet capture is
activated, the capture proceeds until the capture file reaches its maximum size, or
until the capture is stopped manually using the CLI command capture stop.
Utility Commands
400
M4100 Series ProSAFE Managed Switches
Parameter
Description
remote
In remote capture mode, the captured packets are redirected in real time to an
external computer running the Wireshark tool for Microsoft® Windows®. A packet
capture server runs on the switch side and sends the captured packets via a TCP
connection to the Wireshark tool. The remote capture can be enabled or disabled
using the CLI. There should be a Windows computer with the Wireshark tool to display
the captured file. When using the remote capture mode, the switch does not store any
captured data locally on its file system. You can configure the IP port number for
connecting Wireshark to the switch. The default port number is 2002. If a firewall is
installed between the Wireshark PC and the switch, these ports must be allowed to
pass through the firewall. You must configure the firewall to allow the Wireshark
computer to initiate TCP connections to the switch. If the socket connection to
Wireshark has been established, the captured CPU packets are written to the data
socket. Wireshark receives the packets and processes it to display. This continues
until the session is terminated by either end. Starting a remote capture session
automatically terminates the file capture and line capturing.
line
In capture line mode, the captured packets are saved in real-time mode into the RAM
and can be displayed on the CLI. Starting a line capture automatically terminates any
remote capture session and capturing into a file.
no capture

128 packets can be saved into RAM per capturing session. A maximum 128 bytes per packet
can be saved into the RAM. If a packet holds more than 128 bytes, only the first 128 bytes
are saved; data more than 128 bytes is skipped and cannot be displayed in the CLI.
Capturing packets is stopped automatically when 128 packets are captured and have not yet
been displayed during a capture session. Captured packets are not retained after a reload
cycle.

Cable Test Command
The cable test feature enables you to determine the cable connection status on a selected
port.
Note: The cable test feature is supported only for copper cable. It is not
supported for optical fiber cable. If the port has an active link while the
cable test is run, the link can go down for the duration of the test.
cablestatus
This command returns the status of the specified port.
Format
cablestatus <slot/port>
Mode
Privileged EXEC
Field
Description
Cable Status
One of the following statuses is returned:
• Normal. The cable is working correctly.
• Open. The cable is disconnected or there is a faulty connector.
• Short. There is an electrical short in the cable.
• Cable Test Failed. The cable status could not be determined. The cable may in fact
be working.
Cable Length
If this feature is supported by the PHY for the current link speed, the cable length is
displayed as a range between the shortest estimated length and the longest estimated
length. Note that if the link is down and a cable is attached to a 10/100 Ethernet adapter,
then the cable status may display as Open or Short because some Ethernet adapters
leave unused wire pairs unterminated or grounded. Unknown is displayed if the cable
length could not be determined.
sFlow Commands
sFlow is the standard for monitoring high-speed switched and routed networks. sFlow
technology is built into network equipment and gives complete visibility into network activity,
enabling effective management and control of network resources.

sflow receiver <rcvr_idx> {owner <owner-string> {timeout
<rcvr_timeout> | notimeout} | maxdatagram <size> | ip <ip> | port
<port>}
Mode
Global Config
Field
Description
Receiver Index
The sFlow Receiver for this sFlow sampler to which flow samples are to be sent. A value
of zero (0) means that no receiver is configured, no packets will be sampled. Only active
receivers can be set. If a receiver expires, then all samplers associated with the receiver
will also expire. Possible values are 1-8. The default is 0.
Receiver Owner
The identity string for the receiver, the entity making use of this sFlowRcvrTable entry.
The range is 127 characters. The default is a null string. The empty string indicates that
the entry is currently unclaimed and the receiver configuration is reset to the default
values. An entity wishing to claim an sFlowRcvrTable entry must ensure that the entry is
unclaimed before trying to claim it. The entry is claimed by setting the owner string to a
non-null value. The entry must be claimed before assigning a receiver to a sampler or
poller.
Receiver
Timeout
The time, in seconds, remaining before the sampler or poller is released and stops
sending samples to receiver. A management entity wanting to maintain control of the
sampler is responsible for setting a new value before the old one expires. The allowed
range is 0-4294967295 seconds. The default is zero (0).
Receiver Max
Datagram Size
The maximum number of data bytes that can be sent in a single sample datagram. The
management entity should set this value to avoid fragmentation of the sFlow datagrams.
The allowed range is 200 –9,116). The default is 1400.
Receiver IP
The sFlow receiver IP address. If set to 0.0.0.0, no sFlow datagrams will be sent. The
default is 0.0.0.0.
Receiver Port
The destination Layer4 UDP port for sFlow datagrams. The range is 1-65535. The
default is 6343.

sflow sampler
A data source configured to collect flow samples is called a poller. Use this command to
configure a new sFlow sampler instance for this data source if <rcvr-idx> is valid.
Format
sflow sampler {<rcvr-indx> | rate <sampling-rate> | maxheadersize
<size>}
Mode
Interface Config
Field
Description
Receiver Index
The sFlow Receiver for this sFlow sampler to which flow samples are to be sent. A value
of zero (0) means that no receiver is configured, no packets will be sampled. Only active
receivers can be set. If a receiver expires, then all samplers associated with the receiver
will also expire. Possible values are 1-8. The default is 0.
Sampling Rate
The statistical sampling rate for packet sampling from this source. A value of zero (0)
disables sampling. A value of N means that out of N incoming packets, 1 packet will be
sampled. The range is 1024-65536 and 0. The default is 0.
When you issue a show command for the sampling rate, the configured sampling rate on
an interface changes. Each time that you configure a sampling rate, a threshold value is
calculated. This threshold value is configured in the hardware register. When you issue a
show command for the sampling rate, the threshold value is queried from the hardware
and the sampling rate is calculated in the following way:
threshold value = 2^24/ (sampling rate)
Because only an integer operation is supported, the sampling rate is not the same as the
configured value.
The following is an example:
configured sampling rate is 60000
threshold value = 2^24/ (60000) = 279 (from integer division)
recalculated sampling rate = 2^24/ (279) = 60133
Maxheadersize
The maximum number of bytes that should be copied from the sampler packet. The
range is 20-256. The default is 128. When set to zero (0), all the sampler parameters are
set to their corresponding default value.
no sflow sampler
Use this command to reset the sFlow sampler instance to the default settings.

RMON Stats and History Commands
The various MIBs within RFC 2819, 3273, and 3434 are arranged into groups. The managed
switch supports some of the groups in these RFCs but not all. The managed switch complies
with MODULE-COMPLIANCE and OBJECT-GROUP definitions within these RFCs for
supporting individual groups.
The managed switch supports the following groups:
•
RFC 2819
-
Group 1 - Statistics
Contains cumulative traffic and error statistics.
-
Group 2 - History
Generates reports from periodic traffic sampling that are useful for analyzing trends.
This group includes History Control Group and Ethernet History Group.
-
Group 3 - Alarm
Enables the definition and setting of thresholds for various counters. Thresholds can
be passed in either a rising or falling direction on existing MIB objects, primarily those
in the Statistics group. An alarm is triggered when a threshold is crossed and the
alarm is passed to the Event group. The Alarm requires the Event Group.
-
Group 9 - Event
Controls the actions that are taken when an event occurs. RMON events occur when:
•
•
A threshold (alarm) is exceeded
•
There is a match on certain filters.
RFC 3273
-
Group 1 - Media Independent Group
Contains media-independent statistics that provide information for full and/or
half-duplex links as well as high capacity links.
-
Group 2 - Ether Stats High Capacity Group
Contains the High Capacity RMON extensions to RMON-1 etherStatsTable (RFC
2819 Group 1).

Switch Management CPU Commands
To manage the switch via the web GUI or telnet, an IP address needs to be assigned to the
switch management CPU. Whereas there are CLI commands that can be used to do this,
ezconfig simplifies the task. The tool allows you to configure the following parameters:
1. The administrator’s user password and administrator-enable password
2. Management CPU IP address and network mask
3. System name and location information
The tool is interactive and uses questions to guide you through the steps required to perform
its task. At the end of the session, it will ask you if you want to save the changed information.
To see exactly what has been changed by ezconfig at the end of the session, use the show
running-config command.
To perform any switch configuration other than the items listed above, use other CLI
commands or the web GUI.
ezconfig
This command sets the IP address, subnet mask, and gateway of the device. The IP address

show network
Use this command to display configuration settings associated with the switch’s network
interface. The network interface is the logical interface used for in-band connectivity with the
switch via any of the switch's front panel ports. The configuration parameters associated with
the switch's network interface do not affect the configuration of the front panel ports through
which traffic is switched or routed. The network interface is always considered to be up,
whether any member ports are up; therefore, the show network command will always show
“Interface Status” as “up”.

Interface Status
The network interface status; it is always considered to be “up”.
IP Address
The IP address of the interface. The factory default value is 0.0.0.0.
Subnet Mask
The IP subnet mask for this interface. The factory default value is 0.0.0.0.
Default Gateway The default gateway for this IP interface. The factory default value is 0.0.0.0.

The IPv6 default router address.
Burned In MAC
Address
The burned in MAC address used for in-band connectivity.
Locally
Administered
MAC Address
If desired, a locally administered MAC address can be configured for in-band
connectivity. To take effect, 'MAC Address Type' must be set to 'Locally Administered'.
Enter the address as twelve hexadecimal digits (6 bytes) with a colon between each
byte. Bit 1 of byte 0 must be set to a 1 and bit 0 to a 0, that is, byte 0 should have the
following mask “xxxx xx10”. The MAC address used by this bridge when it must be
referred to in a unique fashion. It is recommended that this be the numerically smallest
MAC address of all ports that belong to this bridge. However it is only required to be
unique. When concatenated with dot1dStpPriority a unique BridgeIdentifier is formed
which is used in the Spanning Tree Protocol.
MAC Address
Type
The MAC address which should be used for in-band connectivity. The choices are the
burned in or the Locally Administered address. The factory default is to use the burned in
MAC address.

User Account Commands
This section describes the commands you use to add, manage, and delete system users.
The software has two default users: admin and guest. The admin user can view and
configure system settings, and the guest user can view settings.
Note: You cannot delete the admin user. There is only one user allowed with
read/write privileges. You can configure up to five read-only users on
the system.
username (Global Config)
Use this command to add a new user to the local user database. The default privilege level
is 1. Using the encrypted keyword allows the administrator to transfer local user passwords
between devices without having to know the passwords. When the password parameter is
used along with encrypted parameter, the password must be exactly 128 hexadecimal
characters in length. If the password strength feature is enabled, this command checks for
password strength and returns an appropriate error if it fails to meet the password strength
criteria. The optional override-complexity-check parameter disables the validation of
the password strength.
Format

domain-name (Global Config)
The managed switch supports authentication based on domain name, in addition to the user
name and password. This command allows the switch to be configured in a domain. Users
can enable or disable domain functionality:
•
Domain enabled. In this case, when the user enters only the user name, the managed
switch sends the domain name that is configured on the switch and the user name that
the user enters in the format "domainname\username” to the RADIUS server.
If the user enters the domain name and user name, the managed switch sends the
domain name and user name that the user enters in the format "domainname\username”
to the RADIUS server.
•
Domain disabled. In this case, the domain name is not included when the user name is
sent to the RADIUS server.

Client IP Mask
A mask to be ANDed with the requesting entity's IP address before comparison with IP
address. If the result matches with IP address then the address is an authenticated IP
address. For example, if the IP address = 9.47.128.0 and the corresponding Subnet
Mask = 255.255.255.0 a range of incoming IP addresses would match, i.e. the incoming
IP address could equal 9.47.128.0 - 9.47.128.255. The default value is 0.0.0.0.

radius server host
This command configures the IP address or DNS name to use for communicating with the
RADIUS server of a selected server type. While configuring the IP address or DNS name for
the authenticating or accounting servers, you can also configure the port number and server
name. If the authenticating and accounting servers are configured without a name, the
command uses the Default_RADIUS_Auth_Server and Default_RADIUS_Acct_Server as the
Management Commands

M4100 Series ProSAFE Managed Switches
default names, respectively. The same name can be configured for more than one
authenticating servers and the name should be unique for accounting servers. The RADIUS
client allows the configuration of a maximum 32 authenticating and accounting servers.
If you use the auth parameter, the command configures the IP address or host name to use
to connect to a RADIUS authentication server. You can configure up to three servers per
RADIUS client. If the maximum number of configured servers is reached, the command fails
until you remove one of the servers by issuing the no form of the command. If you use the
optional port parameter, the command configures the UDP port number to use when
connecting to the configured RADIUS server. For the port keyword, the <number>
argument must be a value in the range 0–65535, with 1813 being the default.
Note: To reconfigure a RADIUS authentication server to use the default
UDP port, set the <number> argument to 1812.
If you use the acct token, the command configures the IP address or host name to use for
the RADIUS accounting server. You can only configure one accounting server. If an
accounting server is currently configured, use the no form of the command to remove it from
the configuration. The IP address or host name you specify must match that of a previously
configured accounting server. If you use the optional port parameter, the command
configures the UDP port to use when connecting to the RADIUS accounting server. If a port
is already configured for the accounting server, the new port replaces the previously
configured port. For the port keyword, the <number> argument must be a value in the
range 0–65535, with 1813 being the default.
Note: To reconfigure a RADIUS accounting server to use the default UDP
port, set the <number> argument to 1813.

TACACS+ Commands
TACACS+ provides access control for networked devices via one or more centralized
servers. Similar to RADIUS, this protocol simplifies authentication by making use of a single
database that can be shared by many clients on a large network. TACACS+ is based on the
TACACS protocol (described in RFC1492) but additionally provides for separate
authentication, authorization, and accounting services. The original protocol was UDP based
with messages passed in clear text over the network. TACACS+ uses TCP to ensure reliable
delivery and a shared key configured on the client and daemon server to encrypt all
messages.

Configuration Scripting Commands
Configuration Scripting allows you to generate text-formatted script files representing the
current configuration of a system. You can upload these configuration script files to a
computer or UNIX system and edit them. Then, you can download the edited files to the
system and apply the new configuration. You can apply configuration scripts to one or more
switches with no or minor modifications.
Use the show running-config command (see show running-config on page 349) to
capture the running configuration into a script. Use the copy command (see copy on
page 371) to transfer the configuration script to or from the switch.
You should use scripts on systems with default configuration; however, you are not prevented
from applying scripts on systems with non-default configurations.
Scripts must conform to the following rules:
•
Script files are not distributed across the stack, and only live in the unit that is the master
unit at the time of the file download.
•
The file extension must be “.scr”.
•
A maximum of ten scripts are allowed on the switch.
•
The combined size of all script files on the switch shall not exceed 2048 KB.
•
The maximum number of configuration file command lines is 2000.
You can type single-line annotations at the command prompt to use when you write test or
configuration scripts to improve script readability. The exclamation point (!) character flags
the beginning of a comment. The comment flag character can begin a word anywhere on the
command line, and all input following this character is ignored. Any command line that begins
with the “!” character is recognized as a comment line and ignored by the parser.
Management Commands

Energy-Detect Mode
When Energy-Detect mode is enabled, if communication on a port stops, the port circuitry
automatically shuts down for a short period. The port wakes up periodically to check for link
activity. If activity is detected, the port circuitry remains active. This allows performing
autonegotiation and saving power when there is no active link.
Note: Combination ports support both copper and fiber media. Energy
Detect mode only applies to copper media. If Energy Detect mode is
configured on a combination port, it will only function when a copper
media is active.
Green Ethernet Commands
523
M4100 Series ProSAFE Managed Switches
Energy Efficient Ethernet (EEE)
Energy Efficient Ethernet (EEE) combines MAC with ports that support operation in a
Low-Power Mode. This feature is defined by the IEEE 802.3az Energy Efficient Ethernet
Task Force. Lower Power Mode enables both send and receive sides of a link to disable
some port functionality to save power when the port is lightly loaded. Transition to Low-Power
Mode does not change the link status. Frames in transit are not dropped or corrupted during
transition to and from Low-Power Mode. This transition time is transparent to upper layer
protocols and applications.
EEE operation is subject to the following conditions:
•
Autonegotiation must be enabled to use any of the EEE modes. EEE mode is disabled
automatically when autonegotiation is disabled.
•
Enabling or Disabling EEE mode causes the port link to flap once as EEE capability
needs to be advertised. This restarts autonegotiation.
•
EEE must be disabled while running hardware or software cable diagnostics.
•
Combo (Combination) ports: Combo ports support both copper and fiber media. EEE
mode only applies to copper media. If Energy Detect mode is configured on a
combination port, it will only function when a copper media is active. EEE LPI statistics
are only collected if a copper media is used on the port. If the media on a port changes
from copper to fiber while EEE is enabled, LPI statistics collection stops until the media
changes back to copper. The outputs of the show green-mode <slot/port> and
show green-mode eee-lpi-history interface <slot/port> commands
display updated LPI statistics only if the medium is copper.
