Use the set igmp command to enable or disable IGMP snooping on the switch.
set igmp {enable | disable}
Syntax Description
enable
|
Keyword to enable IGMP snooping on the switch.
|
disable
|
Keyword to disable IGMP snooping on the switch.
|
Defaults
IGMP snooping is disabled.
Command Types
Switch command.
Command Modes
Privileged.
Usage Guidelines
IGMP snooping requires supervisor engine software release 4.1 or later, a Supervisor Engine III or Supervisor Engine II G or III G, and a network connection from the switch to a router running IGMP.
Before enabling IGMP snooping, you must disable CGMP and CGMP leave processing (by using the set cgmp and set cgmp leave commands).
Examples
This example shows how to enable IGMP snooping on the switch:
Console> (enable) set igmp enable
IGMP Snooping is enabled.
This example shows what happens if you try to enable IGMP if CGMP is already enabled:
Console> (enable) set igmp enable
Disable CGMP to enable IGMP Snooping feature.

set igmp fastleave {enable | disable}
Syntax Description
enable
|
Keyword to enable IGMP fastleave processing.
|
disable
|
Keyword to disable IGMP fastleave processing.
|
Defaults
By default, IGMP fastleave processing is disabled.
Command Types
Switch command.
Command Modes
Privileged.
Examples
This example shows how to enable IGMP fastleave processing:
Console> (enable) set igmp fastleave enable
IGMP support for fastleave processing enabled.
This example shows how to disable IGMP fastleave processing:
Console> (enable) set igmp fastleave disable
IGMP support for fastleave processing disabled.

set igmp mode
Use the set igmp mode command to set the IGMP snooping mode.
set igmp mode {igmp-only | igmp-cgmp | auto}
Syntax Description
igmp-only
|
Keyword to specify IGMP snooping only.
|
igmp-cgmp
|
Keyword to specify IGMP and CGMP modes.
|
auto
|
Keyword to override the dynamic switching of IGMP snooping modes.
|
Defaults
The default is IGMP mode is auto.
Command Types
Switch.
Command Modes
Privileged.
Usage Guidelines
The switch dynamically chooses either IGMP-only or IGMP-CGMP mode, depending on the traffic present on the network. IGMP-only mode is used in networks with no CGMP devices. IGMP-CGMP mode is used in networks with both IGMP and CGMP devices. Auto mode overrides the dynamic switching of the modes.
Examples
This example shows how to set the IGMP mode to IGMP-only:
Console> (enable) set igmp mode igmp-only
IGMP mode set to igmp-only
This example shows how to set the IGMP mode to auto:
Console> (enable) set igmp mode auto

set interface
Use the set interface command to set the network interface configuration and to enable or disable standard SNMP trap operation.
set interface {sc0 | me1 | sl0} {up | down}
set interface sc0 [vlan] [ip_addr [netmask [broadcast]]]
set interface sc0 [vlan] [ip_addr[/netmask] [broadcast]]
set interface me1 ip_addr [netmask [broadcast]]
set interface me1 ip_addr [/netmask [broadcast]]
set interface sl0 slip_addr dest_addr
set interface sc0 dhcp {renew | release}
Syntax Description
sc0
|
Keyword to specify the in-band management interface.
|
me1
|
Keyword to specify the out-of-band management Ethernet interface.
|
sl0
|
Keyword to specify the SLIP interface.
|
up
|
Keyword to bring the interface into operation.
|
down
|
Keyword to bring the interface out of operation.
|
vlan
|
(Optional) Number of the VLAN to be assigned to the interface.
|
ip_addr
|
(Optional) IP address to assign to the interface.
|
netmask
|
(Optional) Subnet mask or mask bits to assign to the interface.
|
broadcast
|
(Optional) Broadcast address to assign to the interface.
|
slip_addr
|
SLIP source address of the console port.
|
dest_addr
|
SLIP destination address of the host to which the console port will be connected.
|
dhcp
|
Keyword to perform DHCP operations on the sc0 interface.
|
renew
|
Keyword to renew the lease on a DHCP-learned IP address.
|
release
|
Keyword to release a DHCP-learned IP address back to the DHCP IP address pool.
|
Defaults
The default configuration has the IP address, subnet mask, and broadcast address of the in-band management interface (sc0) and out-of-band management Ethernet interface (me1) set to 0.0.0.0, with the sc0 interface in VLAN 1. The default configuration for the SLIP interface (sl0) is that the SLIP source and destination addresses are set to 0.0.0.0.
Command Types
Switch command.
Command Modes
Privileged.
Usage Guidelines
The Catalyst 5000 family switches support two IP management interfaces, the in-band management interface (sc0) and the SLIP interface (sl0). The sc0 interface is attached to the switching fabric of the switch. The slip interface is an out-of-band management port because it is not attached to the switching fabric and no traffic is switched over it.
You can enter the netmask value in dotted decimal format or you can specify the number of bits in the netmask (for example, 204.20.22.7/24).
Examples
This example shows how to use set interface sc0 and set interface sl0 from the console port. It also shows how to bring down interface sc0 using a terminal connected to the console port:
Console> (enable) set interface sc0 192.200.11.44 255.255.255.0
Interface sc0 IP address and netmask set.
Console> (enable) set interface sl0 192.200.10.45 192.200.10.103
Interface sl0 SLIP and destination address set.
Console> (enable) set interface sc0 down
Interface sc0 administratively down.
This example shows how to set the IP address for sc0. If you do not specify a subnet mask, the default mask for that IP address class is used (for example, 255.255.0.0 for a class B address):
Console> (enable) set interface sc0 172.20.52.123
Interface sc0 IP address and netmask set.
This example shows how to set the VLAN, IP address, and subnet mask bits for the sc0 interface:
Console> (enable) set interface sc0 5 172.20.52.123/28
Interface sc0 vlan set, IP address and netmask set.
