IP IGMP SNOOPING
ip igmp snooping
Overview
Use this command to enable IGMP Snooping. When this command is used in the
Global Configuration mode, IGMP Snooping is enabled at the device level. When
this command is used in Interface Configuration mode, IGMP Snooping is enabled
for the specified VLANs.
Use the no variant of this command to either globally disable IGMP Snooping, or
disable IGMP Snooping on a specified interface.
NOTE
already been disabled globally. IGMP snooping can be disabled on both an interface
and globally if disabled on the interface first and then disabled globally.
ip igmp snooping
Syntax
no ip igmp snooping
Default
By default, IGMP Snooping is enabled both globally and on all VLANs.
Mode
Global Configuration and Interface Configuration for a VLAN interface.
Usage notes
It is possible to disable IGMP snooping globally or on a per-VLAN basis, using the
command no ipv6 igmp snooping. However, we recommend leaving IGMP
snooping enabled unless an Allied Telesis support representative tells you to
disable it, even if you are not actively using the device for multicast.
For IGMP snooping to operate on particular VLAN interfaces, it must be enabled
both globally by using this command in Global Configuration mode, and on
individual VLAN interfaces by using this command in Interface Configuration
mode (both are enabled by default).
Examples
To enable IGMP Snooping on vlan2, use the commands:
awplus#
awplus(config)#
awplus(config)#
awplus(config-if)#
