IGMP Snooping
– 675 –
Command Mode
Global Configuration
Command Usage
This command configures the IGMP report/query version used by IGMP
snooping. Versions 1 - 3 are all supported, and versions 2 and 3 are backward
compatible, so the switch can operate with other devices, regardless of the
snooping version employed.
If the IGMP snooping version is configured on a VLAN, this setting takes
precedence over the global configuration.
Example
The following configures the global setting for IGMP snooping to version 1.
Console(config)#ip igmp snooping version 1
Console(config)#
ip igmp snooping
version-exclusive
This command discards any received IGMP messages (except for multicast protocol
packets) which use a version different to that currently configured by the ip igmp
snooping version command. Use the no form to disable this feature.
Syntax
ip igmp snooping [vlan vlan-id] version-exclusive
no ip igmp snooping [vlan vlan-id] version-exclusive
vlan-id - VLAN ID (Range: 1-4094)
Default Setting
Global: Disabled

Command Mode

Command Usage

compatible (see the ip igmp snooping version command.
