IGMP Snooping
– 667 –
ip igmp snooping This command enables IGMP snooping globally on the switch or on a selected
VLAN interface. Use the no form to disable it.
Syntax
[no] ip igmp snooping [vlan vlan-id]
vlan-id - VLAN ID (Range: 1-4094)
Default Setting
Disabled
Command Mode
Global Configuration
Command Usage
◆ When IGMP snooping is enabled globally, the per VLAN interface settings for
IGMP snooping take precedence.
◆ When IGMP snooping is disabled globally, snooping can still be configured per
VLAN interface, but the interface settings will not take effect until snooping is
re-enabled globally.
Example
The following example enables IGMP snooping globally.
Console(config)#ip igmp snooping
Console(config)#
clear ip igmp snooping
statistics
Clears IGMP snooping statistics PE
show ip igmp snooping Shows the IGMP snooping, proxy, and query configuration PE
show ip igmp snooping
group
Shows known multicast group, source, and host port
mapping
PE
show ip igmp snooping
mrouter
Shows multicast router ports PE
show ip igmp snooping
statistics
Shows IGMP snooping protocol statistics for the specified
interface
