Usage Guidelines You can apply IGMP filters only to Layer 2 physical interfaces; you cannot apply IGMP filters to routed
ports, switch virtual interfaces (SVIs), or ports that belong to an EtherChannel group.
An IGMP profile can be applied to one or more switch port interfaces, but one port can have only one
profile applied to it.
Examples This example shows how to apply IGMP profile 22 to an interface.
Switch(config)# interface fastethernet0/1
Switch(config-if)# ip igmp filter 22
You can verify your setting by using the show running-config interface interface-id privileged EXEC
command.
