Command Usage
â—† The IGMP filtering profile must first be created with the ip igmp profile
command before being able to assign it to an interface.
â—† Only one profile can be assigned to an interface.
â—† A profile can also be assigned to a trunk interface. When ports are configured as
trunk members, the trunk uses the filtering profile assigned to the first port
member in the trunk.

Console(config-if)#ip igmp filter 19
