Chapter 17 Configuring IGMP Snooping and Filtering
Configuring IGMP Filtering
To delete a profile, use the no ip igmp profile profile number global configuration command.
To delete an IP multicast address or range of IP multicast addresses, use the no range ip multicast
address IGMP profile configuration command.

This example shows how to create IGMP profile 4 (allowing access to the single IP multicast address)
and how to verify the configuration. If the action were to deny (the default), it would not appear in the
show ip igmp profile command output.

Applying IGMP Profiles
To control access as defined in an IGMP profile, use the ip igmp filter interface configuration command
to apply the profile to the appropriate interfaces. You can apply a profile to multiple interfaces, but each
interface can only have one profile applied to it.

You can apply IGMP profiles to Layer 2 ports only. You cannot apply IGMP profiles to routed ports (or
