Configuring IGMP Profiles

To configure an IGMP profile and to enter IGMP profile configuration mode, use the ip igmp profile
global configuration command. From the IGMP profile configuration mode, you can specify the
parameters of the IGMP profile to be used for filtering IGMP join requests from a port. When you are
in IGMP profile configuration mode, you can create the profile using these commands:
