Controlling Access to IP Multicast Group (CLI)

The device sends IGMP host-query messages to find which multicast groups have members on attached local
networks. The device then forwards to these group members all packets addressed to the multicast group.
You can place a filter on each interface to restrict the multicast groups that hosts on the subnet serviced by
the interface can join.
To limit the number of joins on the interface, configure the port for the filter which associates with the IGMP
profile.
This procedure is optional.
