Controlling Access to IP Multicast Group

The switch sends IGMP host-query messages to find which multicast groups have members on attached local
networks. The switch 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.
This procedure is optional.
