Multicast Filtering Commands

This switch uses IGMP (Internet Group Management Protocol) to query
for any attached hosts that want to receive a specific multicast service. It
identifies the ports containing hosts requesting a service and sends data
out to those ports only. It then propagates the service request up to any
neighboring multicast switch/router to ensure that it will continue to
receive the multicast service.
Note that IGMP query can be enabled globally at Layer 2, or enabled for
specific VLAN interfaces at Layer 3. (Layer 2 query is disabled if Layer 3
query is enabled.)
