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.)
