IGMP Snooping 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.
