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.
