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.
