4.3.14 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 continues to receive the multicast service.
