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.
