5.25 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.
