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.
