Multicast Filtering Commands
This switch uses IGMP (Internet Group Management Protocol) to check 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.
IGMP Snooping
This section describes commands used to configure IGMP snooping on the switch.
