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.
