IGMP snooping and MVR
This switch uses IGMP snooping 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.
Multicast Snooping show commands
This section describes the show commands used to debug IGMP snooping and MVR.
