23 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.

Note:

A single table maintains a maximum of 511 entries learned for both IGMP

and MLD snooping.

Note:

Only ASM (any-source multicast) mode is supported on IGMPv3 and MLDv2.

SSM (source-specific multicast) on IGMPv3 and MLDv2 is not supported

. If a client

sends an SSM report to the switch, the client will not join the multicast group.
