Chapter 24: Multicast Listener Discovery (MLD) Snooping Commands
436 Section IV: Security and Traffic Control
Description
Use this command to specify the timeout and changes the settings of the
multicast group for MLD Snooping.
By default, the switch forwards multicast traffic to all ports belong to the
same VLAN if any of the ports is a member of the multicast group. When
MLD Snooping is enabled, the switch snoops MLD messages and
forwards multcast traffic only to multicast member ports.
Here are the guidelines for router ports:
A router port is canceled when the port does not receive a query
packet for the certain period of time; however, a router port is not
canceled if the multicast group was added by the ADD MLD
SNOOPING MCGROUP command.
When the routerport paramter is specified to none or auto, all
multicast groups specified by the ADD MLDSNOOPING
MCGROUP command are deleted.
Confirmation Command
