Allied Telesis AT-GS900M Series User Manual

AT-GS900M Series CLI Reference
Section IV: Security and Traffic Control 425
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
IGMP Snooping is enabled, the switch snoops IGMP 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
IGMPSNOOPING MCGROUP command.
 When the routerport paramter is specified to none or auto, all
multicast groups specified by the ADD IGMPSNOOPING
MCGROUP command are deleted.
Confirmation Command
“SHOW IGMPSNOOPING” on page 427
Example
The following command sets the timeout for IGMP Snooping:
Manager > set igmpsnooping timeout=300
