CR00014222 IGMP
snooping,
Switch,
VLAN
- IGMP snooping learns which ports have routers attached to them, so it can
forward relevant IGMP messages out those ports. By default, snooping identifies
router ports by looking for ports that receive specific multicast packets (such as
IGMP queries, PIM messages, OSPF messages, and RIP messages).
In some network configurations, this learning process cannot identify all router
ports. For such networks, this enhancement enables you to statically configure
particular ports as multicast router ports.
To specify the static router ports, use the new command:
add igmpsnooping vlan={vlan-name|1..4094} routerport=port-list
To stop ports from being static router ports, use the new command:
delete igmpsnooping vlan={vlan-name|1..4094} routerport=port-list
To list the static router ports, use the existing command:
show igmpsnooping
and check the new “Static Router Ports” field.
