NOTE
If IGMP snooping is disabled in a VLAN, you can still configure IGMP snooping functions, but the
configuration does not take effect. In this case, no information is displayed after you run the display igmp-
snooping command.
If the configurations succeed, you can obtain the following information after running the display
igmp-snooping [ vlan vlan-id ] command :
l IGMP snooping is enabled in the VLAN.
l The IGMP version is set correctly.
l A multicast group policy is correctly set for the VLAN.
l Prompt leave is enabled for interfaces in the VLAN.
l Aging time of the router interface, interval for sending Last Member Query messages,
interval for sending IGMP General Query messages, maximum response time, suppression
duration of IGMP messages, and IGMP robustness variable are correctly set.
l The Router Alert option is set correctly.
The following is an example.
