The output of “show igmp” provide useful information. The following information is provided:
IGMP State shows if IGMP is turned on (Enable) or off (Disable).

traffic.

the switch is the querier.
Querier Interval shows the time period in seconds on which the switch sends general host-
query messages.

between when the querier sends a host-query message and when it receives a response from
a host.
