117 – Enabling IGMP and query the status of IGMP


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).

Immediate Leave provides a mechanism for a particular host that wants to leave a multicast
group. It disables the port (where the leave message is received) ability to transmit multicast
traffic.

Querier shows where the switch is acting a querier or a non-querier. In the example above
the switch is the querier.

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

Querier Response Interval specifies maximum amount of time in seconds that can elapse
between when the querier sends a host-query message and when it receives a response from
a host.
