The output of the
show igmp
command provides the following useful information:
•
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.
•
Multicasting Unknown Streams
shows if the control of multicast streams is on
(Enabled) or off (Disabled).
The
show-group
command displays the multicast groups.
