• 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 a querier or a non-querier. In our example, 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).
