Command Default Level
Level: 12.
Usage Guideline
When the router receives a leave message from a receiver to claim leave from a group or a channel, the
router will send the group specific query or group-source specific query message to the receiver interface.
The IGMP last-member query interval will be advertised in the query message and conveyed to the
receiver. This command configures the period that the router will send the next group-specific query or
group-source specific query message if there is no report from receiver for the specific group or specific
channel. The router will retry for the last member query count. If there is no report messages received
after the retry count, the interface will be removed the membership from the specific group or specific
channel.
Example
This example shows how to configure the IGMP last member query interval value to 2 seconds on VLAN
1000.
Switch# configure terminal
Switch(config)# interface vlan1000
Specifies the interval at which IGMP group-specific host query
messages are sent. The range is from 1 to 25.
