Interface view

seconds: Time interval before IGMP query router sends the IGMP group query 
message after it receives the IGMP Leave message from the host. It is in the range 
of 1 to 5 seconds. By default, it is 1 second.

Use the igmp lastmember-queryinterval command to set the time interval at 
which IGMP query router sends the IGMP group query message after it receives 
the IGMP Leave message from the host.

Use the undo igmp lastmember-queryinterval command to restore the default 
value.

This command is valid only when the query router runs IGMP v2. If the host runs 
IGMP v1 , it does not send an IGMP Leave message when it leaves a group, so this 
command is invalid for the IGMP query router.

Related command: igmp robust-count and display igmp interface.

# Set the query interval at the Vlan-interface10 as 3 seconds.

igmp max-response-time seconds

Interface view

seconds: Maximum response time in the IGMP query messages in second in the 
range from 1 to 25. By default, the value is 10 seconds.

Use the igmp max-response-time command to configure the maximum 
response time contained in the IGMP query messages.

Use the undo igmp max-response-time command to restore the default value.

The maximum query response time determines the period for a router to quickly 
detect that there are no more directly connected group members in a LAN.
