Command: ip igmp query-max-response-time <time_val>
no ip igmp query- max-response-time
Function: Set the maximum time for a interface to response to a IGMP query; the “no ip

Command mode: Interface Mode
Usage Guide: On receiving a query message from the switch, the host will set a counter
for each multicast group it belongs to, the counter value is random from 0 to

the host will send the member report message for the multicast group. Set
the maximum response time sensibly enable fast responds of host to query
messages, the router can also get the existing status of the multicast group
members.
Example: Set the maximum IGMP query response time to 20 seconds.
