Command Usage
The switch must be using IGMPv2 for this command to take effect.
This command defines how long any responder (i.e., client or router) still in the
group has to respond to a query message before the router deletes the group.
By varying the Maximum Response Interval, you can tune the burstiness of
IGMP messages passed on the subnet; where larger values make the traffic
less bursty, as host responses are spread out over a larger interval.
The number of seconds represented by the maximum response interval must
be less than the Query Interval (page 4-236).
Example
The following shows how to configure the maximum response time to 20 seconds:
