determined by the (count + 0.5) * LMQI. The result is that the default leave latency can range from 2.0 to 3.0
seconds with an average of 2.5 seconds under a higher load of IGMP leave processing. The leave latency
under load for the minimum LMQI value of 100 milliseconds and a count of 1 is from 100 to 200 milliseconds,
with an average of 150 milliseconds. This is done to limit the impact of higher rates of IGMP leave messages.
Examples
The following example sets the last member query count to 5:
Device(config)# ip igmp snooping last-member-query-count 5
