Configuring IGMP Snooping Timer
The IGMP snooping process uses the following parameters for setting the timer value.

Last Member Query Interval
9
Last Member Query Count
9
Robustness Variable
9
Query Interval

Other Query Interval

Unsolicited Report Interval
When the switch receives the IGMP leave message (not in fast-leave state), it removes a port from the
IGMP snooping group. At that time, the IGMP snooping leave timeout value is determined by the last
member query interval and the last member query count. This shows how to calculate the IGMP
snooping leave timeout, and default and range of last member query interval and last member query
count.
−
IGMP Snooping Leave Timeout = Last Member Query Interval * Last Member Query Count
−
Last Member Query Interval : default(1000msec), minimum(1000msec),
maximum(25500msec)
−
Last Member Query Count : default(2), minimum(2), maximum(7)
Beginning in Enable mode, follow these steps how to configure the last member query interval value.
