The frequency at which IGMP general query packets are
transmitted by the querying switch in seconds.
So this is the time between general periodic queries being
sent out of the switch when it is acting as the IGMP querier.
Large values lead to IGMP queries being sent less often.
The default is 125 seconds and the range is 2 to 3599 seconds.
Note: The following dependency is needed: Max. Response Time < Querier Transmit Interval < Group Membership Interval.
