By configuring the IGS switch as a querier, the switch starts sending general queries at regular time intervals. The querier message sent by the switch does not take part in querier election. If the switch receives a query from any other router, the switch stops acting as a querier.
SEFOS# configure terminal SEFOS(config)# vlan 4
SEFOS(config-vlan)# ip igmp snooping querier SEFOS(config-vlan)# end SEFOS#
The switch sends general queries on the member ports of VLAN 4 every 125 seconds.
SEFOS# show ip igmp snooping vlan 4 Snooping VLAN Configuration for the VLAN 4 IGMP Snooping enabled IGMP configured version is V3 Fast leave is disabled Snooping switch is configured as Querier Snooping switch is acting as Querier Query interval is 125 seconds Port Purge Interval is 260 seconds Max Response Code is 100, Time is 10 seconds
