Users Guide
• When enabled, IGMP snooping Querier periodically sends general queries with an IP source address of the VLAN interface. If it receives
a general query on any of its VLAN member, it checks the IP source address of the incoming frame.
If the IP SA in the incoming IGMP general query frame is lower than the IP address of the VLAN interface, the switch disables its IGMP
snooping Querier functionality.
If the IP SA of the incoming IGMP general query is higher than the VLAN IP address, the switch continues to work as an IGMP
snooping Querier.
