Important Points to Remember for IGMP
Querier
• The IGMP snooping Querier supports version 2.
• You must configure an IP address to the VLAN interface for IGMP snooping Querier to begin. The IGMP
snooping Querier disables itself when a VLAN IP address is cleared, and then it restarts itself when an IP
address is reassigned to the VLAN interface.
• When enabled, IGMP snooping Querier does not start if there is a statically configured multicast router
interface in the VLAN.
• When enabled, IGMP snooping Querier starts after one query interval in case no IGMP general query
(with IP SA lower than its VLAN IP address) is received on any of its VLAN members.
• 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.
