User Guidelines
The IGMP snooping querier can be enabled on a VLAN only if IGMP snooping is
enabled for that VLAN.
At most one switch can be configured as an IGMP Querier for a VLAN.
When the IGMP snooping querier is enabled, it starts after a host-time-out/2 with
no IGMP traffic being detected from a Multicast router.
The IGMP Snooping Querier disables itself if it detects IGMP traffic from a
Multicast router. It restarts automatically after host-time-out/2.
Example
switchxxxxxx(config)# ip igmp snooping vlan 1 querier
