an IGMP query.
•Use
immediate leave only where there is just one host connected to a port.
Example

ip igmp snooping querier enable
The ip igmp snooping querier enable Interface Configuration mode command enables Internet Group
Management Protocol (IGMP) querier on a specific VLAN. Use the no form of this command to disable
IGMP querier on a VLAN interface.

User Guidelines
• IGMP snooping querier can be enabled on a VLAN only if IGMP snooping is enabled for that VLAN.
• No more than one switch can be configured as an IGMP Querier for a VLAN.
• When IGMP Snooping Querier is enabled, it starts after host-time-out/2 with no IGMP traffic
detected from a Multicast router.
• The IGMP Snooping Querier would disable itself if it detects IGMP traffic from a Multicast router. It
would restart itself after host-time-out/2.
