IGMP Snooping Immediate Leave

Normally, an IGMP snooping querier sends a group-specific or group-source-specific
query message upon receipt of a leave message from a host. If you want to set a leave
latency as 0 (zero), you can omit the querying procedure. When the querying procedure
is omitted, the switch immediately removes the entry from the forwarding table for that
VLAN, and informs the multicast router.
To enable the IGMP snooping immediate leave, use the following command.
Command
ip igmp snooping immediate-
leave
ip igmp snooping port PORTS
immediate-leave
ip igmp snooping vlan VLANS
immediate-leave
To disable the IGMP snooping immediate leave, use the following command.
Command
no ip igmp snooping immediate-
leave
no ip igmp snooping port
PORTS immediate-leave
no ip igmp snooping vlan
VLANS immediate-leave
Use this command with the explicit host tracking feature (see Section 9.2.3.6). If you don't,
when there is more than one IGMP host belonging to a VLAN, and a certain host sends a
leave group message, the switch will remove all host entries on the forwarding table from
the VLAN. The switch will lose contact with the hosts that should remain in the forwarding
table until they send join requests in response to the switch's next general query message.
