Example
The following example enables IGMP snooping on VLAN 2.
console#vlan database
console(config-vlan)#ip igmp snooping 2
ip igmp snooping fast-leave
This command enables or disables IGMP Snooping fast-leave mode on a
selected VLAN. Enabling fast-leave allows the switch to immediately remove
the layer 2 LAN interface from its forwarding table entry upon receiving an
IGMP leave message for that multicast group without first sending out MAC-
based general queries to the interface. The
no
form of this command disables
IGMP Snooping fast-leave mode on a VLAN.
You should enable fast-leave admin mode only on VLANs where only one host
is connected to each layer 2 LAN port. This setting prevents the inadvertent
dropping of the other hosts that were connected to the same layer 2 LAN port
but were still interested in receiving multicast traffic directed to that group.
Also, fast-leave processing is supported only with IGMP version 2 hosts.
Syntax
ip igmp snooping fast-leave
vlan-id
