Parameters
vlan vlan-list: Specifies a space-separated list of up to 10 VLAN items. Each item specifies a VLAN by its
ID or a range of VLANs in the form of start-vlan-id to end-vlan-id. The VLAN ID is in the range of 1 to
4094. If you do not specify any VLAN, the command takes effect on all VLANs.
Usage guidelines
This feature enables the switch to immediately remove the port that receives an IGMP leave message from
the forwarding entry for the multicast group specified in the message.
The configuration made in interface view is only effective on the current port and takes preference over
the global configuration.
Examples
# Enable IGMP snooping fast-leave processing on GigabitEthernet 2/1/1 in VLAN 2.
<Sysname> system-view
[Sysname] interface gigabitethernet 2/1/1
