Parameters
vlan vlan-list: Specifies a space-separated list of up to ten 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 this option is not specified, this command takes effect for all VLANs.
Usage guidelines
When an IGMP leave message arrives at a port that has the IGMP snooping fast-leave processing
feature enabled, the switch immediately removes that port from the forwarding entry for the multicast
group specified in the message.
The global configuration takes effect on all ports, but has a lower priority than the configuration made on
a specific port.
Examples
# Enable IGMP snooping fast-leave processing for VLAN 2.
<Sysname> system-view
[Sysname] igmp-snooping
[Sysname-igmp-snooping] fast-leave vlan 2
