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 a VLAN, this command takes effect on all VLANs and VSIs.
Usage guidelines
The fast-leave processing feature enables the device to immediately remove a port from the forwarding entry for a multicast group when the port receives a leave message.
You can enable fast-leave processing globally for all ports in IGMP-snooping view or for a port in interface view. For a port, the port-specific configuration takes priority over the global configuration.
Examples
# Globally enable fast-leave processing for VLAN 2.
<Sysname> system-view [Sysname] igmp-snooping [Sysname-igmp-snooping] fast-leave vlan 2
