H3C IE4300 Command Reference Manual page 1517

Parameters
vlan vlan-list
VLAN by its ID or a range of VLANs in the form of
ID is in the range of 1 to 4094. If you do not specify a VLAN, this command takes effect on all VLANs.
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
