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 for a port in interface view or globally for all ports in
IGMP-snooping view. For a port, the port-specific configuration takes priority over the global
configuration.
Examples
# Enable fast-leave processing for VLAN 2 on GigabitEthernet 1/0/1.
<Sysname> system-view
[Sysname] interface gigabitethernet 1/0/1
