Syntax
fast-leave [ vlan vlan-list ]
undo fast-leave [ vlan vlan-list ]
View
MLD-Snooping view
Default Level
2: System level
Parameters
vlan vlan-list: Defines one or multiple VLANs. You can provide up to 10 VLAN lists, by each of which
you can specify an individual VLAN in the form of vlan-id, or a VLAN range in the form of start-vlan-id to
end-vlan-id, where the end VLAN ID must be greater than the start VLAN ID. The effective range of a
VLAN ID is 1 to 4094.
Description
Use the fast-leave command to enable fast leave processing globally. With this function enabled, when
the switch receives an MLD leave message on a port, it directly removes that port from the forwarding
table entry for the specific group.
Use the undo fast-leave command to disable fast leave processing globally.
By default, fast leave processing is disabled.
Note that:
z This command works on MLD snooping–enabled VLANs.
z If you do not specify any VLAN, the command will take effect for all VLANs; if you specify a VLAN or
multiple VLANs, the command will take effect for the specified VLAN(s) only.
