his command applies to only the IGMP messages that the local switch generates when the switch or its
port acts as a member host, rather than those forwarded ones.

Default level
2: System level
Parameters
vlan
vlan-list
: Specifies one or multiple VLANs. You can provide up to 10 VLAN lists. For each list, 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 value range of a VLAN
ID is 1 to 4094. If you do not specify any VLAN, the command takes effect for all VLANs. If you specify
one or more VLANs, the command takes effect for the specified VLANs only.
Description
Use
fast-leave
to enable fast-leave processing globally. With this function enabled, when the switch
receives an IGMP leave message on a port, it directly removes that port from the multicast forwarding
entry of the specific group.
Use
undo fast-leave
to disable fast-leave processing globally.
By default, fast-leave processing is disabled.
This command works in both IGMP snooping–enabled VLANs and VLANs with IGMP enabled on their
VLAN interfaces.
