[Sysname-igmp-snooping] entry-limit 512
fast-leave (IGMP-snooping view)
Use fast-leave to enable fast-leave processing globally. With this function enabled, when the switch
receives an IGMP leave message on a port of the SAP module, it directly removes that port from the
multicast forwarding entry of the specific group.
Use undo fast-leave to disable fast-leave processing globally.
Syntax
fast-leave [ vlan vlan-list ]
undo fast-leave [ vlan vlan-list ]
Default
Fast-leave processing is disabled.
Views
IGMP-snooping view
Default command 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.
Usage guidelines
For a router that supports both IGMP snooping and IGMP and is installed with the SAP module, this
command takes effects in IGMP snooping-enabled VLANs and VLANs with IGMP-enabled VLAN
interfaces.
Examples
# Enable fast-leave processing for VLAN 2.
<Sysname> system-view
[Sysname] igmp-snooping
[Sysname-igmp-snooping] fast-leave vlan 2
