2: System level
Parameters
acl-number: Basic ACL number, in the range of 2000 to 2999. If you do not include this option in your
command, this command takes effect for all multicast groups.
Description
Use igmp fast-leave to configure fast-leave processing on the current interface.
Use undo igmp fast-leave to disable fast-leave processing on the current interface.
By default, fast-leave processing is disabled, and the IGMP querier sends IGMP group-specific queries or
IGMP group-and-source-specific queries after receiving an IGMP leave message from a host, instead of
sending a leave notification directly to the upstream.
The igmp fast-leave command cannot be used in VLAN-interface view. To enable fast-leave processing
on a specific Layer 2 port or ports, use the igmp-snooping fast-leave command or the fast-leave
(IGMP-snooping view) command.
The igmp-snooping fast-leave and fast-leave (IGMP-snooping view) commands are effective for both
IGMP snooping–enabled VLANs and VLANs with IGMP enabled on the corresponding VLAN
interfaces.
Related commands: fast-leave (IGMP view), fast-leave (IGMP-snooping view), igmp
last-member-query-interval, and igmp-snooping fast-leave.
