R3721-F3210-F3171-HP High-End Firewalls Network Management Command Reference-6PW101

539
Default level
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. Namely, 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.
Examples
# Enable fast-leave processing on GigabitEthernet 0/1.
<Sysname> system-view
[Sysname] interface gigabitethernet 0/1
[Sysname-GigabitEthernet0/1] igmp fast-leave
igmp group-limit
Syntax
igmp group-limit limit
undo igmp group-limit

Default level
2: System level
Parameters
limit: Maximum number of multicast groups that an interface can join. The value ranges from 1 to 4096.
Description
Use igmp group-limit to configure the maximum number of multicast groups that an interface can join.
Use undo igmp group-limit to restore the default.
The default upper limit is 4096.
This command is effective only for dynamically joined multicast groups but not statically joined multicast
groups.
If the configured limit value is smaller than the number of the existing multicast groups on the current
interface, the system does not automatically remove the multicast groups in excess. To bring this
configuration into effect in this case, you need to use the reset igmp group command to clear the IGMP
group information manually.
