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

947
Default level
2: System level
Parameters
acl6-number: Number of a basic IPv6 ACL, in the range of 2000 to 2999. If you do not specify any IPv6
ACL number, this command takes effect for all IPv6 multicast groups.
Description
Use mld fast-leave to configure MLD fast-leave processing on the current interface.
Use undo mld fast-leave to disable MLD fast-leave processing on the current interface.
By default, MLD fast-leave processing is disabled. That is, the MLD querier sends
multicast-address-specific queries or multicast-address-and-source-specific queries after receiving an MLD
done message from a host, instead of sending a leave notification directly to the upstream.
Related commands: fast-leave and mld last-listener-query-interval.
Examples
# Enable MLD fast-leave processing on GigabitEthernet 0/1.

Default level

Parameters
limit: The maximum number of IPv6 multicast groups that an interface can join. The value ranges from 1
to 4096.
Description
Use mld group-limit to configure the maximum number of IPv6 multicast groups that an interface can
join.
Use undo mld group-limit to restore the default.
By default, the upper limit is 4096.
This command is effective only for dynamically joined IPv6 multicast groups but not statically joined IPv6
multicast groups.
If the configured limit value is smaller than the number of the existing IPv6 multicast groups on the current
interface, the system does not automatically remove the IPv6 multicast groups in excess. To bring this
configuration into effect in this case, you need to use the reset mld group command to clear the IPv6
multicast groups information manually.
