Default level
2: System level
Parameters
limit: Specifies the maximum number of IPv6 multicast groups that an interface can join, in the range of
1 to 1000.
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 1000.
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.
You can also use the mld-snooping group-limit command to limit the number of IPv6 multicast groups
that an interface can join. However, if you configure the limit both in a VLAN and on a VLAN interface
of this VLAN by using these two commands, inconsistencies might exist between Layer 2 and Layer 3
table entries. Therefore, HP recommends you to configure the limit only on the VLAN interface.
Related commands: mld static-group, mld-snooping group-limit, and reset mld group.

# Allow VLAN-interface 100 to join up to 128 IPv6 multicast groups.
