Syntax
mld group-limit limit
undo mld group-limit
Default
The maximum number of IPv6 multicast groups that an interface can join is 4096.
Views
Interface view
Default command level
2: System level
Parameters
limit: Specifies the maximum number of IPv6 multicast groups that an interface can join. The value ranges
from 1 to 4096.
Usage guidelines
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.
Examples
# Allow GigabitEthernet 0/1 to join up to 128 IPv6 multicast groups.
<Sysname> system-view
[Sysname] interface gigabitethernet 0/1
[Sysname-GigabitEthernet0/1] mld group-limit 128

mld group-policy
Use mld group-policy to configure an IPv6 multicast group filter on the current interface to control the IPv6
multicast groups that the hosts on the current interface can join.
Use undo mld group-policy to remove the configured IPv6 multicast group filter.
Syntax
mld group-policy acl6-number [ version-number ]
undo mld group-policy
Default
No IPv6 multicast group filter is configured. That is, a host can join any valid IPv6 multicast group.
