ipv6 mld limit

Use this command to configure a limit on the maximum number of group memberships
that may be learned. The limit may be set for the switch as a whole, or for a specific
interface.

Once the specified group membership limit is reached, all further local-memberships will
be ignored.

Optionally, an exception access-list can be configured to specify the group-address(es)
that are exempted from being subject to the limit.

Use the no variant of this command to unset the limit and any specified exception access-
list.

Syntax

ipv6 mld limit [except ]

no ipv6 mld limit

Default

The default limit, which is reset by the no variant of this command, is the same as
maximum number of group membership entries that can be learned with the ipv6 mld
limit
command.

The default limit of group membership entries that can be learned is 512 entries.

Mode

Global Configuration and Interface Configuration for a specified VLAN interface or a range
of VLAN interfaces.

Usage

This command applies to interfaces configured for MLD Layer-3 multicast protocols and
learned by MLD Snooping.

Examples

The following example configures an MLD limit of 100 group-memberships across all
VLAN interfaces on which MLD is enabled, and excludes groups in the range
ff1e:0db8:0001::/64

from this limitation:
