LIMIT
ipv6 mld limit
Overview
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 device 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
<limitvalue>
[except
<IPv6-access-list-name>
]
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
