changes between IP multicast groups.) is disabled on a switch. The following subsections describe how to
enable and disable zapping by using the
ipv6 multicast zapping command.
Enabling the MLD Zapping
To enable MLD zapping on the system if no VLAN is specified, use the ipv6 multicast zapping
command as shown below:
-> ipv6 multicast zapping enable
You can also enable MLD zapping on the specified VLAN by entering:
-> ipv6 multicast vlan 2 zapping enable
Disabling the MLD Zapping
To disable MLD zapping on the system if no VLAN is specified, use the ipv6 multicast zapping
command as shown below:
-> ipv6 multicast zapping disable
Or, as an alternative, enter:
-> ipv6 multicast zapping
To restore the MLD zapping to its default setting.
You can also disable MLD zapping on the specified VLAN by entering:
-> ipv6 multicast vlan 2 zapping disable
Or, as an alternative, enter:
-> ipv6 multicast vlan 2 zapping
To restore the MLD zapping to its default setting.
Limiting MLD Multicast Groups
By default there is no limit on the number of MLD groups that can be learned on a port/vlan instance. A
maximum group limit can be set on a port, VLAN or on a global level to limit the number of MLD groups
that can be learned. Once the configured limit is reached, a configurable action decides whether the new
MLD report is dropped or replaced an existing MLD membership.
The maximum group limit can be applied globally, per VLAN, or per port. Port settings override VLAN
settings, which override global settings.
If the maximum number of groups is reached an action can be configured to either drop the new
membership request or replace an existing group membership as show below.
Setting the MLD Group Limit
To set the MLD global group limit and drop any requests above the limit, use the ip multicast max-
group command as shown below:
-> ipv6 multicast max-group 25 action drop
