Configuring IP Multicast Switching
between IP multicast groups.) is disabled on a switch. The following subsections describe how to enable
and disable zapping by using the

Enabling the MLD Zapping

To enable MLD zapping on the system if no VLAN is specified, use the
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
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 (i.e., disabled).
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 (i.e., disabled).

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 will decide whether the
new MLD report will be dropped or will replace 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 member-
ship 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
group command as shown below:
-> ipv6 multicast max-group 25 action drop
