5. Enable MLD snooping for the
VLAN.
mld-snooping enable Disabled by default
Specifying the version of MLD snooping
Different versions of MLD snooping can process different versions of MLD messages:
• MLDv1 snooping can process MLDv1 messages, but flood MLDv2 messages in the VLAN instead
of processing them.
• MLDv2 snooping can process MLDv1 and MLDv2 messages.
If you change MLDv2 snooping to MLDv1 snooping, the system:
• Clears all MLD snooping forwarding entries that are dynamically created.
• Keeps static MLDv2 snooping forwarding entries (*, G).
• Clears static MLDv2 snooping forwarding entries (S, G), which will be restored when MLDv1
snooping is changed back to MLDv2 snooping.
For more information about static joining, see "Configuring static ports."

Configuring IPv6 static multicast MAC address entries
In Layer-2 multicast, a Layer-2 IPv6 multicast protocol (such as MLD snooping) can dynamically add IPv6
multicast MAC address entries. Or, you can manually configure IPv6 multicast MAC address entries.
Configuration guidelines
• The configuration that you make in system view is effective on the specified interfaces. The
configuration that you make in interface view or port group view is effective only on the current
interface or interfaces in the current port group.
• Any legal IPv6 multicast MAC address except 3333-xxxx-xxxx (where x represents a hexadecimal
number from 0 to F) can be manually added to the MAC address table. IPv6 multicast MAC
addresses are the MAC addresses whose the least significant bit of the most significant octet is 1.
