set mld

This command enables MLD Snooping on the system (Global Config Mode) or an Interface (Interface Config Mode). This command also enables MLD Snooping on a particular VLAN and enables MLD Snooping on all interfaces participating in a VLAN.

If an interface has MLD Snooping enabled and you enable this interface for routing or enlist it as a member of a port-channel (LAG (Link Aggregation Group)), MLD Snooping functionality is disabled on that interface. MLD Snooping functionality is re-enabled if you disable routing or remove port channel (LAG) membership from an interface that has MLD Snooping enabled.

MLD Snooping supports the following activities:

  • Validation of address version, payload length consistencies and discarding of the frame upon error.
  • Maintenance of the forwarding table entries based on the MAC address versus the IPv6 address.
  • Flooding of unregistered multicast data packets to all ports in the VLAN.
