MLD Snooping Commands
This section describes commands used for MLD Snooping. In IPv4, Layer 2 switches can 
use IGMP Snooping to limit the flooding of multicast traffic by dynamically configuring Layer 2 
interfaces so that multicast traffic is forwarded only to those interfaces associated with IP 
multicast addresses. In IPv6, MLD Snooping performs a similar function. With MLD 
Snooping, IPv6 multicast data is selectively forwarded to a list of ports that want to receive 
the data, instead of being flooded to all ports in a VLAN. This list is constructed by snooping 
IPv6 multicast control packets.
Note:
This note clarifies the prioritization of MGMD Snooping 
Configurations. Many of the IGMP/MLD Snooping commands are 
available both in the Interface and VLAN modes. Operationally the 
system chooses or prefers the VLAN configured values over the 
Interface configured values for most configurations when the interface 
participates in the VLAN.
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), 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.
