MLD Snooping Configuration
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 to only those
interfaces associated with IP multicast address. 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.
To globally enable MLD snooping on the switch:
1. Select Switch
ing Multicast MLD Snooping MLD Snooping Configuration.
2. Next to MLD Snooping Admin Mode, enable the administrative mode for MLD Snooping on
the switch.
3. Click App

MLD Interface Configuration
For MLD snooping to be active on an interface, it must be enabled both globally and on the
interface (physical or LAG).
To configure an interface for MLD snooping:
1. Select Switch
ing Multicast MLD Snooping Interface Configuration.
