Configuring MLD Snooping

Use this page to enable Multicast Listener Discovery (MLD) snooping on the device and to view global status information. In IPv4, Layer 2 switches can use IGMP (Internet Group Management Protocol) 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 networks, MLD snooping performs a similar function. With MLD snooping, IPv6 multicast data is selectively forwarded to a list of ports intended to receive the data (instead of being flooded to all of the ports in a VLAN). This list is constructed by
