Manage MLD snooping
In IPv6 networks, Multicast Listener Discovery (MLD) snooping performs a similar function as
IGMP does in IPv4 networks. With MLD snooping, IPv6 multicast data is selectively
forwarded to ports that are configured to receive the data, instead of being flooded to all ports
in a VLAN. The ports are determined by snooping IPv6 multicast control packets.
A multicast listener is a device that is configured to receive IPv6 multicast packets. MLD is
used by IPv6 multicast routers to discover the presence of multicast listeners on its
directly-attached links and to discover which multicast packets are of interest to neighboring
devices.
The MLD protocol is derived from IGMP. MLD version 1 (MLDv1) is equivalent to IGMPv2,
and MLD version 2 (MLDv2) is equivalent to IGMPv3. MLD is a subprotocol of Internet
Control Message Protocol version 6 (ICMPv6), and MLD messages are a subset of ICMPv6
messages, identified in IPv6 packets by a preceding Next Header value of 58.
Enable MLD snooping
You can enable MLD snooping, which is used to build forwarding lists for multicast traffic.
To enable MLD snooping:
1.
Connect your computer to the same network as the switch.
You can use a WiFi or wired connection to connect your computer to the network, or
connect directly to a switch that is off-network using an Ethernet cable.
2.
Launch a web browser.
3.
In the address field of your web browser, enter the IP address of the switch.
If you do not know the IP address of the switch, see
