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 Access the switch on-network and
connected to the Internet on page 19 or Access the switch off-network on page 30.
The login page displays.
If the NETGEAR Business page displays, see Register and access the switch with your
NETGEAR account on page 34.
4. Enter one of the following passwords:
• After registration, enter the local device password.
By default, the local device password is password.
• If you previously managed the switch through the Insight app or Cloud portal, enter
the Insight network password for the last Insight network location.
For information about the credentials, see Credentials for the local browser interface on
page 32.
5. Click the Login button.
