To configure IGMP Snooping Port Group Filtering:
1. Click Configuration, IGMP Snooping, Port Group Filtering.
2. Click Add New Filtering Group to display a new entry in the table.
3. Select the port to which the filter will be applied.
4. Enter the IP address of the multicast service to be filtered.
5. Click Save.
MLD Snooping
Multicast Listener Discovery (MLD) snooping operates on IPv6 traffic and performs a similar
function to IGMP snooping for IPv4. That is, MLD snooping dynamically configures switch
ports to limit IPv6 multicast traffic so that it is forwarded only to ports with users that want to
receive it. This reduces the flooding of IPv6 multicast packets in the specified VLANs.
This switch supports MLD protocol version 1. MLDv1 control packets include Listener Query,
Listener Report, and Listener Done messages (equivalent to IGMPv2 query, report, and
leave messages).
Remember that IGMP Snooping and MLD Snooping are independent functions, and can
therefore both function at the same time.
Basic Configuration for MLD Snooping
Use the MLD Snooping Configuration page to configure global and port- related settings
which control the forwarding of multicast traffic. Based on the MLD query and report
messages, the switch forwards traffic only to the ports that request multicast traffic. This
prevents the switch from broadcasting the traffic to all ports and possibly disrupting network
performance.
If multicast routing is not supported on other switches in your network, you can use MLD
Snooping and Query to monitor MLD service requests passing between multicast clients and
servers, and dynamically configure the switch ports which need to forward multicast traffic.
Multicast routers use information from MLD snooping and query reports, along with a
multicast routing protocol such as PIMv6, to support IP multicasting across the Internet.
