Defining Unregistered Multicast Settings
Multicast frames are generally forwarded to all ports in the VLAN. If IGMP/MLD Snooping is enabled, the switch learns about the existence of Multicast groups, and monitors which ports have joined which Multicast group. Multicast groups can also be statically configured. Multicast groups that were either dynamically learned or statically configured, are considered registered.
The switch forwards Multicast frames (from a registered Multicast group) only to ports that are registered to that Multicast group.
The Unregistered Multicast page enables handling Multicast frames that belong to groups that are not known to the switch (unregistered Multicast groups). Unregistered Multicast frames are usually forwarded to all ports on the VLAN.
You can select a port to receive or filter unregistered Multicast streams. The configuration is valid for any VLAN of which it is a member (or will be a member).
This feature ensures that the customer receives only the Multicast groups requested and not others that may be transmitted in the network.
