4. Click Search. The status of all ports/LAGs are displayed.
5. Define how each port/LAG handles Multicast streams.
•
Static — The port receives all Multicast streams.
•
Forbidden — Ports cannot receive any Multicast streams, even if IGMP snooping
designated the port to join a Multicast group.
•
None — The port is not currently a Forward All port.
6. Click Apply. The Running Configuration file is updated.
Unregistered Multicast
Multicast frames are generally forwarded to all ports in the VLAN. If IGMP Snooping is enabled,
the device 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 device 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 device (unregistered Multicast groups). Unregistered Multicast frames are
usually forwarded to all ports on the VLAN.
