Port State – Displays the current STP state of a port. If enabled, the port state determines
what forwarding action is taken on traffic. Possible port states are:
–
Forwarding – STP is enabled on the port, and the port is forwarding packets based on
the STP topology.
–
Disabled – STP is currently disabled on the port. The port forwards traffic while
learning MAC addresses.
–
Blocking – The port is currently blocked and cannot forward traffic or learn MAC
addresses. Blocking is displayed when STP is enabled.
–
Listening – The port is in Listening mode. The port cannot forward traffic nor can it
learn MAC addresses.
–
Learning – The port is in Learning mode. The port cannot forward traffic, however it
can learn new MAC addresses.

Multicast
Multicast forwarding allows a single packet to be forwarded to multiple destinations. L2 Multicast
service is based on L2 switch receiving a single packet addressed to a specific Multicast address.
Multicast forwarding creates copies of the packet, and transmits the packets to the relevant ports.
•
Registered Multicast traffic – If traffic addressed to a registered Multicast group is seen it is
handled by an entry in the Multicast Filtering Database and forwarded only to the registered
ports.
