Setting Description
Port Number The number of the port for which information is
displayed.
Port Status The status of the port.
Enabled — the port is enabled and can receive and
forward packets.
Disabled — the port is disabled.
Port State The current state of the port.
Disabled — the port is disabled and cannot forward
packets; it does not participate in STP operation.
Listening — the port is preparing to forward packets
but has been temporarily blocked to prevent loop.
During the Listening state, BPDUs are transmitted,
received, and processed. The port is included in STP
calculations.
Blocking — the port is not forwarding packets in order
to prevent more than one active path on the network.
The port is included in STP calculations, and BPDUs
can be received, and processed.
Learning — the port is preparing to forward packets
but has been temporarily blocked to prevent a loop.
During this state the switch learns the addresses of all
error-free packets. The port is included in STP
calculations and BPDUs can be transmitted, received,
and processed.
Forwarding — the port is able to forward received
packets. BPDUs can also be transmitted, received, and
processed.
Port MAC Address The MAC address of the device connected to the port.
Port Priority The priority of the port. By changing the priority, you
can make the port more or less likely to become the
Root Port.
Port Path Cost The cost factor assigned to the port. The lower the
assigned port cost, the more likely the port is to be
accessed.
