Status Displays current state of this port within the Spanning Tree:
Disabled No link has been established on this port. Otherwise, the port
has been disabled by the user or has failed diagnostics.
Blocking Port receives STA configuration messages, but does not
forward packets.
Listening Port will leave blocking state due to a topology change, start
transmitting configuration messages, but does not yet
forward packets.
Learning Port has transmitted configuration messages for an interval
set by the Forward Delay parameter without receiving
contradictory information. Port address table is cleared, and
the port begins learning addresses.
Forwarding The port forwards packets, and continues learning
addresses.
The rules defining port status are:
• A port on a network segment with no other STA-compliant bridging
device is always forwarding.
• If two ports of a switch are connected to the same segment and there
is no other STA device attached to this segment, the port with the
smaller ID forwards packets and the other is blocked.
• All ports are blocked when the switch is booted, then some of them
change state to listening, to learning, and then to forwarding.
Designated
Cost The cost for a packet to travel from this port to the root in the current
Spanning Tree configuration. The slower the media, the higher the cost.
Designated
Bridge (ID) The priority and MAC address of the device through which this port must
communicate to reach the root of the Spanning Tree.
Designated
Port (ID) The priority and number of the port on the designated bridging device
through which this switch must communicate with the root of the Spanning
Tree.

These menus display information on the ports that have been automatically learned via
GVRP and all those ports that have been configured by dynamic or static means to
forward VLAN traffic.
