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, starts 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 the 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 | The cost for a packet to travel from this port to the root in the current Spanning Tree |
Cost | configuration. The slower the media, the higher the cost. |
Designated | The priority and MAC address of the device through which this port must communicate |
Bridge(ID) | to reach the root of the Spanning Tree. |
Designated | The priority and number of the port on the designated bridging device through which this |
Port (ID) | switch must communicate with the root of the Spanning Tree. |
