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.
