Spanning Tree Bridge Port Parameters (Continued)

 

 

State

Current bridging state of the port.

 

The options are:

 

Disabled - The port is disabled.

 

Blocking - The Spanning Tree algorithm has set this port’s

 

 

state to block, meaning that it is enabled, but not passing

 

 

traffic.

 

Listening - The port is in a transitional state, waiting for the

 

 

spanning tree algorithm to determine whether it should

 

 

block or forward traffic.

 

Learning - The port is learning MAC addresses, but not yet

 

 

forwarding traffic.

 

Forwarding - This port has been selected by the Spanning

 

 

Tree algorithm to forward traffic, and is forwarding traffic

 

 

currently.

 

Down - The port’s physical port has no link detected.

 

 

Designated Root

Displays the Root bridge for this spanning tree.

 

 

Designated Bridge

The bridge identifier for the bridge considered to be the

 

designated bridge for this segment.

 

 

Designated Port

The port identifier of the port on the designated bridge for this

 

segment of the spanning tree.

 

 

Designated Cost

The path cost of the designated root of the segment connected to

 

this port.

 

 

Forward

Number of times that this port has transitioned from blocking to

Transitions

forwarding.

 

 

 

4.In the Bridge Port column, click on the Bridge Port number to configure bridge port parameters. The Spanning Tree Port Configuration dialog box opens.

5.Use Table 12-6 to configure Spanning Tree Bridge Port Information parameters:

 

Table 12-6.Spanning Tree Bridge Port Information Parameters

 

 

 

Parameter

 

Definition

 

 

 

Enable

 

Sets whether or not spanning tree is active on this bridge port.

 

 

 

Priority

 

Sets the port’s priority in the spanning tree algorithm. A port

 

 

with a higher priority (lower priority number) is more likely to

 

 

be chosen as the primary path in the spanning tree.
