Spanning Tree

The parameters shown in the following figure and table describe the current bridge STA Information.

Parameter

Description

Spanning Tree State

Shows if the switch is enabled to participate in an

 

STA-compliant network.

Bridge ID

A unique identifier for this bridge, consisting of bridge

 

priority plus MAC address (where the address is normally

 

taken from the agent).

Max Age

The maximum time (in seconds) a device can wait

 

without receiving a configuration message before

 

attempting to reconfigure.

Hello Time

The time interval (in seconds) at which the root device

 

transmits a configuration message.

Forward Delay

The maximum time (in seconds) the root device will wait

 

before changing states (i.e., listening to learning to

 

forwarding).

Designated Root

The priority and MAC address of the device in the

 

spanning tree that this switch has accepted as the root

 

device.

Root Port

The number of the port on this switch that is closest to

 

the root. This switch communicates with the root device

 

through this port. If there is no root port, then this switch

 

has been accepted as the root device of the spanning tree

 

network.

Root Path Cost

The path cost from the root port on this switch to the

 

root device.

Configuration Changes

The number of times the spanning tree has been

 

reconfigured.

Last Topology

The time since the spanning tree was last reconfigured.
