Output Fields:

Field

Description

 

 

Port Id

The port number of the port for which this entry contains Spanning

 

Tree Protocol management information.

 

 

Priority

The value of the priority field which is contained in the most

 

significant 6 bits of the more significant octet of the (2 octet long)

 

Port ID. The least significant 2 bits of the more significant octet

 

and the less significant octet (total 10 bits) of the Port ID is given

 

by the value of dot1dStpPort.

 

 

State

The port's current state as defined by application of the Spanning

 

Tree Protocol. This state controls what action a port takes on

 

reception of a frame.

 

 

Port Status

The enabled/disabled status of the port.

 

 

Path Cost

The contribution of this port to the path cost of paths towards the

 

spanning tree root which include this port.

 

 

Desig Cost

The path cost of the Designated Port of the segment connected to

 

this port. This value is compared to the Root Path Cost field in

 

received bridge PDUs.

 

 

Desig Root

The unique Bridge Identifier of the Bridge recorded as the Root in

 

the Configuration BPDUs transmitted by the Designated Bridge

 

for the segment to which the port is attached.

 

 

Desig Bridge

The Bridge Identifier of the bridge which this port considers to be

 

the Designated Bridge for this port's segment.

 

 

Desig Port

The Port Identifier of the port on the Designated Bridge for this

 

port's segment.

 

 

Fwd Transitions

The number of times this port has transitioned from the Learning

 

state to the Forwarding state.

 

 

STP status

Spanning Tree Protocol to be enabled on the Bridge or not.

 

 

STP PacketsPrio

For STP PDUs, this priority shall be used for choice of traffic

 

class/ Queue on out¦going interface. In case the bridge port is

 

over an Aggregated ATM VC, this will also be used to identify the

 

VC, on which the packet is to be sent

 

 

Caution:

zThe specified interface should be an existing bridge interface.
