Field Description
Port
The port number of the port for which this entry contains Spanning Tree Protocol management information.
StgID
The STG identifier assigned to this port.
Priority
The value of the priority field which is contained in the first octet of the (2 octet long) Port ID. The other octet of the Port ID is given by the value of rcStgPort.
State
The port's current state as defined by the application of the Spanning Tree Protocol. This state controls what action a port takes on reception of the frame. If the bridge has detected a port that is malfunctioning, it will place that port into the Broken (6) state. For ports that are disabled, this object will have a value of disable.
EnableStp
The enabled/disabled status of the port.
FastStart
When this flag is set, the port is moved straight to the Forwarding (5) state upon being enabled.
PathCost
The contribution of this port to the path cost of paths toward the spanning tree root that includes this port. The 802.1D-1990 protocol recommends that the default value of this parameter be in inverse proportion to the speed of the attached LAN.
DesignatedRoot
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.
DesignatedCost
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.
DesignatedBridge
The Bridge Identifier of the bridge that this port considers to be the Designated Bridge for this port's segment.
DesignatedPort
The Port Identifier of the port on the Designated Bridge for this port's segment.
ForwardTransitions
The number of times this port has transitioned from the Learning state to the Forwarding state.
