If the bridge detects a port that is malfunctioning, it places that port into the broken state. For ports that are disabled (see EnableStp), this object has a value of disabled.
> PortEnable | The enabled/disabled spanning tree status of the port, that affects only the operation of the Spanning Tree Protocol on the port. Disabling STP at the spanning tree group takes precedence over what is configured here.
> PathCost | The contribution of this port to the cost of paths toward the spanning tree root, which include this port. The IEEE 802.1D-1990 standard 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.

It is recommended that this be the numerically smallest MAC address of all ports that belong to this bridge. However it is only required to be unique. When concatenated with rcStgPriority, a unique BridgeIdentifier is formed which is used in the Spanning Tree Protocol.
> NumPorts | The number of ports controlled by this bridging entity.
> ProtocolSpecification | An indication of what version of the Spanning Tree Protocol is being run. The value 'decLb100(2)' indicates the DEC LANbridge 100 Spanning Tree protocol.

> HelloTime | The amount of time between the transmission of Configuration bridge PDUs by this node on any port when it is the root of the spanning tree or trying to become so, in units of hundredths of a second. This is the actual value that this bridge is currently using.
> HoldTime | This time value determines the interval length during which no more than two Configuration bridge PDUs shall be transmitted by this node, in units of hundredths of a second.
> ForwardDelay | This time value, measured in units of hundredths of a second, controls how fast a port changes its spanning state when moving towards the Forwarding state. The value determines how long the port stays in each of the Listening and Learning states, which precede the Forwarding state. This value is also used, when a topology change has been detected and is underway, to age all dynamic entries in the Forwarding Database. (Note that this value is the one that this bridge is currently using, in contrast to rcStgBridgeForwardDelay which is the value that this bridge and all others would start using if/when this bridge were to become the root.)

The default value is 1500 (1500 seconds).
> BridgeMaxAge | The value in hundredths of a second that all bridges use for MaxAge when this bridge is acting as the root. Note: The 802.1D-1990 standard specifies that the range for this parameter is related to the value of dot1dStpBridgeHelloTime. The default is 2000 (20 seconds).
> BridgeHelloTime | Teh value in hundredths of a second that all bridges use for Hello Time when this bridge is acting as the root. The granularity of this timer as specified by the IEEE 802.1D-1990 standard, is increments of 1/100 of a second. The default is 200 (2 seconds).
