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. IEEE 802.1d implementations will return 'ieee8021d(3)'. If future versions of the IEEE Spanning Tree Protocol are released that are incompatible with the current version a new value will be defined. Enumerations: unknown (1) decLb100 (2) ieee8021d (3)
Priority
The value of the write-able portion of the Bridge ID, i.e., the first two octets of the (8 octet long) Bridge ID. The other (last) 6 octets of the Bridge ID are given by the value of dot1dBaseBridgeAddress. Range: 0 to 65535
TimeSinceTopologyChange
The time (in hundredths of a second) since the last time a topology change was detected by the BRICK.
TopChanges
The total number of topology changes detected by the BRICK since the management entity was last reset or initialized.
DesignatedRoot
The bridge identifier of the root of the spanning tree as determined by the Spanning Tree Protocol as executed by the BRICK. This value is used as the Root Identifier parameter in all Configuration Bridge PDUs originated by this BRICK.
RootCost
The cost of the path to the root as seen from the BRICK.
RootPort
The port number of the port which offers the lowest cost path from this bridge to the root bridge.
MaxAge
The maximum age of Spanning Tree Protocol information learned from the network on any port before it is discarded, in units of hundredths of a second. This is the actual value that the BRICK is currently using.
HelloTime
The amount of time between the transmission of Configuration bridge PDUs by the BRICK 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 currently being used.
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 under way, to age all dynamic entries in the Forwarding Database. [Note that this value is the one that is currently being used, in contrast to dot1dStpBridgeForwardDelay which is the value that this BRICK and all others would start using if/when this BRICK were to become the root.]
BridgeMaxAge
The value that all bridges use for MaxAge when this bridge is acting as the root. Note that 802.1D-1990 specifies that the range for this parameter is related to the value of dot1dStpBridgeHelloTime. The granularity of this timer is specified by 802.1D-1990 to be 1 second. An agent may return a badValue error if a set is attempted to a value which is not a whole number of seconds. Range: 600 to 4000
BridgeHelloTime
The value that all bridges use for HelloTime when this bridge is acting as the root. The granularity of this timer is specified by 802.1D-1990 to be 1 second. An agent may return a badValue error if a set is attempted to a value which is not a whole number of seconds. Range: 100 to 1000
BridgeForwardDelay
The value that all bridges use for ForwardDelay when this bridge is acting as the root. Note that 802.1D-1990 specifies that the range for this parameter is related to the value of dot1dStpBridgeMaxAge. The granularity of this timer is specified by 802.1D-1990 to be 1 second. An agent may return a badValue error if a set is attempted to a value which is not a whole number of seconds. Range: 400 to 3000
BridgePPPForwardDelay
This is the forward delay for PPP interfaces. Range: 100 to 3000
