4-4Bridge MIBdot1dStpPriority {dot1dStp 2}Integer Read-WriteThe value of the write-able portion of the Bridge ID, i.e., the firsttwo octets of the (8 octet long) Bridge ID. The other (last) 6 octets ofthe Bridge ID are given by the value of dot1dBaseBridgeAddress.Any value from 0 to 65535 may be specified.dot1dStpTimeSinceTopologyChange {dot1dStp 3}Time Ticks Read-OnlyThe time (in hundredths of a second) since the last time a topologychange was detected by the bridge entity.Zero if a topology change is in progress; otherwise, the time sincethe topology last stabilized.dot1dStpTopChanges {dot1dStp 4}Counter Read-OnlyThe total number of topology changes detected by this bridge sincethe management entity was last reset or initialized.dot1dStpDesignatedRoot {dot1dStp 5}Octet String Read-OnlyThe bridge identifier of the root of the spanning tree as determinedby the Spanning Tree Protocol as executed by this node. This valueis used as the Root Identifier parameter in all Configuration BridgePDUs originated by this node.dot1dStpRootCost {dot1dStp 6}Integer Read-OnlyThe cost of the path to the root as seen from this bridge.dot1dStpRootPort {dot1dStp 7}Integer Read-OnlyThe port number of the port which offers the lowest cost path fromthis bridge to the root bridge.
