- vStpPriority
- The value of the write-able portion of the Bridge ID, i.e., the first two octets of the (8 octet long) Bridge ID (vStpBridgeAddress). The other (last) 6 octets of the Bridge ID are recommended to be the numerically smallest MAC address of all ports that ...

- The total number of topology changes detected by this spanning tree instance since the management entity was last reset or initialized.
- vStpDesignatedRoot
- The bridge identifier of the root of the spanning tree as determined by the Spanning Tree Protocol as executed by this instance. This value is used as the Root Identifier parameter in all Configuration Bridge PDUs originated by this node for this instance ...

- The cost of the path to the root as seen from this bridge for this spanning tree instance.

- The cost of the path to the root through the next best root port as seen from this bridge for this spanning tree instance.
- vStpNextBestRootPortNumber
- The port ifindex of the next port which offers the lowestcost path from this bridge to the root bridge for this spanning tree instance. This port will become root port if the actual root port goes down.
- vStpMaxAge
- 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 this spanning tree instance is currently using.
- vStpHelloTime
- The amount of time between the transmission of Configuration bridge PDUs by this instance 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 instance is curre ...
- vStpHoldTime
- This time value determines the interval length during which no more than two Configuration bridge PDUs shall be transmitted by this instance, in units of hundredths of a second.
- vStpForwardDelay
- 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 p ...
- vStpBridgeMaxAge
- 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 vStpBridgeHelloTime. The granularity of this timer is specified by 802.1D-1990 ...
- vStpBridgeHelloTime
- 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 nu ...
- vStpBridgeForwardDelay
- 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 vStpBridgeMaxAge. The granularity of this timer is specified by 802.1D-1 ...
- vStpPortTable
- A table that contains port-specific information for the Spanning Tree Protocol.
- vStpPortEntry
- A list of information maintained for every Spanning Tree instance by every port about the Spanning Tree Protocol state for that port.
- vStpPortNumber
- The port ifindex of the port for which this entry contains Spanning Tree Protocol management information.
- vStpPortPriority
- The priority of this port which used originally as part of the port ID specified in 802.1D.
- vStpPortState
- 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. For ports which are disabled (see vStpPortEnable), this object will have a value of disabled(1). Fal ...
- vStpPortEnable
- The enabled/disabled status of the port.
- vStpPortPathCost
- The contribution of this port to the path cost of paths towards the spanning tree root which include this port. 802.1D-1990 recommends that the default value of this parameter be in inverse proportion to the speed of the attached LAN.
- vStpPortDesignatedRoot
- 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.
- vStpPortDesignatedCost
- 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.

- The Bridge Identifier of the bridge which this port considers to be the Designated Bridge for this port's segment.
- vStpPortDesignatedPtPrio
- The priority portion of the port ID on the Designated Bridge for this port's segment.
- vStpPortDesignatedPtNumber
- The Port Identifier of the port on the Designated Bridge for this port's segment (defined in IEEE 802.1D-1998: Section 8.5.5.7).
- vStpPortForwardTransitions
- The number of times this port has transitioned from the Learning state to the Forwarding state.
- vStpPortManualMode
- The port's manual mode for this spanning tree instance. This mode defines the way the state of the port(vStpPortState) is managed. The mode can be dynamic (1) (managed by the Spanning Tree), or manual (blocking(2) or forwarding(3)). In manual mode, the po ...
- vStpPortRole
- The port's role for this spanning tree instance.
- vStpPortPrimaryPortNumber
- The port ifindex of the associated primary port for this spanning tree instance. This information is only available if the port role is backup (vStpPortRole = 4)
- vStpPortAdminConnectionType
- The administrative port's connection type for this spanning tree instance. This parameter is used to optimise the fast Spanning Tree (6.4.3 of P802.1w). The default value is nopointtopoint(1). The value pointtopoint(2) forces the port to be treated as if ...
- vStpPortOperConnectionType
- The operational port's connection type for this spanning tree instance.This parameter is used to optimise the fast Spanning Tree.
