Variable Definitions

Variable Value
Port Specifies the port number.
State Specifies the port state in this RSTP instance. The port state is cataloged as discarding, learning, and forwarding.
Priority Specifies the value of the priority field which is in the first (in network byte order) octet of the (2 octet long) Port ID.
PathCost Specifies the contribution of this port to the cost of paths towards the spanning tree root.
ProtocolMigration Specifies the Protocol migration state of this port. Set this field to true to force the port to transmit RSTP BPDUs.

Note:

If this field is set to true, and the port receives an 802.1D type BPDU, the port again begins transmitting 802.1D BPDUs.

AdminEdgePort Specifies the administrative value of the Edge Port parameter. A value of true indicates that this port is assumed to be an edge-port and a value of false indicates that this port is assumed to be a nonedge-port.
OperEdgePort Specifies the operational value of the Edge Port parameter. The object is initialized to false on reception of a BPDU.
AdminPointToPoint

Specifies the administrative point-to-point status of the LAN segment attached to this port.

  • forceTrue—indicates that this port is always treated as being connected to a point-to-point link.
  • forceFalse—indicates that this port is treated as having a shared media connection.
  • auto—indicates that this port is considered to have a point-to-point link if it is an Aggregator and all of its members are aggregatable, or if the MAC entity is configured for full duplex operation, either through auto-negotiation or by management means.
OperPointToPoint Specifies the operational point-to-point status of the LAN segment attached to this port. This field indicates whether a port is considered to have a point-to-point connection. The value is determined by management or by autodetection.
Participating Specifies this field specifies whether a port is participating in the 802.1w protocol.
DesignatedRoot Specifies the bridge identifier of the old root of the Spanning Tree as determined by the Spanning Tree Protocol as executed by this node.
DesignatedCost Specifies 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 BPDUs.
DesignatedBridge Specifies the Bridge Identifier of the bridge which this port considers to be the Designated Bridge for this port segment.
DesignatedPort Specifies the Port Identifier for the port segment which is on the Designated Bridge.
ForwardTransitions Specifies the number of times this port has transitioned from the Learning state to the Forwarding state.
