Variable | Value |
---|---|
Port | The port number. |
State | Used to identify a port state in this RSTP instance. The port state is cataloged as discarding, learning, and forwarding. |
Priority | The value of the priority field which is contained in the first (in network byte order) octet of the (2 octet long) Port ID. |
PathCost | The contribution of this port to the cost of paths towards the spanning tree root. |
ProtocolMigration | Indicates 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 | 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 | The operational value of the Edge Port parameter. The object is initialized to false on reception of a BPDU. |
AdminPointToPoint |
The administrative point-to-point status of the LAN segment attached to this port.
|
OperPointToPoint | 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 auto-detection. |
Participating | This field specifies whether a port is participating in the 802.1w protocol. |
DesignatedRoot | The bridge identifier of the old root of the Spanning Tree as determined by the Spanning Tree Protocol as executed by this node. |
DesignatedCost | 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 | The Bridge Identifier of the bridge which this port considers to be the Designated Bridge for this port segment. |
DesignatedPort | The Port Identifier for the port segment which is on the Designated Bridge. |
ForwardTransitions | The number of times this port has transitioned from the Learning state to the Forwarding state. |
