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.
A value of forceTrue indicates that this port is always treated as being connected to a point-to-point link.
A value of forceFalse indicates that this port is treated as having a shared media connection.
A value of 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
|
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.
