RSTP Ports field descriptions

Use the data in the following table to use the RSTP Ports tab.

Name

Description

Port

Specifies a unique value, greater than zero, indicating the port number.

Priority

Specifies the value of the priority field.

PathCost

Specifies the contribution of this port to the path cost of paths towards the root that includes this port.

ProtocolMigration

Specifies a port to transmit RSTP BPDUs if operating in RSTP mode. Any other operation on this object has no effect, and RSTP mode returns false if read.

AdminEdgePort

Specifies the administrative value of the Edge Port parameter. A value of true indicates that this port is an edge-port, and a value of false indicates that this port is a nonedge-port.

OperEdgePort

Specifies the operational value of the Edge Port parameter. The object is initialized to the value of AdminEdgePort and is configured to false on reception of a BPDU.

AdminPointToPoint

Specifies the administrative point-to-point status of the LAN segment attached to this port. A value of forceTrue indicates that this port is treated as if it is 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 autonegotiation or by management means.

OperPointToPoint

Specifies the operational point-to-point status of the LAN segment attached to this port. It indicates whether a port is considered to have a point-to-point connection or not. The value is determined by management or by autodetection as described in the AdminPointToPoint object.

OperVersion

Indicates if the port is in MSTP mode, RSTP mode or STP-compatible mode. MSTP mode transmits MST BDUs, RSTP mode transmits RST BPDUs and STP-compatible transmits Config/TCN BPDUs.
