IfIndex
The value of the instance of the ifIndex object defined in MIB-II, for the interface corresponding to this port.
Number
The number of the port. Range: 1 to 255
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. The other octet of the Port ID is given by the value of dot1dStpPort. Range: 0 to 255
State
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. If the bridge has detected a port that is malfunctioning it will place that port into the broken(6) state. For ports which are disabled (see dot1dStpPortEnable), this object will have a value of disabled(1). Enumerations: disabled (1) blocking (2) listening (3) learning (4) forwarding (5) broken (6)
Enable
The enabled/disabled status of the port.At least two ports must be enabled for bridging to be possible. Enumerations: enabled (1) disabled (2)
PathCost
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. Range: 1 to 65535
DesignatedRoot
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.
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 bridge PDUs.
DesignatedBridge
The Bridge Identifier of the bridge which this port considers to be the Designated Bridge for this port's segment.
DesignatedPort
The Port Identifier of the port on the Designated Bridge for this port's segment. Range: 1 to 65535
ForwardTransitions
The number of times this port has transitioned from the Learning state to the Forwarding state.
BackupForIfIndex
May be used to represent a backup interface. Its value is the IfIndex of the regular used interface. A dialup of the backup interface is only triggered, if the regular interface has stopped forwarding.
