Description: 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 stpDot1dStpPortEnable), this object will have a value of disabled(1).

What is stpDot1dStpPortState?

The port's current Spanning Tree Protocol state (disabled, blocking, listening, learning, forwarding, or broken), which controls what the port does with received frames; a malfunctioning port is placed in 'broken', while a disabled port shows 'disabled'.
