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.

For ports which are disabled (see aiDot1dStpPortEnable), this object will have a value of disabled(1).

What is aiDot1dStpPortState?

Reports a port's current Spanning Tree Protocol state (such as blocking, listening, learning, forwarding, or disabled/broken), which determines how the port handles received frames.
