Object
column Enumeration
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 that are disabled (see ieee8021SpanningTreePortEnabled), this object will have a value of disabled(1). The values disabled, blocking, listening, and broken correspond to the Clause 12 port state of 'Discarding'. The value learning corresponds to the Clause 12 port state of 'Learning'. The value forwarding corresponds to the Clause 12 port state of 'Forwarding'.
