bridgeDot1dStpPortState
Module: GANDALF-ENTERPRISE-MIB
OID (symbolic): GANDALF-ENTERPRISE-MIB::bridgeDot1dStpPortState

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 dot1dStpPortEnable), this object will have a value of disabled(1).
What is bridgeDot1dStpPortState?
Reports the port's current Spanning Tree Protocol state: disabled(1), blocking(2), listening(3), learning(4), forwarding(5), or broken(6) if the bridge has detected the port is malfunctioning; deprecated in favor of newer STP objects. Admins check this to see whether a port is actively passing traffic (forwarding) or being held back by spanning-tree logic (blocking/listening/learning), which explains why a link that's physically up may not yet be carrying data.
