mSTPortPerMstState

Module: PRVT-MST-MIB

OID (symbolic): PRVT-MST-MIB::mSTPortPerMstState

OID (numeric): 1.3.6.1.4.1.738.1.5.107.1.4.2.1.3

Node type: OBJECT-TYPE

Type: INTEGER

Access: read-only

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 that are disabled (see mSTPortEnable), this object will have a value of disabled(1).

What is mSTPortPerMstState?

This read-only INTEGER reports a port's current spanning-tree state for one specific MST instance: disabled(1), blocking(2), listening(3), learning(4), forwarding(5), or broken(6) if the bridge detected the port malfunctioning; disabled ports (via mSTPortEnable) always show disabled(1) here.
