usrBRStpPortState
Module: Usr-bridge-MIB
OID (symbolic): Usr-bridge-MIB::usrBRStpPortState
OID (numeric): 1.3.6.1.4.1.429.4.14.2.16.1.4
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. For ports which are disabled (see usrBRStpPortEnable), this object will have a value of disabled(1).
What is usrBRStpPortState?
This reports a port's current Spanning Tree state, which governs what it does with received frames: 'disabled(1)', 'on-demand-idle(2)', 'on-demand-initing(3)', 'blocking(4)', 'listening(5)', 'learning(6)', 'forwarding(7)', or 'broken(8)'; admins use this to see exactly where in the STP state machine a specific port currently sits, e.g. confirming a port is 'forwarding' and not stuck in 'blocking'.
