Description: Current state of the Port Role Transition State Machine for this port in this spanning tree context.
What is jnxMIMstMstiPortRoleTransitionSemState?
This is a read-only integer showing the current state of the spanning tree role-transition state machine for one port in a Multiple Spanning Tree instance. It reflects whether a port is transitioning from blocked to forwarding state or vice versa to prevent bridging loops. An operator monitors this during topology changes to verify the port correctly transitions through learning state before forwarding traffic.
Examples
