Description:
Selected Port Role of the port for this spanning tree instance.
What is jnxMIMstCistSelectedPortRole?
This object shows the current spanning tree role assigned to a specific network port (disabled, alternate, backup, root, or designated) within a Multiple Instance Spanning Tree instance. The port role determines its responsibility in the network topology, such as whether it blocks traffic to prevent loops (alternate/backup) or forwards traffic (designated/root). An operator uses this to understand each port's position in the spanning tree and verify proper network redundancy configuration.
