96 OIDs in Spanning Tree Root Port
This theme covers which port on a bridge currently has the lowest-cost path to the Spanning Tree, or MSTP/RSTP, root bridge, along with the root-bridge ID and path-cost values used to determine that. Admins check the root-port assignment to confirm traffic is flowing over the intended uplink rather than an unexpected backup path, and compare the reported root-bridge ID across switches to verify the whole topology agrees on which bridge is root. A root-port value that keeps changing, or a designated-root ID that's inconsistent between neighboring switches, both point to spanning-tree instability worth investigating before it causes a loop or an outage.
