What is adnBoardSwitchCause?

This OID records the reason the last failover or failback occurred—whether it was manual, due to a fault, or planned maintenance. Engineers review this when investigating failover events to understand if the system responded correctly or if manual intervention triggered it. Values might include 0 (no switch), 1 (neither occurred yet), 2 (manual failover), or 3 (automatic due to fault detection).
