What is previousFirmwareVersion?
This read-only OID stores the version identifier of the firmware that was running before the most recent upgrade, which is kept available on the device for emergency rollback. If a new firmware causes problems, an admin can command a rollback to this previous version without re-downloading. For example, if the current version is 10.2.5 and this shows 10.2.3, the system can quickly revert to 10.2.3 if the upgrade destabilizes operations.
