What is oc3APSActiveSlot?

This read-only OID shows which physical slot is currently active and carrying live traffic for this APS pair—either the working slot or the protection slot. Operations teams check this during incidents to confirm which path is actively forwarding traffic and to verify that failover has or has not occurred. If the active slot is 4 instead of the normal working slot 3, it confirms that traffic has switched over to the protection port.
