A path alarm processing method and device perform an alarm mask designation for an ADMIN_STATUS object of a GMPLS path message used upon path setup, and an alarm mask release designation for unused bits of a Sub-TLV object additionally generated. When an alarm generation and its recovery are recognized during alarm monitoring, the alarm mask release designation is confirmed to release an alarm mask. As the above-mentioned alarm mask release designation, at least any one of a lapse of a fixed time by a timer after a path setup, a predetermined message indicating an alarm mask release, and a predetermined number of receptions of the predetermined message can be designated.
