Abstract: In an optical transmission device, firmware that operates within a CPU of a first LIU and firmware that operates within a CPU of a second LIU periodically measure a load status of a CPU via an OS, respectively. Switchover control of a master CPU is performed according to a load status of a CPU measured by the firmware of each LIU. For example, when a load status of the CPU of the second LIU is lower than that of the CPU of the first LIU, a master CPU that performs switchover control of a predetermined port is switched to a slave CPU in the first LIU, and a slave CPU related to the predetermined port is switched to a master CPU in the second LIU, thereby dynamically changing the setting.
