An information processing apparatus includes: a memory; and a processor coupled to the memory and configured to: perform switching to a transmission device in a standby status of transmission devices in a redundant configuration when a transmission device under operation configuration fails; store, as normal coupling information, coupling information at a time when a network system, constituted by the information processing apparatus and the transmission devices, is normal, the coupling information being information on a transmission device port to which a communication control device is coupled; when the transmission device to which the communication control device is coupled is repaired or replaced, determine whether the coupling information transmitted from the transmission device after the repair or replacement matches with the normal coupling information; and control communications between the communication control device and the transmission device port to which the communication control device is coupled based on the determination result.
