SETTING DEVICE AND ON-VEHICLE APPARATUS

An SDN controller controls communication settings of SDN switches of a vehicle on-board network. The SDN controller includes a memory that stores multiple types of configuration information to which unique identifiers are respectively assigned. The SDN controller executes an acquisition process, a selecting process, and an updating process when a new vehicle on-board device is connected to the vehicle on-board network. The acquisition process is a process that acquires, from outside, an identifier corresponding to the vehicle on-board device to be newly connected. The selecting process is a process that selects the configuration information corresponding to the identifier acquired in the acquisition process from the multiple types of configuration information stored in the memory. The updating process is a process that updates the communication settings of the SDN switch based on the configuration information selected in the selecting process.
