A switch device includes: a plurality of communication ports; a switch unit configured to relay a frame, which has been transmitted from a function unit and to which information including an ID of a VLAN and priority information is added, to another function unit via a communication port, according to the priority information; and a duplication unit configured to, when the diagnosis device is connected to another switch device, duplicate the frame to be relayed via a designated communication port, thereby generating a duplicate frame for diagnosis. The duplication unit is able to set the priority information to be added to the duplicate frame for diagnosis, separately from the priority information to be added to the frame as an original. The switch unit outputs the duplicate frame for diagnosis, from a communication port corresponding to the other switch device, according to the priority information set by the duplication unit.
