At a first port of a switch device of a motor vehicle, a device identifier of a device of the motor vehicle is received. An authenticity test on the basis of the device identifier is performed. If a test result of the authenticity test is positive, communication data of the device addressed to at least one further device of the motor vehicle are received at the first port and transmitted in a first VLAN of a communication network of the motor vehicle to the at least one further device. If the test result is negative, the communication data are rejected at the first port. A diagnostic inquiry for the device is received from a diagnostic device at a second port of the switch device. Independently of the test result the diagnostic inquiry is forwarded via the first port to the device in a second VLAN of the communication network.
