Disclosed is an Ethernet switch control method for a vehicle for improving security when performing authentication on an external diagnostic device. The disclosed Ethernet switch control method for a vehicle may comprise the steps of: detecting a connection between a connector of a diagnostic device and a first port; establishing a connection between the diagnostic device and a control unit by referring to a virtual local area network (VLAN) ID table; establishing a connection between the control unit and an electronic control unit (ECU) in the vehicle by referring to the VLAN ID table; performing a certificate-based secure access procedure between the diagnostic device and the control unit; and switching a mode of an Ethernet switch from a locked mode to an unlocked mode, and establishing a connection between the diagnostic device and the ECU in the vehicle by referring to the VLAN ID table.
