A data upgrade method for a switching device in a two-layer network environment that reduces or eliminates the need to configure IP addresses for switching devices. A switching device sends a register request message to a managing device and the managing device executes a register operation to the message. After the register operation is finished successfully, the switching device shakes hands with the managing device. During the handshaking, the managing device sends a data description frame of the data to be upgraded to the switching device and the switching device determines whether to execute a data upgrade operation after receiving the message. If yes, the switching device sends a data description frame response message allowing data upgrade. The managing device receives the data description frame response message and the data to be upgraded is downloaded to the switching device.
