The present invention discloses an integrated managing method for switching devices of Local Area Network, in which the switching device broadcasts applying register message including address identification of present switching device on the port connected to a managing device, the managing device turns to the operation of register after receiving the message, and sends back the register response message, the switching device sends handshake message to the managing device in timing after receiving a successful register response message, the managing device sends back the communicating response message, thus the operation of communicating between the managing device and the switching device is accomplished, if the switching device does not receive the communicating response message from the managing device within designated time, it indicates that communication is interrupted and the operation of register starts again; during the process of communicating, the managing device manages the switching device, the switching device sends back the response message to the managing device according to the operation result; IP addresses do not need to be assigned for the switching device in said scheme, thus integrated management and maintenance for network switching device are accomplished, and IP address resource of network is saved.
