Abstract: An integrated network element management system includes a client computer (6) and a master network element (7). The client computer includes a user interface (61) and an application (62). Various network elements may be displayed on the user interface in the form of icons that can be dragged by a user. The application performs configuration on a specific network element selected by the user on the user interface. The master network element communicatively connects with the client computer and a plurality of network elements. The master network element includes a topology information module for collecting topology information via the Topology Discovery Protocol, and for storing the topology information and configuration files of the network elements. A related integrated network element management method is also provided.
