The invention discloses a method for realizing the management of multi-version network elements at local maintenance terminal. The method comprises the steps that: the content of the local maintenance terminal (LMT) is divided into version relevant part and version irrelevant part according to service relativities thereof, and the LMT version relevant parts are packaged into dynamic library of version relevant parts; and the LMT installation package supporting multi-version network elements is divided, made and installed according to the LMT version, and the corresponding relationship betweennetwork element version and the LMT version is arranged in an installed list; when the LMT is accessed to a network element, the LMT can automatically acquire the version number of the present network element and automatically upload the dynamic library of version relevant part of LMT version corresponding to the network element version according to the version number of the network element. The invention also discloses a device for realizing the management of multi-version network elements at local maintenance terminal. By adopting the method and the device of the invention, the LMT version and the network element version can be self adapting and disc space occupied by the LMT version can be saved.
