The invention relates to a method for searching
network element equipment and establishing topologic connection in a
network management system, which includes that any
network element equipment discovers adjacent
network element equipment by the communication protocol between equipment and stores the positioning information thereof;
custom instruction launches searching, and the
network management server (11) transmits the protocol packet in the fixed format to the network element equipment related to the
custom instruction; the network element equipment queries the information and transmits the responsive protocol packet; the
network management server (11) analyzes the responsive protocol packet and establishes the logically-corresponding entity of new network element equipment; new searching branches are established by the new network element equipment until that that the
custom instruction finally presents the result at the
client end (13) is accomplished. The method disperses the memory information, the information of automatic neighbor discovery of network element equipment and the information of adding memory topologic connection etc. within all network element equipment, realizes the rapid and efficient searching and enhances the reliability of the searching results, saves
data processing time and memory space, and has a plurality of
modes of entire network and designated network element equipment and a function of searching topologic connection.
