Abstract: An NE management system and method using SNMP manages NEs and updates a management information list thereof without confusion even though NE settings are changed. The NE management system includes an NE and a management server. The NE generates NE settings in response to a setting change, transmits the NE settings to the management server, and receives a complete message from the management server. The management server receives the NE settings from the NE, acquires an element type of the NE based upon the received NE settings to determine an MIB to use, manages a registration list, and notifies the NE that a registration process is accomplished. The NE management method and system integrate registration and management of a plurality of NEs in a ubiquitous environment where various types and versions of the NEs exist together.
