ABSTRACT:
A network management system includes a main network management station and a backup network management station. Different physical and logic addresses are assigned to the two stations. The data packet(s) containing network management information has/have the physical and logical addresses assigned to the main network management station. Thus, only the main network management station can receive the data packet(s) containing network management information when it is in a proper operational condition. When the main network management station is about to fail, a packet (or packets) containing operational status information is/are sent to the backup network management work station, via a network. Upon receiving the operational status information, the physical and logical addresses assigned to the backup network management work station is modified as the physical and logical addresses assigned to the main network management station. Thus, the backup network management station can receive the data packet(s) containing the network management information after the main network management station has failed.
