PROBLEM TO BE SOLVED: To improve reliability by preventing an inequality from occurring in structural information between a network management device and a management object device. ;SOLUTION: When structural information of a management object device 30 is changed by a network management device, the management object device 30 informs the network management devices 10 and 10a of the changed structural information and when the network management devices 10 and 10a receive the structural information, they update the structural information stored in information storage parts 13 and 13a, display them on an information input and output part 11 and inform a network manager of the same. Thus, change in the structural information can be informed to the network manages who are in both the network management devices 10 and 10a, and the structural information within the two network management devices 10 and 10a are automatically made to be matched with each other.;COPYRIGHT: (C)1999,JPO
