Claim:
A method for managing network device data, wherein a TRAP message is sent to a network management system when a configuration operation is performed on a device, the method further comprises: configuring identifiers respectively for different types of device data at device side; storing the identifiers into a database, by the network management system, upon storing the device data; during TRAP message processing and timing data synchronization, comparing by the network management system the identifiers stored in the database with the corresponding identifiers sent from the device side, and performing by the network management system an update in the case of inconsistency in the identifiers, wherein the TRAP message contains information relevant to changed data, and wherein the information relevant to changed data comprises the changed device data and the identifier of the type to which the device data belongs; extracting, by the network management system, the identifier from the TRAP message; comparing the identifier with the corresponding device identifier stored in the database; and using the device data information contained in the TRAP message to update the data in the database, when the identifier extracted from the TRAP message is not consistent with the corresponding device identifier stored in the database.
