In order to solve the problem that the status update of the device in the prior art is not timely and inaccurate, the present invention provides a method and device for updating the state of the device. The present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It is understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to be limiting.

In the monitored device, due to the limitation of the number of Internet Protocol (IP) addresses in the Dynamic Host Configuration Protocol (DHCP) address pool, the IP address of the NMS assigned to the device will be Reuse, the device of the same IP address exists in the network management system. In the embodiment of the present invention, among the devices with the same IP address, the device state that has obtained the latest IP address is online, and the device state that has obtained the IP before. Real-time or regular batch settings are offline.

This embodiment provides a method for updating a device state. FIG. 1 is a flowchart of a method for updating a device state according to an embodiment of the present invention. As shown in FIG. 1, the method includes the following steps (step S102-step S104) :

Through the above method, for a plurality of devices having the same IP address, the device state of the device that newly obtained the IP address is kept online, and the device state of the other device is set to the offline state. The invention solves the problem that the device status update is not timely and inaccurate in the related art. The present invention is efficient and simple to implement, and does not need to poll the device, and only needs to count the devices of the same IP address in the system to determine the status of the devices as offline. Ordinary update SQL can achieve state updates.

In the embodiment of the present invention, after the first device obtains a new IP address on the DHCP server side, the first device sends the network management to the network management system. The network management system can usually be processed in two ways:

The first way: Real-time update mode. After the first device reports the new IP address, the DHCP server is immediately triggered to find multiple devices of the same IP in the system, and the status of the devices other than the first device is updated to the offline state. , thereby achieving accurate monitoring of the device status from the online state to the offline state;

The second way: Cycle batch update mode. After the network management system enables a task and calculates the older devices in the same IP address, the offline status update function is implemented in batches. This method is applicable to the case where the real-time performance of the status monitoring is not high, because it is batch processing, compared with the first type. The way is much more efficient.
