For the NE product, each device has a management IP address, and the NMS communicates with its management IP address to complete operations such as management, configuration, and maintenance of the device.

During the application of the prior art process, the following problems were found: During the project delivery phase, the network element device shipped to the project site is empty or the management IP address of the site is not in conformity with the planned management IP address, and the newly added network cannot be added.

When the network management server needs to query a disconnected network element, the network management server obtains its neighbor network element (that is, the current network element) according to the network topology, and the network management server sends a remote query to the neighbor network element.

S160: The current network element queries, according to the remote query message, whether the destination network element in the remote query message is a neighbor network element of the current network element, and if yes, sends the remote query to the destination network element. In other embodiments, further, if no, the remote query message is discarded.

S170: The current network element receives the query result returned by the destination network element, and sends the query result to the network management server, and receives the configuration and modification information returned by the network management server according to the query result, and the configuration and modification information.

The NE5 is initialized to the NE5 and the NE5 site is added to the NMS server for management.

The NE5 is a newly-received device on the production line or a device that has been relocated from another site. The management IP address is configured to be empty or its management IP address is not the NE address of the NE5 site.

The network element NE3 can automatically discover the newly added network element NE5, and apply for the corresponding management IP and initial configuration data to the network management server, and then use the PPP private extension protocol to send the management IP and initial configuration data to the NE NE5. The NE NE5 initializes the configuration operation. After the NE NE5 completes the initialization operation, the NE NE5 can be managed normally on the NMS server. After some time, the NE6 hardware installation is completed, the optical fiber connection is normal, the device is powered on, and the convenient open function is continued. NE5 The related data is set for the NE NE6, and the initialization operation of the NE6 is completed, thereby realizing the automatic management of the newly added device and the automatic issuance of the service, thereby reducing the complexity of the service opening, saving time and labor costs.

The network element NE2, the network element NE3, and the network element N E4 communicate with the network management unit through the network element NE1, if the network element NE2 In the event of a detachment, you can collect information by following these steps:

The network management server sends the remote query message to the NE NE1 by using the established link.

After receiving the remote query, the NE1 sends the remote query to the network element NE2.

The NE2 receives the remote query packet sent by the NE1, obtains its own data configuration, and returns it to the NE1.

The NE1 receives the data configuration of the NE1 and then returns it to the network management server using the established link.

The remote configuration is similar to the above process. The network management server sends configuration and modification information to the NE1 through the established link. The NE1 uses the PPP private extension protocol to communicate with NE2, and finally completes NE2 configuration.

The above are only the preferred embodiments of the present invention, and are not intended to limit the present invention. Any modifications, equivalents, and improvements made within the spirit and scope of the present invention should be included in the scope of the present invention. within.
