[0043] In view of the problems in the prior art of greatly wasting human resources, taking a long time and having low configuration efficiency, an embodiment of the present invention provides an automatic configuration method for a device, which is applied to a network management device included in a selected network, and the network management device is communicatively connected with each network device included in the selected network.

[0044] The selected network can be, but is not limited to, a minimalist optical network. As the focus of the network center shifts to business, the management and maintenance of a large number of access / aggregation switches has become a burden for network administrators. Therefore, we began to learn from operators and proposed a flat network construction plan, namely a minimalist optical network, as the market changes. From the network implementation level, the biggest change brought by minimalist optical is that the original [weak-current box access switch pulls the network cable to the indoor] has changed to [pulling the optical fiber from the machine room (building / floor switch) to the indoor switch, and then leading out the indoor network cable], referred to as light into the room. After light enters the room, the number of indoor switches will increase significantly, usually 3 to 6 times the number of traditional weak-current room access switches. Taking 1,000 indoor information points as an example, if a 24-port switch is installed in the weak-current room, 40 units are required; if an 8-port Aurora switch is installed indoors, 125 units are required, a significant increase in number. As the number of indoor Aurora switches continues to increase, the probability of equipment failure increases. When a device fails, the administrator needs to replace the old device with a new one and then configure the new device, which greatly wastes human resources, takes a long time, and has low configuration efficiency.

[0045] Based on the above problems, a device automatic configuration method is proposed. The process of this method is as follows: Figure 1 As shown, the execution steps are as follows:

[0046] S11: updating the obtained interconnection information of the selected device into the network topology map of the selected network.

[0047] The selected device connection information includes interconnection information of ports of at least two devices.

[0048] Based on the communication connection between each network device and the network management device in the selected network, the methods for obtaining the interconnection information of the selected devices may include the following three methods:

[0049] In the first method, after receiving a CPEWAN Management Protocol (CWMP) keep-alive message sent by a second network device among the network devices, device interconnection information of each uplink port of the second network device carried in the CWMP keep-alive message is obtained to obtain the interconnection information of the selected device.

[0050] Each network device in the selected network will periodically send a CWMP keep-alive message to the network management device. The keep-alive message contains the device interconnection information of the device's uplink port, which may specifically be the media access control (Simple Network Management Protocol, MAC) address and port of the connected device.

[0051] The second method is to receive a Simple Network Management Protocol (SNMP) trap message sent by a third network device among the network devices, obtain the device interconnection information of each downlink port of the third network device carried in the SNMP Trap message, and obtain the selected device interconnection information.

[0052] SNMP is a standard protocol designed specifically for managing network devices such as servers, workstations, routers, switches, etc. on Internet Protocol (IP) networks. It is an application layer protocol. After a network device discovers a MAC address learned from a downlink port, it will send an SNMP Trap message to the network management device. The SNMP Trap message carries the learned MAC address, which may include the terminal's MAC address and port.

[0053] The third method is to obtain a neighbor table of a fourth network device among the network devices to obtain interconnection information of the selected device.

[0054] Network devices can, but are not limited to, broadcast their own MAC addresses and ports through the Link Layer Discovery Protocol (LLDP) to facilitate the discovery of their neighbors and establish a neighbor table. Network management equipment can periodically obtain the neighbor table of each network device to update its own network topology.

[0055] It should be noted that the second network device, the third network device, the fourth network device and the first network device may be the same as or different from each other.

[0056] S12: Determine whether each port of each network device in the network topology diagram is connected to ports of two devices.

[0057] Since the network topology diagram is updated in S11, there may be a situation where one port of a network device is connected to the ports of two devices. This may be caused by replacing a device due to a failure. Therefore, it needs to be checked.

[0058] S13: If it is determined that the first port of the first network device among the network devices is connected to the ports of two devices, the device configuration information of the first device that is first updated to the network topology map among the two devices connected to the first port is sent to the second device that is later updated to the network topology map, so that the second device is configured according to the device configuration information of the first device.

[0059] If it is determined that the first port of the first network device in each network device is connected to the ports of two devices, it can be determined that the first device that was updated first to the network topology map among the two devices connected to the first port is replaced by the second device that was updated later to the network topology map. Since the network management device will save the device configuration information of each device in the network topology map, the device configuration information of the first device can be sent to the second device at this time, and the second device is configured according to the device configuration information of the first device, thereby realizing automatic configuration of the replaced device.

[0060] In this solution, after obtaining the interconnection information of the selected device, the network topology of the selected network can be updated first, and then the device can be configured based on the network topology of the selected network. The entire process can be completed without human participation. Compared with the existing method, it can greatly save human resources, reduce time consumption, and improve configuration efficiency.

[0061] Optionally, if each access device in each network device is connected to at least one terminal, the method further includes:

[0062] Determine whether the first device in the network topology diagram is connected to at least one terminal;

[0063] If it is determined that the first device in the network topology diagram is connected to at least one terminal, determining whether each port connected to the first device by at least one terminal in the network topology diagram is connected to ports of two devices;

[0064] If it is determined that the second port connected to the first device by the first terminal in the at least one terminal in the network topology diagram is simultaneously connected to the third port of the first device and the fourth port of the second device, the port configuration information of the third port is sent to the second device so that the second device configures the fourth port according to the port configuration information.

[0065] After the second device replaces the first device, if the second device is an access device in the selected network, the access device will generally be connected to multiple terminals, such as printers, projectors, cameras, etc. After the second device replaces the first device, the network cable of the second device may be blindly plugged, such as the terminal is connected to the Gi 0 / 1 port of the device before the replacement, and the terminal is connected to the Gi 0 / 2 port of the device after the replacement, resulting in the terminal not matching the port service after accessing the second device, ultimately affecting the normal use of the terminal.

[0066] At this time, it is necessary to further determine whether the first device in the network topology is connected to at least one terminal. If it is determined that the first device in the network topology is connected to at least one terminal, it is determined whether the ports connected to the first device in the network topology are connected to the ports of two devices. If it is determined that the second port connected to the first device in the first terminal of at least one terminal in the network topology is connected to the third port of the first device and the fourth port of the second device at the same time, it means that the first terminal has migrated from the third port to the fourth port. At this time, the port configuration information of the third port can be sent to the second device, so that the second device configures the fourth port according to the port configuration information. In this way, the port where the connected terminal has migrated can be automatically configured.

[0067] Optionally, the above method includes:

[0068] Deleting the interconnection information between the first port of the first network device and the first device in the network topology diagram;

[0069] And delete the interconnection information between the second port of the first terminal and the third port of the first device in the network topology diagram.

[0070] After completing the configuration of the above-mentioned replaced device and the configuration of the port where the terminal migrates, the interconnection information between the first port of the first network device and the first device, and the interconnection information between the second port of the first terminal and the third port of the first device, which are first updated to the network topology diagram, are useless information and can be directly deleted to ensure the accuracy of the network topology diagram.

[0071] The following example illustrates the automatic configuration method of the above device. Assume that before replacement, two terminals are connected to the network device SF-A, where terminal 1 is connected to the Gi0 / 1 port and terminal 2 is connected to the Gi0 / 3 port.

[0072] The configuration of port 1 of SF-A is as follows:

[0073]

[0074] Port 3 of SF-A is configured as follows:

[0075]

[0076] SF-A notifies the MAC addresses and ports of Terminal 1 and Terminal 2 to the network management device through SNMP Trap messages:

[0077] Announcement event 1:

[0078] 1. Terminal MAC address: 00:0e:c6:dd:de:ba

[0079] 2. Port: Gi0 / 1

[0080] 3. Action: Learning

[0081] Announcement event 2:

[0082] 1. Terminal MAC address: 00:0e:c6:dd:de:b6

[0083] 2. Port: Gi0 / 3

[0084] 3. Action: Learning

[0085] The network management device will update the port interconnection relationship between SF-A and terminal 1 and terminal 2 into the network topology diagram.

[0086] If SF-A fails and is replaced by SF-B, terminal 1 is connected to the Gi0 / 4 port of SF-B, and terminal 2 is connected to the Gi0 / 6 port of SF-B. SF-B notifies the MAC addresses and ports of terminal 1 and terminal 2 to the network management device through SNMP Trap messages:

[0087] Announcement event 1:

[0088] 1. Terminal MAC address: 00:0e:c6:dd:de:ba

[0089] 2. Port: Gi0 / 4

[0090] 3. Action: Learning

[0091] Announcement event 2:

[0092] 1. Terminal MAC address: 00:0e:c6:dd:de:b6

[0093] 2. Port: Gi0 / 6

[0094] 3. Action: Learning

[0095] The network management device will update the port interconnection relationship between SF-B and terminal 1 and terminal 2 into the network topology diagram.

[0096] After troubleshooting, it was found that terminal 1 migrated from Gi0 / 1 to Gi0 / 4, and terminal 2 migrated from Gi0 / 3 to Gi0 / 6. Therefore, it was necessary to send the configuration information of Gi0 / 1 to Gi0 / 4, and the configuration information of Gi0 / 3 to Gi0 / 6. After SF-B adjusted the port configuration, it was as follows:

[0097]

[0098] The configuration of Gi0 / 1 and Gi0 / 3 of SF-B remains unchanged. When there are terminals connected later, if they are old terminals, the configuration migration is performed according to the above rules; if they are new terminals, the configuration remains unchanged and the original port configuration is retained.

[0099] Based on the same inventive concept, an embodiment of the present invention provides an automatic configuration device for a device, which is applied to a network management device included in a selected network, and the network management device is communicatively connected with each network device included in the selected network. The structure of the device is as follows Figure 2 As shown, including:

[0103] In this solution, after obtaining the interconnection information of the selected device, the network topology of the selected network can be updated first, and then the device can be configured based on the network topology of the selected network.
