The embodiments of the present disclosure provide a method for managing network devices, and the method is applied among network devices, management devices, cloud managers, and domain name servers. In the embodiment of the present disclosure, the network device is connected to the management device in the local area network as an example for description. Referring to Figure 5, the method includes:

Step 501: The network device receives the assigned IP address.

The network device is any network device in the network management system. When the network device is connected to the management device in the local area network, the network device sends an assignment request to the DHCP server, where the assignment request is used to request the DHCP server to assign an IP address to the network device. The DHCP server receives the assignment request sent by the network device, selects an unused IP address from the address pool, assigns the selected IP address to the network device, and sends the IP address to the network device. The network device receives the IP address sent by the DHCP server, and stores the IP address in a non-volatile memory.

The DHCP server is configured with an address pool in advance, and the address pool includes multiple IP addresses. Multiple IP addresses in the address pool can be one continuous IP address segment or multiple consecutive IP address segments. When the multiple IP addresses in the address pool are a continuous IP address segment, the DHCP server may only store the starting IP address and the ending IP address of the address pool.

Step 502: The network device sends a registration request including the IP address of the network device to the cloud manager.

Before the network device sends the registration request to the cloud manager, the network device determines whether there is an IP address assigned last time by the network device or whether the IP address assigned last time is the same as the IP address. When the network device does not have the IP address assigned last time by the network device or the IP address assigned last time is different from the IP address, the network device sends a registration including the IP address of the network device to the cloud manager ask.

In this step, since the network device is connected to the management device in the local area network, the network device does not have the IP address assigned last time; therefore, the network device needs to be registered in the cloud manager. The network device sends a registration request including the IP address of the network device to the cloud manager. The registration request may also carry a media access control (English: Media Access Control, MAC) address of the network device.

Step 503: The cloud manager receives the registration request including the IP address of the network device sent by the network device, and allocates a domain name to the network device after the network device completes the registration.

The cloud manager receives the registration request, obtains the IP address of the network device from the registration request, and sends a registration response to the network device according to the IP address of the network device. connect. The cloud manager stores the IP address of the network device, thereby completing the registration of the network device. When the registration request also carries the MAC address of the network device, the cloud manager obtains the MAC address of the network device from the registration request.

After the network device completes the registration, the cloud manager assigns a domain name to the network device. The cloud manager includes a DNS component. Correspondingly, the step of assigning a domain name to the network device by the cloud manager may be: the cloud manager assigns a domain name to the network device through the DNS component. The DNS component stores a preset domain name planning rule, and the DNS component allocates a domain name to the network device according to the preset domain name planning rule.

The preset domain name planning rules can be set and changed as needed. In the embodiment of the present disclosure, the preset domain name planning rules are not specifically limited. For example, the preset domain name planning rule may be: "prefix + site name + suffix". Among them, the "prefix" can be the system name (sysname) of the network device, the "site name" can be the name of the physical location of the network device, and the "suffix" can be the domain name plan of the network device; for example, the domain name plan is "enterpriseA. com".

After the cloud manager assigns the domain name to the network device, the cloud manager stores the correspondence between the domain name and the IP address of the network device, so that the subsequent cloud manager can determine whether the current IP address of the network device has changed based on the domain name. Moreover, when the registration request carries the MAC address of the network device, the cloud manager may also store the correspondence between the MAC address of the network device and the domain name.

The cloud manager sends a storage instruction to the network device according to the IP address of the network device, the storage instruction carries the domain name, and the storage instruction is used to instruct the network device to store the domain name in a domain name file. The network device receives the storage instruction, obtains the domain name of the network device from the storage instruction, and stores the domain name in the domain name file of the network device according to the storage instruction. In addition, after the network device receives the domain name, the network device stores the correspondence between the IP address of the network device and the domain name.

Step 504: The cloud manager sends the corresponding relationship between the domain name of the network device and the IP address of the network device to the domain name server.

Before the cloud manager sends the corresponding relationship between the domain name of the network device and the IP address of the network device to the domain name server, the cloud manager determines whether there is an IP address assigned last time of the network device or the IP address and IP address assigned last time locally. Whether the IP address is the same. When the last IP address assigned to the network device does not exist locally in the cloud manager or the IP address assigned last time is different from the IP address, the cloud manager sends the domain name of the network device and the network device's domain name to the domain name server. Correspondence between IP addresses.

In this step, since the network device is connected to the management device in the local area network, there is no IP address assigned last time in the cloud manager. Therefore, the cloud manager sends a first domain name system (English: Domain Name System, DNS) message whose message type is added to the domain name server, and the first DNS message carries the domain name of the network device and the IP address of the network device corresponding relationship.

Step 505: The domain name server receives the correspondence between the domain name of the network device and the IP address of the network device sent by the cloud manager, and stores the correspondence between the domain name and the IP address of the network device.

The domain name server receives the first DNS message sent by the cloud manager, obtains the correspondence between the domain name of the network device and the IP address of the network device from the first DNS message, and stores the domain name of the network device and the IP address of the network device. The corresponding relationship of the addresses is convenient to resolve the IP address of the network device from the domain name server when the management device communicates with the network device subsequently.

The above steps 501-505 are the process of registering the network device in the cloud manager. The management device can manage the network device through the following steps 506-509.

Step 506: The management device probes at least one IP address in the address pool to determine an IP address that has been used.

The management device can detect the IP addresses in the address pool at preset intervals to determine the IP addresses that have been used; the management device can also detect the network topology of the network management system, and only when it detects that the network topology changes. Probe the IP addresses in the address pool to determine the IP addresses that have been used. Wherein, the management device includes a physical port for indicating whether the network topology changes; when the network topology changes, the physical port sends a notification message to the management device. When the management device receives the notification message, it is determined that the network topology has changed. The preset interval can be set and changed as required, for example, the preset interval can be 10 minutes or 1 hour, etc.

The user configures an address pool on the management device in advance, and the address pool includes multiple IP addresses. In this step, the management device may probe each IP address included in the address pool to determine the IP address that has been used.

Since the network management system includes new network devices and traditional network devices, the IP addresses of the new network devices are dynamically allocated by the DHCP server, while the IP addresses of the traditional network devices are static. That is, the IP address of the new network device may be changed due to the restart of the network device, while the IP address of the traditional network device will not be changed due to the restart of the network device. Therefore, in this step, the management device may not detect all the IP addresses in the address pool, but only detect other IP addresses except the known used IP addresses. Known used IP addresses include statically configured IP addresses, recently detected used IP addresses, and/or IP addresses recently resolved from domain name servers. This not only saves resources, but also improves efficiency. Correspondingly, this step can be:

The management device determines other IP addresses in the address pool except the known used IP addresses, and detects the other IP addresses to determine the used IP addresses.

When the management device communicates with the network device, the management device needs to resolve the IP address of the network device from the domain name server, and the management device stores the IP address of the network device and the time stamp for resolving the IP address. Correspondingly, when the known used IP addresses include the IP addresses recently resolved from the domain name server, the management device determines other IP addresses in the address pool except the known used IP addresses as follows:

The management device obtains the IP address resolved within the first preset duration closest to the current time, and determines other IP addresses in the address pool except the IP addresses that have been resolved. The first preset duration can be set and changed as required, and the first preset duration is not specifically limited in this disclosure; for example, the first preset duration can be 30 minutes or 1 hour.

In this step, the statically configured IP address is stored in the management device; correspondingly, when the known used IP address includes the statically configured IP address, the management device determines that the known used IP address is excluded from the address pool. The steps of the other IP addresses may be: the management device obtains the statically configured IP addresses, and determines other IP addresses except the statically configured IP addresses in the address pool.

When the management device detects the IP address that has been used, the management device stores the IP address and the detection time of the IP address. Correspondingly, when the known used IP addresses include the recently detected used IP addresses, the step of the management device determining other IP addresses in the address pool other than the known used IP addresses may be: management The device obtains the IP addresses detected within the second preset duration closest to the current time, and determines other IP addresses in the address pool except the IP addresses detected within the second preset duration closest to the current time.

The second preset duration and the first preset duration may or may not be equal. In addition, the second preset duration can be set and changed as required, and the second preset duration is not specifically limited in the present disclosure; for example, the second preset duration is equal to the first preset duration, both being 30 minutes or 1 hours and so on.

Before this step, the user configures the address pool on the management device. For any IP address, the management device probes the IP address based on the Ping operation. The step of detecting the IP address by the management device may be: the management device sends a scan signal to the network device using the IP address. When the IP address is used, the network device using the IP address returns an IP data packet to the management device, and the IP data packet includes the IP address of the network device. When the IP address is not used, no network device returns an IP data packet to the management device. If the management device receives the IP data packet returned by the network device within a third preset time period after sending the scan signal, the management device determines that the IP address has been used. If the management device does not receive the IP data packet returned by the network device within a third preset time period after the management device sends the scan signal, the management device determines that the IP address is not used.

In the embodiment of the present disclosure, the management device automatically acquires the IP addresses that have been used based on IP address scanning. Therefore, the IP address of the network device can be obtained without manual input. Human resources are saved and accuracy is improved. The third preset duration can be set and changed as required, and in this embodiment of the present disclosure, the third preset duration is not specifically limited. For example, the third preset duration may be 1 second or 0.5 seconds, or the like.

Step 507: The management device obtains the domain name of the network device from the network device using the used IP address by using the management protocol based on the used IP address.

The domain name file of the network device stores the domain name of the network device; therefore, the management device can use the management protocol to obtain the domain name of the network device from the domain name file of the network device, which is the first implementation below; the management device also The management protocol can be used to obtain the domain name file from the network device, and then the domain name of the network device can be obtained from the domain name file, that is, the following second implementation manner.

For the first implementation, this step can be implemented through the following steps (1) to (4), including:

(1): The management device generates a first acquisition request whose transmission protocol is the management protocol, and the first acquisition request is used to acquire the domain name of the network device.

The first acquisition request may be a Simple Network Management Protocol (English: Simple Network Management Protocol, SNMP) message.

(2): The management device sends a first acquisition request to the network device according to the IP address of the network device.

(3): The network device receives the first acquisition request sent by the management device, acquires the domain name of the network device from the domain name file of the network device according to the first acquisition request, and sends the domain name to the management device.

(4): The management device receives the domain name.

For the second implementation, this step can be implemented through the following steps (A) to (D), including:

(A): The management device generates a second acquisition request whose transmission protocol is the management protocol, and the second acquisition request is used to acquire the domain name file of the network device.

Likewise, the second acquisition request may be an SNMP message.

(B): The management device sends a second acquisition request to the network device according to the IP address of the network device.

(C): The network device receives the second acquisition request sent by the management device, acquires the domain name file of the network device according to the second acquisition request, and sends the domain name file to the management device.

(D): The management device receives the domain name file, and obtains the domain name of the network device from the domain name file.

After acquiring the domain name in the first or second manner above, the management device associates and stores the IP address and domain name of the network device, so as to facilitate subsequent management of the network device based on the domain name or IP address.

Step 509: The management device manages the network device according to the domain name.

When the management device communicates with the network device, the management device needs to obtain the IP address of the network device, and communicate with the network device based on the IP address. Correspondingly, this step can be realized by the following steps (1)-(3), including:

(1): Before the management device communicates with the network device, the management device queries the domain name server for the domain name of the network device.

Because the IP address of the network device is stored in the domain name server. Therefore, before the management device communicates with the network device, the management device sends a domain name request to the domain name server, and the domain name request carries the domain name of the network device, so as to request to resolve the IP address of the network device from the domain name server. The domain name server receives the domain name request sent by the management device, obtains the domain name of the network device carried in the domain name request, obtains the IP address of the network device from the corresponding relationship between the domain name and the IP address according to the domain name, and sends the request to the management device. The IP address of this network device.

(2): The management device receives the IP address corresponding to the domain name answered by the domain name server.

(3): The management device communicates with the network device based on the IP address.

Because the management device has determined the IP address of the network device in step 508; because only when the network device is restarted, the IP address of the network device will change. Therefore, the IP address of the network device is valid for a period of time. Therefore, the management device may also directly use the detected IP address of the network device without obtaining the IP address of the network device through the above steps (1) to (3). Correspondingly, this step can be:

Before the management device communicates with the network device, the management device obtains the IP address corresponding to the domain name from the correspondence between the domain name and the new IP address according to the domain name of the network device, and communicates with the network device based on the IP address.

After the network device is restarted, the new IP address assigned by the DHCP server to the network device in the cloud management system may be different from the IP address assigned to the network device last time. Therefore, the management device acquires the domain name of the network device based on the IP address that has been used, and manages the network device based on the domain name instead of the IP address. Since the domain name of the network device remains unchanged, the management of the network device by the management device is not affected by the change of the IP address of the network device.

The embodiments of the present disclosure provide a method for managing network devices, and the method is applied among network devices, management devices, cloud managers, and domain name servers. In the embodiments of the present disclosure, the network device restart is taken as an example for description. Referring to Figure 6, the method includes:

Step 601: The network device receives the assigned new IP address.

When the network device restarts, the network device sends a new allocation request to the DHCP server, so as to request the DHCP server to re-allocate an IP address for the network device. The network device stores the new IP address assigned to the network device by the DHCP server in non-volatile memory.

Step 602: The network device sends a new registration request including the new IP address and domain name of the network device to the cloud manager.

Since the DHCP server dynamically assigns an IP address to the network device, the IP address assigned to the network device last time and the new IP address may be different. The network device acquires the last IP address assigned by the network device from the non-volatile memory, and determines whether the IP address assigned last time and the new IP address are the same. When the IP address assigned to the network device last time is different from the new IP address, the network device sends a new registration request including the new IP address and domain name of the network device to the cloud manager. Wherein, the new registration request may further carry the MAC address of the network device, and the new registration request may also carry the IP address allocated last time of the network device.

When the IP address assigned to the network device last time is the same as the new IP address, since it has already been registered in the cloud manager, repeated registration is not performed in this step, thereby saving network resources. In addition, after the network device receives the currently assigned IP address, the IP address is stored in the non-volatile memory, so that the network device can obtain the IP address from the non-volatile memory after the network device is subsequently reassigned an IP address. the IP address, and determine whether the IP address and the reassigned IP address are the same to determine whether to register in the cloud manager.

Step 603: The cloud manager receives the new registration request including the new IP address and domain name of the network device sent by the network device, and sends the corresponding relationship between the domain name of the network device and the new IP address of the network device to the domain name server.

The cloud management device may carry the correspondence between the domain name of the network device and the new IP address of the network device in the first DNS message. The management device may also carry the correspondence between the domain name of the network device and the new IP address of the network device in the second DNS message whose message type is updated, and send the second DNS message whose message type is updated to the domain name server. The second DNS packet carries the correspondence between the domain name of the network device and the new IP address.

Before the cloud manager sends the corresponding relationship between the domain name of the network device and the new IP address of the network device to the domain name server, the cloud manager obtains the last IP address assigned to the network device, and determines the last IP address assigned to the network device Whether the address is the same as the new IP address; when the IP address assigned to the network device last time is different from the new IP address, the cloud manager sends the domain name of the network device and the new IP address of the network device to the domain name server. relation.

The cloud manager can obtain the last assigned IP address of the network device in the following three ways. For the first method, after the cloud manager assigns a domain name to the network device, the cloud manager stores the correspondence between the domain name and the IP address of the network device; correspondingly, the cloud manager obtains the IP address that was assigned to the network device last time The step of addressing may be as follows: the cloud manager obtains, according to the domain name of the network device, the IP address allocated last time of the network device from the corresponding relationship between the domain name and the IP address.

For the second method, the new registration request carries the IP address allocated last time of the network device; the cloud manager obtains the IP address allocated last time of the network device from the new registration request.

For the third manner, after the cloud manager assigns the domain name to the network device, the cloud manager stores the correspondence between the MAC address and the IP address of the network device. Correspondingly, the step for the cloud manager to obtain the IP address that was assigned to the network device last time may be: the cloud manager obtains, according to the MAC address of the network device, from the correspondence between the MAC address and the IP address, that the network device was lastly assigned. The assigned IP address.

Step 604: The domain name server receives the correspondence between the domain name of the network device and the new IP address of the network device sent by the cloud manager, and updates the correspondence between the domain name of the network device and the IP address assigned last time to the network device The corresponding relationship between the domain name and the new IP address.

The domain name server receives the second DNS message sent by the cloud manager, obtains the domain name of the network device and the new IP address of the network device from the second DNS message, and, according to the domain name of the network device, obtains the domain name of the network device and the new IP address of the network device. The IP address corresponding to the domain name in the IP address correspondence is modified to the new IP address of the network device.

When the network device restarts, the domain name server receives the correspondence between the domain name of the network device and the new IP address of the network device sent by the cloud manager, and updates the correspondence between the domain name and IP address of the network device to the domain name of the network device The new IP address of the network device is stored in the domain name server, so that when the subsequent management device communicates with the network device, the new IP address of the network device can be resolved from the domain name server.

Step 605: The management device manages the network device according to the domain name.

This step is the same as step 509 and will not be repeated here.

After the network device is restarted, the new IP address assigned by the DHCP server to the network device in the cloud management system may be different from the IP address assigned to the network device last time. Therefore, the management device acquires the domain name of the network device based on the IP address that has been used, and manages the network device based on the domain name instead of the IP address. Since the domain name of the network device remains unchanged, the management of the network device by the management device is not affected by the change of the IP address of the network device.

After the network device is restarted, the new IP address assigned by the DHCP server to the network device in the cloud management system may be different from the IP address assigned to the network device last time. Therefore, the management device acquires the domain name of the network device based on the IP address that has been used, and manages the network device based on the domain name instead of the IP address. Since the domain name of the network device remains unchanged, the management of the network device by the management device is not affected by the change of the IP address of the network device.
