[0045] In order to make the objectives, technical solutions and advantages of the present application clearer, the present application will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application, but not to limit the present application.
[0046] In an exemplary embodiment, please refer to Figure 1 , the present application provides an information configuration method, which is applied to a first network device in a data center. The data center further includes a second network device. The first network device and the second network device are respectively configured with a Link Layer Discovery Protocol (LLDP), and the first network device and the second network device are connected to each other. The method includes steps S101 to S102.
[0047] S101: Receive an information configuration instruction for the second network device sent by the user terminal.
[0048] In an example, please refer to Figure 2 , Figure 2Schematic diagram of a data center in an example. As can be seen from the figure, there are many network devices in the data center. These network devices can include devices such as repeaters, bridges, routers, gateways, firewalls, switches, etc. These network devices can be connected through physical interfaces. For example, the data center includes network device A, network device B, network device C, network device D, and network device E. Among them, network device A is respectively connected to network device C, network device D, and network device E, and network device B is also respectively connected to network device C, network device D, and network device E. The administrator can log in to and access these network devices through the account passwords and out-of-band management addresses of each network device. In the data center provided in this application, these network devices all adopt LLDP (Link Layer Discovery Protocol), so the LLDP neighbor information of network device B, network device C, network device D, and network device E can be seen on network device A and network device B, and the LLDP neighbor information of network device A and network device B can also be seen on network device B, network device C, network device D, and network device E.
[0049] When the account password of a certain network device in the data center is accidentally deleted, the administrator can connect through other network devices that are connected to the network device with the accidentally deleted account password and whose account passwords have not been accidentally deleted, and reconfigure the account password of the network device with the accidentally deleted account password. Among them, the network device with the accidentally deleted account password is the second network device, and the network device that is connected to the second network device and whose account password has not been accidentally deleted is the first network device. Exemplarily, if only the account password of network device C in the data center is accidentally deleted and the account passwords of other network devices have not been accidentally deleted, then network device C is the second network device, and network device A and network device B can be the first network devices.
[0050] In the application, when the administrator discovers that the account password of the second network device has been accidentally deleted, the administrator can no longer access the second network device through the previous account password of the first network device. However, since the physical connection between the first network device and the second network device is normal and the account password of the first network device has not been accidentally deleted, the administrator can send an information configuration instruction for the second network device to the first network device. The information configuration instruction includes the new account information and new password information that the administrator wants to configure for the second network device.
[0051] S102: Generate a Link Layer Discovery Protocol packet according to the information configuration instruction, where the Link Layer Discovery Protocol packet includes the account information of the second network device and the password information of the second network device.
[0052] After receiving the information configuration instruction, the first network device can generate a Link Layer Discovery Protocol (LLDP) packet based on the new account information and new password information that the administrator wants to configure for the second network device included in the information configuration instruction.
[0053] S103: Send the Link Layer Discovery Protocol packet to the second network device to instruct the second network device to configure the account information and password information; the account information and password information are used for the client to log in to the second network device.
[0054] Since all network devices in the data center use the LLDP protocol, the first network device can send the Link Layer Discovery Protocol packet to the second network device. After receiving the Link Layer Discovery Protocol packet, the second network device can parse the Link Layer Discovery Protocol packet to obtain the carried account information and password information, and set the received account information and password information as the account password of this network device and save the configuration. In this way, the administrator does not need to go to the location of the second network device to configure the account password in the way of directly connecting with a serial cable or adding a serial server. By remotely controlling the first network device to send the Link Layer Discovery Protocol packet to the second network device, the configuration of the account password of the second network device is completed. This not only saves labor costs but also improves the efficiency of configuring the account password.
[0055] The above information configuration method is applied to the data center. When the account password of the second network device in the data center is accidentally deleted, the administrator can remotely send an information configuration instruction for the second network device to the first network device through a computer. Then, the first network device generates a Link Layer Discovery Protocol packet including the account information of the second network device and the password information of the second network device according to the information configuration instruction. After that, the first network device sends the Link Layer Discovery Protocol packet to the second network device through the physical interface connected to the second network device. After receiving the Link Layer Discovery Protocol packet, the second network device can configure the account information and password information. Thus, the administrator can log in to, manage, and maintain the second network device through the newly configured account and password. The information configuration method of this application can remotely configure the account password of the network device and improve the efficiency of configuring the account password.
[0056] In an exemplary embodiment, please refer to Figure 3 , step S102, generating a Link Layer Discovery Protocol packet according to the information configuration instruction includes step S301 and step S302.
[0057] S301: Configure the Link Layer Discovery Protocol data unit in the Type-Length-Value format according to the information configuration instruction. The Link Layer Discovery Protocol data unit includes the account information of the second network device and the password information of the second network device.
[0058] It can be understood that the data frame for sending and receiving information in the LLDP protocol includes the destination MAC address DA of the LLDP data frame, the source MAC address SA of the LLDP data frame, the Ethertype of the LLDP data frame, the LLDP data unit LLDPDU, and the frame check sequence FCS of the data frame. Among them, the LLDPPDU is the payload of the LLDP, which is used to carry the message to be sent. The data unit LLDPPDU adopts the TLV format, that is, the type + length + value format. The type represents the type of the TLV, the length is the length of the TLV in bytes, and the value is the value of the TLV. In the data unit LLDPPDU, the Chassis ID TLV, PortID TLV, Time To Live TLV, and End Of LLDPDU TLV are mandatory and are the parts that the data unit LLDPPDU must contain. In addition, the data unit LLDPPDU can also contain other optional TLVs. Each TLV in the data unit LLDPPDU represents an information. Currently, the TLVs with types 0 to 8 in the LLDP protocol have been used, and the TLVs with types 9 to 126 are reserved TLVs and can be customized by users. Therefore, in this application, two reserved TLVs can be selected to respectively carry the new account information and new password information that the administrator wants to configure for the second network device. After writing the account information and password information into the two selected reserved TLVs respectively, they can be configured together with the Chassis ID TLV, PortID TLV, Time To Live TLV, and End Of LLDPDU TLV to generate the link layer discovery protocol data unit.
[0059] S302: Generate a link layer discovery protocol message according to the link layer discovery protocol data unit.
[0060] Furthermore, the link layer discovery protocol data unit can be encapsulated together with the destination MAC address DA of the LLDP data frame, the source MAC address SA of the LLDP data frame, the Ethertype of the LLDP data frame, the LLDP data unit LLDPDU, and the frame check sequence FCS of the data frame to generate the link layer discovery protocol message. Among them, the destination MAC address is the MAC address of the second network device, and the source MAC address is the MAC address of the first network device. Figure 2In the data center shown, only the account password of network device C was accidentally deleted, and the account passwords of other network devices were not accidentally deleted. If the administrator chooses to configure the account password for network device C through network device A, network device C is the second network device, network device A is the first network device, the destination MAC address is the MAC address of network device C, and the source MAC address is the MAC address of network device A.
[0061] In an exemplary embodiment, refer to Figure 4 , step S301, configure the Link Layer Discovery Protocol Data Unit in Type-Length-Value format according to the information configuration instruction, including step S401 and step S403.
[0062] S401: According to the information configuration instruction, encapsulate the account information in the first preset type in the Type-Length-Value format to generate an account information unit.
[0063] In the application, it can be predefined which type of TLV in the received LLDP protocol packet configures the information carried by which network device as the account of this network device, and which type of TLV configures the information carried by which network device as the password of this network device. Subsequently, in the process of generating the Link Layer Discovery Protocol packet by the first network device, the account information and password information can be encapsulated into the corresponding TLVs respectively, so that the second network device can correctly configure the account and password.
[0064] S402: According to the information configuration instruction, encapsulate the password information in the second preset type in the Type-Length-Value format to generate a password information unit.
[0065] In one example, the TLVs of type 11 and type 12 in the reserved type can be used to implement the information advertisement of the account and password respectively. Refer to Table 1. Table 1 is the format of the account information unit and password information unit generated by encapsulating the account information with the TLV of type 11 and the password information with the TLV of type 12 in one example.
[0066] Table 1 Account Information Unit and Password Information Unit
[0067] Type Length Value 11 5 admin 12 11 password123
[0068] Among them, Type represents the type of TLV, Length represents the length of TLV, and Value represents the information carried by TLV. In this example, the type of the account information unit is 11, the length is 5, and it carries the account information "admin" that the administrator wants to configure for the second network device. The type of the password information unit is 12, the length is 11, and it carries the password information "password123" that the administrator wants to configure for the second network device.
[0069] S403: Encapsulate the account information unit and the password information unit to generate a Link Layer Discovery Protocol data unit.
[0070] After that, encapsulate the account information unit and the password information unit together with Chassis ID TLV, Port ID TLV, TimeTo Live TLV, and End Of LLDPDU TLV, etc., to generate a Link Layer Discovery Protocol data unit.
[0071] In an exemplary embodiment, the first network device is configured with a first physical interface, the second network device is configured with a second physical interface, and the first physical interface is connected to the second physical interface; please refer to Figure 5 , step S103, send a Link Layer Discovery Protocol message to the second network device, including step S501 and step S502.
[0072] S501: Enable the type-length-value function based on the Link Layer Discovery Protocol for the first physical interface according to the information configuration instruction.
[0073] S502: Send a Link Layer Discovery Protocol message through the first physical interface to the second physical interface; the second physical interface is configured with the type-length-value function based on the Link Layer Discovery Protocol.
[0074] In this application, both the first network device and the second network device support the LLDP protocol. Therefore, the type-length-value function based on the Link Layer Discovery Protocol can be enabled on the first physical interface where the first network device is connected to the second network device, so that the first network device can send a Link Layer Discovery Protocol message to the second network device through the first physical interface and the second physical interface that is pre-configured with the type-length-value function based on the Link Layer Discovery Protocol.
[0075] In an exemplary embodiment, this application provides an information configuration method, which is applied to the second network device in a data center. The data center further includes a first network device. Both the first network device and the second network device support the Link Layer Discovery Protocol, and the first network device and the second network device are connected to each other; please refer to Figure 6 , this method includes: step S601 and step S602.
[0076] S601: Receive the Link Layer Discovery Protocol message sent by the first network device.
[0077] Since all network devices in the data center use the LLDP protocol, the first network device can send Link Layer Discovery Protocol (LLDP) packets to the second network device, and the second network device can successfully receive and parse the LLDP packets sent by the first network device. The LLDP packets include the account information and password information of the second network device.
[0078] S602: Configure the account information and password information according to the LLDP packets. The account information and password information are used for the client to log in to the second network device.
[0079] After receiving the LLDP packets, the second network device can parse the LLDP packets to obtain the carried account information and password information, set the received account information and password information as the account password of this network device, and save the configuration. In this way, the administrator does not need to go to the location of the second network device to configure the account password by directly connecting with a serial cable or adding a serial server. By remotely controlling the first network device to send LLDP packets to the second network device, the configuration of the account password of the second network device is completed, which not only saves labor costs but also improves the efficiency of configuring the account password.
[0080] In an exemplary embodiment, please refer to Figure 7 , step S602, configuring the account information and password information according to the LLDP packets, including steps S701 to S704.
[0081] S701: Parse the LLDP packets to obtain the Link Layer Discovery Protocol Data Unit (LLDPDU).
[0082] After receiving the LLDP packets, the second network device first parses the LLDP packets to obtain the LLDPDU that carries the information.
[0083] S702: Read the account information stored in the Type-Length-Value (TLV) format of the first preset type in the LLDPDU.
[0084] After obtaining the Link Layer Discovery Protocol data unit, since the second network device has been pre-set to configure the information in a TLV of a certain type received as the account information of this network device, the second network device can directly read the account information stored in the type-length-value format of the first preset type in the Link Layer Discovery Protocol data unit and configure it as the account of this network device. Exemplarily, the first network device encapsulates the account information "admin" using a TLV of type 11. Therefore, after the second network device obtains the Link Layer Discovery Protocol data unit, it can directly configure the account information "admin" encapsulated in the TLV of type 11 as the account of this network device.
[0085] S703: Read the password information stored in the type-length-value format of the second preset type in the Link Layer Discovery Protocol data unit.
[0086] After obtaining the Link Layer Discovery Protocol data unit, since the second network device has been pre-set to configure the information in a TLV of a certain type received as the account information of this network device, the second network device can directly read the account information stored in the type-length-value format of the second preset type in the Link Layer Discovery Protocol data unit and configure it as the account of this network device. Exemplarily, the first network device encapsulates the password information "password123" using a TLV of type 12. Therefore, after the second network device obtains the Link Layer Discovery Protocol data unit, it can directly configure the account information "password123" encapsulated in the TLV of type 12 as the password of this network device.
[0087] S704: Configure the account information and password information.
[0088] After obtaining the account information and password information, the second network device can mark the obtained account information and password information as the account and password of this network device. Furthermore, the administrator can remotely log in to, manage, and maintain the second network device using this account and password.
