technical field

The present disclosure relates to the technical field of frame-type communication device maintenance, and in particular, to a method, system, device and storage medium for start-up management of a frame-type device.

Background technique

In the field of communication equipment and industrial control equipment, in order to achieve high performance and high reliability, a distributed architecture design is often adopted, that is, a main control board manages other boards of the entire device and synchronizes the relevant information of each board. A frame device generally includes a main control board, a switch board, and a service board. The main control board is connected to all other boards through the backplane to manage the boards. The backplane provides various channels for the power supply, data, management, and control planes of the single board, and ERPROM stores some frame information.

Generally, when designing the hardware of a single board, the communication channel with the ERPROM on the backboard will be designed so that the information stored on the backboard can be obtained directly. The communication channel of the board, such as IPMC, SPI or I2C and other communication methods. But in this way, the selection of the chip and the design of the circuit diagram will be more demanding, and the cost of the single board will be higher. Therefore, under the balance of advantages and disadvantages, in order to control the cost, sometimes the communication channels with the backplane and other boards are removed when designing the hardware of the board. At this time, it is necessary to obtain backplane information and other board information through other methods.

When a board is started, it is generally necessary to obtain the chassis type and chassis number from the backplane. These two are necessary information for the board to start. Other information can be synchronized from the main control after the board is started. For a single-chassis device, the chassis type can be obtained from the version request response to the main control board, and the chassis number can be fixed as the same. For frame-type devices in the stacked state, since the board itself does not know its physical location, there is no way to obtain the information that does not exist on this board without communication channels with the backplane and other boards. Two key pieces of information.

In some cases, the automatic stacking method of fixed switches is provided to dynamically assign stacked frame numbers, but it is only applicable to fixed switches, not to framed take effect. A box-type device has only one board and has a simple hardware architecture. A box-type device consists of multiple boards and backplanes, and has a more complex hardware architecture. There is also a method of managing the board by exchanging EOAM messages, which also needs to start to function after the board is started normally. There is also a method for starting a single board that does not contain an EEPROM by two file transfers and loading. Both times, the TFTP server information and file information are obtained from the DHCP server by first initiating a DHCP (Dynamic Host Configuration Protocol) request. The first request for the configuration file contains hardware configuration parameters, and the second The project file with setting function is requested for the first time, but it only solves the problem of single board startup that cannot save hardware initialization parameters and reset configuration.

FIG. 3 is an overall schematic diagram of a stacking system provided by an embodiment of the present disclosure. As shown in FIG. 3 , the entire system consists of one frame or multiple frames, and each frame consists of two main control boards and several other boards. Each frame device includes a main control board, other boards, and a backplane; the main control board at least includes: a CPU, an inter-board communication network port, a control plane switching chip (communication between management boards), and access to information stored on the backplane The channel (such as access to the backplane ERPROM); other boards include at least: CPU, inter-board communication network port. The backplane at least includes: various channels of the power supply, data, management, and control planes of the single board.

Multiple boxes are linked through cascading ports to form a stacking environment. At this time, the internal network of each box is interconnected to form the entire internal network, and network packets can be transmitted across boxes.

The main control single board includes a DHCP server, an inter-board communication network port, a switching chip (responsible for managing the communication network with other single boards) and a communication channel that can access the information stored on the backplane. According to the function, the main control is divided into the main main control of the system, the main main control of this box, and the standby main control.

There is only one system master controller in the whole system. For the frame where the board is located, it is also the master controller of the frame, including the version management server and the DHCP server. It is mainly responsible for the unified management of the running version of the entire system, and the information management and transmission of other single-board chassis in this chassis. Compared with the main master control of the system, the active master control and standby master control of this frame lack the function of version management, and are still responsible for the management and transmission of information of other single-board chassis in this frame. The standby master control, compared with the former two, is on standby. In order to quickly replace the main control of this box and enter the normal working mode when the main control of this box is abnormal, so that the normal operation of the system will not be affected.

Other single boards include a DHCP client and an inter-board communication network port (connected to the switch chip port of the main control board). After normal startup, it is mainly responsible for the normal operation of equipment business functions.

The disclosure proposes a method, system, device and storage medium for single-board start-up management of frame-type equipment, which provides a single board that cannot access backplane information and has no other hardware communication means (such as IPMC channel) between single boards. The method of single-board start-up management can also be applied to a multi-chassis stacking environment, which simplifies the multi-chassis environment construction process for equipment maintenance personnel, facilitates the direct replacement of single boards between different chassis, and reduces errors caused by human operations.

FIG. 4 is a flow chart of a method for starting and managing a single board of a frame device provided by an embodiment of the present disclosure. As shown in FIG. 4 , steps 1 to 18 are included.

Step 1. According to the type of the chassis and its own slot number, the board knows what type of board it is in the chassis, whether it is the main control board or other boards. If the chassis type cannot be obtained, it is considered to be other boards. And according to the startup mode of the single board, distinguish the main controller of the system from other master controllers.

Step 2, the main controller of the system starts locally (the software versions of all boards are stored on the local hard disk of the master controller), and reads the necessary information required for startup from the backplane, such as the type and The chassis number and slot number calculate its own unique MAC and IP in the entire internal network. Configure the ACL rule of the switch chip to redirect the DHCP packets of the ports of other boards except the main control board to the local CPU, so as to prevent the DHCP message requests sent by other boards in the subrack from being received by the main controller of other subracks. The DHCP server monitors and receives the DHCP request, and responds with the chassis type, chassis number and version management server information. Open the version management server and deliver the corresponding version file according to the received version request.

Step 3, when other main controllers start, send a DHCP broadcast request (the request content includes the board type, PCB, BOM, CPU type).

Step 4: After receiving the DHCP broadcast request, the main controller of the system composes a reply message with its own chassis type, chassis number and version management server information, and replies to other master controllers. The version management server information includes the IP address of the server (that is, the internal network IP of the main control system), FTP login user name and password.

Step 5: Other masters receive the DHCP response from the main master of the system, obtain the information of the version management server, and save it, so that they can carry the version management server when replying to the DHCP requests of other single boards after the DHCP server is turned on. information.

Step 6. Other main controllers read the necessary information required for startup from the backplane, calculate their own MAC and IP addresses according to their own frame number and slot number, and configure the ACL rules of the switching chip so that all but the main control board The DHCP packets of other board ports are redirected to the local CPU to prevent the DHCP packets sent by other boards in this subrack from being received by the master controller of other subracks.

Step 7, other masters send a version download request to the version management server of the system master master (the request includes the board type, PCB, BOM, CPU type).

In step 8, the main control system of the system organizes the list of version files according to the received version request.

In step 9, the master control of the system replies the list of version files to other master controls.

Step 10, other masters download version files and configurations from the system master master via FTP according to the received version file list, and start normal startup. After the startup is complete, start the DHCP server, monitor and receive DHCP requests, and respond with the chassis type, chassis number, and version management server information.

Step 11, when other boards are started, send a DHCP broadcast request (request content includes board type, PCB, BOM, CPU type).

In step 12, due to the configuration of the ACL rule, only the master controller of the subrack can receive the DHCP requests of other boards in the subrack. If the board that sends the DHCP request is in the chassis where the system master controller is located, the system master controller is also regarded as the master controller of this chassis and will reply the DHCP request. After receiving the DHCP broadcast request, the main controller of this subrack forms a response message with its own subrack type, subrack number and version management server information, and replies to other boards. The version management server information includes the IP address of the server (that is, the internal network IP of the main control of the system), FTP login user name and password.

Step 13: After receiving the DHCP response, other single boards obtain the subrack type, subrack number and version management server information carried in the response, and fill them in the local cache.

Step 14, other single boards calculate their own MAC and IP addresses from the chassis number obtained from the local cache and their own slot numbers, so as to ensure that the IP and MAC of each single board in the entire internal network do not conflict with each other.

Step 15, other single boards send a version download request to the version management server of the system main controller (request content includes single board type, PCB, BOM, CPU type).

In step 16, the master control of the system organizes the list of version files according to the received version request.

In step 17, the main controller of the system replies the list of version files to other boards.

In step 18, the other single boards download the version files and configurations from the main control unit of the system through FTP according to the received version file list, and start normal startup.

Among them, the main control board on each frame starts the DHCP server (it only needs to have the ability to respond to the DHCP broadcast packet), responds to the DHCP requests of other boards, and the DHCP response of each main control board on the same frame The content is the same. Reply The DHCP response to each board is extended on the standard DHCP protocol, carrying the FTP server information, as well as the subrack type, subrack number and other information required for startup. The deployment is simple, the process is simple, and all the necessary information for starting is transmitted in one response. Configure ACL rules on the ports of all boards except the main control board through the switch chip on the main control side to redirect DHCP packets to the CPU, that is, the DHCP packets of all boards except the main control board will only be transmitted to If the master controller of this subrack is connected, it means that other boards will only receive the DHCP response from the master controller of this subrack. Avoid in the stack state, after multiple frames form a large internal network, DHCP packets are transmitted across frames, and each non-master board will receive the DHCP responses from the masters of all frames. The IP and MAC of a single board are obtained in a static way, and are obtained through calculation of the physical location information of the single board (chassis number, slot number, CPU number), ensuring that the IP and MAC of each single board will not interact with each other even in the stack state. conflict.
