In a development stage of distributed equipment, a console port on a PCB board of a console in a chassis is usually required to be connected to debug a console in the equipment, and when the chassis is in a full-plug environment, the console port is inconvenient to plug, a part of the console port needs to be pulled out first, and after the console port is plugged, the console is reinserted, and the console undergoes a restart process; once the single board has a fault and needs to be positioned through the console port, a large amount of time is wasted in a problem recurrence loop because most faults are not easy to recur; the single board may change the operation environment of the device after the restart process of pulling out and reinserting, and the difficulty of single board fault recurrence is also increased to a certain extent, thereby being not beneficial to fault location of the device. In the using process of the distributed equipment, once a single board fails, the user can only restart the failed single board to remove the fault, and cannot perform fault location by logging in a console port of the failed single board, so that hidden dangers are buried for subsequent operation of the equipment.

Fig. 3 is a block diagram of a network device 100 according to an embodiment of the present invention. The network device 100 may be a switch, a router, or other devices, the network device 100 includes a main control board 110, one or more single boards 120, and a backplane 130, where the main control board 110 and the one or more single boards 120 are all connected to the backplane 130, so as to implement a physical path between the main control board 110 and the single board 120 through the backplane 130.
The main control board 110 includes a main control board CPU112, a main control board CPLD114 and a control port 116, and the main control board CPU112, the control port 116 and one or more single boards 120 are all connected to the main control board CPLD 114.
The single board 120 includes a single board CPU122, and the main control board CPLD114 and the single board CPU122 are both connected to the backplane 130, so that the single board CPU122 is communicated with the main control board CPLD114 through the backplane 130. In practical applications, the single board CPU122 may be directly connected to the backplane 130, or may be connected to the backplane 130 through a single board CPLD disposed in the single board 120, which is not limited in this application.
In this embodiment, since the CPLD114 and the board CPU122 of each board 120 are both connected to the backplane 130, the backplane 130 can implement physical communication between the CPLD114 and the board CPU122 of each board 120.
In this embodiment, the control port 116 may be a console port, which is used to connect to an external device (e.g., a notebook computer), and after the network device 100 is connected to the external device through the control port 116, a user may configure and manage the network device 100 using the external device.
In this embodiment, the single board 120 may include a service board and a network board, where the number of the service board and the number of the network board may be set according to the actual need of the network device 100, which is not limited in this application.
Fig. 4 is a flowchart illustrating a board management method according to an embodiment of the present invention. It should be noted that, the board management method according to the embodiment of the present invention is not limited by fig. 4 and the specific sequence described below, and it should be understood that, in other embodiments, the sequence of some steps in the board management method according to the embodiment of the present invention may be interchanged according to actual needs, or some steps in the board management method may be omitted or deleted. The board management method may be applied to the main control board 110 of the network device 100 shown in fig. 3, where the main control board 110 is used to manage more than one board 120 of the network device 100, and the specific flow and steps of the board management method are described in detail below with reference to fig. 4.
In step S201, the main control board CPU receives a first control instruction sent by the external device through the control port.
In the present embodiment, the control port 116 on the main control board 110 is communicated with the main control board CPU112 through the main control board CPLD114 by default, and is not communicated with one or more single boards 120. After the user connects the control port 116 with the external device, a first control command can be input to the external device, and after the first control command is sent to the control port 116 by the external device, the first control command is transmitted to the main control board CPU112 through the main control board CPLD114 by the control port 116.
Step S202, the CPU of the main control board determines a target single board from more than one single board according to the first control instruction, and sends a target single board communicating instruction to the CPLD of the main control board.
In this embodiment, the first control instruction includes a board slot number, and after receiving the first control instruction, the main control board CPU112 determines a target board from the more than one boards 120 according to the board slot number in the first control instruction, and sends a target board connection instruction to the main control board CPLD 114.
In this embodiment, different boards 120 are connected to different slots on the backplane 130, and the board 120 on each slot has a corresponding slot number, so that the main control board CPU112 can determine the board 120 that the control port 116 needs to communicate with, i.e., the target board, according to the board slot number in the first control instruction by carrying the board slot number in the first control instruction.
Step S203, the CPLD disconnects the control port from the CPU of the main control board and connects the control port with the target board according to the target board connection instruction, so as to establish a physical channel between the control port and the target board, thereby facilitating the user to log in the target board through the control port.
In this embodiment, the main control board CPU112 includes a first transmission port, the first transmission port includes a first input pin and a first output pin, the first input pin is connected with the control port 116 through the main control board CPLD114 to form an input channel, and when the input channel is communicated, the main control board CPU112 can receive data through the control port 116; the first output pin is connected to the control port 116 through the CPLD114 of the main control board to form an output channel, and when the output channel is connected, the CPU112 of the main control board can transmit data through the control port 116.
In this embodiment, when the CPLD114 disconnects the control port 116 from the CPU112 of the main control board according to the target board connection command, the CPLD 116 disconnects the control port 116 from the first output pin according to the target board connection command, and keeps the control port 116 connected to the first input pin. That is, the main control board CPLD114 only disconnects the output channel between the control port 116 and the first output pin, and the input channel between the control port 116 and the first input pin is kept connected.
In this embodiment, the single board CPU122 includes a second transmission port, where the second transmission port includes a second input pin and a second output pin, the second input pin is connected with the control port 116 through the backplane 130 and the main control board CPLD114 to form an input channel, and when the input channel is communicated, the single board CPU122 may receive data through the control port 116; the second output pin is connected to the control port 116 through the backplane 130 and the main control board CPLD114 to form an output channel, and when the output channel is communicated, the single board CPU122 may send data through the control port 116.
It can be understood that, when the main control board CPLD114 communicates the control port 116 with the target board according to the target board communication instruction, the control port 116 is communicated with both the second input pin and the second output pin of the second transmission port of the target board, and at this time, the output channel between the control port 116 and the second output pin and the input channel between the control port 116 and the second input pin are both in a communicated state, that is, a physical channel between the control port and the target board is established, so that a user can conveniently log in the target board through the control port. In this embodiment, when a user logs in a target board through the control port 116, the control port 116 also needs to be connected to a terminal device, so as to implement operations such as configuration, management, fault location, online fault removal, and the like on the target board, where the terminal device used for logging in the target board and the external device may be the same device or different devices, which is not limited in this application. Next, an example is given to further explain step S201 to step S203.
Referring to fig. 5, in the main control board 110, a first transmission port of the main control board CPU112 may adopt a Universal Asynchronous Receiver Transmitter (UART), which includes a first input pin RXD and a first output pin TXD, where the first input pin RXD and the first output pin TXD are both connected to the main control board CPLD114, the control port 116 also includes an input pin RX and an output pin TX, both the input pin RX and the output pin TX are connected to the main control board CPLD114, the first input pin RXD is connected to the output pin TX of the control port 116 through the main control board CPLD114 to form an input channel, and the first output pin RXD is connected to the input pin RX of the control port 116 through the main control board CPLD114 to form an output channel. The control port 116 may be default to be connected to both the first input pin RXD and the first output pin TXD of the first transmission port, and to be disconnected to both the second input pin and the second output pin of the second transmission port of all the boards 120.
Taking the network device 100 shown in fig. 6 as an example, the above-mentioned one or more boards 120 include 2 service boards (service board E)1And service board E2) And 2 net plates (net plate S)1And a net plate S2) Service board E1Service board E2Screen plate S1And a screen plate S2Respective CPUs are connected to the backplane 130 via 1-way connection, assuming that the service board E1And service board E2The corresponding slot numbers are respectively '1' and '2', and the screen plate S1And a net plate S2The corresponding slot numbers are respectively '3' and '4'; the CPLD114 of the main control board needs to be connected to the backplane 130 through 4 lines, so as to be connected to the service board E through the 4 lines respectively1Service board E2Screen plate S1And a screen plate S2And (4) communicating. It should be noted that the above-mentioned "1-way connection line" does not indicate 1 connection line, and in this embodiment, the "1-way connection line" at least includes a connection line for connecting the CPLD114 of the main control board and the service board E1Service board E2Screen plate S1Or net sheet S 22 connecting lines between which input channels and output channels are formed; in fact, in practical applications, the "1-way connection" may include more connection lines.
Assume that in the network device 100 shown in fig. 6, the input channel (TX) -between the control port 116 and the main control board CPU112 is controlled>RXD) and output channel (RX) -between the control port 116 and the main control board CPU112>TXD), control port 116 and service board E1Business, industryService board E2Screen plate S1And a screen plate S2They are not connected, as shown in fig. 7, the solid line indicates connection, and the dotted line indicates disconnection. It is now necessary to switch the control port 116 to the traffic panel E1Service board E2Screen plate S1Or net sheet S2If one of the slot numbers is communicated, after the user can connect the control port 116 with the external device, the user inputs a first control instruction on the external device, where the first control instruction may be "comlpu slot-id," where "slot-id" is a slot number of the board, and is used to indicate that the control port 116 needs to be switched to the board 120 with the slot number of "slot-id.
For example, a user inputs a first control instruction "com lpu slot-1" on an external device through a command line, where the slot-1 "indicates that the slot number of a board is" 1 ", and after the main control board CPU112 receives the first control instruction through the control port 116 and obtains the slot number" slot-1 "of the board according to the first control instruction, the service board E with the slot number" 1 "can be determined1Is the target veneer, and sends the target veneer connection instruction to the main control board CPLD 114.
The sending of the target board connection instruction to the main control board CPLD114 by the main control board CPU112 may be realized by writing a register in the main control board CPLD 114. For example, when the main control board CPU112 determines the service board E1When the target board is the target board, the CPU112 of the main control board may write "001" (i.e., target board connection instruction) to the register in the CPLD114 of the main control board; when the main control board CPU112 determines the service board E2When the target single board is used, writing '010' (namely a target single board communication instruction) into a register in the main control board CPLD 114; when the target board connection command is "001", the CPLD114 disconnects the input pin RX of the control port 116 from the first output pin TXD according to the target board connection command, and keeps the output pin TX of the control port 116 connected to the first input pin RXD, so that the input pin RX and the output pin TX of the control port 116 are both connected to the service board E1Communicate to establish control port 116 with service board E1The physical path therebetween.
As shown in fig. 8, at service board E1Second on its CPUThe transmission port may also be a Universal Asynchronous Receiver Transmitter (UART), which includes a second input pin RX1 and a second output pin TX1, where the second input pin RX1 and the second output pin TX1 are both connected to the backplane 130, and when the CPLD114 of the main control board CPLD114 connects the control port 116 and the service board E1When the communication is performed, the input channel between the output pin TX of the control port 116 and the second input pin RX1 and the output channel between the input pin RX of the control port 116 and the second output pin TX1 are both communicated, so that the control port 116 is directly connected to the service board E1At this time, the user can directly log in the service board E through the control port 1161。
As shown in fig. 9, after the CPLD114 of the main control board operates successfully according to the target board connection instruction, the input channel (TX) -between the control port 116 and the CPU112 of the main control board is controlled>RXD) remains connected, controls the output channel (RX) -between the port 116 and the main control board CPU112>TXD) is disconnected, controlling port 116 and service board E1Input channel (TX) -between>RX1) and an output channel (RX-)>TX1) are all connected.
It should be noted that, in this embodiment, the service board E2Screen plate S1And a screen plate S2The structure of other boards 120 and the principle of communicating with the control port 116 can be referred to the service board E shown in fig. 81And will not be described herein.
As can be seen, when the main control board CPLD114 switches the control port 116 from being communicated with the main control board CPU112 to being communicated with the target board according to the target board communication instruction, only the output channel between the main control board CPU112 and the control port 116 is disconnected, and the input channel between the main control board CPU112 and the control port 116 remains connected, so that the main control board CPU112 can obtain the second control instruction input by the user through the control port 116; after the control port 116 is communicated with the target board, the user may use an external device to connect with the control port 116, and directly log in the target board through the control port 116, to perform operations such as configuration, fault location, online fault removal, and the like on the target board, thereby greatly improving the fault location efficiency of the network device 100 in the research and development stage and the use stage.
Further, as shown in fig. 10, in this embodiment, after the main control board CPU112 operates the main control board CPLD114 to communicate the control port 116 with the target board, the main control board CPLD114 may be operated to switch back the control port 116 to communicate with the main control board CPU112, so that the user may log in the main control board 110 again through the control port 116, specifically refer to the following steps S204 to S206.
Step S204, the main control board CPU receives a second control instruction sent by the external device through the control port.
Similar to the first control command, the second control command may be input by the user on an external device connected to the control port 116, and transmitted to the main control board CPU112 by the control port 116 after being received by the control port 116. Since the input channel between the control port 116 and the first input pin of the main control board CPU112 is not disconnected when the main control board CPLD114 connects the control port 116 with the target board, the main control board CPU112 may obtain the second control instruction through the input channel between the first input pin and the control port 116.
And step S205, the CPU of the main control board sends a target single board disconnection instruction to the CPLD of the main control board according to the second control instruction.
Step S206, the main control board CPLD connects the control port with the first output pin according to the target board disconnection instruction, and disconnects the control port from the target board.
In this embodiment, the main control board CPU112 receives a second control instruction through an input channel between the first input pin of the main control board CPU112 and the control port 116, and sends a target board disconnection instruction to the main control board CPLD114 according to the second control instruction; since the input channel between the control port 116 and the first input pin of the main control board CPU112 is always kept connected, the main control board CPLD114 only needs to disconnect the control port 116 from the target board according to the target board disconnection instruction, and connect the first output pin of the main control board CPU112 with the control port 116, so that the user can log in the main control board 110 again through the control port 116.
It can be understood that, when the main control board CPLD114 disconnects the control port 116 from the target board according to the target board disconnection instruction, both the second input pin and the second output pin of the second transmission port of the control port 116 and the target board are disconnected, and at this time, both the output channel between the control port 116 and the second output pin and the input channel between the control port 116 and the second input pin are disconnected.
Next, still taking the network device 100 shown in fig. 6 as an example, the steps S204 to S206 will be further described.
Assume that in the current network device 100, the control port 116 and the service board E1The input channel and the output channel are communicated with the main control board CPU112 and the service board E2Screen plate S1And a screen plate S2Is not connected. It is now necessary to switch the control port 116 back into communication with the main control board CPU112 and with the service board E1If the connection is broken, the user needs to connect the control port 116 with an external device and input a second control command on the external device, for example, the second control command may be "commpu".
When receiving the second control instruction "commpu", the main control board CPU112 sends a target board disconnection instruction to the main control board CPLD114, where sending the target board disconnection instruction to the main control board CPLD114 by the main control board CPU112 is implemented by writing a register in the main control board CPLD114, for example, writing the target board disconnection instruction "000" into the register in the main control board CPLD 114.
Since the output pin TX of the control port 116 and the first input pin RXD of the first transmission port of the main control board CPU112 are always in a connected state, after the main control board CPU112 writes the target single board disconnection instruction "000" into the register in the main control board CPLD114, the main control board CPLD114 only needs to connect the input pin RX of the control port 116 and the first output pin TXD of the first transmission port of the main control board CPU112 according to the target single board disconnection instruction "000", and at this time, both the input channel and the output channel between the control port 116 and the main control board CPU112 are connected; in this embodiment, the CPLD114 of the main control board further needs to connect the input pin RX of the control port 116 and the service board E according to the target board disconnection command "0001Is disconnected from the second output pin TX1 of the second transmission portConnect, and connect the output pin TX of the control port 116 with the service board E1The second input pin RX1 of the second transmission port, thereby disconnecting the control port 116 from the service board E1The input channel and the output channel are not communicated; at this time, the user can log in the main control board 110 again through the control port 116, so as to perform operations such as configuration, fault location, etc. on the main control board 110.
To sum up, the board management method and the network device provided in the embodiments of the present invention include: the method comprises the steps that a main control board CPU receives a first control instruction sent by external equipment through a control port, a target single board is determined from more than one single board according to the first control instruction, and a target single board communication instruction is sent to a main control board CPLD, the main control board CPLD disconnects the control port from the main control board CPU and communicates the control port with the target single board according to the target single board communication instruction, so that a physical channel between the control port and the target single board is established, and a user can conveniently log in the target single board through the control port. In this embodiment, when the control port is disconnected from the main control board CPU, the control port is only disconnected from the first output pin of the first transmission port on the main control board CPU, and is connected to the first input pin of the first transmission port on the main control board CPU; when the control port needs to be switched back to be communicated with the main control board, the main control board CPU sends a target single board disconnection instruction to the main control board CPLD according to a second control instruction sent by the external equipment, and the main control board CPLD communicates the control port with the first output pin according to the target single board disconnection instruction and disconnects the control port from the target single board. It can be seen that, the master control board CPU controls the master control board CPLD, thereby realizing the switching of connectivity between the control port and the master control board CPU and the single board, so that the control port can be directly connected to the master control board and also directly connected to the single board, thereby solving the problem that the service board and the web board cannot be directly logged in through the console port in the prior art, and the network device can perform fault location in case of a fault of the single board in the research and development stage or in the user use stage, without recurring problems, without wasting a large amount of time in the problem recurring link, thereby improving the fault location efficiency, and also improving the customer experience and the product competitiveness to a certain extent.
