Description
Technical Field
The disclosure relates to the field of communication technologies, and in particular, to a method for detecting a card in place, a network device and a storage medium.
Background
Plug interrupt: when the standby main control or service board is inserted into the slot position of the frame or pulled out from the slot position, the CPLD detects the level signal of the single board in place and converts the level signal into an interrupt signal, and the interrupt signal is reported to the main control and the standby main control, which is called as 'plug interrupt' for short.
Inter-board communication: in the distributed machine frame, the control messages are communicated interactively between the single boards, and the control messages are used for synchronizing state data among the single boards, and the like, so that the management and the notification among the main control and the single boards are facilitated.
Lan Switch chip: the two layers exchange chips.
As shown in fig. 1, in a form of a chassis of a distributed router, each chassis is equipped with two main control boards (main control and standby main control), and multiple service boards or mesh boards (providing high-speed channels of mesh for completing the forwarding of the cross boards, which are separately integrated onto a single board, called a mesh board), and each single board is inserted into a corresponding slot. The on-site or off-site state of the single board of each slot position is composed of hardware connection lines of the backboard of the machine frame, on-site signals of the service board or the screen board are simultaneously connected to two main control boards, and the on-site state of the single board is identified and represented through high level or low level of the circuit.
When the main control board is pulled out, the in-place signals of the standby main control board, the service board and the screen board are separated in the pulling-out process of the main control board, so that in-place signals of other single boards are changed (actually caused by the pulling-out of the main control board), and CPLD logic of the main control board can report the processed signals to the main control CPU for one or more single board plug-in interruption. In the process of pulling out the main control board, although power is lost (power supply signal pins are separated), the survival time from the separation of the power supply pins and the power failure to the stop of the CPU often exists for 5-10ms or even longer, in the survival time, pulling out interruption of other single boards can be processed on the main control software, a single board pulling event is reported to a service module, the service module can broadcast a single board state, service switching and the like to notify other single boards in a frame, so that the single board state of a standby main control, a service board or a network board is switched into fault state, and even restarted and reset, thereby causing serious consequences such as service interruption and the like.

At present, in the process of pulling out the main control board, because the main control board is separated from in-place signals of the standby main control board, the service board and the screen board in the process of pulling out the main control board, in-place signals of other single boards are changed (actually caused by pulling out the main control board), CPLD logic of the main control board can report the signals to one or more single boards of the CPU of the main control board for plugging and breaking after processing the signals. In the process of pulling out the main control board, although power is lost (power supply signal pins are separated), the survival time from the separation of the power supply pins and the power failure to the stop of the CPU often exists for 5-10ms or even longer, in the survival time, the software of the main control board processes the pulling-out interruption of other single boards, the service module reports the single board pulling-out event to the service module, the service module can broadcast the single board state, the service switching and the like to notify other single boards in the frame, so that the single board state of the standby main control board, the service board or the network board is switched into fault state, and even restarted and reset, thereby causing serious consequences such as service interruption and the like.
In order to solve the above technical problems, an embodiment of the present disclosure provides a method for detecting a board card in place, where the method is applied to a network device, and the network device includes a main control board and a standby main control board, as shown in fig. 2, and the method includes:
s201, when the main control board detects the plugging and unplugging interruption of a service board or a network board in network equipment, a first message is sent to the standby main control board, and the first message carries identification information for representing the service board or the network board;
s202, receiving a second message sent by a standby main control board aiming at the first message, and determining whether to perform plug interrupt processing on the service board or the network board according to the second message;
the second message is generated by the standby main control board according to the result of the in-situ detection of the service board or the network board by the identification information carried in the first message.
In step S201, when the master control board senses the interrupt of the service board or the mesh board, a queue message is written, after the task reads the message, it is determined whether the opposite end master control board (standby master control board) is in Normal state (when the user actually uses, a dual-master control environment is adopted), if the situation of the opposite end master control Normal is satisfied, a first message (for example, a unicast message) is sent to the opposite end master control in the frame, and identification information (for example, a serial number) for indicating the service board or the mesh board (the service board or the mesh board in which the interrupt of the service board is detected) is added into the first message for real-time verification.
In this embodiment, the standby main control board may perform high-quality analysis processing after receiving the first message, read the current in-place state of the service board or the network board according to the CPLD of the standby main control board, obtain a detection result, and send a second message (response message) to the main control board according to the detection result, and carry the identification information.
In step S202, after receiving the second message, the master control board obtains the detection result and the identification information in the second message, and further determines according to the plug interrupt result of the service board or the mesh board detected by the detection result in the second message, if the detection result is consistent, it is determined that the service board or the mesh board belongs to the plug interrupt, and then plug interrupt processing is executed. If the service board is inconsistent with the network board, the main control board is indicated to identify the plugging interrupt of the service board or the network board by mistake, and the plugging interrupt processing is not executed.
In this embodiment, the master control board may start the timer after sending the first message, if the timer is overtime and does not reach the second message, the second message may be discarded on the link, or the standby master control board fails, and at this time, the master control board processes the plug interrupt message based on the result of its detection.
