(1) and when the current state of the main dependent board is determined to be a failure state, controlling the standby dependent board to be upgraded to the target main dependent board.
(2) And forwarding the service message based on the target main dependency board and the attribute information.
When the main control board senses that the current state of the main dependency board is in a failure state, the main dependency board informs the standby dependency board that the main dependency board is changed at the moment, and all messages are switched to a new main dependency board for receiving and sending. Since the main dependent board backups the operating data or the table entry information of the optical board interface to the standby dependent board, the standby dependent board can continue to work according to the previous operating data after the main dependent board is upgraded.
Further, after the two frames of equipment form the IRF stack, when the standby dependency board is raised to the main dependency board thickness, the stack message can be directly received and sent from the target main dependency board, and the situation that the stack is directly split once the motherboard is abnormal is avoided.
The optical board is attached to the main and standby forwarding dependent boards, and after the main dependent board is abnormal, the standby dependent board is automatically upgraded to the main dependent board for continuing forwarding, so that the redundancy stability of the network equipment is improved.
In the control method for the network device provided in this embodiment, when the standby dependency board is plugged, all the attribute information of the target optical board is synchronized to the standby dependency board, so that the data of the standby dependency board and the data of the active dependency board are synchronized, and when one of the standby dependency board and the active dependency board is abnormal, the other one of the standby dependency board and the active dependency board can ensure normal forwarding of the packet. Some functions of the interface only need to operate on the dependence board, so that when the optical board is dependent on the main control board and the forwarding interface board, the work of the main control board and the communication between the boards can be reduced, and the forwarding performance of the equipment is improved.
As an optional implementation manner of this embodiment, the optical board dependent board may be simulated into a role of a standby main control board on a software level, and the standby main control board cannot be upgraded to the role of the standby main control board of the main control board, so that the machine frame form of the network device is composed of the main and standby main control boards and the optical board, and all interface configuration information and forwarding table entries exist on all main control boards.
