Embodiment Construction

[0020] The invention provides a method for automatically associating CPU sub-boards and boards in a grouping device, using the existing resources of the forwarding boards to uniquely mark each board and automatically realize the matching between the CPU and the boards. The present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0021] figure 1 It is a structural schematic diagram of the forwarding board and the CPU sub-board in the present invention, indicating the relationship between the CPU sub-board and the forwarding board. The MAC address of the Ethernet port of the grouping device is stored on the forwarding board of the grouping device. This MAC address is uniquely assigned in the world. When each forwarding board is processed, it will provide its own MAC address and solidify it on the board. in the non-volatile memory. In this description, the assigned MAC address is used as the identification ID ...

Abstract

The invention discloses a method for automatically associating a CPU sub-board with a board in a grouping device. Card ID; Step 2: Determine whether the board ID is the same as the board ID saved on the CPU subboard, if they are the same, go to step 3; if they are different, go to step 4; Configure the forwarding board with the hardware characteristic data of the forwarding board, and end; Step 4: The CPU daughter board reacquires and stores the hardware characteristic data on the forwarding board, and then configures the forwarding board with the new characteristic data, and ends. In the present invention, the MAC address of the forwarding board is used as the unique identification ID of each forwarding board, and whether the two match is obtained according to whether the forwarding board identification ID stored on the CPU subboard is the same as the identification ID on the forwarding board Judgment results, automatic recognition and matching.

Description

technical field [0001] The invention relates to grouping equipment, in particular to a method for automatically associating CPU sub-boards and boards in the grouping equipment. Background technique [0002] A packet device usually consists of a forwarding plane and a control plane. The forwarding plane is a channel for data transmission, and usually consists of two parts: forwarding hardware boards and forwarding application software. The forwarding hardware board is composed of board CPU, forwarding series IC, clock, power supply and other logic devices. To facilitate the CPU upgrade of the board, the CPU of the forwarding board is usually connected to the board through a connector in the form of a sub-board. When the CPU sub-board fails, it is very convenient to deal with the card failure by replacing the CPU sub-board. Therefore, the use of the CPU sub-board facilitates the upgrading of the processing capability of the grouping device and saves the upgrade cost of the w...
