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 buckle board and a board card in a grouping device. The method comprises the following steps that step 1, when the CPU buckle board is installed on the forwarding board card, board card ID of a nonvolatile memory on the forwarding board card is read; step 2, whether the board card ID is identical to board card ID stored in the CPU buckle board or not is judged, if yes, the step 3 is conducted; if not, the step 4 is conducted; step 3, the forwarding board card is configured on the CPU buckle board through hardware characteristic data, stored in the CPU buckle board, of the forwarding board card and then operation is ended; step 4, hardware characteristic data of the forwarding board card are obtained again through the CPU buckle board and stored, the new hardware characteristic data are used for configuration of the forwarding board card, and operation is ended. According to the method for automatically associating the CPU buckle board and the board card in the grouping device, an MAC address of each forwarding board card serves as the only ID of the forwarding board card, whether the forwarding board card ID stored in the CPU buckle board is identical to the board card ID of the forwarding board card or not is judged, so that a judgment result indicating whether the board card ID stored in the CPU buckle board and the board card ID of the forwarding board card are matched or not is obtained, and therefore automatic identification and matching are achieved.

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...
