Description
Technical Field
The invention relates to the technical field of switches, in particular to a method, a system, a terminal and a storage medium for synchronizing factory information of a switch.
Background
The DMI is a management system for helping to collect information of a computer system, and is mainly used for storing related data of the system and peripheral equipment, wherein the data comprises system configuration information such as a CPU, a memory, an I/O expansion slot and the like. The SMBIOS is a unified specification that a motherboard or system manufacturer needs to follow to display product management information in a standard format. The collection of DMI information must be performed under the condition of strictly following the SMBIOS specification, and the collected data is stored in the SMBIOS table. The DMI plays the role of an interface between a management tool and an operating system, and establishes a standard manageable system, thereby facilitating the management and viewing of relevant information of the system by computer manufacturers and users. FRU is an important facility for recording device configuration information, and devices of a typical size may have their own FRU, such as power supply, fan, BMC, etc. The ONIE is a small operating system for bare metal switches, and mainly provides an automatic configuration environment for installing images of operating systems provided by vendors. The ONIE has an own FRU which is stored in EEPROM equipment of the ONIE, and stores important product information provided by manufacturers, so that the FRU is not easy to lose after power failure. Through the FRU of the ONIE, vendors and users can view asset information, MAC address, serial number, manufacturer, etc. of the switch device. Usually, when the switch equipment leaves the factory, the information of the corresponding fields of the DMI and the FRU should be kept consistent, i.e. synchronous update of the information of the DMI and the FRU is required. If the two information updates are not synchronous, when the related field information of the FRU is changed, and a certain device is replaced or updated, the phenomenon that the system configuration information of the DMI and the FRU is inconsistent occurs, so that the BIOS code needs to be modified again, a new version is issued, and the research and development investment is increased.
The existing information synchronization methods are two, namely: updating information in the DMI through static character strings set in BIOS source codes, wherein the method enables the BIOS to use the static character strings written in advance to construct a DMI table in a starting stage, and when a certain accessory in the switch is replaced or updated, synchronous updating of the DMI information is required to be ensured through updating the static character strings in the codes; in general, a solution of synchronizing BMC FRUs by using DMI is adopted in a server, and IPMI commands are sent to the BMC to obtain FRU information, so as to construct a DMI table. The scheme can ensure synchronous update between DMI and BMC FRU information.
However, updating the DMI information through the static string is cumbersome and complex, and once the information of the related devices of the switch product is changed, the BIOS source code needs to be modified, and the version needs to be reissued, which not only wastes time and labor, but also delays the development and progress of the product. By adopting the scheme of the DMI synchronous BMC FRU, the synchronous update between the DMI and BMC FRU information can be ensured, but the switch equipment is not necessarily provided with BMC, so the scheme needs to be changed according to the research and development requirements of the actual switch.

The I2C bus is a simple, bi-directional two-wire synchronous serial bus developed by Philips corporation. It requires only two wires to transfer information between devices connected to the bus. The master device is used to initiate the bus transfer of data and generate a clock to open the transfer device, where any addressed device is considered a slave device. If the host computer is to send data to the slave device, the host computer firstly addresses the slave device, then actively sends the data to the slave device, and finally the host computer terminates the data transmission; if the host is to receive data from the slave, the slave is addressed by the master first, then the host receives data sent by the slave, and finally the host terminates the receiving process. In this case, the host is responsible for generating the timing clock and terminating the data transfer.
