Embodiment

[0058] The following takes the commonly used data center white box switch SONiC operating system as an example. The SONiC operating system and BMC can be set to allow the NOS configuration file saving function to be enabled. When the function is enabled, every time SONiC saves the existing configuration into the configuration file config_db, SONiC will simultaneously copy the config_db file and transfer the file to the BMC through the data transfer bus. The BMC will also compare whether the config_db file has changed at regular intervals, and the configuration file will be automatically backed up by the BMC if the change occurs.

[0059] If BMC allows NOS configuration file backup, it will receive the configuration file transmitted by SONiC and verify it, otherwise SONiC will report an error. After the verification is completed, the BMC will determine the storage space of its own FLASH. If there is enough space, the backup file will be written into the FLASH. Otherwise, the ol...

Abstract

The invention provides a method and device for restoring a switch. The method comprises the steps that the switch judges whether BMC backup is started or not when a configuration file is backed up; inresponse to starting of BMC backup, the configuration file is stored in the switch and transmitted to the BMC at the same time; the BMC checks whether the configuration file stored in the switch is changed or not every other threshold time; in response to the change, the BMC copies the changed configuration file into the BMC; and in response to first starting after the switch reinstalls or updates the network operating system, the switch acquires the newly stored configuration file from the BMC to complete restoration of the switch. By using the method provided by the invention, the time andlabor required for recovering a service after a failure can be reduced, and the backup convenience and flexibility of the data center white-box switch and the reliability of the overall operation areimproved.

Description

technical field [0001] The field relates to the field of computers, and more particularly to a method and device for restoring a switch. Background technique [0002] The white box switch has the function of decoupling software, which can reduce costs and improve the flexibility of use. It can build different components and modules for the specific needs of manufacturers, and is welcomed by many manufacturers and data centers. The biggest highlight of the white-brand switch is its strong openness. Therefore, the white-brand switch has more choices in terms of operating systems and software. [0003] With the maturing of SONiC (Software for Open Network in the Cloud) system and more and more applications in the Internet industry, SONIC+white box switch will be the mainstream access for future data centers The development of switches offers more possibilities. Since the SONIC system itself is open source software and has a short development history, there are still various p...
