After the refresh is completed, judge whether the firmware of the first switch is successfully refreshed by confirming the FW version information and running status of the first switch. If the FW version information and the running status are normal, it can be considered that the firmware refresh is successful. If the FW version information is abnormal and the configuration file is abnormal, it can be considered that the firmware refresh fails.

[0038] In some embodiments, it further includes: Simulate multiple scenarios of firmware refresh failure, and detect whether the first switch and the second switch can successfully perform firmware restoration in each scenario.

[0039] To verify the effectiveness of firmware refresh and address various problems during operation and maintenance, various scenarios of firmware refresh failure or firmware anomaly during operation and maintenance are preset, such as hardware failure, firmware file corruption, configuration error, etc. Verifying whether the Switch chip can successfully perform the restoration operation can ensure that the Switch chip can quickly and stably recover to the normal working state and avoid affecting the business.

[0040] For example, simulate multiple scenarios of failure in refreshing the firmware of the first switch, and verify whether the second switch can successfully perform a restoration operation on the first switch.

[0042] Under the OS (Operating System), use a tool to refresh the firmware of Switch Chip 1. After the refresh is completed, check the firmware version information and operating status of Switch Chip 1. If the firmware version information and operating status are normal, output that the refresh is successful and retain the new firmware image file F1_B and the relevant configuration file S1_B. If the firmware version information is abnormal and the configuration file is abnormal, output that the refresh fails and start the restoration operation: 1.

After the restoration is completed, if the firmware version information and operating status are abnormal, output that the refresh fails and start the restoration operation to perform firmware restoration again. After the restoration is completed, if the firmware version information and operating status are normal, output that the refresh is successful, and retain indicators such as the automatic recovery time, success rate, and data integrity for monitoring and evaluation.

If the firmware version information and operating status are normal, output that the refresh is successful and retain the new firmware image file F2_B and the relevant configuration file S2_B. If the firmware version information is abnormal and the configuration file is abnormal, output that the refresh fails and start the restoration operation.

[0044] Simulate the scenarios where the analog chip refresh fails, such as network failures, FW file corruption, configuration errors, high-temperature damage, etc., and verify whether Switch chip 2 can successfully perform the restoration operation to ensure that all Switch chips can quickly and stably return to the normal working state.
