Usage Guidelines

Usage Scenario

When a fault occurs in the system, you can use the display diagnostic-information command to collect diagnostic information for fault location.

The display diagnostic-information command output includes the output for multiple display commands. Running the display diagnostic-information command is like running these display commands in batches.

If the saved-file parameter is not specified, diagnostic information is only displayed on the screen. If the saved-file parameter is specified, diagnostic information is only stored into a specified file but not displayed on the screen.

If the saved-file parameter is specified but file-name is not, the system automatically stores diagnostic information into the diagnostic-information.txt file.

If you do not specify the parameters ap, and sta, the command displays diagnostic information about all devices. If you specify a parameter (ap, or sta), the command displays diagnostic information about the specified parameter.

Precautions

  • If this command displays a long output, press Ctrl+C to abort this command.

  • This command displays diagnostic information, which helps locate faults but may affect system performance. For example, CPU usage may become high. Therefore, do not use this command when the system is running properly.

  • Running the display diagnostic-information command simultaneously on multiple terminals connected to the device is prohibited. This is because CPU usage of the device may obviously increase and the device performance may be degraded.

  • When you run this command, the device obtains or uses some personal data of users, such as the STA MAC address. Delete the personal data immediately after the command is executed to ensure user data security.

  • The command output does not support split-screen display.
