Procedure

  1. Collecting Fault Information
    1. Collect operation results of the preceding steps and record the results in a file.
    2. Collect all diagnostic information and export the information to a file.

      1. Run the display diagnostic-information file-name command in the user view to collect diagnostic information and save the information to a file.
        <HUAWEI> display diagnostic-information dia-info.txt
        Now saving the diagnostic information to the device
         100%
        Info: The diagnostic information was saved to the device successfully.
      2. When the diagnostic file is generated, you can export the file from the device using FTP, SFTP, or SCP. For details, see Local File Management.
      NOTICE:
      • You can run the dir command in the user view to check whether the file is generated.
      • You can also run the display diagnostic-information command and save terminal logs in a diagnostic file on a disk. For details, see Diagnostic File Obtaining Guide.
      • 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.

    3. Collect the log and trap information on the device and export the information to files.

      1. Run the save logfile all command in the user view to save the logs in the user log buffer area and diagnostic log buffer area to the user log file and diagnostic log file, respectively.
        <HUAWEI> save logfile all
        Info: Save logfile successfully.
        Info: Save diagnostic logfile successfully.
      2. When the diagnostic file is generated, you can export the file from the device using FTP, SFTP, or SCP. For details, see Local File Management.
      NOTE:
      You can also run the display logbuffer and display trapbuffer commands to view the log and trap information on the device, and save the information in diagnostic files on a disk. For details, see Diagnostic File Obtaining Guide.
