(Mandatory) Collecting Diagnostic Information

The display diagnostic-information command displays debugging information outputs of multiple display commands. You can use this command to collect device diagnostic information.

The display diagnostic-information [ file-name ] command displays the device diagnostic information on screen or outputs the information to a .txt file. The device diagnostic information includes startup configuration, current configurations, interface information, time, and system version. The following is an example:

<AC> display diagnostic-information dia-info.txt
  This operation will take several minutes, please wait......................... 
................................................................................ 
…… 
Info: The diagnostic information was saved to the device successfully.

By default, the diagnostic information is saved to the root directory of the default storage device (flash:/ or sdcard:/). You can run the dir command in the user view to check whether the file is correctly generated.

After a device becomes faulty, provide the device diagnostic information to agents or technical support personnel immediately for fast fault location. For the method of transmitting the diagnostic information from the device to your computer, see Transferring Files Using FTP/TFTP.

• Executing this command requires a long time. You can press Ctrl+C to pause diagnosis information display on screen.
• When a large amount of diagnostic information is displayed, the CPU usage may be high in a short period.
