When you perform routine maintenance or the system fails, you might need to display the operational information of each feature module to locate failures. Typically, you need to run the display commands individually. However, you can use the display diagnostic-information command in any view to display or save the operational statistics of multiple feature modules of the device. This command displays the output of the display clock, display version, display device, and display current-configuration commands.

· Save the operational statistics for each feature module of the device:

<H3C>display diagnostic-information

Save or display diagnostic information (Y=save, N=display)? [Y/N]:y

Please input the file name(*.tar.gz)[cfa0:/diag_WX3840H_20170420-015630.tar.gz]:

Diagnostic information is outputting to cfa0:/diag_WX3840H_20170420-015630.tar.g

Please wait...

Save successfully.

To view the contents of the XXXX.tar.gz file, perform the following steps:

a. Execute the tar extract command to extract the XXXX.gz file from the XXXX.tar.gz file.

b. Execute the gunzip command to decompress the XXXX.gz file to XXXX file.

c. Execute the more command to view the XXXX file.

· Display the operational statistics for each feature module of the device. (Details not shown.)

<H3C>display diagnostic-information

Rebooting the device

To reboot the device, use one of the following methods:

· Reboot the device at the CLI. You can remotely reboot the device in either of the following ways:

¡ Reboot the device immediately by using the reboot command.

¡ Schedule a reboot to occur at a specific time or date or after a delay by using the schedule reboot command.

· Power off and power on the device. This method cuts off the power of the device forcibly, which might cause data loss. It is the least-preferred method.

Restrictions and guidelines

· Before you reboot the device, perform the following tasks:

¡ Use the save command to save the running configuration. For more information about the save command, see configuration file management commands in H3C WX3800H Series Access Controllers Fundamentals Command Reference.

¡ Use the display startup and display boot-loader commands to verify that you have specified the correct next-startup configuration files and startup software images. If the main startup software image is corrupt or does not exist, a reboot failure will occur. To avoid a reboot failure, use the boot-loader file command to specify a new startup software image. For more information about the display startup and display boot-loader commands, see software upgrade commands in H3C WX3800H Series Access Controllers Fundamentals Command Reference.

· The device will not reboot if a file is being accessed.
