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_WX3010H-X_20170223-071047.tar.gz]:

Diagnostic information is outputting to cfa0:/diag_WX3010H-X_20170223-071047.tar.gz.

Please wait...

Save successfully.

To view the contents of the default.diag file, execute the more default.diag command in user view, and then press the Page Up and Page Down keys.

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

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 file system management commands in H3C WX2560H Access Controller Fundamentals Command Reference.

¡ Use the display startup and display boot-loader commands to make sure 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 file system management commands and software upgrade commands in H3C WX2560H Access Controller Fundamentals Command Reference, respectively.

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