Displaying operational statistics for the device

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 execute 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 from 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)[flash:/diag_WX1804H_20170101-142944.tar.gz]

:

Diagnostic information is outputting to flash:/diag_WX1804H_20170101-142944.tar.

gz.

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.)

Configuring the exception handling method

You can configure the device to handle system exceptions by using one of the following methods:

·          reboot—The device automatically reboots to recover from the error condition.

·          maintain—The device stays in the error condition so you can collect complete data, including error messages, for diagnosis.

To configure the exception handling method:

 

Step	Command	Remarks
1.       Enter system view.	system-view	N/A
2.       (Optional.) Configure the exception handling method.	system-failure { maintain | reboot }	By default, the system reboots when an exception occurs.

 

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 WX1800H Series Access Controller 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 WX1800H Series Access Controller Fundamentals Command Reference.

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

Configuration procedure

Rebooting the device immediately

Task	Command	Remarks
Reboot the device immediately.	reboot	Available in user view.

 

Scheduling a reboot for the device

Task	Command	Remarks
Schedule a reboot.	·         Schedule a reboot to occur at a specific time or date: schedule reboot at time [ date ] ·         Schedule a reboot to occur after a delay: schedule reboot delay time	Use either command. By default, no reboot date or time or reboot delay time is specified. Available in user view. The most recent configuration takes effect if you execute the scheduler reboot at or scheduler reboot delay command multiple times.
