Displaying device operating information

During daily maintenance or when a fault occurs, you need to view the running information of each functional module to locate the issue.

You can use one of the following methods to collect operating statistics for diagnostics and troubleshooting:

· Use separate display commands, such as display clock, display version, display device, and display current-configuration to collect operating information feature by feature or module by module.

· Use the display diagnostic-information command to save or display operating information for multiple or all features and hardware modules.

¡ Save operating information for multiple or all features and hardware modules:

<Sysname> display diagnostic-information

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

Please input the file name(*.tar.gz)[flash:/diag_H3C_20230504-154112.tar.gz]:diag.tar.gz

Diagnostic information is outputting to flash:/diag.tar.gz.

Please wait...

Save successfully.

To save storage space, this command automatically compresses the information before saving the information to a file. To view the file content:

# Use the tar extract archive-file command to extract the file.

# Use the gunzip command to decompress the extracted file.

# Use the more command to view the content of the decompressed file.

¡ Save operating information for multiple or all features and hardware modules:

Displaying transceiver module information and diagnosing transceiver modules

Displaying transceiver module information

Use the display transceiver interface command to display the key parameters of transceiver modules, including the transceiver module type, connector type, central wavelength of the transmit laser, signal transmission distance, and vendor name.

To display transceiver module information:

Task	Command	Remarks
Display key parameters of transceiver modules.	display transceiver interface [ interface-type interface-number ]	Available for all transceiver modules.

Diagnosing transceiver modules

The device provides the alarm and digital diagnosis functions for transceiver modules. When a transceiver module fails or is not operating correctly, you can perform the following tasks:

· Check the alarms on the transceiver module to identify the fault source.

· Examine the key parameters monitored by the digital diagnosis function, including the temperature, voltage, laser bias current, TX power, and RX power.

To diagnose a transceiver module:

Task	Command	Remarks
Display transceiver alarms.	display transceiver alarm interface [ interface-type interface-number ]	Available for all transceiver modules.

Saving the running configuration

IMPORTANT:

You must save the running configuration to a .cfg configuration file.

You can use one of the following methods to save the running configuration:

· Fast mode—Use the save command without the safely keyword. In this mode, the device directly overwrites the target next-startup configuration file. If a reboot or power failure occurs during this process, the next-startup configuration file is lost. You must specify a new startup configuration file after the device reboots.

· Safe mode—Use the save command with the safely keyword. Safe mode is slower than fast mode, but more secure. In safe mode, the system saves the configuration in a temporary file and starts overwriting the target next-startup configuration file after the save operation is complete. If a reboot or power failure occurs during the save operation, the next-startup configuration file is still retained. Use the safe mode if the power source is not reliable or you are remotely configuring the device.

To save the running configuration:

Task	Command	Remarks
Save the running configuration to a configuration file, without specifying the file as a next-startup configuration file.	save file-url [ all \| slot slot-number ]	Use either approach. Available in user view.
Save the running configuration to a configuration file in the root directory of the storage medium, and specify the file as a next-startup configuration file.	save [ safely ]

Task

Command

Remarks

Save the running configuration to a configuration file, without specifying the file as a next-startup configuration file.

save file-url [ all | slot slot-number ]

Use either approach.

Available in user view.

Save the running configuration to a configuration file in the root directory of the storage medium, and specify the file as a next-startup configuration file.

save [ safely ]

Rebooting the device or a module

CAUTION:

· If the main system software image file does not exist, do not use the reboot command to reboot the device. Specify the main system software image file first, and then reboot the device.

· The precision of the rebooting timer is 1 minute. 1 minute before the rebooting time, the device prompts "REBOOT IN ONE MINUTE" and reboots in one minute.

· If you are performing file operations when the device is to be rebooted, the system does not execute the reboot command for security.

To reboot the device or a module, use one of the following methods:

· Reboot the device at the CLI.

¡ 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 then power on the device. This method cuts off the power of the device forcibly, which might cause data loss and hardware damage. It is the least-preferred method.

To reboot a module or the device immediately:

Task	Command	Remarks
Reboot a module or the device immediately.	reboot [ slot slot-number ]	If you do not specify the slot slot-number option, the command reboots the device (including the MSUs and interface modules). Available in user view.

Task

Command

Remarks
