be lost after the firewall reboots. In this case, you can maintain the current status of the firewall,
facilitating fault location.
Follow these steps to solve system faults:
To do…
Use the command…

method for the MPU

Optional

by default for the MPU.
NOTE:
•
Rebooting the MPU reboots the firewall.
•
If an interface module encounters software faults, the solving method is always reboot, which reboots the
failed module.
•
When system faults occur, the system fault solving method applies to only the failed module, and
rebooting the module does not interrupt the other modules.
Viewing the system fault solving method
Use the
display system-failure
command to display the system fault solving method.
<Sysname> display system-failure
System failure handling method: reboot
Saving the current configuration of the firewall
You can save the current configuration of the firewall in one of the following methods:
•
Fast saving: Executing the
save
command without the
safely
keyword. This mode saves the file more
quickly but is likely to lose the existing configuration file if the firewall reboots or the power fails
during the process. The fast saving mode is suitable for environments where the power supply is
stable.
•
Safe saving: Executing the
save
command with the
safely
keyword. The mode saves the file more
slowly but can retain the configuration file in the firewall even if the firewall reboots or the power
fails during the process. The safe saving mode is preferred in environments where a stable power
supply is unavailable or remote maintenance is involved.
