Solving system faults
Solving system faults
When the system detects faults (such as system instruction faults, invalid addresses, data overflow,
null pointers, and division by zero operations) during the operation of the active MPU or standby
MPU, you can solve the problem in one of the following methods:
•
Reboot
—Rebooting the failed MPU so that the MPU restores to normal operational status.
•
Maintain
—Maintaining the current status of the failed MPU so that the system does not take
any restoration measures. Some software faults are hard to reproduce, and the printed
information will be lost after the router reboots. In this case, you can maintain the current status
of the router, facilitating fault location.
To solve system faults:

Viewing the system fault solving method
Use the
display system-failure
command to display the system fault solving method.

System failure handling method: reboot
Saving the current configuration of the router
You can save the current configuration of the router 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 router 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 router even if the router 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.
