Configuring the Exception Handling Method
When the system detects any software abnormality, it handles the situation with one of the following two
methods:
•
reboot: The system recovers itself through automatic reboot.
•
maintain: The system maintains the current situation, and does not take any measure to recover
itself. Therefore, you must recover the system manually, such as reboot the system. In case that the
system exception is difficult to reoccur, or some prompts that are printed during the failure are lost
after the reboot, use this method to maintain the abnormal state to locate problems and help to
recover the system.
Follow these steps to configure the exception handling method:

Rebooting a Device
When a fault occurs to a running device, you can remove the fault by rebooting the device with any of
the three methods:
•
Power on the device after powering it off, which is also called hard reboot or cold start. This method
impacts the device a lot. Powering off a running device will cause data loss and hardware damages.
It is not recommended.
•
Trigger the immediate reboot at the CLI.
•
Enable the scheduled reboot function at the CLI. You can set a time at which the device can
automatically reboot, or set a delay so that the device can automatically reboot within the delay.
The last two methods are command line operations. Reboot through command lines is also called hot
start, which is mainly used to reboot a device in remote maintenance without performing hardware
reboot of the device.
Follow the step below to immediately reboot a device at the CLI:
