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

Rebooting a Device
When a fault occurs to a running device, you can remove the fault by rebooting the AP, depending on
the actual situation.
You can reboot a device following any of the three methods:
z
Power on the AP after powering it off, which is also called hard reboot or cold start. This method
impacts the AP a lot. Powering off a running device will cause data loss and hardware damages. It
is not recommended.
z
Trigger the immediate reboot through command lines.
z
Enable the scheduled reboot function through command lines. You can set a time at which the AP
can automatically reboot, or set a delay so that the AP 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 AP.
Follow the step below to reboot a device through command lines immediately:
