Troubleshooting system exceptions
Configuring the exception handling methods
You can use one of the following methods to handle system exceptions:
• reboot—The UTM device reboots to recover from the error condition.
• maintain—The UTM device stays in the error condition and does not take any measure to recover
itself, so you can collect complete data, including error messages, for diagnosis.
To configure the exception handling method:
Step Command Remarks
1. Enter system view. system-view N/A
2. Configure the exception
handling method for the
system.
system-failure { maintain |
reboot }
Optional.
By default, the system uses the
reboot method when an exception
occurs.
Displaying the exception handling method
Use the display system-failure command to display the exception handling method.
