Troubleshooting system exceptions

Configuring the exception handling methods

You can use one of the following methods to handle system exceptions:

• reboot—The firewall reboots the failed MPU to recover from the error condition.

• maintain—The MPU stays in the error condition so you can collect complete data, including error

messages, for diagnosis. In this approach, you must manually reboot the firewall
