Configuration File Flow at Restart
• If there is not a startup-config.conf when you restart the ZyWALL/USG (whether through a
management interface or by physically turning the power off and back on), the ZyWALL/USG
uses the system-default.conf configuration file with the ZyWALL/USG's default settings.
• If there is a startup-config.conf, the ZyWALL/USG checks it for errors and applies it. If there
are no errors, the ZyWALL/USG uses it and copies it to the lastgood.conf configuration file as a
back up file. If there is an error, the ZyWALL/USG generates a log and copies the startup-
config.conf configuration file to the startup-config-bad.conf configuration file and tries the
existing lastgood.conf configuration file. If there isn't a lastgood.conf configuration file or it
also has an error, the ZyWALL/USG applies the system-default.conf configuration file.
• You can change the way the startup-config.conf file is applied. Include the setenv-startup
stop-on-error off command. The ZyWALL/USG ignores any errors in the startup-config.conf
file and applies all of the valid commands. The ZyWALL/USG still generates a log for any errors.
