Configuration File Flow at Restart
• If there is not a startup-config.conf when you restart the Zyxel Device (whether through a
management interface or by physically turning the power off and back on), the Zyxel Device uses the
system-default.conf configuration file with the Zyxel Device's default settings.
• If there is a startup-config.conf, the Zyxel Device checks it for errors and applies it. If there are no
errors, the Zyxel Device uses it and copies it to the lastgood.conf configuration file as a back up file. If
there is an error, the Zyxel Device 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 Zyxel Device 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 Zyxel Device ignores any errors in the startup-config.conf file and
applies all of the valid commands. The Zyxel Device still generates a log for any errors.
