ZyXEL Communications NWA Series User Manual page 234

Once your Zyxel Device is configured and functioning properly, it is highly recommended that you back
up your configuration file before making further configuration changes. The backup configuration file
will be useful in case you need to return to your previous settings.
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.
