ZyXEL Communications NWA1123 Series User Manual page 164

Once your NWA1123 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 NWA1123 (whether through a management
interface or by physically turning the power off and back on), the NWA1123 uses the system-
default.conf configuration file with the NWA1123's default settings.
• If there is a startup-config.conf, the NWA1123 checks it for errors and applies it. If there are no errors,
the NWA1123 uses it and copies it to the lastgood.conf configuration file as a back up file. If there is an
error, the NWA1123 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 NWA1123 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 NWA1123 ignores any errors in the startup-config.conf file and applies
all of the valid commands. The NWA1123 still generates a log for any errors.
