ZyWALL (ZLD) CLI Reference Guide

• When the ZyWALL reboots, if the startup-config.conf file passes the error check, the ZyWALL 

keeps a copy of the startup-config.conf file as the lastgood.conf configuration file for you as a 
back up file. If you upload and apply a configuration file with an error, you can apply 
lastgood.conf to return to a valid configuration.

If there is not a startup-config.conf when you restart the ZyWALL (whether through a 
management interface or by physically turning the power off and back on), the ZyWALL uses the 
system-default.conf configuration file with the ZyWALL’s default settings.

If there is a startup-config.conf, the ZyWALL checks it for errors and applies it. If there are no 
errors, the ZyWALL uses it and copies it to the lastgood.conf configuration file. If there is an error, 
the ZyWALL 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 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 ignores any errors in the startup-config.conf file 

and applies all of the valid commands. The ZyWALL still generates a log for any errors. 

The following table explains the values you can input with the file manager commands.
