Configuration File Flow at Restart
• If there is not a startup-config.conf when you restart the ISG50 (whether through a
management interface or by physically turning the power off and back on), the ISG50 uses the
system-default.conf configuration file with the ISG50’s default settings.
•If there is a startup-config.conf, the ISG50 checks it for errors and applies it. If there are no
errors, the ISG50 uses it and copies it to the lastgood.conf configuration file as a back up file. If
there is an error, the ISG50 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
ISG50 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 ISG50 ignores any errors in the startup-config.conf file
and applies all of the valid commands. The ISG50 still generates a log for any errors.
