Can I save changes to the Certified directory?
No. The /flash/certified directory is intended to store only
tested, reliable configuration and image files. Configuration
changes must be saved to the boot.cfg file in the
/flash/working directory. Once those changes have been road-
tested, the contents of the /flash/working directory can be
copied to the /flash/certified directory via the
copy working certified command.
What happens when the switch boots?
During the boot process, the switch compares the contents of
the /flash/working and /flash/certified directories. Based on
this comparison, the switch determines which directory to use
as its running software.
Working and Certified Are Identical
If the software in the /flash/working and /flash/certified
directories are completely identical, the switch considers the
software in both directories to be equally reliable. In this case,
the switch will run from the /flash/working directory.
When the switch is running from the /flash/working directory
software, configuration changes can be saved via the
write memory command.
