Files and Directories

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 

 command.

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.

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.
