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 roadtested, 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. Working and Certified contents are identical. Working Directory boot.cfg K2base.img K2release.img Etc. The switch runs from Working. Working Directory boot.cfg K2base.img K2release.img Etc. Certified Directory boot.cfg K2base.img K2release.img Etc. Certified Directory boot.cfg Hbase.img Hrelease.img Etc. When the switch is running from the /flash/working directory software, configuration changes can be saved via the write memory command. 24 Files and Directories June 2007
