Certified Directory

Certified Directory

Intended for: Reliable, Tested configuration and image files. The switch will roll back to this software in the event of a system software error.

On reload: By default, the switch will use the software in this directory if there are any differences between the Working and Certified directories.

Saving changes: You cannot save configuration changes to the Certified directory. To save your changes, be sure that your switch is operating from the Working directory.

The software in the /flash/certified directory should be treated as the “gold master” for the switch. When you place configuration and image files in this directory, you are “certifying” them as tested and reliable. If the switch is running from the/flash/working directory and experiences a software problem, it will “roll back” to the last known good software in the/flash/certified directory on the next reboot.

How can I tell which directory the switch is currently using?

When you first boot the switch, the /flash/working directory is used; this allows you to save your initial configuration changes to theboot.cfg file. However, subsequent boots may result in your switch running from the/flash/certified directory. Therefore, verifying the current running directory is a key step any time you are configuring or monitoring the switch.

View the switch’s current running directory by entering the show running-directory command. For example:

->showrunning-directory

 

CONFIGURATION STATUS

: PRIMARY,

Running CMM

CMM Mode

: DUAL CMMs,

Current CMM Slot

: 1,

Running configuration

: WORKING,

Certify/Restore Status

: CERTIFY NEEDED

SYNCHRONIZATION STATUS

: SYNCHRONIZED,

Flash Between CMMs

Running Configuration

: NOT AVAILABLE,

Stacks Reload on Takeover: ALL STACKs (SW Activation)

In this example, the switch is using the /flash/working directory. For more information on theshow running-directory command output, refer to the “CMM Commands” chapter in theOmniSwitch CLI Reference Guide.
