Files and Directories
May 2007
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 the
boot.cfg
file. However, subsequent boots may result in
your switch running from the
/flash/certified
directory. There-
fore, verifying the current running directory is a key step any
time you are configuring or monitoring the switch.
View the current directory by entering the
show running-
directory
command. For example:
-> show running-directory
CONFIGURATION STATUS
Running CMM : PRIMARY,
CMM Mode : DUAL CMMs,
Current CMM Slot : A,
Running configuration : WORKING,
Certify/Restore Status : CERTIFY NEEDED
SYNCHRONIZATION STATUS
Flash Between CMMs : NOT SYNCHRONIZED,
Running Configuration : SYNCHRONIZED,
NIs Reload On Takeover : ALL NIs
In this example, the switch is using the
/flash/working
direc-
tory.
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 is 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.
