Scenario 2: Running Configuration Saved to Working Directory
The network administrator recreates Switch X’s running configuration and immediately saves the running
configuration to the working directory.
In another mishap, the power to the switch is again interrupted. The switch reboots from certified direc-
tory, overwriting all of the changes in the running configuration, and rolls back to the certified directory
(which in this case is the factory settings). However, since the configuration file was saved to the working
directory, that file is still in the working directory and can be retrieved. Since the working and certified
directories are not exactly the same, the switch is running from the certified directory.
This is illustrated in the diagram below:
Running Configuration Saved to Working Directory
It is important to note that in the above scenario, the switch is using the configuration file from the certi-
fied directory, not the working directory. The changes made and saved to the working directory are not in
effect. The switch can be booted from the working directory using reload working command.

1. Switch boots
from certified
directory using
factory configura-
tion settings.
Since the working
and certified
directories are the
same, it will be
running from the
working direc-
tory.
2. Changes are
made to the run-
ning configura-
tion and stored in
the running con-
figuration, then
saved to the work-
ing directory.
3. Power is inter-
rupted and the
switch goes down.
4. Switch reboots
from certified
directory using
factory configura-
tion settings; saved
configuration file
is still in the work-
ing directory.
Since the working
and certified direc-
tories are not the
same, it will be
running from the
certified directory.
