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:

R W C

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.

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.
