When a configuration is referenced on the device, it is referenced by its configuration file type (such as
Startup Configuration or Running Configuration), as opposed to a file name that can be modified by the
user.
Content can be copied from one configuration file type to another, but the names of the file types cannot be
changed by the user.
Other files on the device include firmware, boot code, and log files, and are referred to as operational files.
The configuration files are text files and can be edited in a text editor, such as Notepad after they are copied
to an external device, such as a PC.
Files and File Types
The following types of configuration and operational files are found on the device:
• Running Configuration—Contains the parameters currently being used by the device to operate.
This is the only file type that is modified when you change parameter values on the device.
If the device is rebooted, the Running Configuration is lost. The Startup Configuration, stored in Flash,
overwrites the Running Configuration, stored in RAM.
To preserve any changes you made to the device, you must save the Running Configuration to the
Startup Configuration, or another file type.
• Startup Configuration—The parameter values that were saved by copying another configuration
(usually the Running Configuration) to the Startup Configuration.
The Startup Configuration is retained in Flash and is preserved when the device is rebooted. At this
time, the Startup Configuration is copied to RAM and identified as the Running Configuration.
• Mirror Configuration—A copy of the Startup Configuration, created by the device when the following
conditions exist:
- The device has been operating continuously for 24 hours.
- No configuration changes have been made to the Running Configuration in the previous 24 hours.
- The Startup Configuration is identical to the Running Configuration.
Only the system can copy the Startup Configuration to the Mirror Configuration. However, you can
copy from the Mirror Configuration to other file types or to another device.
The option of automatically copying the Running Configuration to the mirror configuration can be
disabled in the Configuration Files Properties page.
• Backup Configuration—A manual copy of a configuration file used for protection against system
shutdown or for the maintenance of a specific operating state. You can copy the Mirror Configuration,
