Configuration files on the switch are defined by their type, and contain the settings
and parameter values for the switch. When a configuration is referenced on the
switch, it is referenced by its configuration file type (such as Startup Configuration
or Running Configuration), instead of a file name that can be modified by the user.
Content can be copied from one file type to another, but the names of the file
types cannot be changed by the user. Other files on the switch include firmware
and log files, and are referred to as operational files.
Configuration files are text files that can be edited by a user in a text editor, such as
Notepad after they are copied to an external device, such as a PC.
The following types of configuration and operational files are found on the switch:
• Running Configuration—Contains parameters that are currently used by
the switch to operate. It is the only file type that is modified when you
change the parameter values on the switch.
If the switch is rebooted, the Running Configuration is lost. When the switch
is rebooted, this file type is copied from the Startup Configuration stored in
flash to the Running Configuration stored in RAM.
To preserve any changes that you made to the switch, you must save the
Running Configuration to the Startup Configuration, or another file type if
you do not want the switch to reboot with this configuration. If you have
saved the Running Configuration to the Startup Configuration, when the
switch is rebooted, it recreates a Running Configuration that includes the
changes made since the last time that the Running Configuration was saved
to the Startup Configuration.
• Startup Configuration—The parameter values that were saved by you by
copying another configuration (usually the Running Configuration) to the
Startup Configuration.
The Startup Configuration is retained in flash and is preserved when the
switch is rebooted. At this time, the Startup Configuration is copied to RAM
and identified as the Running Configuration.
• Backup Configuration—A manual copy of the parameter definitions for
protection against system shutdown or for the maintenance of a specific
operating state. You can copy the Mirror Configuration, Startup
Configuration, or Running Configuration to the Backup Configuration. The
Backup Configuration exists in flash and is preserved if the switch is
rebooted.
