Cisco Small Business SG200 Series 8-port Smart Switch 55

Files and File Types
The following types of configuration and operational files are found on the switch:
• Running Configuration—Parameters that are currently used by the switch
to operate. It is the only file type that is modified by you when the parameter
values are changed by using one of the configuration interfaces, and must be
manually saved to another file type, such as the Startup Configuration, to be
preserved after a reboot.
If the switch is rebooted, the Running Configuration is lost. When the switch
is rebooted, the Startup Configuration stored in the Flash is copied to the
Running Configuration stored in RAM.
• 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 any time the
switch is rebooted. When it is rebooted, 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 a Backup Configuration file. The
Backup Configuration exists in Flash and is preserved if the device is
rebooted.
• Mirror Configuration—A copy of the Running Configuration, created by the
switch after:
- The switch has been operating continuously for 24 hours.
- Configuration changes have been made to the Running Configuration in
the previous 24 hours, but have not been saved.
Only the switch can copy the Running Configuration to the Mirror
Configuration. However, you can copy from the Mirror Configuration to other
file types or to another device.
• Firmware—The operating system. More commonly referred to as the
image.
• Boot Code—Controls the basic system startup and launches the firmware
image.
