Linksys LGS308 User Manual page 194

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 memory, 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 memory and is preserved when the device is
rebooted. At this time, the Startup Configuration is copied to RAM and identified as the
Running Configuration.
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
Startup Configuration, or Running Configuration to a Backup Configuration file. The
Backup Configuration exists in flash memory and is preserved if the device is rebooted.
• Firmware—The program that controls the operations and functionality of the device. More
commonly referred to as the image.
• Boot Code—Controls the basic system startup and launches the firmware image.
Flash Log—SYSLOG messages stored in Flash memory.
•
File Actions
