3.Managing System Files
The switch’s flash memory supports three types of system files that can be man-
aged by the CLI program, Web interface, or SNMP. The switch’s file system
allows files to be uploaded and downloaded, copied, deleted, and set as a start-
up file.
The three types of files are:
> Configuration — These files store system configuration information and are
created when configuration settings are saved. Saved configuration files can
be selected as a system start-up file or can be uploaded via TFTP to a server
for backup. A file named “Factory_Default_Config.cfg” contains all the system
default settings and cannot be deleted from the system. See “Saving or
Restoring Configuration Settings” on page 2-17 for more information.
> Operation Code — System software that is executed after boot-up, also
known as run-time code. This code runs the switch operation and provides the
CLI, Web and SNMP management interfaces. See “Managing Firmware” on
page 2-15 for more information.
> Diagnostic Code — Software that is run during system boot-up, also known
as POST (Power On Self-Test). This code also provides a facility to upload
firmware files to the system directly through the console port (see “Upgrading
Firmware via the Serial Port” on page A-2).
Due to the size limit of the flash memory, the switch supports only two operation
code files, and two diagnostic code files. However, you can have as many con-
figuration files as available flash memory space allows.
In the system flash memory, one file of each type must be set as the start-up file.
During a system boot, the diagnostic and operation code files set as the start-up
file are run, and then the start-up configuration file is loaded. Configuration files
can also be loaded while the system is running, without rebooting the system.
