Managing System Files
The switch’s flash memory supports three types of system files that can be managed
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 — This file stores system configuration information and is 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 3-19 for more information.
• Operation Code — System software that is executed after boot-up, also known as
run-time code. This code runs the switch operations and provides the CLI and web
management interfaces. See “Managing Firmware” on page 3-17 for more
information.
• Diagnostic Code — Software that is run during system boot-up, also known as
POST (Power On Self-Test).
Due to the size limit of the flash memory, the switch supports only two operation
code files. However, you can have as many diagnostic code files and configuration
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.
Note that configuration files should be downloaded using a file name that reflects the
contents or usage of the file settings. If you download directly to the running-config,
the system will reboot, and the settings will have to be copied from the
running-config to a permanent file.
