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 — 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 se ttings
and cannot be deleted from the system. See “Saving or Restoring
Configuration Settings” on page 2-18 for more information.
•Operation Code — System software that is executed after boot-up,
also known as run-time code. This code runs the switch operatio n and
provides the CLI, Web and SNMP management interfaces. See
“Managing Firmware” on page 2-16 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 Se rial Port” on page
A-2.
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. Configuration files can also be loaded while the system is r unning,
without rebooting the system.
