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 types of files are:
◆
Configuration — This file type 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 FTP/TFTP to a server for backup. The file named
“Factory_Default_Config.cfg” contains all the system default settings
and cannot be deleted from the system. If the system is booted with
the factory default settings, the master unit will also create a file
named “startup1.cfg” that contains system settings for stack
initialization, including information about the unit identifier, MAC
address for each unit. The configuration settings from the factory
defaults configuration file are copied to this file, which is then used to
boot the switch. See "Saving or Restoring Configuration Settings" on
page 83 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
System Files" on page 113 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. The switch
has a total of 32 Mbytes of flash memory for system files.
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.
