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 switch will also create a file named
“startup1.cfg” that contains system settings for switch initialization, including
information about the unit identifier, and MAC address for the switch. 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 64 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" in the Web
Management Guide 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.
Saving or Restoring
Configuration
Settings
Configuration commands only modify the running configuration file and are not
saved when the switch is rebooted. To save all your configuration changes in
nonvolatile storage, you must copy the running configuration file to the start-up
configuration file using the “copy” command.
New startup configuration files must have a name specified. File names on the
switch are case-sensitive, can be from 1 to 31 characters, must not contain slashes
(\ or /), and the leading letter of the file name must not be a period (.). (Valid
characters: A-Z, a-z, 0-9, “.”, “-”, “_”)
There can be more than one user-defined configuration file saved in the switch’s
flash memory, but only one is designated as the “startup” file that is loaded when
the switch boots. The copy running-config startup-config command always sets
the new file as the startup file. To select a previously saved configuration file, use
the boot system config:<filename> command.
