C HAPTER 2 | Initial Switch Configuration
Managing System Files
– 100 –
◆ 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.

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.
The maximum number of saved configuration files depends on available
flash memory. The amount of available flash memory can be checked by
using the dir command.
To save the current configuration settings, enter the following command:
1.
From the Privileged Exec mode prompt, type “copy running-config
startup-config” and press <Enter>.
2. Enter the name of the start-up file. Press <Enter>.
Console#copy running-config startup-config
