Due to the size limit of the flash memory, the switch supports only one operation code file.
However, you can have as many diagnostic code files and configuration files as available
flash memory space allows. Transferring a new operation code file to the switch will
overwrite the existing file.
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 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.
The maximum number of saved configuration files depends on available flash memory,
with each configuration file normally requiring less than 20 kbytes. 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>.
