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. 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
Startup configuration file name []: startup

To restore configuration settings from a backup server, enter the following
command:

and press <Enter>.
2. Enter the address of the TFTP server. Press <Enter>.
3. Enter the name of the startup file stored on the server. Press <Enter>.
4. Enter the name for the startup file on the switch. Press <Enter>.
