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 [startup1.cfg]:
Flash programming started.
Flash programming completed.

To restore configuration settings from a backup server, enter the following
command:
1. From the Privileged Exec mode prompt, type “copy tftp startup-config” 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>.
