Managing System Files 2

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 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-configstartup-configcommand 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>.
