Modifying the Startup Configuration

To store the configuration or changes you have made to your startup configuration in flash memory,

enter this privileged EXEC command:

Switch# copy running-config startup-config

Destination filename [startup-config]?

Building configuration...

This command saves the configuration settings that you made. If you fail to do this, your configuration

will be lost the next time you reload the system. To display information stored in the NVRAM section

of flash memory, use the show startup-config or more startup-config privileged EXEC command.

For more information about alternative locations from which to copy the configuration file, see

Appendix B, “Working with the Cisco IOS File System, Configuration Files, and Software Images.”

Modifying the Startup Configuration

These sections describe how to modify the switch startup configuration:

• Default Bootup Configuration, page 3-12

• Automatically Downloading a Configuration File, page 3-13

• Booting Up Manually, page 3-13

• Booting Up a Specific Software Image, page 3-14

• Controlling Environment Variables, page 3-15

See also Appendix B, “Working with the Cisco IOS File System, Configuration Files, and Software

Images,” for information about switch configuration files.

Default Bootup Configuration

Table 3-3 shows the default bootup configuration.

Table 3-3 Default Bootup Configuration

Feature Default Setting

Operating system software image The switch attempts to automatically boot up the system using information in the

BOOT environment variable. If the variable is not set, the switch attempts to load and

execute the first executable image it can by performing a recursive, depth-first search

throughout the flash file system.

The Cisco IOS image is stored in a directory that has the same name as the image file

(excluding the .bin extension).

In a depth-first search of a directory, each encountered subdirectory is completely

searched before continuing the search in the original directory.

Configuration file Configured switches use the config.text file stored on the system board in flash

memory.

A new switch has no configuration file.
