Automatically Downloading a Configuration File

You can automatically download a configuration file to your switch by using the DHCP-based
autoconfiguration feature. For more information, see the
Autoconfiguration" section on page

Specifying the Filename to Read and Write the System Configuration

By default, the Cisco IOS software uses the file config.text to read and write a nonvolatile copy of the
system configuration. However, you can specify a different filename, which will be loaded during the
next boot-up cycle.
Beginning in privileged EXEC mode, follow these steps to specify a different configuration filename:
Command
Step 1
configure terminal
Step 2 boot config-file flash:/file-url
Step 3 end

shows the default boot-up configuration.
Default Setting
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.
Configured switches use the config.text file stored on the system board in flash
memory.
A new switch has no configuration file.
