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.
