Modifying the Startup Configuration
To return to the default setting, use the no boot config-file global configuration command.
Booting Manually
By default, the switch automatically boots; however, you can configure it to manually boot.
Beginning in privileged EXEC mode, follow these steps to configure the switch to manually boot during
the next boot cycle:
To disable manual booting, use the no boot manual global configuration command.
Booting a Specific Software Image
By default, the switch attempts to automatically boot the system using information in the BOOT
environment variable. If this 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. In
a depth-first search of a directory, each encountered subdirectory is completely searched before
continuing the search in the original directory. However, you can specify a specific image to boot.
