DETAILED STEPS
To return to the default setting, use the no boot system global configuration command.
EXAMPLE
Switch(config)# boot system flash:/images/new-ios-image
Switch(config)# end
Controlling Environment Variables
With a normally operating switch, you enter boot loader mode only through a switch console connection
configured for 9600 bps. Unplug and then reconnect the switch power cord. After the switch performs
POST, the switch begins the autoboot process. The boot loader prompts the user for a break key character
during the boot-up sequence, as shown in this example:
***** The system will autoboot in 5 seconds *****
Send a break key to prevent autobooting.
Note You can interrupt the automatic boot process by pressing the break key on the console after the flash file
system has initialized. If you configured the switch to manually boot from boot loader mode, you cannot
use the break key to interrupt the boot process. The default configuration is the automatic boot process.
For more information, see the command reference listed in the “Related Documents” section on
page 2-25.
The break key character is different for each operating system.
• On a SUN work station running UNIX, Ctrl-C is the break key.
Command Purpose
Step 1
configure terminal Enter global configuration mode.
Step 2
boot system filesystem:/file-url Configure the switch to boot a specific image in flash memory
during the next boot cycle.
• For filesystem:, use flash: for the system board flash device.
• For file-url, specify the path (directory) and the name of the
bootable image.
Filenames and directory names are case sensitive.
Step 3
end Return to privileged EXEC mode.
Step 4
show boot Verify your entries.
The boot system global command changes the setting of the
BOOT environment variable.
During the next boot cycle, the switch attempts to automatically
boot the system using information in the BOOT environment
variable.
Step 5
copy running-config
startup-config
(Optional) Save your entries in the configuration file.
