Performing Switch Setup Configuration
Information About Performing Switch Setup Configuration
Scheduled Reload of the Software Image
You can schedule a reload of the software image to occur on the switch at a later time (for example, late at night or during
the weekend when the switch is used less), or you can synchronize a reload network-wide (for example, to perform a
software upgrade on all switches in the network).
Note: A scheduled reload must take place within approximately 24 days.
You have these reload options:

Software reload to take effect in the specified minutes or hours and minutes. The reload must take place within
approximately 24 days. You can specify the reason for the reload in a string up to 255 characters in length.

Software reload to take place at the specified time (using a 24-hour clock). If you specify the month and day, the
reload is scheduled to take place at the specified time and date. If you do not specify the month and day, the reload
takes place at the specified time on the current day (if the specified time is later than the current time) or on the next
day (if the specified time is earlier than the current time). Specifying 00:00 schedules the reload for midnight.
The reload command halts the system. If the system is not set to manually boot up, it reboots itself.
If your switch is configured for manual booting, do not reload it from a virtual terminal. This restriction prevents the switch
from entering the boot loader mode and thereby taking it from the remote user’s control.
Table 14 Environment Variables
Variable Boot Loader Command Cisco IOS Global Configuration Command
BOOT set BOOT filesystem :/ file-url ...
A semicolon-separated list of executable files to
try to load and execute when automatically
booting. If the BOOT environment variable is not
set, the system attempts to load and execute the
first executable image it can find by using a
recursive, depth-first search through the flash
file system. If the BOOT variable is set but the
specified images cannot be loaded, the system
attempts to boot the first bootable file that it can
find in the flash file system.
boot system f ilesystem:/file-url ...
Specifies the Cisco IOS image to load during the
next boot cycle. This command changes the
setting of the BOOT environment variable.
MANUAL_BOOT set MANUAL_BOOT yes
Decides whether the switch automatically or
manually boots up.
Valid values are 1, yes, 0, and no. If it is set to no
or 0, the boot loader attempts to automatically
boot up the system. If it is set to anything else,
you must manually boot up the switch from the
boot loader mode.
boot manual
Enables manually booting up the switch during
the next boot cycle and changes the setting of the
MANUAL_BOOT environment variable.
The next time you reboot the system, the switch
is in boot loader mode. To boot up the system,
use the
boot flash: filesystem :/ file-url boot loader
command, and specify the name of the bootable
image.
CONFIG_FILE set CONFIG_FILE flash:/ file-url
Changes the filename that Cisco IOS uses to
read and write a nonvolatile copy of the system
configuration.
boot config-file flash:/ file-url
Specifies the filename that Cisco IOS uses to read
and write a nonvolatile copy of the system
configuration. This command changes the
CONFIG_FILE environment variable.
