Scheduling a Reload of the Software Image
Note
For complete syntax and usage information for the bootloader commands and environment variables, see
the command reference
for this release.
Table 3-4
describes the function of the most common environment variables.
Scheduling a 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.
Table 3-4
Environment Variables
Variable
Bootloader 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 up the switch. 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 up 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 bootup 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 bootloader attempts to automatically
boot up the system. If it is set to anything else,
you must manually boot up the switch from the
bootloader mode.
boot manual
Enables manually booting up the switch during
the next bootup cycle and changes the setting of
the MANUAL_BOOT environment variable.
The next time you reboot the system, the switch is
in bootloader mode. To boot up the system, use the
boot
flash:
filesystem
:/
file-url
bootloader
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.
