Scheduling A Reload Of The Software Image - Cisco WS-C3020 Software Configuration Manual

Chapter 3 Assigning the Switch IP Address and Default Gateway
For complete syntax and usage information for the bootloader commands and environment variables, see
Note
the command reference for this release.
Table 3-4
Table 3-4 Environment Variables
Variable Bootloader 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.
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.
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.

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.

Specifies the Cisco IOS image to load during the
next bootup cycle. This command changes the
setting of the BOOT environment variable.

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.
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.
