Scheduling a Reload of the Software Image
You can schedule a reload of the software image to occur only on an LRE 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.

Configuring a Scheduled Reload

To configure your switch to reload the software image at a later time, use one of these commands in
privileged EXEC mode:

5-16
Boot Loader Command
set CONFIG_FILE flash:/file-url
Changes the filename that the software uses
to read and write a nonvolatile copy of the
system configuration.
set CONFIG_BUFSIZE size
Changes the buffer size that the software
uses to hold a copy of the configuration file
in memory. The configuration file cannot be
larger than the buffer size allocation. The
range is from 4096 to 524288 bytes.
reload in [hh:]mm [text]
This command schedules a reload of the software to take affect 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.
reload at hh:mm [month day | day month] [text]
This command schedules a reload of the software 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.

Cisco IOS Global Configuration Command
boot config-file flash:/file-url
Specifies the filename that the software uses
to read and write a nonvolatile copy of the
system configuration. This command changes
the CONFIG_FILE environment variable.
boot buffersize size
Specifies the size of the file system-simulated
NVRAM in flash memory. The buffer holds a
copy of the configuration file in memory. This
command changes the setting of the
CONFIG_BUFSIZE environment variable.
You must reload the switch by using the
reload privileged EXEC command for this
command to take effect.
