Specifying the Active Boot Configuration File
To create or designate a new active boot configuration file for the switch,
use the BOOT CONFIG-FILE command in the Global Configuration mode.
Here is the format of the command;
boot config-file
filename
.cfg
The FILENAME.CFG parameter is the file name of the configuration file to
act as the active boot configuration file for the switch. This can be the
name of an entirely new file that does not exist yet in the file system, or an
existing file. The filename can be from 1 to 16 alphanumeric characters
and must include the “.cfg” extension. The filename is case sensitive. To
verify the name of an existing file, use the DIR command in the Privileged
Exec mode to display the names of the files in the file system.
The BOOT CONFIG-FILE command is unique from all the other
commands that are used to configure the parameters on the switch. After
you enter the command, the switch permanently remembers the filename
of the new active boot configuration file, without you having to enter the
WRITE command or the COPY RUNNING-CONFIG STARTUP-CONFIG
command. In fact, you probably will not want to enter either of those
commands after you specify a new active boot configuration file, because
that would cause the switch to overwrite the settings in the file with the
current settings.
After you enter the command, it does one of two things, depending on
whether the filename is of a new or an existing file. If the filename is of an
entirely new boot configuration file, the switch automatically creates it,
stores the current parameter settings in it, and finally designates it as the
active boot configuration.
If you specify the filename of an existing boot configuration file in the file
system, the switch marks it as the active boot configuration file, at which
point you need to make a choice.
To reconfigure the switch with the settings in the newly designated
active boot configuration file, reset the switch with the REBOOT
command in the Privileged Exec mode.
Caution
The switch does not forward packets while it is initializing its
management software. Some network traffic may be lost.
To overwrite the settings in the file with the switch’s current
settings, enter the WRITE or COPY RUNNING-CONFIG
STARTUP-CONFIG command in the Privileged Exec mode.
