BOOT CONFIG-FILE
Syntax
boot config-file
filename
.cfg
Parameter
filename
Specifies the name of a boot configuration file that is to act as the
active boot configuration file on the switch. The filename can be
from 1 to 16 alphanumeric characters. The extension must be
“.cfg”.
Mode
Global Configuration mode
Description
Use this command to designate the active boot configuration file on the
switch. The switch uses the file to save its parameter settings when you
issue the WRITE or COPY RUNNING-CONFIG STARTUP-CONFIG
command, and to restore its parameter settings when you reset or power
cycle the unit.
To create a new active boot configuration file, enter a new filename in the
command. The command automatically creates the file, updates it with the
current settings of the switch, and designates it as the active boot
configuration file.
To specify an existing boot configuration file as the new active file on the
switch, include the file’s name in the command. The switch marks it as the
active boot configuration file. Afterwards, do one of the following:
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.
