bof
Syntax bof
Context <root>
Description This command creates or edits the boot option file (BOF) for the specified local storage device.
A BOF file specifies where the system searches for runtime images, configuration files, and other
operational parameters during system initialization.
BOF parameters can be modified. Changes can be saved to a specified compact flash. The BOF must
be located in the root directory of either an internal or external compact flash local to the system and
have the mandatory filename of bof.cfg.
When modifications are made to in-memory parameters that are currently in use or operating, the
changes are effective immediately. For example, if the IP address of the management port is changed,
the change takes place immediately.
Only one entry of the BOF configuration command statement can be saved once the statement has
been found to be syntactically correct.
When opening an existing BOF that is not the BOF used in the most recent boot, a message is issued
notifying the user that the parameters will not affect the operation of the node.
No default boot option file exists. The router boots with the factory default boot sequence and
options.
Default none
save
Syntax save [cflash-id]
Context bof
Description This command uses the boot option parameters currently in memory and writes them from the boot
option file to the specified compact flash.
The BOF must be located in the root directory of the internal or external compact flash drives local to
the system and have the mandatory filename of bof.cfg.
If a location is not specified, the BOF is saved to the default compact flash drive (cf3:) on the active
CPM (typically the CPM in slot A, but the CPM in slot B could also be acting as the active CPM).
The slot name is not case-sensitive. You can use upper or lowercase “A” or “B”.
