Using the Monitor
Utility

If your bridge/router is unable to boot from the software, you can attach
a console to the console port and access the firmware monitor utility.

To access the monitor utility from the software, enter:

MONitor

CAUTION:

The monitor utility stops the software from running, and you

must reset the bridge/router to exit the firmware.

The following commands are available from the monitor utility:

Boot

Syntax

BT [<filename> [<config directory>]]

Description

The BT command allows you to reboot or to override the default boot
path configured in the firmware by the monitor or by the SysconF
command in the software. If you enter a new boot path, the firmware
parameter is updated to reflect the new path.

If you do not enter a filename or a configuration file directory, the system
attempts to boot from boot.68k in the /primary directory. If there is an
