You are installing a new device to replace a device that failed. The configuration of the failed device
is stored on a networked server, and the new device has an RXBOOT image installed. Under which
condition does the streamlined Setup mode fail?
A.
The last four bits of the configuration register are not equal to the decimal value 0 or 1.
B.
The startup configuration file was deleted.
C.
Bit 6 is set in the configuration register.
D.
The startup configuration is corrupt.
The lowest four bits of the configuration register (bits 3, 2, 1, and 0) form the boot field. The boot
field determines if the router boots manually, from ROM, or from Flash or the network.
To change the boot field value and leave all other bits set to their default values, follow these
guidelines:
•
If you set the configuration register boot field value to 0x0, you must boot the operating system
manually with the boot command.
•
If you set the configuration register boot field value to 0x1, the router boots using the default ROM
software.
•
If you set the configuration register boot field to any value from 0x2 to 0xF, the router uses the
boot field value to form a default boot filename for booting from a network server.
For more information about the configuration register bit settings and default filenames, refer to the
appropriate router hardware installation guide.
