Configuration Bit Meanings
Bit 8
Bit 8 controls the console Break key. Setting bit 8 (the factory default) causes the processor to ignore the
console Break key. Clearing bit 8 causes the processor to interpret Break as a command to force the
system into the bootstrap monitor, halting normal operation. A Break can be sent in the first 60 seconds
while the system reboots, regardless of the configuration settings.
Bit 10 and Bit 14
Bit 10 controls the host portion of the IP broadcast address. Setting bit 10 causes the processor to use all
zeros; clearing bit 10 (the factory default) causes the processor to use all ones. B it 10 interacts with bit
14, which controls the network and subnet portions of the IP broadcast address.

Bit 13
Bit 13 determines the server response to a bootload failure. If boot commands are in the configuration
file, the router software processes each boot command in sequence until the process is successful or the
end of the list is reached. If the end of the list is reached without a file being successfully booted, the
router will retry the netboot commands up to six times if bit 13 of the configuration register is set,
otherwise it will load the operating system software available in ROMmon. If bit 13 is not set, the router
will continue to netboot images indefinitely. The default setting for bit 13 is 0. If bit 13 is set, the system
boots the boot helper image found in boot flash memory without any retries.
