Note
Bit
is
by
default not present
on
the
CSC/3
or
CSCI4
processor
cards
Bit lOin
the configuration
register
controls
the
host portion of the
Internet
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
Bit 10
interacts
with
bit
14 which
controls
the
network and
subnet
portions
of the
broadcast address Table 5-2
shows
the
combined
effect
of
bits 10
and 14
This
effect is
overridden
by values
set in
NVRAM
using
the
ip
broadcast
address
command

Bits 11
and

determine
the

Table 5-3
shows
the

Bit 13
in the configuration
register
determines the system response
to
boot-load failure Setting
bit
13 causes the system
to
load operating software from
read-only
memory
ROM
after
five
unsuccessful
attempts
to
load boot
file
from
the
network
Clearing bit
13 causes
the system
to
continue
attempting to
load boot
file
from
the
network
indefinitely
By
factory
default bit 13
is
cleared
to
Bit 14
in the
configuration
register
controls
the
network
and subnet portions of
the
Internet broadcast
address
Setting bit
14 causes the system
to
include the
network
and subnet
portions of its
address
in
the broadcast
address
Clearing
bit 14 causes
the system
to set the entire
broadcast address
to
all
ones or
all zeros depending on the
setting
of
bit
10
By
factory default bit
14
is
cleared
to
See
Table
5-2
for
the
combined
effect
of
bits 10 and
14
Bit 15
in the configuration
register
controls
the
factory diagnostic
mode
in
the
system
Setting bit
15
causes the system
to
produce detailed
CPU
self-check
messages to
automatically
prompt for
interface addresses not look for
them on
the
network
to
not read configuration
files or
NYRAM
and
to automatically set to
diagnostic tracing
modes
using the
debug conmTtands
Clearing bit
15 the
factory default causes
the system
to
operate
normally
Bit 15
is also
used for
password
recovery
