Network Proc.
2
Set the Traffic IP Address of the Online Modem only.
3
Verify that the Traffic IP Address also appears on the Offline Modem.
The
Traffic
IP
Address
for
both
modems
is
“shared”,
but
only
the
Online
Modem
activates
the
Traffic
IP
Address.
In
addition,
each
modem
must
be
given
a
unique
Management
IP
Address
that
does
not
float
with
Online/Offline
status.
The
modem
uses
the
Management
IP
Addresses
to
mirror
parameters.
Upon
boot
up,
the
Offline
Modem
requests
a
parameter
update
from
the
Online
Modem.
The
Online
Modem
sends
the
parameter
update
to
the
Offline
Modem
using
the
LAN.
In
addition,
when
you
save
the
online
Network
Processor
parameters,
the
Online
Modem
sends
parameter
updates
to
the
Offline
Modem.
The
Offline
Modem
receives
parameter
updates,
updates
itself,
and
then
saves
those
updated
parameters
in
Flash
memory.
Follow
these
steps
to
enter
the
Management
IP
Address
on
the
Online
Modem:

Set the Management IP Address (Mgmt IP) of the Online Modem.
Follow

2
Set the Management IP Address (Mgmt IP) of the Offline Modem.
The
Management
IP
Addresses
must
be
unique
for
both
modems,
but
must
be
on
the
same
subnet
.
The
Online
Modem
always
sends
a
gratuitous
ARP
for
the
Traffic
IP
Address
when
it
comes
online.
This
causes
networked
device
on
the
LAN
to
update
their
ARP
tables
and
start
sending
their
IP
traffic
to
the
Online
Modem.
The
Offline
Modem
always
filters
all
IP
packets
received
from
the
WAN
that
are
destined
to
LAN.
This
keeps
duplicate
IP
packets
off
the
LAN.
In
addition,
the
offline
Network
Processor
changes
all
its
WAN
routes
so
that
their
“Next
Hop
IP
Address”
is
the
Online
Modem’s
management
IP
address.
This
allows
remote
access
to
the
offline
Network
Processor
from
both
the
LAN
interface
and
WAN
interface.
