Then configure
Management LAN Interface
(
eth1
) with the same IP setting that you used for the
main
Network Interface
(
eth0
) to ensure transparent redundancy.
In this mode, Network 2 (eth1) is available as the transparent back-up port to Network 1 (eth0) for
accessing the management network. Network 2 will automatically and transparently take over the work
of Network 1 if for any reason Network 1 becomes unavailable. And when Network 1 becomes available
again, it takes over the work again.

Dial-Out Failover
The Console Servers can be configured so a dial-out PPP connection is automatically set up in the event
of a disruption in the principal management network:
When configuring the principal network connection in
System: IP
, specify
Internal Modem
(or the
Dial Serial DB9
if using an external modem on the Console port) as the
Failover Interface
to be used
when a fault has been detected with Network1 (eth0).
Specify the
Probe Addresses
of two sites (the
Primary
and
Secondary
) that the Console Server is to
ping
to determine if Network1 is still operational.
Select the
System: Dial
menu option and the port to be configured (
Serial DB9 Port
or
Internal
Modem Port
).
Select the
Baud Rate
and
Flow Control
that will communicate with the modem.
Note
You can further configure the console/modem port (
e.g.
to include
modem init
strings) by editing
/etc/mgetty.config
files as described in Chapter 13.
Check the
Enable Dial-Out Access
box and enter the access details for the remote PPP
server to be called.
