Redundant network adapter
To obtain a redundant network connection to the LAN the P
ROCESSOR
can be equipped with multiple network
cards, which form an AFT (Adapter Fault Tolerance) team. A team consists of two or more network cards of the
same type. At least one of the cards must be a server adapter. The other ones can be server or desktop adapters.
Nevertheless we recommend to use for a redundant network adapter exclusively server adapters to achieve an
easy spare part handling. A team has an active (primary) adapter and one or more secondary adapters. The pri-
mary adapter is the network card that is used by default for data transfer. One of the secondary adapters is only
used if a fault occurs that prevents data transfer via the primary adapter. Whether the primary adapter is a server
adapter or not is of no importance but all cards of a team must be either exclusive 100 Mbps network cards or
exclusive 1000 Mbps network cards.
Configuration of an AFT team
To form a team of network cards the script
config
can be used. Therefore log in as
root
and change to the di-
rectory
/opt/MMT2686/ians
. The factory set password for root is
barco
.
eos login:
root
Password:
barco
[root@eos root] #
cd /opt/MMT2686/ians/
Start the script by entering
./config
:
[root@eos config] #
./config
The script will prompt you to select the network cards that are part of the team. The network cards are named
eth0
,
eth1
, etc. This numbering follows the reverse order of the PCI slots in which the cards are inserted,
please refer also to section
. Nevertheless it might be more convenient to first check the names of
the network cards by means of the
procfg
4.8.7 Network reporting utility (procfg)
Below you can read through a typical course of the configuration script expanded with comments giving more

to start with the configuration. In the following the script presents you a list with the available net-
work cards. You are prompted to select the network cards that form one team. The AFT team of T

A is
called
bteam0
. First enter the number of the network card that shall be the primary adapter. Anew a list is
shown but without the already selected card. Enter the number of the next member of the team. When all team
members are selected enter
0
to continue with the configuration.
