Hi, I am new in AIX. I've just got a used server H80 which contains 4
ethernet cards (#2968). I have a fresh install of V4.3.3 with ML11. I
manage to configure en0 with 192.168.1.90, it works fine with all the
connection. However, I tried to configure the other 3 network cards, with
192.168.1.91, 92, and 93. None of these 3 cards work. I can ping the IP of
these 91, 92, 93.

How to make these 3 cards work? Thanks.

How did you configure them? If you used the same smit screen as the
first interface, that is your problem. First, get rid of all but the
first interface:

ifconfig down detach en1
" en2
" en3

Now use the "Further Configuration" menu option just below "Minumum
Configuration". I believe next you use "Network Interface Selection",
then I think it's "Change / Show a Standard Network Interface". I could
be wrong about which exact menu it is, all I know for sure is that you
don't use the same smit menu to add adapters after the initial one is
configured.

Rickie,

Try putting each card on its own subnet. If all cards are on the
192.168.1.X network how will the routing table know which card to use to
send packets to other IP addresses on the network? Putting multiple cards
on the same subnet makes no sense. Try 192.168.1.90, 192.168.2.90,
192.168.3.90, and 192.168.4.90 with a subnet mask of 255.255.255.0. You
will have four separate networks and be able to use all your cards.

What do you mean by "None of these 3 cards work"? What did you do and
what did you see? Nathan's response is correct if you want to have each
on a different subnet, which is *sometimes* synonymous with the same
VLAN. If you want to use them *all* on the same subnet, then you might
consider using AIX etherchannel support.
