Hi gurus,

Thanks to all (and especially Ralph Wegner and Thomas M. Payerle)

They advised me to use netconfig and/or netsetup programs to make this
change ...



My Question was .................................

Dear Admins,
I have an
Alpha 4100
2 GB RAM DU4.0D

My alpha has 2 NET cards
1- ATM card: it is connected to ATM Gigaswitch box via fiber medium. It has
an IP address and all tcp/ip connections are done on it.
2- 10 Mbps Erhernet card. It is used by LAT terminal servers to get
connected to my alpha. It has no IP address.

I want to remove the ATM card and make the ethernet card THE ONLY CARD on
the machine.

I think making the ATM card down (with ifconfig) and giving the IP address
(of ATM card) to the ethernet card will be enough.


What should I do so that ethernet card can do both its and ATM card's
functions ? (In the UNIX side ...)
Can there be some adjustments on the network active devices (switches
etc...)

What can be the problems ?
