I have a dell server, which has two network interface cards.. i want to put network cables to both the NICs from two different switches on the same network, so that if any cable or switch goes disconnected the other one takes over the ip... .

i need to know, how can i assign the same ip to two NICs? if anybody could assist me.

best regards

You can assign different IPs to the two NICs if you use DNS aliases to point to both. That way if one goes down, the DNS will look at the other IP. This'll only work with publically routable IPs or NAT. AFAIK you can't assign the same IP to two different NICs on the same network as it'll cause problems. If you are talking about a fail-over solution for a server that's only on your local network, I don't know the answer :)

I believe you'll find your answer if you lookup:
"Multihomed server"

Multihomed just means multiple nics, however you can't assign identical IP's to 2 different nics, it (the server) wont let you do it anyway.

I'm pretty sure there's a solution for you there and it shouldn't take too much digging...

Hope that helps....
