load balancing in passport 8600

[RCNetAdmin]

Hello,

I have been trying to make a load balancing between two ports on the passport 8600.
My problem is that the two servers are disconnected all the time.
I guess because of the MAC address.
On the network this two servers are represented as one MAC.
So the passport can handle it.
With a normal baystack-450 it works ok.

How can I solve this problem?

Thanks.

We have this set-up for several NT cluster servers and have no issues with it.

What type of servers and NIC's?

Both ports in same VLAN?

Speed/Duplex set correctly on both ports? (very important to hard-code on both sides, server and switch, because several vendor NIC's don't auto-negotiate quite right with the 8600)

Thanks for you respose

The servers NIC’s are Intel pro-set 1000.
I have checked the server’s connection and they are connected to the same VLAN with 100 FULL on both sides.

Are we dealing with three IP addreses here? One for each server and one for the "cluster"?

Yes.

Seems like the normal setup. The only time I saw problems with this is when our server administrators were setting-up teaming and used etherchannel as the method; it's a Nortel switch not Cisco so that gave them all kinds of problems until they changed it.
