Problem with EtherChannel

I have created Etherchannel on Cisco 3524 between port 1-2, 3-4, and 5-6 and they are connected to 3 Dell Servers.

Server 1 (Dual Nic) connected to port 1-2

Server 2 (Dual Nic) connected to port 3-4

Server 3 (Dual Nic) connected to port 5-6

The problem is after a few minutes, the 3 servers would lose connection. Another few minutes later, the connection would be good. And another few minutes, the connection is lost. It is basically intermittent.

Port 24-25 are also Etherchannel and connected to another cisco switch, and it is working fine. The problem is only b/w servers and the switch.

I thought it was the Spanning tree, so I disabled these ports from learning (STP Learning = Disabled), but the results were the same.

Any Idea?

What mode are the channels in? On? Auto? Desireable?

You have enabled port teaming on the NICs on the Dell systems?

Yes, NICs are teamed properly.
