Many thanks to the initial responses and the nice ndd scripts. Setting the ports to non-autonegotiate is actually what we have. What strikes us is communication between the single NIC'd servers are okay. It is only when a single NIC'd server communicates with a server that has dual interfaces that the performance is degraded. Netstat on the servers come out clean - port stats on the CISCO also come out clean (according to our brilliant NetAds...) Thanks.
