NIC Teaming ADDR_FLAP

[Ayman Altounji]

Compaq DL380 is configure with network teaming (redundancy not load balancing). The Server has the latest patches etc (Compaq and NT). There are no errors reported from the compaq software, send or receive. The network connectivity seem OK. No NT errors in the NT Event log. But the Cisco 2912 switch sees multiple MAC addresses from the same link (an address flap). If I unplugg one of the network cables the problem abvoiusly stops.

Both the cisco 2912 and the Compaq NIC are set for full duplex.

I also have I have another 8 x DL380 with same configuration using the same Cisco 2912 Switches. 4 of these server are reporting the same errors. The only common thing is that they all run IIS4. The reason I noticed this is that A cisco content switch (CSS), which monitors specific services on these servers, reported the the service was "dying".

Any advice would be greatly appreciated.
