We have 2 Cisco 3750 stacked and we are trying to team 1 HP server on it.

We have observed that since the same MAC is learnt on 2 switch ports, the port is flapping.

What is the way out?

Set the NICs to failover versus load balance.

Hope that helps

I would set up lacp etherchannel between the HP server and the switch stack in a cross-stack configuration. I know HP servers support 802.3ad lacp because I have many of them running in this fashion. Lacp will control the load-balancing and will only allow 1 mac-address to be used in the nic team.
