NIC Teaming & Switch Fault Tolerance

Unanswered Question
Aug 14th, 2007

We have two switches that each have a port connected to a Intel NIC in a Switch Fault Tolerance team. If the active link fails (switch A is powered off or cable unplugged) it works great and the second NIC goes active in the team.

My question: Since the (virtual) MAC address of the "teamed" adapter shows up on both switch ports, how is data redirected when the active link fails and the standby link takes over?

I have this problem too.

The switching from active link to backup link is ususally followed by gratuitous arp. Your host should send a request for ARP and reply back to it. Everyone on the network would now know how to get to the host the new way.

Thanks.
