Seems that using the GUID instead of PORT_NUM didn't matter. After restarting the service, I was able to run osmtest and found all adapter hardware but had a timeout when it tried to identify the Cisco SFS 7000 switch. Only then, I found that the Cisco SFS 7000P has a built in IB subnet manager. What a waste of time. Thank you though.<BR>

Now on to the WinIB forum to figure out why they assign fake Ethernet MAC Addresses differently than OFED.<BR>
