Hello,
my question is directed to Intel NIC developers - we (CDN77) are using your X520-DA2 cards in thousands of servers - we have discovered that two different X520-DA2 NICs we have in our network do use the SAME MAC address.
The conflicting MAC is 00:1b:21:bc:32:15.
Is this something what 'can happen from time to time'? It would be a real flaw in the design - this makes makes me think the duplicate MAC is caused by some Chinese copy of the genuine Intel NIC.
You can imagine what mess can this cause.
If it helps, I can send more detail information regarding both NICs.
Thank you!
