Hey Seth, thanks for the reply. I don't use the iLO port, so I didn't look at it's MAC within the BIOS, however my issue isn't that the MACs are the same within a physical machine. They're different, just like all the other HP gear ... It's that I have two machines that the MACs are identical. Like Server-A's NIC1 matches Server-B's NIC1 ... And the same goes for NIC2. Heck, maybe even their iLO matches too. I just re-read my post and I can see where maybe I didn't explain it properly. Yesterday was a long day ... I guess it's not that big of deal now, I resolved it rather quickly by putting Server-B on another VLAN. On 1/2/11 12:56 AM, "Seth Mattinen" <sethm () rollernet us> wrote:

Not spoofd and the OS drivers are not mucking with them ... They¹re burned-in I triple checked them in their respective BIOS screen. I acquired these two machines at different times and both were from the grey market. The ³What the ...² is sitting fresh in my mind ... How can this be? In the last 15 years of being in IT, I have never encountered a ³burned-in² duplicated MACs across two physically different machines. What are the odds, that HP would dup¹d them and that both would eventually end up at my shop? Or maybe this type of thing isn¹t big of deal... ?None of the HP servers I have contain duplicate MAC addresses. (I just looked through all the iLO2 cards to make sure I wasn't lying.) I'll send you some details offlist. ~Seth
