As I'm beginning to utilize my second port on some of my Intel X520-T2's, I noticed that one of them has the same MAC address assigned to both ports!?! I checked my other X520-T2s (I have 14 of them), and this is the only one showing up like this. Has anyone seen this before, and, is there a way to fix it?
Theoretically, I can change the MAC address in software, but generally that involves saying: change MAC address X to MAC address Y, but I think that could lead to interesting results as both ports already have MAC address X.
I'm running RHEL 6 on this machine. dmesg shows as follows:
ixgbe 0000:01:00.0: (PCI Express:5.0GT/s:Width x4) <mac_address_X>
ixgbe 0000:01:00.1: (PCI Express:5.0GT/s:Width x4) <mac_address_X>
typically that second line should be mac_address_X+1.
Any insight would be appreciated. Thanks,
