I have faced above PXE Boot Problem in HP BL460c Gen 8 & Gen 9 Blades. Because i have used Firmware version is faulty one.
We cant find out easily this problem it means .. i tried multiple times after that only find mac address is not matched with defined NIC mac address. So this is due to FW we have not update correct one.SO use and update below firmware version and it will work fine…
SPP version – SPP 2014.09 & SPP 2015.10
NIC PXE FW version – 7.10.33 & 7.12.8
