NVIDIA ConnectX-5 Ethernet Adapter Cards for OCP Spec 2.0 User Manual

Finding the MAC on the Adapter Card

Each NVIDIA adapter card has a different identifier printed on the label: serial number and the card MAC for the Ethernet protocol and the card GUID for the InfiniBand protocol. VPI cards have both a GUID and a MAC (derived from the GUID).
