Hi Maru,

Actually in VMWare case, we will be able to see the physical NIC port address from VCenter(View Network Adapters in Configuration tab of the physical cluster node). I'm not sure how I can get the same information in OVS case...

When you mentioned 'it can obviously be discovered manually', what exactly did you refer to?

Thanks very much,

YuLing

It is not possible to retrieve the physical mac port as you desire via Quantum's API.  The mapping of physical NIC to virtual NIC is plugin-specific and not exposed, though it can obviously be discovered manually.

What use-case are you thinking of that requires discovery of the physical mac that is transiting traffic for a given VM?

So, another question is whether I can get the physical NIC port MAC from Openstack Quantum? The plugin configured in my environment is OVS plugin.

Port details would also show the MAC address of the port(something like fa:16:3e:97:1f:b7). Is this MAC address the physical MAC address of the port on the NIC card? If not, what MAC address is it?
