We were getting all zeros for the MAC address and we resolved that issue using by updating the NVM to the latest on the x710.  We were also having PXE issues but a lot of that went away with the new NVM.


You'll probably also want to use the latest driver too depending on the OS.  Ubuntu had an ancient version of i40e which completely stopped working once the NVM was upgraded.

Taking another shot in the dark here. Have you had anyone else report an issue that when using Intel x710 nic card that it intermittently boots via ipxe?

I'll be honest here... haven't tested our environment (I will do this tomorrow), but here is an article that explains a very similar issue http://en.community.dell.com/support-forums/servers/f/956/t/19637733.

I'll give it a go tomorrow and try printing the mac address during ipxe and will report back.

Kind Regards,

That was good timing, and the newly compiled image ended up working where we could test. However, it did not fix our issue, but we do not believe at this time the issue is related to ipxe itself; we were entertaining the idea because our networking team is being lazy.

Thanks a bunch for you help!!!

Funny you should mention that:


There are outstanding issues regarding how iPXE treats URIs, but the
ability to expand settings with any special characters URI-encoded
should work.
