Does your switch see a full MAC address for the server? Do you have an
IP conflict? Do you have a static ARP entry defined? I had some POS
Netgear NICs three or four lifetimes ago that only put 40 bits on the
wire, and I had some 3Com 3c905c-tx NICs with the same MAC address, but
I don't think either of those apply to you, in 2017.
