Hi, I connected server 10GBase-T port to switch 10GBase-T port with Cat.7 STP cable(length 1m).
Two interfaces are up at 1Gbps speed not at 10Gbps.
= Motherboard: Supermicro X10SDV-4C-TLN4F
- CPU: Intel Xeon D-1518
- LAN: 2x 1GbE via i350-AM2
2x 10GbE via SoC(x552/x557 AT?)
Supermicro | Products | Motherboards | Xeon® Boards | X10SDV-4C-TLN4F
- OS: FreeBSD 11.0-RC1, CentOS x86_64 1511
- Driver: ix-3.1.13k(FreeBSD), ix-3.1.14(CentOS)
I tried ix-3.1.14 driver installation under FreeBSD but failed to compile.
= Switch: HPE OfficeConnect 1950 24G 2SFP+ 2XGT Switch(JG960A)
- 24x 1GbE port(1-24)
- 2x 10GbE port(27, 28)

After connecting two 10GbE port of server mother board with Cat.7 STP cable, both inferfaces are up at 10Gbps.
Also connecting two switch 10GbE port with same cable, both interfaces are up at 10Gbps.
But connecting server port and switch port, all are up at 1Gbps.
It seems auto-negotiation not work well.
