2 DHCP network interfaces from TegraA's Ethernet port in DriveWork 1.2/PX2

Hi Sir,
I saw two hdcp ip network interface (enp3s0 & eth0) for Ethernet port of TegraA, but only one eth0 in TegraB. Is it correct? Why? Thanks!

Dear garywang,

There are 3ea ethernet port on DPX2.

Please refer to DRIVE PX 2 10-Gigabit Ethernet Ownership in https://docs.nvidia.com/drive/active/5.0.10.3L/nvvib_docs/index.html#page/NVIDIA%2520DRIVE%2520Linux%2520SDK%2520Development%2520Guide%2FConfiguration%2Fnetwork_setup.html%23wwpID0E0IC0HA

Sorry I’m still not so clear on it.

I saw one 10-Gigabit for TegraA (192.168.11.66/192.168.11.116), one Gigabit Ethernet for TegraB (192.168.11.67), then two internal Ethernet port (10.0.42.28~29). Could you please give me hint for the “3ea ethernet port on DPX2”? Thanks!

Dear garywang,

Sorry for confusing you. I mean there are physically 3ea ethernet ports including harness cable on DPX2. Thanks.

Finally I got your answer!
