Ethernet port on DGX Spark is not working

I cannot get the network interface “up” on the Ethernet port of my DGX Spark computer. I confirmed the CAT6 cable and the switch port (by another DGX Spark computer), tested with point to point connections on both units, but the interface never becomes active on enP7s7.

Can you generate an nvidia-bug-report while the cable is plugged in?

Thank you for the info. Can you also run sudo ethtool enP7s7?
This will tell us if the link is active. If you see Link detected: no, try running sudo ip link set enP7s7 up and checking again with ethtool

Thank you. I executed the commands, please see below.
