Mellanox Connectx3 QSFP+

[cl34980980]

Hello,
First im a total Beginner. I did build a box, installed opnsense, working fine.
For a network card i chose a connectx3. It has 2 QSFP+ Ports. I wanted to connect to my Mikrotik switch via AOC Cable. I cant get it to link up.
DAC to a second Server with Connectx3 is working. SFP+ Coper and Fiber 10gbe is working. 1g copper is working. All cabels are connecting the second server with TrueNas and connectx3 without a problem.

I got no clue how to continue. I thing it must be opnsense.

Hi,
I would suggest to try fixing the media to the right speed of the interface.
