I have a dual port adapter, and one of the ports link light never turns on when connected to a Mellanox 100G switch using an approved Mellanox copper 100G cable.
I tried "mlxlink -d " and State says “Polling” and never changes, the other port goes immediately to “Active”.
Thanks for any feedback/ideas/…
To check if the configuration of the adapter, cabling, and switch represent a supported configuration, please check the firmware release notes for the adapter/firmware you are using. The latest firmware for the MCX516A-CCAT is v16.31.1014:

In particular, the sections regarding “mlxlink” should provide guidance on checking link parameters on the adapter and cabling.
