Hi team,

I am using MCX75310AAC-NEAT hardware, in Precision 3680 PC with Ubuntu 22.04 OS.
Does this hardware support 200G speed? Other lower speed rates? or is it fixed to 400G?
~$ sudo mlxlink -d /dev/mst/mt4129_pciconf0 -p 1| grep “Enabled Link Speed “
Enabled Link Speed : 0x000000f1 (NDR,HDR,EDR,FDR,SDR)

Thanks in advance.

Is it possible to configure to NDR200?
I tried to configure but it showed , NDR200 invalid speed configuration.

Do I need to update firmware for the same? As I used latest firmware.

$ sudo mlxlink -d /dev/mst/mt4129_pciconf0 -p 1 --speeds NDR200

Let me know what changes to be made to work for NDR200

as per the firmware compatible “ Firmware Compatible Products - NVIDIA Docs ” shows NDR200 is supported.

Could you please let me know why the NDR200 is not able to set using mlxlink set speed?
