Hello,

I have a ConnectX-6 100G network card (MCX653106A-ECA) and a QSFP+ 40GBASE-SR4 connected to it. My question is how to configure the mellanox card so that it recognizes breakout 4x10, provided that only 1 link out of 4 will be used.

Device Type: ConnectX-6
Part Number: MCX653106A-ECA_Ax
Version FW: 20.43.2566

Hi ,

Please refer to the below page

The configuration is done on the switch side , from the Network adapter side there is auto neg enabled so it will detect the speed set by the switch .

Thanks
Samer
