I would like to use breakout cables to connect multiple devices with 10G ports to a ConnectX-8 C8240 network card with qsfp to sfp breakout cables. I see that this NIC supports configuration for 8 Ethernet ports. I have run the mlxconfig commands but only see 5 ports (vs 2 originally) and have not been able to get the ports to negotiate. Help would be appreciated as I’m very new to this.
sudo mlxlink -d /dev/mst/mt4131_pciconf0.3
