The following table lists the BlueField-3 supported speeds and the default networking port link type per OPN.
OPN | Data Transmission Rate | Default Protocol and Rate |
|---|---|---|

900-9D3B6-00CV-AA0 | InfiniBand: NDR200 200Gb/s Ethernet: 200GbE | Ethernet 200GbE |
| 900-9D3B6-00CC-AA0 900-9D3B6-00SC-AA0 | InfiniBand: HDR100 100Gb/s Ethernet: 100GbE | Ethernet 100GbE |
To configure the high-speed networking port mode, you can either use the mlxconfig or the UEFI tools.
UEFI can configure the DPU device before the operating system is up, while mlxconfig configures the card once the operating system is up. According to your preference, use one of the below tools:
mlxconfig
The mlxconfig tool allows users to change device configurations without burning the firmware. The configuration is also kept after reset. By default, mlxconfig shows the configurations that will be loaded in the next boot. For more information and instructions, refer to Using mlxconfig to Set IB/ETH Parameters.
UEFI
PreBoot drivers initialize the adapter device, check the port protocol type – Ethernet or InfiniBand - and bring up the port. Then it connects to a DHCP server to obtain its assigned IP address and network parameters and obtain the source location of the kernel/OS to boot from. The DHCP server instructs the PreBoot drivers to access the kernel/OS through a TFTP server, an iSCSI target, or some other service. For more information and instructions, refer to UEFI.
