Note: The enp37s0f3u1u3c2 interface or bmc_redfish0 is recognized by the OS and may be
listed in response to such commands as ifconfig or ip addr. This interface is reserved for future
support of BMC communication using Redfish APIs and is not available for configuration.
Note: The Optional column lists the port designations after reconfiguring the default InfiniBand
ports to Ethernet.
When switching from the default Ethernet to InfiniBand, the InfiniBand port designations will
vary depending on changes made to the other ports.
1.2.2. Supported Network Cables and Adaptors
The DGX A100 system is not shipped with network cables or adaptors. You will need to
purchase supported cables or adaptors for your network.
The ConnectX-6 or ConnectX-7 firmware determines which cables and adaptors are
supported. For a list of cables and adaptors compatible with the NVIDIA ConnectX cards
