Note
: The interface enp37s0f3u1u3c2 or bmc_redfish0 is recognized by the OS and may be listed
in response to such commands as ifconfig or ip addr. This interface supports BMC
communication using Redfish APIs.
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.
