3.4 Port Configuration
After WinOF OFED VPI installation, it is possible to modify the network protocol that runs on
each port of VPI adapter cards. Each port can be set to run as InfiniBand, Ethernet or Auto Sens-
ing.
3.4.1 Auto Sensing
Auto Sensing enables the NIC to automatically sense the link type (InfiniBand or Ethernet) based
on the cable connected to the port and load the appropriate driver stack (InfiniBand or Ethernet).
Auto Sensing is performed only when rebooting the machine or after disabling/enabling the
mlx4_bus interface from the Device Manager. Hence, if you replace cables during the runtime,
the NIC will not perform Auto Sensing.
For further information on how to configure it, please refer to Section 3.4.2, “Port Protocol Con-
figuration”, on page 19.
