8.4 Port Configuration
8.4.1 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 8.4.2, “Port Protocol Con-
figuration”, on page 38.
8.4.2 Port Protocol Configuration
Step 1. Display the Device Manager and expand “System devices”.
Step 2. Right-click on the Mellanox ConnectX Ethernet network adapter and left-click Properties.
Select the Port Protocol tab from the Properties window.
The “Port Protocol” tab is displayed only if the NIC is a VPI (IB and ETH).
