Use the command in the following table to display the PHY connection information for
physical PHY M on the selected controllers. Each PHY can form one side of the physical
link in a connection with a PHY on a different device. The physical link contains four
wires that form two differential signal pairs. One differential pair transmits signals, and
the other differential pair receives signals. Both differential pairs operate
simultaneously and allow concurrent data transmission in both the receive and the

A port can contain a single PHY or can contain multiple PHYs. A narrow port contains a
single PHY, and a wide port contains multiple PHYs.
