4. At the Hardware View, verify the location of the port to be tested.
When the mouse pointer is passed over the graphical port on the
front view of the switch, the port highlights with a blue border
and an pop-up displays Switch Port.

perform the loopback test are reconnected properly. A change
to the cable configuration disrupts zone operation and may
incorrectly include or exclude a device from a zone.
