NOTE

All zeros are displayed in the Last MAC addr field if the Management Module never recognized the device on the port.

For example, the device plugged into the port always had wrong polarity cabling between it and the hub.

Port: Displays the port number in the hub where the wrong polarity device was found.

Last MAC addr: Displays the hardware address of the most recent device that sent data on that port.

Problem: Displays what the problem is. In this screen, wrong polarity cabling between the device and the hub. Wrong polarity cabling is when the TX+ and TX- pairs or RX+ and RX- of a UTP cable are reversed. This is usually caused by making your own cables. If a wrong polarity cable is detected, try using a different cable.
