Power over Ethernet
When an Ethernet link is established, Autotest automatically tests the port for the presence of
PoE and measures the available power by applying a minimum load. Select the PoE field in the
HOME screen and press ENTER to display the PoE screen.
Port Discovery information details
When an Ethernet link is established, Autotest automatically scans the partner port for Link
Layer Discovery Protocol (LLDP), Cisco Discovery Protocol (CDP) and Extreme Discovery
Protocol (EDP) messages when the switch is able to send discovery messages. These
messages may contain various details about the switch and the port connected, depending on
how they are configured. Select the switch / port details field in the HOME screen and press
ENTER to display the port discovery details screen.

In non-standard network
configurations it is sometimes
possible for Discovery Protocol
messages to arrive from devices
other than the directly connected
switch.
In this case, the tester attempts to
resolve which are the messages
from the correct device.
If this is not possible, the tester
reports that multiple devices have
been discovered.
