Figure 4-2. Link Configuration Details
On this screen, NetTool identifies the wire pair it is
connected to and reports the duplex, level, and polarity of
the signal (see Table 3-3 for descriptions of the icons
used). This information can help you troubleshoot poor
quality in a connection.
The actual and advertised speeds of the link are also
given. Monitoring this information can help you anticipate
possible performance and connectivity problems.
If the VoIP (Voice over IP) option is installed, this screen
gives you PoE (Power over Ethernet) measurements. It
displays the output power and line voltage information for
the wire pairs.
