The diagrams at the top of the screen can give you a quick
indication of what is going on with your network.
Inline between a Device and the Network
Caution
When operating inline with a POE-powered
device connected to NetTool, make sure that
NetTool is not plugged into the AC adapter or
into a serial device that is grounded or
damage may occur to the equipment.
If NetTool is connected inline between a device and the
network, a diagram similar to that shown in Figure 3-5 is
displayed at the top of the screen:

Figure 3-5. Diagram of an Inline Connection
This screen reflects NetTool’s connection to devices.
Note that the duplex settings and link speeds are
underscored. The underscore signifies a determined or
negotiated result while the non-underlined value signifies
the advertised value.
The diagram also indicates the duplex settings (see Table
3-2) for each device. Duplex mismatches can cause
communication between devices to be impeded.
