Ports
To edit or view the parameters for the SELECTED profile, select the button
called PORTS.
SINGLE mode connects one port on the LanExpert straight into a
hub, switch or network device. SINGLE mode can be plugged into
either Port 1 or Port 2. If both Ports are plugged in at the same time,
then whichever Port links first will be enabled. This will cause the
unused port to be disabled. The LEDs will indicate which Port is
linked.
INLINE mode must have both ports connected to two network
devices. INLINE mode can be used to observe the traffic flowing
between two network devices. Disconnect the cable between the
two network devices and connect one end into Port 1. Add a patch
cable from the other network device into Port 2. The LanExpert
is now between the two network devices. If a Port is not plugged in,
the corresponding LED will flash red to indicate that no cable is
plugged in.
INDEPENDENT mode must also have both Ports connected to one or
two network devices. INDEPENDENT mode can inject variable traffic
from one port onto the network while the other port listens to
investigate the effects on the network. INDEPENDENT mode can
monitor two separate network devices simultaneously. If
INDEPENDENT mode is selected then both Ports 1 and 2 will need to
be configured independently.
PORT CONFIGURATION has three modes the unit can be set to: SINGLE,
INLINE or INDEP (INDEPENDENT). See Configurations in Apendix A, page
A-1 for more details on how to connect the LANEXPERT.
