This section explains the following ways to use TAPs:

Using Electrical TAPs

Using Optical TAPs

Using TAPs Outside Your Firewall
Placing the FlowSensor Inside Your Firewall
Note:
In a network using TAPs, the FlowSensor can capture performance monitoring
data only if it is connected to an aggregating TAP that is capturing both inbound
and outbound traffic. If the FlowSensor is connected to a unidirectional TAP that
is capturing only one direction of traffic on each port, then the FlowSensor will not
capture performance monitoring data.
Using Electrical TAPs
The following illustration shows the StealthWatch FlowSensor connected to an
Ethernet electrical TAP. To achieve this configuration, connect the two TAP ports to
the FlowSensor Monitor Ports 1 and 2, as shown.
Using Optical TAPs
Two splitters are required for fiber-optic–based systems. You can place a fiber-optic
cable splitter in line with each direction of transmission and use it to repeat the optical
signal for one direction of transmission.
