In-line Monitoring of 10 Gigabit Links
To create an in-line link on a 10 Gigabit network segment, use an external network Tap.
Figure 4 shows an LC Fiber Tap being used to send two half-duplex data streams to two 10-Gigabit Director ports. This
conguration creates a fully passive, secure in-line Tap for the 10 Gigabit network link. It is capable of transferring up
to 20 Gbps of total trafc from the full-duplex link to Director.

Figure 5 shows a 10 GigaBit Port Aggregator Tap being used to combine the trafc moving in both directions on a
full-duplex 10 Gigabit link, and send the resulting trafc stream to a single 10-Gigabit Director port. This Tap is also
fully passive and secure. The aggregated trafc from both directions on the link should be less than 10 Gbps; otherwise,
it will exceed the capacity of the Port Aggregator's monitor port and packets may be dropped. However, this should not
be a problem in most cases because network links typically operate at 30 percent or less capacity to prevent congestion.
