4.6 Passive testing
NOTE: Passive testing is a purchasable option. Please contact Spirent for more information.
Passive testing allows non-intrusive testing on a bridged Ethernet link. The following sections describe
passive testing and bridge setup in more detail.
4.6.1 Unit setup for passive testing
Because the two 10/100/1G ports are joined internally by a functional Ethernet switch, the unit is
inherently capable of bridging an Ethernet link when placed in the middle. With a bridged link, the unit
can passively monitor traffic between the ports (that is, the traffic flowing across the “bridge”), such as
during a passive measurement of video quality. The ports are always active; therefore, the bridge
capability is always active, with the monitoring feature activated when a passive test is run.
With a passive test, the unit does not send any traffic on the link, nor does it interfere with any traffic
passing through the link. However, an active link will be naturally disrupted when the unit is physically
placed in the middle. For a passive test to run, it is required that the desired traffic is activated or restored
between the bridged endpoints before the testing begins. Using the example of passive video testing,
consider the following typical setup:
