Using the Analyzer
To Connect to the System Under Test
2-6
When using an in-line test connection, configure the affected port(s) for a
full duplex, regenerator, or loopthrough interface configuration (according
to the type of interface pod installed).
The disadvantage of the in-line test connection is that you need to break
the link to install and remove the connection. Therefore, for networks that
are already running live traffic, it is better to use a non-intrusive system
connection, such as passive and T-piece test connections.
Non-Intrusive System Connection
A non-intrusive system connection does not affect the traffic on the link to
which the analyzer is connected. A non-intrusive system connection is
most useful because you can run in-service tests without interfering with
the live system traffic.
There are two test connections available for the non-intrusive system
connection:
•
passive
•
T-piece
The analyzer interface configuration options for a non-intrusive system
connection are full duplex and receive loopback.
