To Connect to the System Under Test
2 Using the Analyzer
There are three system connection options:
• intrusive
• non-intrusive
• diagnostic
Intrusive System Connection
When you install or remove an intrusive system connection, it affects the
traffic on the link to which the analyzer is connected. Either you need to
take the link offline to make the connection, or you need to interrupt
traffic.
The test connections available for intrusive system are
• network element
• remote loopback
• in-line
The interface configuration options for an intrusive connection are
• full duplex
• receive loopback
• regenerator
• loop through
Network Element Test Connection
You can use the analyzer to transmit test traffic that passes through the
network element, then returns to the analyzer for analysis and
comparison with the originally transmitted test traffic.
A typical application for this type of connection is installing and
troubleshooting a single network element, for example, checking whether
the network element is performing according to its specifications. Use this
connection to monitor, capture, and transmit traffic.
