Sessions
Table 4-2, Buttons in the Capture Session Operations Window describes the operations that you can
perform from the Capture Sessions window.
Configuring Capture Sessions
You can configure up to ten capture sessions. As part of configuring a capture session, you can also
create software filters, if desired (see
Creating a Software Filter, page 4-8).
To configure a new capture session:
Step 1 Choose Capture > Packet/Capture Decode > Sessions.
Step 2 Click the Create button to set up a new capture. The NAM Traffic Analyzer displays the Configure
Capture Session window (shown in
Figure 4-3). The Capture Settings window provides a field for you
to enter a name for the capture and four status indicators described in Table 4-3.
