Chapter 4 Capturing and Decoding Packet Data
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.
Packets Number of packets
State The current status of the capture:
• Running—Packet capture is in progress
• Stopped—Packet capture is stopped. Captured packets remain in
buffer, but no new packets are captured
• Full (Cisco 2200 Series appliances only)—The memory or file is full,
and no new packets will be captured.
