Packet Capture Overview

Previous sections discussed the NAM monitoring features that provide application visibility. As you may

recall, the NAM does this by examining every packet that it receives, analyzing its layer 3, and upper-layer

packet headers and storing the results of its analysis in the MIBs for reporting. With the NAM, you can also

capture packets from any data source to view and analyze packets yourself. Packet capture, as this option is

called, enables you to capture packets from a data source and view the details of the protocol information of

each captured packet. To use this feature you must have already configured the data sources on the NAM.

Then you define the data source to use and capture settings and filters. After you collect the data, you have

the option to apply post capture decode filters to refine the presentation of the packets collected and to

download the file.

This next section covers these features and how to use the Traffic Analyzer to perform your own packet

analysis. Let’s get started.
