Chapter 1 Configuring the Network Analysis Module
Configuring the NAM
Step 1 Choose Configure > Network Analysis Module > Advanced > Classifier/App Sync. The
Classifier/App Sync Preferences window appears.
The results are displayed under the following categories:
• Conflicting classifiers/applications—You can choose one or all the WAAS classifiers/applications
for synchronization with the NAM. By default, all the classifier/applications are selected.
• NAM-only applications/application groups—Applications/application groups in the NAM are
displayed. If required, you can manually add these definitions in WAAS at the device-group or
device levels.
Step 2 To view differences in classifier definitions in WAAS and the NAM, click on the arrow next to Classifier
Definition Differences.
Step 3 Choose the WAAS classifiers that you want to synchronize with the NAM applications and provide the
required information to define the filter criteria.
Step 4 Click the Go button. The differences in the definitions are displayed.
Step 5 To view applications/application groups in the NAM, click on the arrow next to NAM-Only
Applications. Information on the applications/application groups is displayed. If required, you can
manually add these definitions in WAAS at the device-group or device levels.
Step 6 To refresh the Classifier/App Sync page, click the Refresh button.
Step 7 Click the Submit button to start the synchronization process.
Configuring a Data Source
Data sources are the source of traffic for the NAM Traffic Analyzer. Some examples are physical data
ports of the NAM where you get SPAN data, a specific router or switch that sends NetFlow to the NAM,
or a WAAS device segment that sends data to the NAM or ERSPAN and that goes to the NAM’s
management port.
A new feature in NAM 5.0 is the auto discovery of data sources, in which you can click Auto Create so
that the NAM can automatically discover the data sources. You can see details such as the IP addresses
of devices that send packets to the NAM and the time that the last NDE packet was received (in NAM
4.x, this feature was called Listening Mode).
Note If you have configured sites, you can assign data sources to that particular site. If you do assign data
sources to a site, and you also configure the data sources, the two could overlap because sites can also
be a primary “view” into data sources. If there is a mismatch between the two, you do not see any data.
Note We recommend that you configure a site using subnets instead of selecting a data source.
The following areas contain specific information about the types of data sources:
• SPAN
• ERSPAN
• VAC L
• NetFlow
