RTP Filter

When the NAM Traffic Analyzer is initially started, RTP stream traffic will automatically start being monitored. The NAM enables you to monitor all RTP stream traffic among all SPANed traffic, without having to know the signaling traffic used in negotiating the RTP channels. RTP Stream Monitoring is enabled by default under Setup > Monitoring > RTP Filter. To disable it, uncheck the “Enable RTP Stream Monitoring” check box and click the Submit button to apply the change.

To create an RTP filter:

Step 1 Choose Setup > Monitoring > RTP Filter.

Step 2 Click the Create button.

Step 3 From the drop-down menu, choose the protocol (IP or IPv6).

Step 4 Enter the Source Address, Source Mask, Destination Address, and Destination Mask. Step 5 Click OK.

URL

The URL collection listens to traffic on TCP port 80 of a selected datasource and collects URLs. Any protocol which has its master port set to TCP port 80 can be used for URL collections. Only one collection on a single datasource can be enabled at a time.

A URL, for example: http://host.domain.com/intro?id=123, consists of a host part (host.domain.com), a path part (intro), and an arguments part (?id=123).

The collection can be configured to collect all parts or it can configured to collect only some of the parts and ignore others.

This section contains the following procedures:

•Enabling a URL Collection

•Changing a URL Collection
