Application Statistics per Service Class from an NDE Source
Here, note again what was previously mentioned in NetFlow Collector Considerations, page 6-7. The
NAM itself cannot identify the particular application flows per service class as being IP video
surveillance flows, TelePresence flows, or VoD flows. However, if different video applications are
separated into different service classes, you may be able to determine to which video application the
flows belong. For example, in the network used for the example in Figure 6-13, only Cisco TelePresence
traffic was placed in the Real-Time Interactive service class. Therefore, you can easily identify that the
flows within Figure 6-13 represent TelePresence meetings. By selecting any one of the flows and
clicking the Details button, you can see the host IP addresses that generated the flows. Alternatively, you
can drill down into each service class to identify particular hosts responsible for the flows, based on their
IP addresses. This is done through the Diffserv Application Hosts screen, as shown in Figure 6-14.
