2 Enable NetFlow on most impacted routers that support NetFlow. Also, register a number of exporters to enable an efficient and scalable data collection environment. NOTE: You can disable NetFlow and unregister exporters. 3 After NetFlow has been running for a while, verify that bandwidth utilization is within expectation. This will help insure optimum performance of critical business applications. 4 Select the Top 5 Applications portlet (or add it to the page). 5 From the list of the Top 5 Applications, you'll typically see most bandwidth is being consumed by the key applications in our organization. Alternative 1 6 To ensure bandwidth is not being hijacked by unauthorized or unwanted video or music streaming applications, select the Top 5 Conversations. 7 Often the top conversation is video streaming software. 8 To answer "Where and who is running this rogue application?," drill down into the conversation to see End points involved in the conversation. This identifies the user running the streaming application. You could now go and stop (or block) this rogue application. Alternative 2 An alarm indicates port X is surpassing its threshold. If the port has become a bottleneck in the overall network bandwidth, we want to identify what applications are at cause, and who is responsible for running them. 1 Look in the Top 5 Traffic Flow Endpoints portlet. 2 From the list of the Top 5 Endpoints, you will typically see that port X is high on the list. 3 Expand the portlet and drill down into the port X endpoint to see what are the top conversations going through port X. 4 Drill down into conversations to identify any unauthorized applications. 5 Drill down further to identify users of any unauthorized applications 6 Now, go stop them! 306 Traffic Flow Analyzer - Example | Traffic Flow Analyzer
