Setting Up NetFlow Monitoring

The broad steps towards setting up NetFlow Monitoring are as follows:

  1. Using the eG management console, manage the NetFlow-enabled device that will be generating NetFlow records, and assign an external agent to it.
  2. Deploy the eG NetFlow Collector on the same system that hosts the external agent assigned to the NetFlow device at step 1 .
  3. Open the UDP port (9996, by default) on the collector host, so that the collector can intercept and process NetFlow records; then, start the collector.
  4. Configure the eG external agent to run tests that will read the binary files created by the collector and pull relevant data on network traffic and bandwidth usage.

This chapter discusses each of these steps in detail.
