Example: Exporting Flows to Multiple Collectors
This example describes how to configure RUGGEDCOM ROX II to forward NetFlow data to two NetFlow collectors.
In the following topology, the NetFlow exporter (RUGGEDCOM ROX II) is collecting data on packets traversing
two interfaces. Packets sharing the same characteristics (i.e. source, destination, port, etc.) are placed into flows.
When each flow is either deemed inactive, has exceeded the active timer, or is flagged as terminated, the exporter
forwards the flow to the specified collectors.
IMPORTANT!
The values shown are specific to the provided topology. Actual values can vary based on the user's
configuration.
