Are you looking for a Free NetFlow Forwarder or NetFlow Duplicator? Free options are not very flexible for most customers. Our Flow Replicator can do the job and it is free for evaluators.  

Basically, it receives the UDP flow frames (NetFlow, IPFIX, sFlow, NetStream, jFlow, cflowd, etc.), changes the destination IP address while preserving the original source IP address and forwards the datagrams onto one or more destinations.  It is a very useful utility for testing multiple collectors.  It also helps customers get around the problem when the switch or router doesn’t forward NetFlow to more than one destination.  The Flow Replicator is awesome for addressing this issue.

If you are using FlowPro and need to get the flows to multiple collectors, the Flow Replicator can help with the performance of the server because you can off load the duplication to another computer.  It is pretty slick and very useful for application analysis.

I also want to mention again that Flexible NetFlow on Cisco routers allows you to configure unlimited exporters (i.e. more than just 2 destinations).  This is a great way to replicate NetFlow .   Anyway, the Flow Replicator runs as a virtual or hardware appliance and if you need help setting it up or need an appliance that can do this, we offer these services for a fee.

Michael is one of the Co-founders and the former product manager for Scrutinizer. He enjoys many outdoor winter sports and often takes videos when he is snowmobiling, ice fishing or sledding with his kids. Cold weather and lots of snow make the best winters as far as he is concerned. Prior to starting Somix and Plixer, Mike worked in technical support at Cabletron Systems, acquired his Novell CNE and then moved to the training department for a few years. While in training he finished his Masters in Computer Information Systems from Southern New Hampshire University and then left technical training to pursue a new skill set in Professional Services. In 1998 he left the 'Tron' to start Somix which later became Plixer.
