NetFlow Configurator 1.0
Remotely and quickly configuring NetFlow v5 via SNMP on supported Cisco devices. more>> Meet the newest free tool in the SolarWinds portfolio: NetFlow Configurator! NetFlow traffic analysis has become an increasingly important factor when it comes to managing your network and keeping an eye on bandwidth utilization. So we designed a free tool that makes it easier than ever before to get started with Cisco NetFlow!
SolarWinds NetFlow Configurator is an easy-to-use tool for remotely and quickly configuring NetFlow v5 via SNMP on supported Cisco devices. NetFlow Configurator also facilitates setting up collectors for Cisco NetFlow data, specifying the ports on which the collectors are listening, and enabling monitoring of inbound and outbound (ingress/egress) traffic data per interface.
NetFlow Configurator is just one of several SolarWinds applications that can aid you in performing NetFlow traffic analysis. Check out these other great NetFlow tools with FREE 30-day evaluations!
SolarWinds NetFlow Real-time Tool, which is included in our award-winning Engineers Toolset, is a real-time capture and analysis tool that stores up to one hour of Cisco NetFlow data on a single router interface. It displays interface inbound and outbound traffic separately for granular analysis and troubleshooting.
Orion NetFlow Traffic Analyzer enables you to capture continuous streams of network traffic across multiple router interfaces and convert those raw numbers into easy-to-interpret charts and tables that reveal exactly how the corporate network is being used, by whom and for what purpose enabling you to shut down the bandwidth hogs.<<less

Paessler Netflow Tester 2.0
Paessler Netflow Tester is a free program that simply dumps the data of all Netflow packets that a computer receives from a Cisco router. This can be useful when debugging bandwidth monitoring configurations based on Ciscos Netflow protocol. more>>
Paessler Netflow Tester 2.0 is used for dumping the data of all Netflow packets that a computer receives from a Cisco router. This can be useful when debugging bandwidth monitoring configurations based on Ciscos Netflow protocol. First the Netflow protocol must be enabled and configured on the router. Then the router must be given the IP address of the computer running Netflow tester so that the UDP data packets with Netflow data are sent to that computer.
Major Features: Just follow these simple instructions:
- Download Paessler Netflow Tester and then start netflowtest.exe
- Enter the IP and port number that you have configured as netflow packet target in your Cisco Router. Usually selecting "any IP" should work, in some cases the IP must be explicitly selected.
- Enable "Start Netflow Collector".
- You should now see a line in the logfile for each packet the computer receives. Each line shows the time, netflow version, number of flows and the IP of a packet (note: You need netflow version 5 for PRTG Traffic Grapher!)
- Enable "Show Flow Data" to also show the corresponding flow data.
- If you do not see any activity then the system does not receive any netflow data (e.g. due to misconfiguration of the router or a firewall blocking the packets, etc.)
Requirements: Windows 2000/XP/2003/Vista/2008

Real-time NetFlow Analyzer 9.2.1.23
Capture, analyze and track network traffic in real time. more>> Capture, analyze and track network traffic in real time.
Do you know how your network is being used? Can you see if your bandwidth is being used for good or evil? What about identifying those traffic spikes caused by marketing forwarding around the latest YouTube video or the occasional lunch-hour Warcraft tournament over in support? Did you know that you already have the resources on your network to answer all of these questions and more? All you have to do is use NetFlow!
Never fear we have the key weve developed a free tool that shows you exactly whats on your network. SolarWinds newest free tool, Real-time NetFlow Analyzer, unlocks the power of NetFlow on your network, empowering you to shutdown the bandwidth hogs and ensure peak performance of your mission-critical network applications.
If you are new to NetFlow, youre going to love this powerful protocol developed by Cisco Systems to collect IP traffic information on routers. And, if you havent already, it is easy to turn on flows on your existing Cisco routers to get deep visibility into whats happening on your network. We even have a free tool NetFlow Configurator to help you remotely configure NetFlow v5 via SNMP on supported Cisco devices, so you can get started immediately.
Once youve turned on NetFlow, Real-time NetFlow Analyzer captures and analyzes this data in real time to show you exactly what types of traffic are on your network, where that traffic is coming from, and where it is going. Finally, you can take the guesswork out of diagnosing network traffic spikes and troubleshooting bandwidth issues with this free NetFlow monitoring tool!
Real-time NetFlow Analyzer displays inbound and outbound traffic separately for granular analysis that makes problem diagnosis quick and easy. Even better, you can view the historical NetFlow data broken out by application, conversation, domain, endpoint, and protocol. That way you know exactly how your bandwidth is being used and by whom.
Main features:
- Investigate, troubleshoot, and quickly remediate network slowdowns
- Easily identify which users, devices, and applications are consuming the most bandwidth
- Isolate inbound and outbound traffic by conversation, application, domain, endpoint, and protocol
- Personalize NetFlow data displays to view traffic by specified time periods and by traffic type
- Customize refresh rates and display units for NetFlow traffic
System requirements:
- Pentium-like processor
- 8 MB HDD
- 32 MB RAM
