Does Real Time Netflow Analyzer works only with Cisco equipments?
Can i use it on a simple network with a D-Link Gigabit Wireless Router?
Realtime NetFlow Analyzer is compatible with devices that support NetFlow v1 or v5. http://knowledgebase.solarwinds.com/kb/questions/2053/
I don't believe that D-Link wireless routers have the ability to capture and send NetFlow data. Check the device documentation and/or manufacturer's website to see if your device supports NetFlow.
