I'm running nTop v3.3.9 and getting many Unknown Templates collecting from an Adtran NetVanta 3305 using Netflow V9 (Only version supported by this router). There is no configurability on the Netvanta, so I'm looking for ways on the nTop side to get it to recognize the templates.

I'm willing to put effort into helping nTop recognize the Netvanta templates if someone can point me in the right direction...
