I am trying to setup Netflow to work with a Adtran NetVanta 1238 PoE switch so the data will work with NTA
NetFlow feature is available on AOS data products running firmware version 16.1 or later. But I am not sure if Adtran 1238POE supports NetFlow export. You can verify if it does from this link:
AOS Feature Matrix - Product Feature Matrix | ADTRAN Support Community
If it does, you need to enable NetFlow on the Adtran and have it send flow data to your SolarWinds NTA. Adtran terms their NetFlow as Integrated Traffic Monitoring and you can find some config information in the following links.
