This article provides brief information on the issue when NTA receives high volume of traffic from the SolarWinds server to devices.
NTA: Unknown traffic was received
NTA version 3.11
The NTA System just listens on port 2055, the NTA server does not send request or generates traffic from the NTA server to your NTA configured devices.
The message NTA: Unknown traffic was received is telling you that NetFlow Receiver Service is receiving a NetFlow data stream from an unmanaged device. The NetFlow data stream from that device will be discarded. Please use Orion Node management to manage this IP address in order to process this NetFlow data stream, or just use Manage this device.
