Netfow v9 - showing 75% other traffic




I have issue with resolving an issue with data on netflow v9 sensors. I am not sure whether the issue is with PRTG configuration or something on my side.

I tested the netflow with the tester v9 and getting all 256 templates and data are arriving correctly also confirmed by wireshark around templates as well. however, within prtg I am getting about 76% of all traffic as other. I understand that I have number of channels undefined, but when I look turn the stream data log on for other traffic 98% of the other traffic is IPs Port 0, only MAC's are correct.

the sensor it self is setup with default values and no filters.

Any advise?

To allow us a better overview of what is going on, please send us the following screenshots of the affected sensor (out of the PRTG AJAX Webinterface):
- the "Overview" tab,
- the "Log" tab,
- the "Settings" tab (multiple screenshots if necessary to cover all options).

Please make sure the screenshots show the entire user interface, and aren't cropped.

Best regards.
