Hello there,

To which port are you sending the sFLOW traffic? PRTG's sFlow sensors use port 6343 by default(Can be modified within the sensor's settings).

In order to find out if proper and compatible Sflow packets are arriving at the PRTG host (or host of the Remote Probe), please use our Sflow Tester: Paessler sFlow Tester

You'll need to either use a different port in the sFlow Tester or pause any sensors in which may be using that port in PRTG before using the tester.

Please share a screen-shot or the logs from the Sflow Tester.

Best Regards,

Hi Nguyen,
thank you for your reply.

Please note that we're not able to provide device-specific set-up instructions. Once you've got the standard Netflow sensor working (and this mostly refers to the device's configuration, outside PRTG) and want to use custom rules to capture ingress or egress traffic, please refer to:

The following KB-Post also addresses the Ingress x Egress difference:
