Hello, I am trying to setup FNF on a Cisco 2921 Router. Is this Flexible Netflow Version 9 supported? I am trying to capture MPLS Interface traffic. I am working with Cisco currently, but so far only able to get traditional Netflow version 9 working.

Any help would be appreciated, thanks

Hello and thank you for your inquiry.

PRTG Currently supports two variants of Netflow: Netflow v5 and Netflow v9, but Flexible Netflow is currently not supported I'm afraid.

I'm also able to confirm that there is no ongoing/scheduled task to support this feature, as we haven't had many requests for this, we try to focus on features which would benefit the largest amount of customers possible.

Best Regards,

+1 for this feature to be added to PRTG.

This worked for me to get Flexible Netflow working with PRTG. It could prove helpful to other users until PRTG fully supports Flexible Netflow
