[j-nsp] netflow sampling problem in 10.2

[Chris Tracy]

Hi Matjaž,

Are you doing RE-based sampling, or using an MS-DPC?  Can you post a sanitized version of your config?  You might want to look at some of the previous posts to the list on this topic, such as:

This thread was specific to NetFlow v9 using an MS-DPC though...

We are sampling IPv4 packets ingress on all interfaces. Firewall filters work fine. The corresponding firewall filter terms still count bytes and packets, but no samples are seen.
