[j-nsp] netflow sampling problem in 10.2

Hi there,

we've recently upgraded our MX routers to 10.2R3.10 (from 9.6). After that, netflow sampling based on firewall filters does not export any packets, not even to a local file. Total silence! 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.

Have some of you run into similar problems with sampled netflow on 10.2? Release notes do not mention anything similar.

Kind regards,
	Matjaž
