Netflow is not working

VishnuPS — Tue, 13 Jul 2021 16:31:22 GMT

Dear Team,

Netflow hasn't been working. When we enable and disable Netflow on an interface our SolarWinds server receives a tiny bit of Netflow traffic but then stops again. Netflow traffic is however leaving the firewall and destines for the SolarWinds server.

We have not found any drops in the PCAP.

We found some error in the global counters, But we not sure it's related to Netflow.

flow_fwd_l3_mcast_drop 170 2 drop flow forwar
d Packets dropped: no route for IP multicast
flow_fwd_l3_noarp 190 3 drop flow forwar
d Packets dropped: no ARP

Regards,

Vishnu PS

Hello,

What do your unified logs show for the traffic? What about the Service Route Configuration? Some models of PAN you cannot use the management interface as the source of the Netflow traffic.
