Hi everyone, I need to enable Flexible Netflow for interface Gi0/0/0.1510 (encapsulation dot1Q), my SolarWinds no picture data, because Netflow sumarizes routed traffic. When apply Flexible Netflow to interface Gi0/0/0.1510 with commands "show flow monitor <name> cache format table" collect data, but my SolarWinds no data. Some one has same scenario.

Hello,
what device is this configured on ? Can you post the running config ?

In addition to other comment,
Does your solarwinds working with netflow devices ? is this only First device you configuring to export data to Solarwinds ?
Is Solarwinds IP reachable to device you trying to export Data ?
Can you post the relavant configuration as requested, and alos as you mentioned that you see the data on device exported (not seeing on solarwinds ) - in that path do you have any firewall ? also rung any wireshark see is the packet reaching from Device to solarwinds ?

Hi @balaji.bandi, on router see traffic with Exporter IPs and I have many devices in Solar but it is not picture data.

Hello @nostosalgos ,
you have to provide more details and info in order to get help.
post
show version
posr all netflow related configuration
and also what is the source interface used for exporting Netflow data ?
Some platforms cannot use the management interface to export Netflow data, so the choice of the source interface for sending neflow accounting packets is important.
Hope to help

Hello,
you might want to globally configure:
ip flow export-version 9
09-24-2021 11:29 AM
Hello @nostosalgos ,
interface gi0/0/0.1510 is at the same time the interface you would like to monitor with netflow and the source for sending netflow account packets.
You would see also those accounting flows exported.
If you want to test the feature apply the ip flow FLOW_MONITOR-SOL to other interfaces on the router and remove it from the interface used for exporiting netflow accounting data.
However, your configuration looks like correct try to apply the global command suggested by @Georg Pauwen about Netflow version.
Hope to help

I never using mixing monitor in one (exports in) - i always use different IN and OUT flow Monitors
also worth adding below line for your monitor
cache timeout active 60
Can you post :
show flow monitor FLOW-MONITOR-SOLAR cache
@i do not believe it required netflow version, some version of code now show, but can be view in show run all.
