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.

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 ?

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

Giuseppe

Hello,

 

you might want to globally configure:

 

ip flow export-version 9

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

Giuseppe

 

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.
