LAST RECEIVED NETFLOW : Never

dparmar

I have recently installed Netflow onto a Cisco Catalyst 9300 switch, but in Solarwinds I`m not receiving any netflow information.  Below is the configuration, some assistance would be most appreciated. 

thanks ........... Dinesh.

Hi @dparmar 

Need to validate if netflow packet was recieve by sw nta. You may also check the nta event for you to have a better visibility why sw nta is not displaying nta data of your switch.

Solarwind nta also do have mandatory requirement for your nta configuration. This is the most common reason why nta data is not displaying. Please refer to the link before.

You may also reach out to sw support geek to assist you why sw nta not displaying data of your switch. 

Please note that sw support geeks may ask you to use packet capture for more understanding of the issue.
