If you are ,manually enabling the IPFIX on the DVS rather than having vRNI enable this during the addtion of the data source you will encounter issue's like this. We would recommend you remove the data source and re-add it allowing vRNI to enable the IPFIX function on the DVS.
Thanks. That's the behavior that I saw.
Any reason as to why manually enabling doesn't work? I would think if I'm sending flows to a netflow collector it should be getting all of those no matter what.
I'm glad I have a resolution, but it'd be cool to understand the difference between setting up a "Data source" in vRNI and just manually configuring IPFIX/Netflow.
Did it really fix your issue ?
The way we enable IPFIX should not impact the way we collect the flows..
