NX-OS Netflow exporting to multiple destinations

Does NX-OS support exporting of netflows to multiple destinations? I know in some versions of IOS you could export to the same port on two different IPs. This would be extremely useful for us to simultaneously evaluate different Netflow packages and compare like traffic for like.

I see where it says it, but I do not see how it can be configured. When I try to add the additional IP to the exporter it simply replaces my existing one with the new address.

Nevermind, I figured it out. I had to create a different exporter for the other destination and attach it to the monitor.

I'm trying to add another exporter to the monitor but getting:

ERROR: Flow Monitor: netflow-monitor-1 is in use. Exporters can not be added or deleted while monitor is in use.

If I disable feature netflow I lose my complete config. I there a way to stop the flow so I can add my other exporter?

I was able to add the other exporter (router 1) by deleting and re creating. Just trying to avoid re creating again...

Thanks

I try to put 3 exporters, it says "ERROR: Flow Monitor: exporters already configured."

How should I do, anyone?

 

Thank you very much.

Adding in a config for the next person that finds this.
