Netflow configuration on Cisco Nexus 1000v with iMC NTA 7.0

[battagfe]

Hi all,

I've problems to collect data traffic from a Nexus 1000v (virtual) switch via netflow and iMC NTA.

After reading the documentation I inserted on the Nexus 100v the following configuration, but iMC doesn't collect any data. However I have seen, with Wireshark, packets from the Nexus 100v to NTA arrive correctly.

Vethernet1 is the interface which is connected to a server that produces traffic.

Does anyone have:

- A suggestion about it, how iMC don't ever shows me traffic?

- Can tell me if it's appropriate to collect the traffic directly from the Nexus 1000v or is better to use a probe to capture traffic between virtual machines (I need an extra license)?

Did you configured NTA to listen on 9996 (NTA>Settings>ServerManagement>Listen ports)?
