    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)?
