How to handle network aggregator traffic

    When a network aggregator sends NetFlow, the traffic originates from as little as one interface on the aggregator.  Are there any potential issues with this?  I could create custom virtual interfaces aligned with the networks where the traffic is coming from but I'm not sure how much value that will add.

    I don't believe there would be any issues with this.  If the network aggregator traffic has unique source IP addresses it will create unique devices in NFA.  If its only only 1 source IP address it will only create one device.

     

    Ideally you would want to see a unique input and output interface to represent IN and OUT data in NFA.  Without that I am not sure how much value the data would have. We would have to see what the flow data looks like in a pcap to understand how it would look in NFA.
