    Nexus7010 - NetFlow Receiver Service xxxx is receiving a NetFlow data stream from an unmanaged interface

      We have recently upgraded our Core network infrastructure to Cisco Nexus 7010 Switches.  Since the upgrade I am unable to get Orion Netflow to see the data, when I look at the Netflow Sources it shows the two switches but they have never seen any netflow data.

      The event summary shows: -

      NetFlow Receiver Service [xxxxx] is receiving a NetFlow data stream from an unmanaged interface on xxxxxxxxx. The NetFlow data stream will be discarded. Please use Orion Node Management to manage interface '#81' in order to process this NetFlow data stream, or just use Edit this device.

      All interfaces on the Nexus are being monitored by NPM with a read/write community string.

      The switch config is: -

      ip route-cache flow infer-fields

      ip flow ingress infer-fields

      ip flow-cache timeout active 1

      ip flow-export source Vlan1

      ip flow-export version 5

      ip flow-export destination xxxxxxxxx 2055

      I know the Orion server is constantly seeing streams from the IP's because I have capture port 2055 on Wireshark and I am seeing a constant stream of data.

      Any idea's?
