    NetFlow on Cisco 3845 router

      Is it possible to pull data from this router?


      I'm trying to ensure that we have everything set up.  Source is loopback0.  I have destination/port point to Orion server.  However, no NetFlow traffic is being detected when we pull via Orion.


       Any ideas?

          Here is my 3840 config

          interface GigabitEthernet0/1
           description OLD IP'S FROM THE 10.6.0.0 ROUTER !!!!!!!!!!!!
           ip address x.x.x.x 255.255.255.224
           ip accounting output-packets
           ip mtu 1438
           ip flow ingress
           ip flow egress
           ip route-cache flow
           ip tcp adjust-mss 1350

              The ip flow-export source is loopback0. 


              It has a IP assigned to it.  We're seeing the traffic hit the collector, but it is from an unmanaged device.  We can only add via ICMP, which negates the purpose...because we're not getting the traffic. 


              I can't add the node/interface via the IP for the loopback0 interface on SNMPv3.  Is there a way to get around this?  I talked with support and they don't have much to offer on this issue.


              I can't be the first guy to run into this problem.

              I have a 3845 and am successfully pulling data via NetFlow.  Have you insured the correct NetFlow version on your router?  Mark Stevens' reply clearly shows his configured for netflow version 5.  SolarWinds only supports version 5 in the current version (not V3).
