We have been looking at the netflow records sent from our devices to our netflow collector and have found a couple of anomolies.
the src and dst mask is often shown as a /32 when this is not actual mask size. Also the output interface is shown as 0 when the packet would have left the device. This is happening on both version 7 netflow from 6500's (catos) and also version 5 from routers. Can anyone explain why this is happening and if it is correct.
