I've been trying to test Netflow Trqffic Analyser with mixed results. If I use any router with physical interfaces, the product works well. However, I've been trying to use the product on a Cisco Catalyst 6500 with virtual interfaces. I continuously get the "receiving a NetFlow data stream from an unmanaged interface on X.X.X.X". I do not need or want to add every interface from the device. No matter which IP address I use to manage the device, I still get the same error.
