If there is a Layer 7 fingerprint and a Layer 4 mapping for a particular...

If the Layer 4 mapping override policy is not "Unknown/Unclassified", the Layer 4 mapping applies to flows not passing a Sensor or other application fingerprinting device as well as to flows not matching any defined Layer 7 fingerprint

If the Layer 4 mapping override policy is "Always", then the Layer 7 fingerprint will never be used for flows matching both criteria

If the Layer 4 mapping override policy is "Unclassified", the Layer 4 mapping only applies to flows not passing a Sensor or other application fingerprinting device

If the Layer 4 mapping override policy is "Unknown/Unclassified", the Layer 4 mapping applies to flows not passing a Sensor or other application fingerprinting device as well as to flows not matching any defined Layer 7 fingerprint

Care must be taken when defining reports and policies to reflect overlapping definitions and the Layer 4 override policy

The traffic Expression "app L7_fingerprint or app L4_mapping" will catch all traffic flows for the application data in a report
