The ASA and ASASM implementations of NetFlow Secure Event Logging (NSEL) provide a stateful, IP flow tracking method that exports only those records that indicate significant events in a flow.
The significant events that are tracked include flow-create, flow-teardown, and flow-denied (excluding those flows that are denied by EtherType ACLs).
