Why each option
NetFlow provides comprehensive insights into IP traffic, detailing who, what, where, when, and how, by accounting for both transit and locally destined/originated traffic, and includes subinterface information in its records.
By default, traditional NetFlow records IP traffic flows unidirectionally; bidirectional flow monitoring is an enhancement primarily supported by Flexible NetFlow.
NetFlow records provide granular details like source/destination IP addresses, ports, protocols, timestamps, and interfaces, which collectively answer questions about traffic origin, destination, type, time, and path.
NetFlow is configured on router interfaces and captures all IP traffic passing through them, including traffic that traverses the router (transit traffic) and traffic that is locally destined for or originated from the router itself.
NetFlow records include details about the input and output interfaces, which inherently supports the reporting of traffic flow through specific subinterfaces if they are part of the flow path.
