Table 1 Supported Cisco IOS NetFlow Features 

Release	Feature Name	Feature Description	Where Documented
Cisco IOS Release 12.0S
12.0(26)S12.0(25)S 12.0(24)S	MPLS-aware NetFlow	Multiprotocol Label Switching (MPLS)-aware NetFlow is an extension of the NetFlow accounting feature that provides highly granular traffic statistics for Cisco routers. MPLS-aware NetFlow collects statistics on a per-flow basis just as NetFlow does. MPLS-aware NetFlow uses the NetFlow Version 9 export format.	"Configuring MPLS-aware NetFlow"
12.0(26)S	NetFlow BGP Next Hop Support	The NetFlow Border Gateway Protocol (BGP) Next Hop Support feature lets you measure network traffic on a per BGP next hop basis. Without the NetFlow BGP Next Hop Support feature, NetFlow exports only IP next hop information (which provides data on only the next router); this feature adds BGP next hop information to the data export.	"Configuring NetFlow BGP Next Hop Support for Accounting and Analysis"
12.0(26)S	Random Sampled NetFlow	Random Sampled NetFlow provides NetFlow data for a subset of traffic in a Cisco router by processing only one randomly selected packet out of n sequential packets (n is a user-configurable parameter). Packets are sampled as they arrive (before any NetFlow cache entries are made for those packets). Statistical traffic sampling substantially reduces consumption of router resources (especially CPU resources) while providing valuable NetFlow data. The main uses of Random Sampled NetFlow are traffic engineering, capacity planning, and applications where full NetFlow is not needed for an accurate view of network traffic.	"Using NetFlow Filtering or Sampling to Select the Network Traffic to Track"
12.0(24)S	NetFlow v9 Export Format	NetFlow Version 9 is a flexible and extensible format, which provides the versatility needed to support new fields and record types. This format accommodates new NetFlow-supported technologies such as Multicast, Multiprotocol Label Switching (MPLS), and Border Gateway Protocol (BGP) next hop. The distinguishing feature of the NetFlow Version 9 format is that it is template based.	"Configuring NetFlow and NetFlow Data Export"
12.0(22)S	NetFlow Subinterface Support	The NetFlow Subinterface Support feature provides the ability to enable NetFlow on a per-subinterface basis.	"Configuring NetFlow and NetFlow Data Export"
12.0(19)S	NetFlow Multiple Export Destinations	The NetFlow Multiple Export Destinations feature enables configuration of multiple destinations of the NetFlow data.	"Configuring NetFlow and NetFlow Data Export"
12.0(15)S	NetFlow ToS-Based Router Aggregation	The NetFlow ToS-Based Router Aggregation feature enables you to limit router-based type of service (ToS) aggregation of NetFlow export data. The aggregation of export data provides a summarized NetFlow export data that can be exported to a collection device. The result is lower bandwidth requirements for NetFlow export data and reduced platform requirements for NetFlow data collection devices.	"Configuring NetFlow Aggregation Caches"
12.0(11)S	NetFlow Minimum Prefix Mask for Router-Based Aggregation	The NetFlow Minimum Prefix Mask for Router-Based Aggregation feature allows you to set a minimum mask size for prefix aggregation, destination-prefix aggregation, and source-prefix aggregation schemes.	"Configuring NetFlow Aggregation Caches"
Cisco IOS Release 12.2S
12.2(25)S	NetFlow Input Filters	The NetFlow Input Filters feature provides NetFlow data for a specific subset of traffic by letting you create filters to select flows for NetFlow processing. For example, you can select flows from a specific group of hosts. This feature also lets you select various sampling rates for selected flows. The NetFlow Input Filters feature is used, for example, for class-based traffic analysis and monitoring on-network or off-network traffic.	"Using NetFlow Filtering or Sampling to Select the Network Traffic to Track"
12.2(25)S	NetFlow MIB	The NetFlow MIB feature provides MIB objects to allow you to monitor flow cache information, the current NetFlow configuration, and statistics.	"Configuring SNMP and the NetFlow MIB to Monitor NetFlow Data"
12.2(25)S	NetFlow MIB and Top Talkers	The NetFlow MIB and Top Talkers feature uses NetFlow functionality to obtain information regarding heaviest traffic patterns and most-used applications in the network.	"Configuring NetFlow Top Talkers using Cisco IOS CLI Commands or SNMP Commands"
12.2(18)S	NetFlow BGP Next Hop Support	The NetFlow Border Gateway Protocol (BGP) Next Hop Support feature lets you measure network traffic on a per BGP next hop basis. Without the NetFlow BGP Next Hop Support feature, NetFlow exports only IP next hop information (which provides data on only the next router); this feature adds BGP next hop information to the data export.	"Configuring NetFlow BGP Next Hop Support for Accounting and Analysis"
12.2(18)S	NetFlow Multicast Support	The NetFlow Multicast Support feature lets you capture multicast-specific data (both packets and bytes) for multicast flows. For example, you can capture the packet-replication factor for a specific flow as well as for each outgoing stream. This feature provides complete end-to-end usage information about network traffic for a complete multicast traffic billing solution.	"Configuring NetFlow Multicast Accounting"
12.2(18)S	NetFlow v9 Export Format	NetFlow Version 9 is a flexible and extensible format, which provides the versatility needed to support new fields and record types. This format accommodates new NetFlow-supported technologies such as Multicast, Multiprotocol Label Switching (MPLS), and Border Gateway Protocol (BGP) next hop. The distinguishing feature of the NetFlow Version 9 format is that it is template based.	"Configuring NetFlow and NetFlow Data Export"

Cisco IOS Releases 12.2T, 12.3, and 12.3T
12.3(14)T	NetFlow Layer 2 and Security Monitoring Exports	The NetFlow Layer 2 and Security Monitoring Exports feature adds the ability for NetFlow to capture the values from several fields in Layer 3 IP traffic and Layer 2 LAN traffic to obtain information that can be used to classify and identify network traffic. This information can be used to help identify network attacks and their origin.	"NetFlow Layer 2 and Security Monitoring Exports"
12.3(11)T	Egress NetFlow Accounting	The Egress NetFlow Accounting feature allows NetFlow statistics to be gathered on egress traffic that is exiting the router. Previous versions of NetFlow allowed statistics to be gathered only on ingress traffic entering the router.	"Configuring NetFlow and NetFlow Data Export"
