NetFlow V9 Format
The version 9 format is an enhancement to support flexibility within the format & different technologies such as Multicast, Internet Protocol Security (IPSec) and Multi Protocol Label Switching (MPLS).
The NFC 4.0 is compatible with the previous NF data format (NFC 3.6). NFC 4.0 shall recognize flows that contain V1, V5, V7 and V8 data formats, and make their data available to the NFC 4.0 filters and user configurable aggregation schemes.
Users can define aggregation schemes by choosing keys values supported for NF v1->9 formats.
XML/CNS Configuration and Control API
NFC 4.0 integrates with CNS using the CNS Integration Bus. This interface allows CNS applications to configure and manage CNS NetFlow Collection Engine and uses XML to format application-specific messages.
Linux Platform-Redhat v7.2
NFC 4.0 can be deployed on a Linux platform using RedHat Linux 7.2.

Cisco NetFlow Collection Engine Version 4.0
Cisco NetFlow Collection Engine Version 5.0-Fully backward compatible and it includes the following key features:
Web Based Interface
NFC 5.0 will have a web-based user interface for configuration, control, and simple reporting.
VPN PE-PE Module
A light weight version of CNS-PERFE-The NetFlow Mediator (NFM) will pull aggregation results from the NFC hosts and correlate them with the customer data obtained from the VPNSC.
DNS and Interface Name Look Up
The user will be able to configure whether or not NFC output contains IP addresses or DNS names
Max Burst Rate
Provide a thread option to record a maximum burst rate with NFC output records.
Self-Describing NFC Output
Self-describing aggregation results that contain the data type definition of all fields.
NFC 5.0 is able to output the entire Type of Service (ToS) byte; DSCP and EXP field. EXP is a 3-bit field in the MPLS header that indicates the class of service of the MPLS packet.
Top N Summary Report
Reporting allows the user to view the top X records, according to a selected field, that were used to generate a previous top X report.
