Flexible NetFlow Exporter on Embedded Wireless Controller
Flexible Netflow (FnF) Exporter on Embedded Wireless Controller (EWC) is supported from Cisco IOS XE Amsterdam 17.2.1 onwards.
NetFlow is a Cisco IOS technology that provides statistics on packets flowing on the network. NetFlow is the standard for acquiring IP operational data from IP networks. NetFlow provides data to support network and security monitoring, network planning, traffic analysis, and IP accounting.
Flexible NetFlow improves on original NetFlow by adding the capability to customize the traffic analysis parameters for your specific requirements. Flexible NetFlow facilitates the creation of more complex configurations for traffic analysis and data export through the use of reusable configuration components.
FnF Exporter in EWC is supported only in the flex mode.
This feature is part of the AVC solution in EWC. For more information about AVC, refer to the Application Visibility and Control chapter.
