This feature roadmap lists the Cisco IOS features documented in the Cisco IOS Flexible NetFlow Configuration Guide and maps them to the documents in which they appear. The roadmap is organized so that you can select your release train and see the features in that release. Find the feature name you are searching for and click on the URL in the "Where Documented" column to access the document containing that feature.

Feature and Release Support

Table 1 lists Flexible NetFlow feature support for the following Cisco IOS software release trains:

Cisco IOS Release 12.2SB

Cisco IOS Release 12.2SR

Cisco IOS Release 12.4T

Use Cisco Feature Navigator to find information about platform support and software image support. Cisco Feature Navigator enables you to determine which Cisco IOS and Catalyst OS software images support a specific software release, feature set, or platform. To access Cisco Feature Navigator, go to http://www.cisco.com/go/cfn. An account on Cisco.com is not required.


Note Table 1 lists only the Cisco IOS software release that introduced support for a given feature in a given Cisco IOS software release train. Unless noted otherwise, subsequent releases of that Cisco IOS software release train also support that feature.


Table 1 lists the most recent release of each software train first and the features in alphabetical order within the release.
