Classifying Network Traffic Using NBAR Features Roadmap
First Published: April 4, 2006
Last Updated: December 5, 2008
This features roadmap lists the Cisco IOS features related to Network-Based Application Recognition (NBAR) that are documented in the Cisco IOS Quality of Service Solutions Configuration Guide; the roadmap also maps the featuresto 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 that you are searching for and click on the URL in the "Where Documented" column to access the document containing that feature.
Many legacy features have been incorporated into the configuration files, and these features may not have entries in this roadmap. In addition, information in this roadmap supports other software releases or platforms. For the latest feature information and caveats, see the release notes for your platform and software release.
Feature and Release Support
Table 1 lists NBAR-related feature support for the following Cisco IOS software release trains:
Use Cisco Feature Navigator to find information about platform support and software image support. Cisco Feature Navigator enables you to determine which Cisco IOS, Catalyst OS, and Cisco IOS XE 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.

Cisco IOS Releases 12.2T, 12.3, and 12.3T
NBAR Extended Inspection for HTTP Traffic
Allows NBAR to scan TCP ports that are not well known and identify HTTP traffic that traverses these ports.
Non-intrusive Protocol Discovery enables the Catalyst 6500 series switch that is equipped with a Supervisor 32/programmable intelligent services accelerator (PISA) to perform protocol discovery in out-of-band (that is, offline) mode. In offline mode, a copy of the network traffic is used to discover the application protocols that are operating on an interface.
Integrates NBAR and Firewall Service Module (FWSM) functionality on the Catalyst 6500 series switch that is equipped with a Supervisor 32/programmable intelligent services accelerator (PISA). Provides support for Layer 2 Etherchannels and supports additional protocols.
Provides support for the DirectConnect PDLM and protocol. The DirectConnect protocol can now be recognized when using the Modular Quality of Service (QoS) Command-Line Interface (CLI) (MQC) to classify traffic.
Provides support for the Protocol Discovery MIB and stateful identification of real-time audio and video traffic (Real-time Transport Protocol Payload Classification). Also provides support for additional protocols.
The following command was modified: match protocol (NBAR).
