Classifying Network Traffic Using NBAR Features Roadmap

---

First Published: April 4, 2006

Last Updated: May 7, 2007

This roadmap lists the features related to Network-Based Application Recognition (NBAR) and maps them to the modules in which they appear.

Feature and Release Support

Table 1 lists NBAR-related feature support for the following Cisco IOS software release trains:

•Cisco IOS Release 12.2ZY

•Cisco IOS Releases 12.2T, 12.3, and 12.3T

•Cisco IOS Releases 12.4 and 12.4T

Only features that were introduced or modified in Cisco IOS Release 12.2(1) or later appear in the table. Not all features may be supported in your Cisco IOS software release.

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 Supported NBAR-Related Features 

Release	Feature Name	Feature Description	Where Documented
Cisco IOS Release 12.2ZY
12.2(18)ZY	NBAR—Network-Based Application Recognition (Hardware Accelerated NBAR)	Enables NBAR functionality on the Catalyst 6500 series switch that is equipped with a programmable intelligent services accelerator (PISA).	"Classifying Network Traffic Using NBAR" "Configuring NBAR Using the MQC"
Cisco IOS Releases 12.2T, 12.3, and 12.3T
12.3(4)T	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.	"Classifying Network Traffic Using NBAR" "Configuring NBAR Using the MQC"
	NBAR PDLM Versioning	Enables the ability to verify the Cisco IOS and NBAR Packet Description Language Module (PDLM) versions for ensuring software compatibility.	"Classifying Network Traffic Using NBAR" "Adding Application Recognition Modules"
	NBAR User-Defined Custom Application Classification	Provides the ability to identify TCP- or UDP-based applications by using a character string or value. The character string or value is used to match traffic within the packet payload.	"Classifying Network Traffic Using NBAR" "Creating a Custom Protocol"
12.2(15)T	NBAR Protocol Discovery MIBs	NBAR Protocol Discovery MIBs expand the capabilities of NBAR Protocol Discovery by providing the following new Protocol Discovery functionality through SNMP: •Enable or disable Protocol Discovery per interface. •Display Protocol Discovery statistics. •Configure and view multiple top-n tables that list protocols by bandwidth usage. •Configure thresholds based on traffic of particular NBAR-supported protocols or applications that report breaches and send notifications when these thresholds are crossed.	Network-Based Application Recognition Protocol Discovery Management Information Base
	NBAR Real-Time Transport Protocol Payload Classification	Enables stateful identification of real-time audio and video traffic.	"Classifying Network Traffic Using NBAR" "Configuring NBAR Using the MQC"
Cisco IOS Releases 12.4 and 12.4T
12.4(4)T	QoS: DirectConnect PDLM	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.	"Classifying Network Traffic Using NBAR" "Configuring NBAR Using the MQC" "Adding Application Recognition Modules"
	QoS: Skype Classification	Provides support for the Skype protocol. The Skype protocol can now be recognized when using the MQC to classify traffic. Note Currently, Cisco supports only Skype version 1. Version 2 is not yet supported.	"Classifying Network Traffic Using NBAR" "Configuring NBAR Using the MQC"
12.4(2)T	NBAR—BitTorrent PDLM	Provides support for the BitTorrent PDLM and protocol. The BitTorrent protocol can now be recognized when using the MQC to classify traffic.	"Classifying Network Traffic Using NBAR" "Configuring NBAR Using the MQC" "Adding Application Recognition Modules"
	NBAR—Citrix ICA Published Applications	Enables NBAR to classify traffic on the basis of the Citrix Independent Computing Architecture (ICA) published application name and tag number.	"Classifying Network Traffic Using NBAR" "Configuring NBAR Using the MQC"
	NBAR—Multiple Matches Per Port	Provides the ability for NBAR to distinguish between values of an attribute within the traffic stream of a particular application on a TCP or UDP port.	"Classifying Network Traffic Using NBAR" "Configuring NBAR Using the MQC" "Creating a Custom Protocol"
