The documentation set for this product strives to use bias-free language. For the purposes of this documentation set, bias-free is defined as language that does not imply discrimination based on age, disability, gender, racial identity, ethnic identity, sexual orientation, socioeconomic status, and intersectionality. Exceptions may be present in the documentation due to language that is hardcoded in the user interfaces of the product software, language used based on RFP documentation, or language that is used by a referenced third-party product. Learn more about how Cisco is using Inclusive Language.
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 features 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 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:
•Cisco IOS Releases 12.2T, 12.3, and 12.3T
•Cisco IOS Releases 12.4 and 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, 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.

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" |
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" |
|
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" |
|
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. |

12.2(18)ZYA1 |
Non-intrusive Protocol Discovery |
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. |

12.2(18)ZYA |
NBAR—Network-Based Application Recognition |
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. |
"Classifying Network Traffic Using NBAR" "Configuring NBAR Using the MQC" The following commands were modified: ip nbar protocol-discovery, match protocol (NBAR), show ip nbar protocol-discovery. |
12.2(18)ZY2 |
NBAR—Network-Based Application Recognition (Hardware Accelerated Quality of Service (QoS) for NBAR Classification on PISA) |
Enhances NBAR functionality on the Catalyst 6500 series switch that is equipped with a Supervisor 32/programmable intelligent services accelerator (PISA). |
|

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" |
QoS: Skype Classification |
Provides support for the Skype protocol. The Skype protocol can now be recognized when using the MQC to classify traffic. Note For Cisco IOS Release 12.4(4)T, Cisco supports only Skype version 1. Other versions of Skype are supported in later Cisco IOS releases. |
"Classifying Network Traffic Using NBAR" |
|
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" |
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" |
|
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. |
