NBAR Protocol Pack
The NBAR Protocol Pack feature provides an easy way to load a protocol pack, which is a single compressed file that contains multiple Protocol Description Language (PDL) files and a manifest file. Before this feature was introduced, PDLs had to be loaded separately. With NBAR Protocol pack, a set of required protocols can be loaded, which helps network-based application recognition (NBAR) to recognize additional protocols for classification on your network.
The protocol pack manifest file contains a description of the protocol pack. Packet Description Language Modules (PDLMs) are used to add support for a protocol that is currently not available as part of the Cisco IOS software.

Information About the NBAR Protocol Pack
Protocol Pack Overview
Application recognition modules (also known as PDLMs) can be used to extend the functionality of NBAR by enabling NBAR to recognize additional protocols on your network. A PDLM is used to add support for a protocol that is currently not available as part of the Cisco IOS software. A PDLM extends the list of protocols that NBAR can recognize.
A protocol pack is a single compressed file that contains multiple PDL files and a manifest file. Your organization determines the contents of the protocol pack. Protocol packs allow you to load a set of protocols together rather than load them separately.
Protocol packs provide the following features:
- They are easy to load.
- They are easy to upgrade to a higher version protocol pack or revert to a lower version protocol pack.
- They provide only the required set of protocols.
Cisco provides a specific identity number for the organization (also known as "publisher") that creates the protocol packs and uses Cisco tools and processes to create new protocol packs. The organization that creates the protocol pack owns the pack.
The Default Protocol Pack (DPP) is provided as the base protocol pack version with the Cisco IOS image in the router.

Configuration Examples for the NBAR Protocol Pack
Example: Loading the NBAR Protocol Pack
The following example shows how to load an NBAR protocol pack named defProtoPack from the harddisk:
Router> enable Router# configure terminal Router(config)# ip nbar protocol-pack harddisk:defProtoPack Router(config)# exit
The following example shows how to load a default NBAR protocol pack:
Router> enable Router# configure terminal Router(config)# default ip nbar protocol-pack Router(config)# exit
The following example shows how to load a protocol pack of a lower version using the force keyword:
Router> enable Router# configure terminal Router(config)# ip nbar protocol-pack harddisk:olddefProtoPack force Router(config)# exit
