NBAR2 Custom ProtocolLast Updated: October 10, 2012
The NBAR2 Custom Protocol feature lets you create attribute profiles and attach these attribute profiles to protocols. This module provides an overview of the NBAR2 Custom Protocol feature and explains how to configure attribute profiles for custom protocols. Finding Feature InformationYour software release may not support all the features documented in this module. For the latest caveats and feature information, see Bug Search Tool and the release notes for your platform and software release. To find information about the features documented in this module, and to see a list of the releases in which each feature is supported, see the feature information table at the end of this module. Use Cisco Feature Navigator to find information about platform support and Cisco software image support. To access Cisco Feature Navigator, go to www.cisco.com/go/cfn. An account on Cisco.com is not required. Prerequisites for NBAR2 Custom ProtocolProtocol pack licensing must be enabled to configure custom protocols. Information About NBAR2 Custom ProtocolOverview of NBAR2 Custom ProtocolNetwork-Based Application Recognition (NBAR) supports the use of custom protocols to identify custom applications. Custom protocols support static port-based protocols and applications that NBAR does not support. The NBAR2 Custom Protocol feature lets you create attribute profiles for a custom protocol using the ip nbar attribute-map command. You can attach this profile to a protocol by using the ip nbar attribute-set command. An attribute profile can be modified even after you attach the profile to a protocol. You can modify (add, edit, delete) individual attributes that have already been configured. This modification does not alter the profile-protocol mapping.
