Cisco Systems, Inc. has released a new feature, the NBAR Protocol Pack, which provides an easy way to load multiple Protocol Description Language (PDL) files at one time. You determine which PDLs make up the Protocol Pack and then it allows you to load the protocols together rather than individually. Protocol Packs are easy to load, easy to upgrade to a higher version protocol pack or revert to a lower version protocol pack, and provides only the required set of protocols for your organization.

How to load the Cisco NBAR Protocol Pack


  1. enable
  2. configure terminal
  3. ip nbar protocol-pack protocol-pack [force]
  4. exit
  5. show ip nbar protocol-pack {protocol-pack | active} [detail]  

So why is this important? Configuring NBAR for Flexible NetFlow allows you to report on the protocols and applications exported to your NetFlow Analyzer. Following is an example of Flexible NetFlow NBAR reporting:

Cisco Applications NBAR report Now, by combining Flexible NetFlow, Network-Based Application Recognition, and the new NBAR Protocol Packs to easily load multiple protocols, application reporting on your network has just become that much simpler.
