NBAR2 Dynamic Hitless Protocol Pack Upgrade
Protocol packs are software packages that update the NBAR2 protocol support on a device without replacing
the Cisco software on the device. A protocol pack contains information on applications officially supported
by NBAR2 which are compiled and packed together. For each application, the protocol-pack includes
information on application signatures and application attributes. Each software release has a built-in
protocol-pack bundled with it.
Protocol packs provide the following features:
• They are easy and fast to load.
• They are easy to upgrade to a higher version protocol pack or revert to a lower version protocol pack.
• They do not require the switch to be reloaded.
Warning
When using switch stacking, ensure that each switch has the same Protocol Pack file loaded. If you execute
the ip nbar protocol-pack flash protocol-pack-file command on the primary switch in the stack, any switch
in the stack that does not have the file loaded will be reloaded due to a configuration mismatch.
NBAR2 protocol packs are available for download on Cisco Software Center from this URL:

Prerequisites for the NBAR2 Protocol Pack
Before loading a new protocol pack, you must copy the protocol pack to the flash on all the switch members.
