Nope. If you want to use it for discovering information at the interface
you do. But class-maps do not need that command.
According to the DocCD:
"NBAR can determine which protocols and applications are currently running
on a network. NBAR includes the Protocol Discovery feature that provides an
easy way of discovering application protocols operating on an interface so
that appropriate QoS policies can be developed and applied. With Protocol
Discovery, you can discover any protocol traffic supported by NBAR and
obtain statistics associated with that protocol."
So sa a good real-life rule, it's always nice to accurately know what stuff
is really traversing your network before you decide to implement some policy
about it all... But for the lab (and in case you feel lucky (punk?)) then
you can configure the class maps without any direct knowledge of discovered
information.

Guys
A quick question.
If I apply service-policy using nbar in class map, do I have to enter this
command "ip nbar protocol-discovery" for nbar to work?
So something like this?
interface E0/0
ip nbar protocol-discovery
service-policy input www
Thanks
Jongsoo
