Hi,
First , thanks for your input.
As you can see in the following output CEF, is not running.
2503UP#sh ip cef
%CEF not running
Prefix Next Hop Interface
How can I check that NBAR is running ?
I created a class-map that match ip protocol and then in the policy map, I used policing (to limit the traffic rate).
When I ping, some packets are lost (there are no traffic at all on the link, I'm in a lab).
It means that NBAR is working !!
Bye

AFAIK, CEF is needed but may be it is enabled by default
in the image you're running ?
Do a show ip cef to see.
How do you tell that it is working ?
