Ken,
The simple command: 'ip nbar protocol-discovery' on an IP interface will
cause the router to build a table of statistics, showing you protocol
distribution on that interface, such as:
border-router#sh ip nbar pro
Serial0/0.1
Input Output
Protocol Packet Count Packet Count
Byte Count Byte Count
5 minute bit rate (bps) 5 minute bit rate (bps)

It'll show all the protocols it supports. Still need CEF. Keep in mind that
some such as Kazaa2 were added later, thus requiring a newer version, such as
12.2.13T, I think. You're right though, it's pretty cool.

Subject: Is this NBAR? Is it not?
Guys, It's been a day of QoS so by now, I just wanna permit IP any any )
NBAR ? what is it? Is it just the fact that now you can use this command
(and others for MIME etc etc) under a class map?
match protocol http url "/exec/show/interface/*" and a shed load of other
protocols/commands under the class-map for further in-depth classification?
Is that the strength of it? Just added protocols under this command? so you
can look further into the packet?
YOU DONT NEED ANY NBAR COMMANDS do you? I know you need CEF running
Please could you be so kind to advise?
!
class-map match-all http_interface
match protocol http url "/exec/show/interface/*"
class-map match-all http_log
match protocol http url "/exec/show/log/*"

set ip precedence 5
class http_log
