RE: Classifying traffic with/without NBAR

Thanks for the answers.
Strange, because there's this statement in the Classifying Traffic using
NBAR section of the QoS DocCD
http://www.cisco.com/en/US/docs/ios/qos/configuration/guide/nbar_mqc_ps6441_
TSD_Products_Configuration_Guide_Chapter.html

rerequisites for Configuring NBAR Using the MQC

.Before configuring NBAR using the MQC, read the information in the
"Classifying Network Traffic Using NBAR" module.

.As applicable, enable Protocol Discovery and use it to obtain statistics
about the protocols and applications that are used in your network. You will
need this information when using the MQC.

Anyways, you've answered my question, so thanks! :)

Confirmed.

"match protocol [...]" invokes NBAR
"ip nbar protocol-discovery" is not required to make "match protocol [...]"
work "ip nbar protocol-discovery" operates independently from "match
protocol [...]"
