Ken,
The paragraph you're quoting doesn't mention the
protocol-discovery command. It mentions that NBAR is started by using
the service-policy command, which is correct. Protocol-discovery gives
you a nice breakdown of protocol distribution on an interface, using 'sh
ip nbar protocol-discovery'. Or via SNMP, I recently heard. But it's
not needed for the class-map, policy-map, and service-policy commands to
use NBAR. Enabling either the service-policy or the protocol-discovery
will start the NBAR process, which you can see via the resulting 1 mbyte
or more drop in available memory right off the bat.

According to page 185 of Odom's DQOS Exam Certification Guide by Cisco
Press, "ip nbar protocol-discovery" is required on the interface...
<snip>
"The connection between NBAR and CB marking, or any other MQC tool, is
through the match protocol class-map subcommand. An MQC tool can include
the match protocol command under a class-map command. To do so, NBAR
must be enabled on the same interface on which the class map is
indirectly enabled through the service-policy interface subcommand."
</snip>
Any thoughts?
Ken

Subject: NBAR question
When I want to use match protocol under class-map, Is
it necessary to config ip nbar protocol-discovery?
Thanks.
