Description
To use Differentiated Services Code Point (DSCP) markings to
classify traffic, click DSCP marking (trusted). Cisco network
devices such as IP phones and switches add DSCP markings to
packets. Configuring DSCP on the router allows these markings to
be used to classify traffic. If the Cisco IOS image on the router does
not support DSCP marking, this option will not appear.
To use Networked Based Application Recognition (NBAR) protocol
discovery to classify traffic, click NBAR protocol discovery
(untrusted). When an application is recognized and classified by
NBAR, a network can invoke services for that specific application.
NBAR ensures that network bandwidth is used efficiently by
classifying packets and then applying Quality of Service (QoS) to
the classified traffic. If the Cisco IOS image on the router does not
support NBAR protocol discovery, this option will not appear.
In this screen, configure queuing for outbound traffic.
Field Reference

A traffic class is a specific type of traffic, such as voice traffic and
routing traffic. The Cisco SDM default traffic classes and
user-created traffic classes are listed in this column.
