Configuring QoS for AVC with DNS-AS
In order to isolate and classify trusted traffic as defined in the metadata stream, you must complete this
sequence of tasks—create class maps (one for each traffic class), define traffic-class match criteria and
business-relevance match criteria, create a policy map, attach the policy map to the interface. This
sub-section provides the following information:
• Class Map Configuration in the Easy QoS Model, page 45-11
• Policy Map Definitions in the Easy QoS Model, page 45-12
• App-Class and QoS Traffic Mapping, page 45-12
• Sample QoS Configuration for AVC with DNS-AS: Classifying Network Control Traffic,
page 45-13
For more QoS information, see the Classification, page 44-6 section of the Configuring QoS chapter in
this guide.
Class Map Configuration in the Easy QoS Model
In order to determine how many traffic classes should be provisioned, you can use the 12-class Easy QoS
Model. This model provides uniform, standards-based recommendations to help ensure that QoS designs
and deployments are unified and consistent across an organization.
The following shows the class map configuration for traffic class and business relevance as per the
12-class Easy QoS Model:
class-map match-all VOICE
match protocol attribute traffic-class voip-telephony
match protocol attribute business-relevance business-relevant
class-map match-all BROADCAST-VIDEO
