Configuring AVC with DNS-AS
Sample QoS Configuration for AVC with DNS-AS: Classifying Network Control Traffic
The following example shows how to classify network-control traffic based on the 12-class Easy QoS
model. It shows how the DNS-AS client allows “example.org” to be classifed under class-map
NETWORK-CONTROL.
For this example, the corresponding metadata that should be maintained is:
CISCO-CLS=app-name:example|app-class:NC|business:YES
Create class maps and match attributes
Switch# configure terminal
Enter configuration commands, one per line. End with CNTL/Z.
Switch(config)# class-map NETWORK-CONTROL
Switch(config-cmap)# match protocol attribute traffic-class network-control
Switch(config-cmap)# match protocol attribute business-relevance business-relevant
Switch(config-cmap)# end
Create the policy map, attach the class map to it and specify priority
Switch# configure terminal
Enter configuration commands, one per line. End with CNTL/Z.
Switch(config)# policy-map MARKING
Switch(config-pmap)# class NETWORK-CONTROL
Switch(config-pmap-c)# set dscp ef
Switch(config-pmap-c)# end
Switch#
