App-Class and QoS Traffic Mapping
The following table shows how the app-class field in the metadata stream maps to the 12-class Easy QoS
Model of traffic classification:
Note
The DNS-AS client applies default forwarding behavior in these cases:
• If the match attributes that you specify for the traffic class and business relevance do not match what
you have defined in the metadata stream.
•
If the binding table entry is no longer active. This refers to the age of the entry. Use the show avc
dns-as client binding-table command to display the age of an entry
