Traffic Class app-class:<class>
SRND is a 12-Class QoS classification model based on RFC 4594, which is very commonly used among enterprises and is well supported in NBAR and in other network elements and services from Cisco. Therefore, the most important and useful attributes are the ones used by the SRND QOS feature by default – traffic-class and business-relevance. Using these values should be as simple as possible, therefore short notations for these values are proposed.
This also aligns with the classification done by APIC-EM Easy QoS app or other SRND 4.0 based QoS provisioning solutions.
Below are the supported values for Traffic Class and Business Relevance, along with the shortcuts and the Business Relevance defaults per class.
| APPLICATION CLASS | APPLICATION CLASS long | APPLICATION CLASS short | BUSINESS-RELEVANCE | DSCP | COS | WMM | QUEUING & DROPPING | APPLICATION EXAMPLES |

The idea here is to use the same traffic-class name like being used inside the C3PL policy map to move applications seamlessly into the right traffic-class.
