Examples

Example-1: This example demonstrates how to configure Application Aware Routing policy, which matching traffic based on Application Group (VOICE-APPS and BUSINESS-APPS, etc) and as an actions applying target SLA classes together with preferred color (or color group) with option of fallback to the best path (transport) in case SLA is not met. Each sequence has counter enabled.
