Controlling traffic flow with SD-WAN (voice traffic example)

Creating a voice traffic SLA profile

The configuration is made on a branch template and not on an individual appliance. 

Step 1—configuring SD-WAN SLA profiles

A service level agreement (SLA) defines the network performance parameters between your organization and CenturyLink and includes packet delay, packet loss, and jitter profiles.

Step 2—configuring SD-WAN forwarding profiles

A forwarding profile determines the traffic path based on realtime SLA performance of traffic. A forwarding profile defines the properties such as load balancing method, priority of circuits, circuit type, circuit media, and others to be selected for traffic.

Step 3—configuring SD-WAN policies and rules

An SD-WAN policy called the Default-Policy will have already been created.

The last step is to apply these changes to your branches.
