SLA Class

A SLA class defines the maximum jitter, maximum latency, maximum packet loss, or a combination of these values, for the Cisco SD-WAN data plane tunnels. The SLA classes are used in Application-Aware Routing Policies.

Examples

Example-1: The following example demonstrates how to configure an SLA class. The sla class sla_realtime has a jitter of 20ms, a latency of 100ms, and a loss of 1%, with a fallback criteria of jitter and a jitter variance of 40ms.

sdwan:
  feature_profiles:
    policy_object_profile:
      sla_classes:
        - name: sla_realtime
          jitter_ms: 20
          latency_ms: 100
          loss_percentage: 1
          fallback_best_tunnel_criteria: jitter
          fallback_best_tunnel_jitter_variance: 40
