Hierarchy Level

[edit security advance-policy-based-routing]


Create a set of metrics, which can be used by AppQoE to evaluate the SLA of the link.

A metrics profile defines the performance metrics for delay round trip, one-way jitter or two-way jitter, and packet loss.

To ensure compliance with the SLA, metrics are required to measure and monitor the network performance. This measurement capability provides a greater visibility into the performance characteristics of the links and helps in network performance evaluation.



Metrics profile name.

delay-round-trip delay-value

Sets the total round-trip time (in microseconds), from the device to the remote server, that triggers a probe failure.

jitter jitter-value

Total jitter (in microseconds) for a test, which, if exceeded, triggers a probe failure


Jitter type.

  • Values: Ingress jitter, egress jitter, and two-way jitter.

  • Default: Two-way jitter


Matching SLA metrics.


The path selection mechanism attempts to find a path that satisfies all the metrics. If no such path exists, then the next best path (based on number of metrics satisfied) is used. If there are more than one path that satisfy the metric, a random path among the available paths will be selected. Also, SLA violation will be detected and raised even if any one of the metrics is violated.

This is the default match option.


Path selection mechanism attempts to find a path which satisfies the maximum number of metrics. For example, if there is a path available that conforms to more than one metric, then the path is chosen over another path which satisfies less number of metrics. In this case, SLA violation is detected only when none of the metrics meets the requirement. If either one of the metric is meets the requirement, then violation is not triggered.

packet-loss loss-value

Percentage of number of packets that must be lost successively to trigger a probe failure.
