    Configure Internet Circuit Underlay Link Aggregation

    To configure Internet Underlay Link Quality in the LQ tab.
    Where Can I Use This?What Do I Need?
    • Prisma SD-WAN (Managed by Strata Cloud Manager)
    • Prisma SD-WAN
    Prisma SD-WAN supports Link Quality Monitoring (LQM) based path selection for all path types, including underlay, VPN, and Standard VPN. The ION device aggregates the overlay LQM values between branches and at least one or more data centers, branch gateways or Prisma Access RN-HP to compute the final LQM value for the internet underlay circuit or other required paths. By default, Use LQM for Non Hub Paths is disabled but can be enabled at the circuit or circuit category. To enable at the circuit level:
    1. Select ConfigurationPrisma SD-WANSites/Data CentersConfigurations.
    2. In the Connectivity and Circuits section, under Circuits Internet CircuitsChange Internet Circuits.
    3. Click Edit to view circuit information.
    4. In the LQM Configurations:
      • To enable LQ Monitoring for ongoing links quality measurements, such as latency, loss, and jitter select Yes. LQM is enabled by default on branch to data center paths.
      • Select one or more Data Centers to be the basis for Link Quality metrics for the internet underlay.
        If nothing is selected, by default, all data centers are chosen.
      • Select Yes from the Use LQM for Non Hub Paths for Link Quality metrics for the internet underlay.
      • From the Aggregation list, choose Minimum (lowest value of selected data centers), or Maximum (highest value of selected data centers), or Average (average value of selected data centers). By default, minimum will be selected.
      The Summary in Link Quality charts display minimum, maximum, or average link-level metrics based on selecting data centers and the aggregation method. The details are also displayed on the main Dashboard tab.
      The Aggregation list does not display if you select a single data center.
    5. Optionally, the setting is also controlled at the Circuit Category level (recommended). Please see for instructions on editing a circuit category.
