QoS CIR Support For Aggregate Bandwidth

315 PA
In Aggregate Bandwidth licensing mode, the bandwidth allocation is done for a compute location on Prisma Access. The number of tunnels terminating within a compute location and SPN share the aggregate bandwidth allocated. You must configure the CIR for specific tunnels terminating on an SPN within a compute location to guarantee the Quality of Service (QoS).
Follow these steps to configure Quality of Service (QoS) in Panorama for aggregate bandwidth, including adding a QoS profile, enabling QoS, and tagging the QoS profile on the Prisma SD-WAN interface.
The minimum Prisma Access cloud plugin version for the QoS CIR feature is
3.0.0-H24
.
  1. Add a
    QoS Profile
    .
    You can edit any existing QoS profile, including the default, by clicking the QoS profile name.
    1. In Panorama, select
      Network
      Network Profiles
      QoS Profile
      and
      Add
      a new profile.
    2. Enter a descriptive
      Profile Name
      .
    3. Set the overall bandwidth limits for the QoS profile rule.
      • Enter an
        Egress Max
        value to set the overall bandwidth allocation for the QoS profile rule.
      • Enter an
        Egress Guaranteed
        value (bandwidth that is the guaranteed bandwidth for this profile (in Mbps).
      Any traffic that exceeds the Egress Guaranteed value is best effort and not guaranteed. Bandwidth that is guaranteed but is unused continues to remain available for all traffic.
    4. In the Classes section,
      Add
      one or more classes and specify how to mark up to eight individual QoS classes.
      • Add a class to the QoS Profile.
      • Select the
        Priority
        for the class (either
        real-time
        ,
        high
        ,
        medium
        , or
        low
        ).
      • Enter the
        Egress Max
        and the
        Egress Guaranteed
        for traffic assigned to each QoS class.
      • Enter a
        Class Bandwidth Type
        for the profile.
    5. Click
      OK
      .
    6. Select
      Commit and Push
      to save the changes.
  2. For
    Default QoS Profiles
    , enable QoS for your remote network locations that allocate bandwidth by compute location.
    1. Determine the Prisma Access locations where you want to deploy QoS; then find the compute location that corresponds to each location.
      Each location is allocated bandwidth from its compute location, and you must know the name of the compute location for the locations where you want to allocate QoS. For a list of compute location-to-location mapping, see Prisma Access Locations by Compute Location, or select
      Panorama
      Cloud Services
      Configuration
      Remote Networks
      Aggregate Bandwidth
      and click the gear icon; the mappings display in the
      Compute Location
      and
      Prisma Access Location
      columns.
    2. Select
      Panorama
      Cloud Services
      Configuration
      Remote Networks
      Settings
      , click the gear to edit the settings, and select
      QoS
      .
    3. Enable QoS
      at a compute location level.
      Whatever settings you enter apply to all locations that correspond to this compute location.
    4. In the case of default QoS profiles, you must enter the
      QoS Profile
      , and the Guaranteed Bandwidth Ratio.
    5. Select
      Commit
      and
      Push
      to save the changes.
      The default QoS profile does not require any configuration changes to be done in Prisma SD-WAN.
  3. Customize QoS per Site.
    1. In Panorama, go to
      Settings
      QoS
      and select the site that you wish to customize.
      If you do not wish to use the default profile on the sites, the profile can be customized by using Interface/Circuit level tags in Prisma SD-WAN.
    2. Check the
      Customize Per Site
      checkbox and click
      OK
      .
    3. Select
      Commit
      and
      Push
      to save the changes.
  4. In Prisma SD-WAN, navigate to the
    Site
    Interfaces/Circuits
    and assign interface level tags in the following format.
    prisma_qos:<profile_name>:[0-100]
    The profile name for QoS will be the same name as the profile created in Step 1.
    Interface/Circuit level tagging can be done for both ECMP and Non-ECMP enabled sites in Prisma SD-WAN.
    • Non-ECMP
      : Go to the site on Prisma SD-WAN where you wish to customize QoS and tag the interface or circuit. In the example shown below, the allocated bandwidth is 20%.
      After you tag the Interface/Circuit, the CloudBlade integration applies these changes on Panorama.
    • ECMP
      : enabled sites allow customizations per ECMP link. You must tag the ECMP links where you want to apply the QoS customization.
      After the tags are applied, the CloudBlade integration applies these changes on Panorama.
