QoS CIR Support For Aggregate Bandwidth
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
- Add aQoS Profile.You can edit any existing QoS profile, including the default, by clicking the QoS profile name.
- In Panorama, selectandNetworkNetwork ProfilesQoS ProfileAdda new profile.
- Enter a descriptiveProfile Name.
- Set the overall bandwidth limits for the QoS profile rule.
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.
- Enter anEgress Maxvalue to set the overall bandwidth allocation for the QoS profile rule.
- Enter anEgress Guaranteedvalue (bandwidth that is the guaranteed bandwidth for this profile (in Mbps).
- In the Classes section,Addone or more classes and specify how to mark up to eight individual QoS classes.
- Add a class to the QoS Profile.
- Select thePriorityfor the class (eitherreal-time,high,medium, orlow).
- Enter theEgress Maxand theEgress Guaranteedfor traffic assigned to each QoS class.
- Enter aClass Bandwidth Typefor the profile.
- SelectCommit and Pushto save the changes.
- ForDefault QoS Profiles, enable QoS for your remote network locations that allocate bandwidth by compute location.
- 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 selectand click the gear icon; the mappings display in thePanoramaCloud ServicesConfigurationRemote NetworksAggregate BandwidthCompute LocationandPrisma Access Locationcolumns.
- Select, click the gear to edit the settings, and selectPanoramaCloud ServicesConfigurationRemote NetworksSettingsQoS.
- Enable QoSat a compute location level.Whatever settings you enter apply to all locations that correspond to this compute location.
- In the case of default QoS profiles, you must enter theQoS Profile, and the Guaranteed Bandwidth Ratio.
- SelectCommitandPushto save the changes.The default QoS profile does not require any configuration changes to be done in Prisma SD-WAN.
- Customize QoS per Site.
- In Panorama, go toand select the site that you wish to customize.SettingsQoSIf 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.
- Check theCustomize Per Sitecheckbox and clickOK.
- SelectCommitandPushto save the changes.
- In Prisma SD-WAN, navigate to theand assign interface level tags in the following format.SiteInterfaces/Circuitsprisma_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.
