Defining a QoS Profile and Configuring Scheduling Parameters

Defining a QoS Profile and Configuring Scheduling Parameters

A QoS profile is the aggregate of QoS scheduling parameters. Configurable scheduling parameters for SQs include CIR, PIR, Flow Queue (FQ) profiles, and lengths for packet loss compensation of service profiles.

Context

Perform the following steps on the router:

Procedure

  1. Run system-view

    The system view is displayed.

  2. Run qos-profile qos-profile-name

    A QoS profile is defined and the QoS profile view is displayed.

  3. You can choose to configure user queue scheduling and traffic assurance for users as required.

    • To configure user queue scheduling parameters to implement HQoS for user services, run the user-queue cir cir-value [ cbs cbs-value ] [ [ pir pir-value [ pbs pbs-value ] [ pir-priority high ] ] | [ flow-queue flow-queue-name ] | [ flow-mapping mapping-name ] | [ user-group-queue group-name ] ] * [ inbound | outbound ] [ service-template service-template-name ] [ adjust-on-card ] command.
    • (optional)Run user-queue cir-percentage cir-percentage-value [ cbs cbs-value ] [ [ pir-percentage pir-percentage-value [ pbs pbs-value ] [ pir-priority high ] ] | [ flow-queue flow-queue-name ] | [ flow-mapping mapping-name ] ] | [ user-group-queue group-name ] ] * [ inbound | outbound ] [ service-template service-template-name [ adjust-on-card ] ] ,To allow the CIR/PIR of an Eth-Trunk interface or sub-interface to automatically change with the Eth-Trunk interface bandwidth, specify cir-percentage or pir-percentage in the command.
      NOTE:

      Only Eth-Trunk interfaces and sub-interfaces support the QoS profile in which cir-percentage or pir-percentage is configured.

    • To configure the CAR function to implement traffic assurance for users, run the car { cir cir-value [ pir pir-value ] } [ cbs cbs-value [ pbs pbs-value ] ] [ green { discard | pass [ service-class class color color ] } | yellow { discard | pass [ service-class class color color ] } | red { discard | pass [ service-class class color color ] } ]* [ inbound | outbound ] [ color-aware ] command.
    • To configure CAR parameters for L2 or L3 traffic, run the car access-user { l2 | l3 } { cir cir-value [ pir pir-value ] } [ cbs cbs-value [ pbs pbs-value ] ] [ { green { discard | pass [ service-class class color { green | yellow | red } ] } } | { yellow { discard | pass [ service-class class color { green | yellow | red } ] } } | { red { discard | pass [ service-class class color { green | yellow | red } ] } } ] * [ inbound | outbound ] [ color-aware ] command.

      This command is supported only on the Admin-VS.

    NOTE:

    A corresponding service profile must have been globally configured before HQoS is configured in a QoS profile.

  4. Run commit

    The configuration is committed.
