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 subscriber queues (SQs) include the committed information rate (CIR), peak information rate (PIR), flow queue profile, and network header length for service profiles.

Context

Perform the following steps on the router to be configured with HQoS:

Procedure

  1. Run system-view

    The system view is displayed.

    NOTE:

    You can configure scheduling parameters in a common QoS profile (as described in Step 2) or a time-based QoS profile (as described in Step 3). A maximum of two user queue configurations can be configured in a time-based QoS profile.

    • The names of the common QoS profile and time-based QoS profile must be different.

    • If you have configured one time-based user queue, configuring one more non-time-based user queue is recommended. Within the time range, the time-based user queue takes effect; at other time, the non-time-based user queue takes effect.

    • If you need to configure two time-based user queues, configuring the two time ranges to cover the full day (24 hours) is recommended. If the two time ranges do not cover the full day (24 hours), the user queue does not take effect at the unspecified time.

  2. Configure scheduling parameters in a common QoS profile.
    1. Run qos-profile qos-profile-name

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

    2. You can choose to configure scheduling parameters for SQs or traffic assurance for users as required.

      • Run user-queue cir-value [ cbs cbs-value ] [ [ pir pir-value [ pbs pbs-value ] [ pir-priority high ] ] | [ flow-queue flow-queue-name ] | [ queue-4cos-mapping queue-mapping-name ] | [ flow-mapping mapping-name ] | [ user-group-queue group-name ] ] * [ inbound | outbound ] [ service-template service-template-name [ adjust-on-card ] ]

        Scheduling parameters are configured to implement HQoS for user services.

        The parameter queue-4cos-mapping is supported only on the Admin-VS.

      • Run car { cir cir-value [ pir pir-value ] | cir cir-percentage cir-percentage-value [ pir pir-percentage pir-percentage-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 ]

        CAR is configured.

      • (Optional) Run weight value [ outbound | inbound ]

        A weight value is set.

      • Run broadcast-suppression cir cir-value [ cbs cbs-value ] [ inbound | outbound ]

        Broadcast suppression is configured.

      • Run multicast-suppression cir cir-value [ cbs cbs-value ] [ inbound | outbound ]

        Multicast suppression is configured.

      • Run unknown-unicast-suppression cir cir-value [ cbs cbs-value ] [ inbound | outbound ]

        Unknown unicast suppression is configured.

      • Run bu-suppression cir cir-value [ cbs cbs-value ] inbound

        broadcast and unknown unicast suppression is configured.

      • Run bum-suppression cir cir-value [ cbs cbs-value ] inbound

        broadcast, unknown unicast, and multicast suppression is configured.

      NOTE:
      • If the qos-profile command has been configured on an interface, you cannot configure the car command, or the suppression command on the interface.

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

  3. Configure scheduling parameters in a time-based QoS profile.
    1. Run qos-profile qos-profile-name time-range

      A time-based QoS profile is defined, and the QoS profile time-range view is displayed.

    2. Run user-queue 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 ] ] time-range time-range-name

      Scheduling parameters are configured to implement HQoS and take effect within the time range.

      NOTE:
      • This command can be configured only in the QoS profile time-range view.

  4. Run commit

    The configuration is committed.
