(Optional) Configuring Scheduling Parameters of a CQ

(Optional) Configuring Scheduling Parameters of a CQ

In upstream HQoS scheduling on an Ethernet interface, CQs adopt the default scheduling setting of the system. To prevent congestion on the backbone network, you need to configure the downstream CQ on the Ethernet interface.

Context

In upstream HQoS scheduling on an Ethernet interface, CQs adopt the default scheduling setting of the system and is not configured by users.

Configuring the downstream CQ on an Ethernet interface is recommended so that the backbone network is not congested.

Do as follows on the downstream interface of the router:

Procedure

  1. Run system-view

    The system view is displayed.

  2. Run interface interface-type interface-number

    The interface view is displayed.

  3. Run port-queue cos-value { { pq | wfq weight weight-value | lpq } | shaping { shaping-value | shaping-percentage shaping-percentage-value } [ pbs pbs-value ] | port-wred wred-name | low-latency } * outbound

    A queue scheduling policy for different CQs is set.

    NOTE:

    You can configure eight CQ scheduling parameters respectively on one interface.

    When no CQ is configured, the system adopts the default CQ profile.

    • By default, the system performs PQ on the flow queues with the priorities of EF, CS6, and CS7.
    • By default, the system performs WFQ on the flow queues with the priorities of BE, AF1, AF2, AF3, and AF4. The scheduling weight proportion is 10:10:10:15:15.
    • By default, the system performs no traffic shaping.
    • The discarding policy defaults to Tail drop.

  4. Run commit

    The configuration is committed.
