Configuring a Subscriber Queue

Configuring a Subscriber Queue

Background

You can set different traffic shaping rates for different users by configuring subscriber queues so that the device provides higher bandwidth for high-priority users. Traffic from different users is differentiated based on ACLs that define items such as the source and destination MAC addresses, source and destination IP addresses, and VLAN IDs.

Pre-configuration Tasks

Before configuring a subscriber queue, configure an ACL.

Procedure

  1. Run system-view

    The system view is displayed.

  2. Run interface interface-type interface-number

    The interface view is displayed.

  3. Run the following commands as required.

    • Run traffic-user-queue outbound acl { [ ipv6 ] { bas-acl | adv-acl | name acl-name } } pir pir-value [ flow-queue-profile flow-queue-profile-name | flow-mapping-profile flow-mapping-profile-name ] *

      The device is configured to shape packets in a subscriber queue matching a single ACL rule and to reference the flow queue and flow mapping profile to implement HQoS.

    • Run traffic-user-queue outbound acl { l2-acl | name acl-name } acl { bas-acl | adv-acl | name acl-name } pir pir-value [ flow-queue-profile flow-queue-profile-name | flow-mapping-profile flow-mapping-profile-name ] *

      The device is configured to shape packets in a subscriber queue matching both Layer 2 and Layer 3 ACL rules and to reference the flow queue and flow mapping profile to implement HQoS.

    • Run traffic-user-queue outbound acl { bas-acl | adv-acl | name acl-name } acl { l2–acl | name acl-name } pir pir-value [ flow-queue-profile flow-queue-profile-name | flow-mapping-profile flow-mapping-profile-name ] *

      The device is configured to shape packets in a subscriber queue matching both Layer 2 and Layer 3 ACL rules and to reference the flow queue and flow mapping profile to implement HQoS.
