Configuring HQoS

To configure HQoS, perform the following steps which include creating a QoS profile and enabling QoS on a PPP Subscriber-Interface or L3-Interface.

Create Behavioral Aggregate (BA) and/or Multifield (MF) classifier to classify the network traffic at the ingress.
Create a policer to police the classified traffic at the ingress.
Create necessary class-to-policer-map to map the classes to policer-levels (mandatory for policing).
Create queue-groups and configure the queue numbers (1/4/8) in the queue group.
NOTE: For the system to initialize with a single queue in a Queue-Group, a system reboot is required.
Create necessary queues with proper size to queue the classified traffic at the egress.
Create necessary class-to-queue-map to map the classes to queues (mandatory for queuing).
Specify scheduler(s) with type as required.
(Optional) Attach a shaper to queue(s) and/or scheduler(s).
Specify a scheduler map to define set of relationships between parent (scheduler or port) and child (queue/queue-group or scheduler) at the egress.
(optional) Create Remark-Map for QoS field remarking of the outgoing packet.
Define a QoS profile with classifier, multifield-classifier, class-policer-map, policer, class-queue-map, scheduler-map, and remark-map based on user requirements.
Specify another scheduler map to represent level-3 to level-5 hierarchy in multi-level HQoS and map it to physical interface.
Map the MPLS EXP classifier either to an instance or configure it as global entity.
(optional) Map the MPLS-IPv4/IPv6 remark-map either to an instance or configure it as global entity.
For downstream MPLS traffic, map the Multifield (MF) classifier as global entity.

Priority propagation is enabled by default. To disable the Priority Propagation, we recommend doing this at the beginning and not during an active session.

The figure below shows the dependencies between the various HQoS configuration elements.

The figure below shows the dependencies for per instance or global classifier and remark-map configurations.

The figure below shows the additional dependencies for Multi-level HQoS.

The figures below show the scheduling hierarchy example.

Queue to scheduler

Syntax

set forwarding-options class-of-service queue-group-name <queue-group-name> queue-name <name> parent-scheduler <parent-scheduler-name>

set forwarding-options class-of-service queue-group-name <queue-group-name> queue-name <name> parent-flow <parent-flow>

set forwarding-options class-of-service queue-group-name <queue-group-name> queue-name <name> [weight <weight>]

The parent-flow configuration is optional.

Example

Shaper Configuration

Syntax

set forwarding-options class-of-service shaper <shaper-name>

Command Arguments

<shaper-name>

User-defined shaper name

<shaping-rate-high>

High flow shaping rate in kilobits per second

<shaping-rate-low>

Low flow shaping rate in kilobits per second

Example

root@rtbrick: cfg> set forwarding-options class-of-service shaper session_shaper
root@rtbrick: cfg> commit

High Flow Shaping Rate

To configure only high-flow shaping rate, enter the following command:

set forwarding-options class-of-service shaper <shaper-name> shaping-rate-high <shaping-rate-high>

Example

root@rtbrick: cfg> set forwarding-options class-of-service shaper shaper_LD shaping-rate-high 2488000
root@rtbrick: cfg> commit

Low Flow Shaping Rate

To configure only low-flow shaping rate, enter the following command:

set forwarding-options class-of-service shaper <shaper-name> shaping-rate-low <shaping-rate-low>

If priority propagation is not enabled, high-flow shaping value will be considered for shaper.
If the scheduler type is strict_priority, the mapping of queues to priorities begins with strict_priority_1.

Example

root@rtbrick: cfg> set forwarding-options class-of-service shaper shaper_LD shaping-rate-low 0
