Configuring QoS on the E-series Router

Several of the tasks for configuring QoS on your E-series router are optional.

To configure QoS on your E-series router:

1. Create and configure a traffic class.

See Chapter 2, Defining Service Levels with Traffic Classes and Traffic-Class Groups.

2. (Optional) Create one or more traffic-class groups.

See Chapter 2, Defining Service Levels with Traffic Classes and Traffic-Class Groups.

3. (Optional) To configure nondefault buffer management, create a queue profile.

See Chapter 3, Configuring Queue Profiles for Buffer Management.

4. (Optional) To configure RED or WRED, create a drop profile.

See Chapter 4, Configuring Dropping Behavior with RED and WRED.

5. (Optional) To gather rate statistics, create a statistics profile.

See Chapter 5, Gathering Statistics for Rates and Events in the Queue.

6. Configure a scheduler hierarchy with a scheduler profile.

See Chapter 6, QoS Scheduler Hierarchy Overview.

7. (Optional) Configure shaping:

• Configure shaping and shared shaping using the scheduler profile.

See Chapter 7, Configuring Rates and Weights in the Scheduler Hierarchy, Chapter 10, Configuring Simple Shared Shaping of Traffic, and Chapter 12, Configuring Compound Shared Shaping of Traffic.

• Configure shaping rates independent of the QoS profile and scheduler profile using QoS parameters.

See Chapter 24, Configuring a QoS Parameter.

8. Create a QoS profile. QoS profiles reference queue, drop, statistics, and scheduler profiles.

See Chapter 16, Configuring and Attaching QoS Profiles to an Interface.

9. Attach the QoS profile to one or more interfaces, or specify the profile as a QoS port-type profile for a given interface type.

See Chapter 16, Configuring and Attaching QoS Profiles to an Interface.
