Page: 41 / 398

To configure QoS on your E Series router:
1.
Create and configure a traffic class.
See “Traffic Class and Traffic-Class Groups Overview” on page 13.
2.
(Optional) Create one or more traffic-class groups.
See “Traffic Class and Traffic-Class Groups Overview” on page 13.
3.
(Optional) To configure nondefault buffer management, create a queue profile.
See “Queuing and Buffer Management Overview” on page 17.
4.
(Optional) To configure RED or WRED, create a drop profile.
See “Dropping Behavior Overview” on page 25.
5.
(Optional) To gather rate statistics, create a statistics profile.
See “QoS Statistics Overview” on page 37.
6.
Configure a scheduler hierarchy with a scheduler profile.
See “Scheduler Hierarchy Overview” on page 45.
7.
(Optional) Configure shaping:
■
Configure shaping and shared shaping using the scheduler profile.
See “Rate Shaping and Port Shaping Overview” on page 51, “Simple Shared
Shaping Overview” on page 79, and “Compound Shared Shaping Overview”
on page 99.
■
Configure shaping rates independent of the QoS profile and scheduler profile
using QoS parameters.
See “Parameter Definition Attributes for QoS Administrators Overview” on
page 229.
8.
Create a QoS profile. QoS profiles reference queue, drop, statistics, and scheduler
profiles.
See “Queuing and Buffer Management Overview” on page 17.
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 “Queuing and Buffer Management Overview” on page 17.
