Layer 3 QoS
This chapter describes how to create and configure Layer 3 QoS (Quality of Service), Committed Access
Rate (CAR) policies, Cos Queue groups and Weighted Random Early Detection To-Fabric (WRED
ToFab) policies.
The Layer 3 QoS dialogs are not available for the 10720 chassis.
This chapter contains the following information:
• Launching the Layer 3 QoS Windows
• CAR and WRED Overview
• The Workflow for CAR
• CAR Policy Configuration
• Access List Configuration
• CAR Policy Apply
• CAR Policy Status
• The Workflow for WRED/DRR
• CoS Queue Group Configuration
• WRED Tx Configuration
• WRED ToFab Configuration
• WRED Rx Configuration
Launching the Layer 3 QoS Windows
Table 11-1 displays the Layer 3 QoS windows that can be launched from each of the available object
types. For example, the CAR Policy Configuration window can be launched for 12000 Series Router
chassis from a Site, Chassis, Module, Interface or a CAR Policy, but not from the WRED-MDRR
container or a CoS Queue Group object.
Note Table 11-1 lists the menu options to launch the Layer3QoS dialogs from the site level.
