Quality of Service 3

Creating QoS Policies

This function creates a policy map that can be attached to multiple interfaces.

Command Usage

•To configure a Policy Map, follow these steps:

-Create a Class Map as described on page 3-162.

-Open the Policy Map page, and click Add Policy.

-When the Policy Configuration page opens, fill in the “Policy Name” field, and click Add.

-When the Policy Rule Settings page opens, select a class name from the scroll-down list (Class Name field). Configure a policy for traffic that matches criteria defined in this class by setting the quality of service that an IP packet will receive (in the Action field), defining the maximum throughput and burst rate (in the Meter field), and the action that results from a policy violation (in the Exceed field). Then finally click Add to register the new policy.

•A policy map can contain multiple class statements that can be applied to the same interface with the Service Policy Settings (page 3-168). You can configure up to 63 policers (i.e., class maps) for Fast Ethernet and Gigabit Ethernet ingress ports, and up to 225 policers for 10G Ethernet ingress ports.

Policing is based on a token bucket, where bucket depth (i.e., the maximum burst before the bucket overflows) is by specified the “Burst” field, and the average rate tokens are removed from the bucket is by specified by the “Rate” option.

•After using the policy map to define packet classification, service tagging, and bandwidth policing, it must be assigned to a specific interface by a service policy (page 3-168)to take effect.

Command Attributes
