Defining a QoS Policy in the IPQoS Configuration File (Task Map)

This task map lists the general tasks for creating an IPQoS configuration file.

Task

Description

For Instructions

1. Plan your IPQoS-enabled network configuration.

Decide which systems on the local network should become IPQoS enabled.

2. Plan the QoS policy for IPQoS systems on your network.

Identify traffic flows as distinct classes of service. Then, determine which flows require traffic management.

3. Create the IPQoS configuration file and define its first action.

Create the IPQoS file, invoke the IP classifier, and define a class for processing.

4. Create filters for a class.

Add the filters that govern which traffic is selected and organized into a class.

5. Add more classes and filters to the IPQoS configuration file.

Create more classes and filters to be processed by the IP classifier.

6. Add an action statement with parameters that configure the metering modules.

If the QoS policy calls for flow control, assign flow-control rates and conformance levels to the meter.

7. Add an action statement with parameters that configure the marker.

If the QoS policy calls for differentiated forwarding behaviors, define how traffic classes are to be forwarded.

8. Add an action statement with parameters that configure the flow-accounting module.

If the QoS policy calls for statistics gathering on traffic flows, define how accounting statistics are to be gathered.

9. Apply the IPQoS configuration file.

Add the content of a specified IPQoS configuration file into the appropriate kernel modules.

10. Configure forwarding behaviors in the router files.

If any IPQoS configuration files on the network define forwarding behaviors, add the resulting DSCPs to the appropriate scheduling files on the router.
