Introduction

Enough with theory, I suppose. Now it is time to show you how to configure all of the things that we discussed in the last chapter. This chapter shows you how to put into practice all of the theories that were introduced in the last chapter, how you would implement these technologies in your network.

This chapter contains many configuration examples, but is by no means a complete listing of all possible uses for the technologies presented.

The configurations presented center on the Quality of Service (QoS) configuration steps required. Basic configuration of interfaces and devices is not discussed. Remember that the classification examples we show are only one part of the equation. After a packet is classified, an appropriate queuing mechanism must be configured on the devices to provide the required QoS. For details on configuring the queuing mechanisms required, please see the relevant chapters in this text.

We strongly encourage you to visit the Cisco Web site at www.cisco.com to view more configuration examples, as new uses for these mechanisms are constantly being developed. Cisco s Web site has one of the best collections of configuration examples available.

What we hope that we have done here is provide you with excellent examples for the most popular uses of these technologies. By doing so, it is our hope that you will use this book as a reference when you are configuring these mechanisms on your network.
