39 Configuring Differentiated Services This chapter describes how to configure the Differentiated Services (DiffServ) feature. DiffServ enables traffic to be classified into streams and given certain QoS treatment in accordance with defined per-hop behaviors. The topics covered in this chapter include: • DiffServ Overview • Default DiffServ Values • Configuring DiffServ (Web) • Configuring DiffServ (CLI) • DiffServ Configuration Examples DiffServ Overview Standard IP-based networks are designed to provide "best effort" data delivery service. Best effort service implies that the network delivers the data in a timely fashion, although there is no guarantee that it will. During times of congestion, packets may be delayed, sent sporadically, or dropped. For typical Internet applications, such as email and file transfer, a slight degradation in service is acceptable and in many cases unnoticeable. Conversely, any degradation of service has undesirable effects on applications with strict timing requirements, such as voice or multimedia. Configuring Differentiated Services 1085
