Chapter 28 Configuring QoS

Configuring Standard QoS

Configuring the Trust State on Ports within the QoS Domain

Packets entering a QoS domain are classified at the edge of the QoS domain. When the packets are

classified at the edge, the switch port within the QoS domain can be configured to one of the trusted

states because there is no need to classify the packets at every switch within the QoS domain.

Figure 28-11 shows a sample network topology.
