Configuring The Trust State On Ports Within The Qos Domain - Cisco WS-C3560-48PS-S Software Configuration Manual

Chapter 28 Configuring 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.
