Usage Guidelines
Use this command to configure the QoS for trusted interfaces within the QoS domain. The QoS domain
includes the device, the network interior, and edge devices that can classify incoming traffic for QoS. When
auto-QoS is enabled, it uses the ingress packet label to categorize traffic, to assign packet labels, and to
configure the ingress and egress queues.
