auto qos classify
Usage Guidelines Use this command to configure the QoS for trusted interfaces within the QoS domain. The QoS domain
includes the switch, the network interior, and edge devices that can classify incoming traffic for QoS.
Auto-QoS configures the switch for connectivity with a trusted interface. The QoS labels of incoming
packets are trusted. For nonrouted ports, the CoS value of the incoming packets is trusted. For routed
ports, the DSCP value of the incoming packet is trusted.
To take advantage of the auto-QoS defaults, you should enable auto-QoS before you configure other QoS
commands. You can fine-tune the auto-QoS configuration after you enable auto-QoS.
