Which command must be configured on WAN Edge 5000 routers to apply a QoS scheduling policy for traffic received from transport-side tunnels?

The cloud-qos command is specifically designed for Cisco Catalyst SD-WAN (formerly Viptela) WAN Edge 5000 routers to apply QoS scheduling policies to traffic received from transport-side tunnels. This command enables the router to prioritize and manage traffic flows as they enter the SD-WAN fabric from the underlying transport network. mls qos is a command used on traditional Cisco IOS switches and routers for Modular QoS CLI (MQC) configurations, not specific to SD-WAN transport-side tunnel QoS on WAN Edge 5000s. service qos is not a standard Cisco IOS XE SD-WAN command for this specific function. cloud-mls qos is a syntactically incorrect command; the correct SD-WAN-specific command for this purpose is cloud-qos.
