A. Cisco IOS logical interfaces do not inherently support a state of congestion and do not support the direct application of a service policy that applies a queueing method. Instead, you first need to apply shaping to the subinterface using either Generic Traffic Shaping (GTS) or class-based shaping. For more information, refer to Applying QoS Features to Ethernet Subinterfaces.
