Defining a QoS Policy and Applying the QoS Policy to an Interface
A policy applied to an interface takes effect on the traffic sent or received by the interface.
A policy can be applied to multiple interfaces, but only one policy can be applied in one direction
(inbound or outbound) of an interface.
Follow these steps to apply the QoS policy to an interface:

The QoS policy applied to the outgoing traffic of an interface does not regulate local packets. Local
packets refer to the critical protocol packets sent by the local system for maintaining the normal
operation of the AP. To avoid drop of local packets, QoS does not process them. Commonly used local
packets are link maintenance packets and so on.
