Applying the QoS policy
You can apply a QoS policy to different occasions:
Applied to an interface, the policy takes effect on the traffic sent or received on
the interface.
Applied to a user profile, the policy takes effect on the traffic sent or received by
the online users of the user profile.
Applying the QoS policy to an 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:

NOTE:
The QoS policy applied to the outgoing traffic of an interface does not regulate local packets.
Local packets are critical protocol packets sent by the local system for maintaining the operation
of the AC. To avoid drop of these packets, QoS does not process them. Commonly used local
packets include link maintenance packets, IS-IS packets, OSPF packets, RIP packets, BGP
packets, LDP packets, RSVP packets, and SSH packets.
