z Configure a QoS policy, that is, to configure the match criteria and a redirecting action for policy
routing.
z Apply the QoS policy, that is, to define the occasion to which the policy routing applies.
Configuring a QoS Policy
Follow these steps to configure traffic redirecting:

To implement policy routing successfully, ensure that the next hop address specified in the redirect
action exist and the outgoing interface is not a tunnel interface. If you fail to do that, the matching traffic
will be dropped.
Applying the QoS Policy
When configuring policy routing, you can apply a QoS policy to different occasions:
z Applied globally, the policy takes effect on the traffic sent or received on all ports.
z Applied to an interface, the policy takes effect on the traffic sent or received on the interface.
z Applied to a VLAN, the policy takes effect on the traffic sent or received on all ports in the VLAN.
