CCLs are set according to the classification defined in the ACL, and they cannot be
defined until a valid ACL is defined. When CCLs are defined, ACLs and CCLs can
be grouped together in a more complex structure, called policies. Policies can be
applied to an interface. Policy ACLs/CCLs are applied in the sequence they
appear within the policy. Only a single policy can be attached to a port.
In advanced QoS mode, ACLs can be applied directly to an interface. However, a
policy and ACL cannot be simultaneously applied to an interface.
After assigning packets to a specific queue, services such as configuring output
queues for the scheduling scheme, or configuring output shaping for burst size,
CIR, or CbS per interface or per queue, can be applied.

(DSCP) values from incoming packets to DSCP values in outgoing packets. The
DSCP values can be modified only within the queue range. This information is
important when traffic exceeds user-defined limits.
To map DSCP values:
