• Binding — Combination of rules and actions that are bound to one or

Workflow to Perform QoS Mapping
To configure QoS mapping, perform the following:
1 If external DSCP values are different from those used on incoming
packets, map the external values to internal values in the DSCP Mapping
page.
2 Create ACLs, as described in "ACL and ACE " on page 261.
3 When ACLs are defined, create class maps and associate the ACLs with
them in the "Class Mapping " on page 236 pages
.
4 Create a policy map in the "Policy Class Maps " on page 240 pages, and
associate the policy map with one or more class maps. Specify the QoS
action, if needed, for example by assigning a policer to a class map, when
you associate the class map to the policy.
a
Single Policer — Create a policy that associates a class map with a
single policer in the "Policy Table " on page 239 pages and the "Policy
Class Maps " on page 240 pages. Within the policy, define the single
policer.
b
Aggregate Policer — Create a QoS action for each flow. This action
sends all matching frames to the same policer (aggregate policer),
defined in the "Aggregated Policer " on page 243 pages. Create a policy
that associates a class map with the aggregate policer in the "Policy
Table " on page 239 pages.
5 Bind the policy to an interface in the "Policy Binding " on page 242 pages
.
