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 .
