Workflow to Configure Advanced QoS Mode
To configure Advanced QoS mode, perform the following:
1
Select Advanced mode for the system in the QoS Mode page .
2 If external DSCP values are different from those used on incoming
packets, map the external values to internal values in the
DSCP Rewrite
page.
3 Create ACLs, as described in ACLs.
4 When ACLs are defined, create class maps and associate the ACLs with
them in the
Class Mapping pages .
5 Create a policy map in the Policy Class Maps 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 pages and the Class Mapping 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
Aggregate Policer pages. Create a policy that associates
a class map with the aggregate policer in the
Policy Table pages.
6 Bind the policy to an interface in the Policy Binding pages .
