Workflow to Configure Advanced QoS Mode

To configure Advanced QoS mode, perform the following:

  1. Select Advanced mode for the system by using the QoS Properties page. Select the Trust Mode using the Global Settings page. If a packet CoS level and DSCP tag are mapped to separate queues, the Trust mode determines the queue to which the packet is assigned:
    • If internal DSCP values are different from those used on incoming packets, map the external values to internal values by using the Out-of-Profile DSCP Mapping page. This in turn opens the DSCP Remarking page.
  2. Create ACLs, as described in Create ACL Workflow.
  3. If ACLs were defined, create class maps and associate the ACLs with them by using the Class Mapping page.
  4. Create a policy using the Policy Table page, and associate the policy with one or more class maps using the Policy Class Map page. You can also specify the QoS, if needed, by assigning a policer to a class map when you associate the class map to the policy.
    • Single Policer--Create a policy that associates a class map with a single policer by using the Policy Table page and the Class Mapping page. Within the policy, define the single policer.
    • Aggregate Policer--Create a QoS action for each flow that sends all matching frames to the same policer (aggregate policer) by using the Aggregate Policer page. Create a policy that associates a class map with the aggregate policer by using the Policy Table page.
  5. Bind the policy to an interface by using the Policy Binding page.
