Configuring CoS on Provider Switches of an MPLS Network

You can add class-of-service (CoS) components to your MPLS networks on EX Series switches to achieve end-to-end Differentiated Services to match your specific business requirements. The configuration of CoS components on the provider switches is the same regardless of whether the provider edge (PE) switches are using MPLS over CCC or IP over MPLS.

This task shows how to configure a custom EXP classifier and custom EXP rewrite rule on the provider switch.

  1. Import the default EXP classifier classes to the custom EXP classifier that you are creating:
  2. Add the expedited-forwarding class to this custom EXP classifier, specifying a loss priority and code point:
  3. Specify the values for the custom EXP rewrite rule, e1:

You can also configure schedulers and shapers as needed. See Defining CoS Schedulers and Scheduler Maps (CLI Procedure).
