Typically ,youwouldusetheDiffservcommandsettocompleteconfigurationtasksinthe
followingorder:
1. EnableDiffServ.
2. CreateaClass.
3. CreateoneormoreclassificationruleswithintheClass.
4. CreateaPolicy.
5. AddoneormoreClassestothePolicy.
6. AddPolicing(Conforming/Non‐conforming,Drop/Forward,RateLimit,Precedence/DSCP
Rewrite)actionsorjustMarking

7. AssignthePolicytooneormoreports.
