I tried to limit the connection speed of the client through policing but with no success. Tried document "Quality of Service: Policies Aggregation" with no success too.
For example, tried the following:
class-map match-all BestEffort match any ! policy-map aggregate-member-link class BestEffort service-fragment BE shape average 100000000 policy-map subscriber class class-default fragment BE shape average 100000000
