    Hi,

    From what i can say the difference is mostly conceptual. With term "cir" you specify  a minimum guaranteed bandwidth which is relevant for a particular class of traffic. Without option "cir", value is commented as target rate to your class which is not minimum guaranteed bandwidth under a particular flow or set of flow. It is instead maximum bandwidth that class can sustain. So there shouldn't be any implication in traffic handling from device perspective at least on IOS device which i tested. However by using other policing schemes with oversubscription for example you could deal with pir which becomes target rate allowed for that class.
