QoS Policing with and withour CIR keyword

ashse

Brothers,

please help me understand the difference between QoS Policing with and withour CIR keyword. Below are examples:

 

With CIR keyword:

policy-map policy1

class one_rate_2_color_policer

police cir 256000 conform transmit violate drop

source:

wo CIR keyword:

policy-map parent 
   class class-default 
     police 3300000 103000 103000 conform-action transmit exceed-action drop

I don't think there is any difference - take a look at the command reference -

I think using CIR aides readability!
