Re: QOS: police rate ???

Yes, but what happens when police rate is applied on physical interface ? Is
it the same as police cir ?

In my lab:
R1----(F0/0)R2(F0/1)----R3

On R2 there are two policy-maps to limit icmp to 1%:

policy-map TEST0
 class TEST0
  police cir percent 1
    conform-action transmit
    exceed-action drop

policy-map TEST1
 class TEST1
  police rate percent 1
    conform-action transmit
    exceed-action drop

TEST0 is applied on input of F0/0
TEST1 is applied on input of F0/1

Now, when I ping R3 from R1 and R1 from R3 results are excactly the same.
Are then "police cir percent" and "police rate percent" THE SAME ? My test
tells me that they behave the same way, is there a difference in the way
they work inside the router or even not that ?
