Koen,
Can you explain better why with need to multiply with 1.5 ? I thouth there were some recommendations from cisco about the normal burst and max burst which have something to do with this 1.5 but can't remember well what was it about.
I am for solution 2.
Best,
Nick

if the b is lowercaps its bits so you should divide by 8. That give's you
the burst size per timing interval. Not per second. So you have to convert
the bps to a byte per timing interval value. I believe the timing
interface for CAR is 1,5. So that makes 300000/8*1,5=56250.
-> solution 3.
Don't forget the "exceed-action drop".

|
| Sol 2 :rate-limit output 8000000 18750 37500 conform-action
| set-prec-transmit 5
|
| 150000/8 = 18750
| 300000/8 = 37500
|
| Sol 3 :rate-limit output 8000000 28125 56250 conform-action

|
| (150000/8)*1.5 = 28125
| (300000/8)*1.5 = 56250

|
| Then the second figure is Normal burst which is number of Bytes.
|
| Then the third value is the Maximum Burst which is number of Bytes.

|
| is my config rite ? the confision is in normal n max is it in bytes or
| bits...somebody please lead me out...
