If it were real life, and you really had more than 128k traffic to send, you would find yourself with output drops on the interface as your rules attempted to cram more bits into the line than were physically possible. Don't break the laws of physics, it's not cool.. :) HTH, Scott

What if my physical clock rate is 128K and I configure: shape peak 80000 The max rate then would be: configure rate x (1 + Be/Bc) = 80,000 x 2 = 160,000 But I guess that the actual max rate will be dictated by the physical clock rate! So in in this it can't be over 128K. Is that correct? Scott Morris <[EMAIL PROTECTED]> wrote: It's not the "normal" way of looking at it, but you could certainly use the "shape peak" feature within MQC to achieve that goal. While the main focus is to shape, it will also provide a "do not exceed" value that serves kind of as a limit!

He gave me a scenario that states that he has to limit all IP Precedence 3 traffic out of an interface to 256k, but he cannot use policing or rate-limiting. My answer was to use shaping. But from my experience, doesn't the word "limit" negates that as a possible answer? Even though you can use shaping to limit, I was always under the impression when studying for the CCIE that if they use the word limit that means no shaping. Can someone help ease my conscience? _____ Be a better friend, newshound, and know-it-all with Yahoo! Mobile.
