"traffic-shape rate" command

Hi All,

You can configure generic traffic shaping using the following interface
level command:

traffic-shape rate bit-rate [burst-size [excess-burst-size]]
[buffer-limit]

I have two questions regarding this command. First, you can configure
many "burst-size" (Bc) that would achieve the same target bit rate. The
point is that when you change the value of the "burst-size", the
internal time interval will change accordingly to achieve the configured
target bit rate. If this is the case, what benefit I could get from
changing the value of the "burst-size". I could simply leave it
untouched and let the router calculates its value.

The second question, how does the "buffer-limit" parameter affect the
performance of the traffic shaping?

Could anyone clarify these two points?
