correct me if I'm wrong... I configure this and test the below configs.
If I have the normal burst at 8000 and excess burst at 8000 my traffic was
much below the 56k. When I configured the excess burst to 16000 it was
closer to 56k. which lead me to think that since traffic is not a constant
stream, bursty by nature, you need to have room for excess burst. But I
know in the documentation there is a example with normal burst of 8000 and
excess burst of 8000 which did not work for me.
-----------------64k (excess burst)
|8000
-----------------56k (normal burst) this is the limit which the config
will limit the access rate.
|8000
-----------------48k
48k+8k=56k, 48+16k=64k

Can you tell us how you calculate bps, burst-normal and burst-max? I know
sometimes these numbers are given, but if you take the 56k circuit as an
example, if burst-normal is 8000 bytes, isn't that exceeded 56k bps already?
