Bc is always CIR/32 or 1500 bytes (if CIR/32 is lower than 1500
bytes). Be is always 2x Bc. I hope this helps.
Sincerely,
Dennis Hartmann

Subject: Byte Limit on CB Shaping
Do you know how to configure Be when using CB Shaping?
On the following example I did not specified it, and it defaults to 9600
(Wendell's DQoS indicates that too)
As the Byte Limit showed is Bc + Be (2400), I am considering it is really
using Be. (which would be the same with GTS, that shows Be = Bc and byte
limit equaus Be/8 + Bc/8).
Would you agree?
