Hello
Thanks for the reply
I have done a few tests, and i could only get the
DE-bit to be marked when i set the Be value. I belive
since be=0 by default , then the trafic will never go
above the desired traffic-shaped rate, unless an
excess burst is specified
Im still confused though. If the CIR is 64kbps and the
bc = 8k, and i set the be to something greater than 0,
does that mean that anything over 72kbps in a single
burst is marked with a de-bit ( since 64+8= 72) ? or
is anything over the CIR ( 64k ) set with the de-bit.
Furthermore, if i set the be , to lets say 1k, does
that mean that anything over 73k is dropped since
nothing can placed in the token bucket for FRTS
As you can see, im very confused.
Brians, Scott , any thoughts on this
Thanks
