Leigh,
NO, this means that your cir is 4mb. The BC and BE is what will be sent
should you build up any credit and the isp will agree to send the extra.
The BC and BE are on top of your cir.
Similar to Frame.
Regards
Lee.

Subject: Re: Rate-Limit - I just don't get it !!
To clarify,
I do get it a bit.
My understanding is that:-
Burst means "in chunks of"
i.e
rate-limit 4000000 500000 600000 conform transmit exceed drop
Does this mean "you can send you data up to 4 meg a second in chunks of
up to 500k, but no more than 600k"
If so - what's the point of the 600k ?!
