When implementing traffic shaping on a 100mb ethernet interface, the traffic-shape command has the following associated paramaters
router(config-if)#traffic-shape rate ?
<8000-100000000> Target Bit Rate (bits per second)
The upper limit seems to be 100000000 ie. (1 billion bits) which equates to 100000000/8 = 12500000 bytes ie. 12.5 Mb if my maths is correct!!.
Is this 12.5 mb limit correct and how would a limit of 20mb for traffic shaping be imposed on a fast ethernet interface?
thanks!

100000000 - is actually 100 Million bits per second or 100 Mbps which is the speed of the fast ethernet. If you have traffic with rates of 20 MBps (B -> bytes) which is 160 Mbps so that would be above the fast ethernet interface speed itself.

traffic-shape will do up to 97.7 Mbps, not 12.5 Mbps.
If 1,024,000 bps = I Mbps
then
100,000,000 bps / 1,024,000 = 97.65625 Mbps
So the traffic shaping will almost do 100 Mbps
