This is the difficult way to do this -- CAR is the easiest solution. For
your rate policy (that's the first number), simply define the bandwidth of
the interface. normal and excess bursts won't matter, because all traffic
will meet the "conform-action" and you can just set the
"exceed-action" the same as the conform-action (just to be safe). The
conform action should be a set-prec-trans <ip precedence value>
