You didn't spesify what you want to do, but I assume you want to sell f.ex.
subrate ethernet and still protect ie. VoIP. Try something like this:
class-map match-any LLQ
match <criteria>
polcy-map 256k
class class-default
shape avarage 25600
service-policy priority
policy-map priority
class LLQ
priority percent 40
class class-default
fair-queue
random-detect
interface PIM
service-policy output 256k
First you define parent which does nothing else but shapes the speed
and calls sub/child policy for all and every packet. Then use subpolicy
normally. If you're using serial or ATM remember to adjust tx-ring
accordingly, so that you can serialize tx-ring full of bulk traffic in worst
case scenario without unacceptable delay to priority traffic.
Hope this helps,
