  The only other thing I can think of is using traffic shapping and just
setting the average to the bandwidth requested. Using traffic shapping looks
like it does not set a burst interval does this sound like a viable solution
or am I missing something ?

R2#show policy-map interface e0/0
Ethernet0/0

  Service-policy output: QOS

    Class-map: PREC2 (match-all)
      0 packets, 0 bytes
      5 minute offered rate 0 bps, drop rate 0 bps
      Match: ip precedence 2
      Traffic Shaping
           Target/Average Byte Sustain Excess Interval Increment
             Rate Limit bits/int bits/int (ms) (bytes)
           128000/128000 1984 7936 7936 62 992
