Brian, thanks for the reply.
Here is what I did on R4, use CIR=6000, because it will take about 2
seconds to get a 1500 byte ping across:
int s 0/0
 frame traffic-shaping
 frame class other
 frame inter 402
  class dlci402
map-class frame dlci402
 frame cir 6000
 frame bc 750
map-class frame other
 frame cir 192000
 frame bc 24000
And then observe:
Rack1R4#sho traffic-shape

Interface Se0/0
       Access Target Byte Sustain Excess Interval Increment Adapt
VC List Rate Limit bits/int bits/int (ms) (bytes)
Active
402 6000 93 750 0 125 93 -
403 192000 3000 24000 0 125 3000 -
405 192000 3000 24000 0 125 3000 -

Pinging through R4 (from R5):
Rack1R5#ping 132.1.0.2 size 1500 repeat 20 timeout 3
Sending 20, 1500-byte ICMP Echos to 132.1.0.2, timeout is 3 seconds:
!!!!!!!!!!!!!!!!!!!!
Success rate is 100 percent (20/20), round-trip min/avg/max = 44/1933/2128
ms

I noticed the average time is right at 2 second (minus the first packet
which doesn't appear to be shaped).
