Hi,
if I use frame-relay traffic-rate instead of frame-relay cir, I will get a
different result.
e.g
map-class frame-relay test
frame-relay traffic-rate 64000 96000
frame-relay adaptive-shaping becn
Spoke2#sh traffic-shape
Interface Se1
Access Target Byte Sustain Excess Interval Increment Adapt
VC List Rate Limit bits/int bits/int (ms) (bytes)
Active
211 64000 5000 64000 32000 125 1000 BECN
any idea why the byte limit is 5000 ? shouldn't it be 1500 ?
