I think it depends on what you are doing. I would bet this is a voice
configuration.
The time interval ratio is 100 and the cir and mincir is the same. In
this case you are trying to shape firm steady traffic flows. Note I'm
not sure the adaptive-shaping would affect anything. This is because
frame-relay adaptive-shaping will only back down the rate to the mincir.
Your CIR and MINCIR are the same. Thus, it wouldn't effect the rate
with adaptive-shaping turned on.
frame-relay cir 256000
frame-relay bc 2560
frame-relay be 600
frame-relay mincir 256000
no frame-relay adaptive-shaping
Here's a cut and paste of one of my emails. The numbers may not be 100%
correct, but they are close enough to be helpful to answer your
question.
----------------------------------------------------------
Maximum data transfer between two unequal frame-relay peers.
For example. Site One - T3 connection, Site Two - T1 connection with
256k cir.
Well, I know the maximum transfer would be the T1's port speed. I also
know that the minimum transfer would be the guaranteed 256k CIR. In
order to use the maximum transfer rate, I need to set Bc to (port
speed)/8. Normally I would double Bc to get Be, but Bc would be 193000,
and doubling it would be larger than the minicir value, so using my own
judgement I'll just reuse the Bc value for Be.
The beauty of these settings is if they are a bit too large, the
adaptive-shaping will drop the rates down closer to the minicir value.

Subject: No frame-relay adaptive shaping
Hi,
Found that whenever FR traffic shaping is used, the command "NO
frame-relay
adaptive shaping" is used in conjunction with other command, like the
following one:
map-class frame-relay voip
frame-relay cir 256000
frame-relay bc 2560
frame-relay be 600
frame-relay mincir 256000
no frame-relay adaptive-shaping
WHEN is the command needed ? and what does the command actually does ? I
couldn't understand till now.
Appreciate any reply.
Thanks
Yong
