I see what you mean so GTS would not be good here either and I do not see a
way to set the be value to 0
R2(config-pmap-c)#shape average 128000 ?
<256-154400000> bits per interval, sustained. Needs to be multiple of
128.
Recommend not to configure it, the algorithm will find
out
the best value
<cr>
R2(config-pmap-c)#
