I believe you have to use the command "frame-relay traffic-shaping" to use
map-class frame-relay. You do not have to use "frame-relay traffic-shaping"
when using "frame-relay de-group"
I don't think of sending a packet with the DE bit set as traffic shaping.
It is just a way of hedging your bet. In other words you know it will get
killed first when congestion occurs. But if all of the DEs are killed then
the only packets left are the choice of the switch to kill. Then you have
lost control. So the answer to your question is no, they are not both FRTS.
At least not how it appears to me.

okies with the minCIR . that field should not be in the manual PVC as there
is nothing to do with it.
But tell me that is my understand correct that u can do FRTS in 2 ways, one
automatic (becn) and other manual (DE).
I know the best solution is becn as it is will automatically throtal the
bandwidth and comes again to its normal after sometime.
note : Manual and Automatic are my given name to becn and DE respectively.
