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.
