I have looked high and low for other training materials on the configuration of the Centillion switch but with no luck. Does anyone have the study material for the Global Knowledge course: ATM II: Configuration and Implementation [formerly ATM Internetworking]? Nortel says this is the only source for this material. Taking the class is not monetarily feasible. If you have this item and would be willing to sell or loan it to me, contact me at sandra.carr1@jsc.nasa.gov.
