The 3550 was the first multilayer switch offered at its price point to boast such a vast array of features. It was later succeeded by the 3560. The 3750 is a more powerful switch that introduced, among other things, a true stacking feature, which the 3560 lacks. There is not enough room to cover all of the capabilities of the 3750 in one chapter, SO I've fo
