Layer 3 managed switches

Managed 3 levels

— all managed switches have the ability to change individual operating parameters right during operation — this is how they differ from custom models, where such control is not available. Another difference is more extensive functionality. And the 3rd layer of the OSI network model, on which devices of this type operate, allows the use of the so-called logical routing — that is, to direct packets not to the physical MAC addresses of network devices, but to IP addresses assigned by the network. In fact, "switches" of this type combine the capabilities of classic switches with the functions of routers, which makes them extremely versatile, but significantly affects the price. The main scope of models of the 3rd level is professional telecommunication complexes, such as data centers.
