A network ahead and change filters in a device layer of the OSI data communication between the ports 2 datagrams (block) () in packets based on MAC addresses to connect the cables. [6] This is different than an input port just forward all ports connected to the appropriate packages instead contact. Obviously, the IP address (OSI Layer 3) that a network for communication between the LAN segments or large or complex state routing traffic based on the necessary, but will be a transition. Some switches based on IP addresses is a marketing term orientation as a talented, but still passed. Normally this switch, most or all of the network directly connected to a switch to another switch or delivery, depending on the transition has a large number of ports. [7]

Switches, routers and bridges, and distribute the traffic load or application content (eg a Web URL identifier) devices is a marketing term. Switches one or more (that is, from beginning to end) physical, data link, network or transport layers, including the OSI model, can operate. Multiple layers of activity at the same time that a device called a multi-layer switch.

Bad “key” is defined in terms that try to understand the first network Overemphasizing often leads to confusion. Many experienced network designers and operators, equipment not related to only one protocol level, each with a logic that are covered by OSI recommended starting. Multilayer device selection by the selection of the applications in question could lead to an advanced topic, but it is not only a multi-layer switching, real-world design concept.
