Generally, if you want to connect all network devices and client devices in a network, a Layer 2 switch is one of the basic devices that you need. As the diversity of network applications increases and the implementation of converged networks grows, new network switch , such as Layer 3 switch, are thriving in both data centers, complicated enterprise networks, commercial applications, and even advanced customer projects. Layer 2 vs Layer 3 Switch, what are their differences?
Switching technologies are crucial to network design , as they allow traffic to be sent only where it is needed in most cases, using fast, hardware-based methods.
Layer 2 vs Layer 3 Switch: Which One Do You Need?
What started out as a basic computer sending commands to another machine has evolved into an advanced computing sector covering a wide area of networks. Computer networks have emerged as a result of the convergence of computer and communication technology. And the influence of computer networks on communication networks resulted in something big, the result of which is network convergence. This ultimately gave rise to integrated system that is capable of transmitting all type of data and information. A networking bridge was required to connect multiple devices on a computer network.

The term Layer 2 is adopted from the Open System Interconnect OSI model, which is a reference model for explaining and describing network communications. Switches and bridges are mostly used for Layer 2 switching. They help to break up large size collision domain into separate smaller ones. They interconnect networks at layer 2, mostly at the MAC sub-layer, and operate as bridges. It builds tables for the transfer of frames among systems.

Overview of Layer 2 Networking. Understanding Layer 2 Broadcasting on Switches. Layer 2, also known as the Data Link Layer, is the second level in the seven-layer OSI reference model for network protocol design. Layer2 is the network layer used to transfer data between adjacent network nodes in a wide area network or between nodes on the same local area network. A frame is a protocol data unit, the smallest unit of bits on a Layer 2 network.
A MAC-level switch operates in. Layer 2 of the OSI Model and can also operate in a combination of. Layers 2 and 3. IP-level switches operate in Layer 3, Layer 4.
Layer 2 Switch vs Layer 3 Switch
It means that packets can be forwarded without any noticeable delay. Everything that I explain about the multilayer switches from now on also applies to routers. You know that layer 2 switches only will switch Ethernet frames within a VLAN, and if we want we can filter traffic based on layer 2 for example with port-security. The multilayer switch can do the same but is also able to route between VLANS and filter on layer 3 or 4 using access-lists. Forwarding on layer 2 is based on the destination MAC address.
Prerequisite — Network Devices A switch is a device which sends a data packet in a local network. What is advantage over hub? A hub floods the network with the packet and only destination system receives that packet while others just drop due to which the traffic increases a lot. To solve this problem switch came into the picture.

- Гамма-лучи против электромагнитной пульсации. Распадающиеся материалы и нераспадающиеся. Есть целые числа, но есть и подсчет в процентах. Это полная каша. - Это где-то здесь, - твердо сказала Сьюзан.
В центре помещения из пола торчала, подобно носу исполинской торпеды, верхняя часть машины, ради которой было возведено все здание. Ее черный лоснящийся верх поднимался на двадцать три фута, а сама она уходила далеко вниз, под пол.
