A Network Switch Is Like A Network Bridge But With More Ports That Use MAC Addresses To Transfer Data In Layer 2 Or The OSI Data Link. 

Layer 2 Switch defines the switch, the types of switches and their differences and introduces the best switches available for medium and large networks.

In selecting the products of this list, we have tried to introduce the best and most efficient Layer 2 switches on the market, which, along with the high quality of the products, has also brought with it user satisfaction.

What is a switch?

A network switch is a hardware that connects different devices (such as IP cameras, computers, and even other switches) to share resources and communicate. The switch receives packets and directs them to their destination on the LAN. In the past, hubs used to connect network devices. But hobbies had many drawbacks. To fix them, bridges creating. They were better than hubs because they created multiple collision domains but had a limited number of ports. Eventually, switches were created and are still widely used. Switches have more ports than bridges, and they can monitor incoming traffic and make frame transfer decisions accordingly. Also, each port on a switch is a separate collision range, and no collisions occur.

Switches are commonly used in large environments and for professional applications. But over time, as the use of surveillance and security cameras expanded, so did the need for switches for home networks. So today, switches have many different uses and are used by many users around the world.

Layer 2 switches only do the switching work and are required to transfer data to the MAC address of each network node. Layer 3 switches, on the other hand, can route packets using IP addresses.

Types of network switches and features that you should pay attention to before preparing the switch:

Unmanaged switches

Unmanaged switches do not need to be configured and managed and act as plug and play devices (connect your devices one by one using Ethernet cables). Everything in these switches is done automatically. In fact, these switches have a fixed configuration and do not allow this configuration to be changed. They can be placed on a table or mounted on a rack. Unmanaged switches are mostly used to connect devices to the edge of the network or in a small independent network with several components. They are usually lower priced and do not look different from management switches. Some of them can control locally via LED indicators.

Smart web switches

Web smart switches are management switches, but they offer a more limited set of features. Smart switches are easy to set up and provide a web interface to configure many features. Smart switches do not have any console port, SSH or Telnet.

 Management switches

Management switches also have many configurable features that offer the highest management and control of the previous two types. These switches can manage via a web interface, console port, SSH and Telnet.

Number of switch ports

One of the most important factors to consider is choosing a switch with the right number of ports. For example, if you have 4 devices to connect to, a 5 or 8 port switch will meet your needs. Keep in mind that several ports should be considered as backup ports for possible crashes in the future. On the other hand, you may add other devices to your network in the future and need more ports.

Fast Ethernet is a term that refers to 100 Mbps Ethernet speed, while Gigabit Ethernet means 1000 Mbps.
Obviously, a Gigabit switch is better, but it may not really be necessary, depending on your network settings. Ideal if you need to transfer large amounts of data and have fast low-latency networks.

PoE support

PoE (Power over Ethernet) technology refers to any system that transmits power along with network data over an Ethernet cable. This technology helps reduce costs (no need to install an extra power cord), is safe (protects your devices from high or low voltage), and is flexible. (Compatible devices can install anywhere without the worry of having a power outlet nearby.)
PoE support is obviously an advantage, but these types of switches are more expensive. So, if cost is not an issue for you, buying a PoE switch can be a smart choice.

Recommended switches, desktop or wall switches

Ideally, a switch can install in all three shapes. Recount switches are typically designed for professional and rack-mounted environments, such as data centres. Desktop switches can be installed on all smooth surfaces and have more variety in the market. Wall switches also have kits for wall mounting.
