The term “Layer 2” is being accepted from the Open System Interconnect (OSI) model (a reference model used for describing network communications). It denotes the procedure of using MAC addresses and devices over a LAN to segment a network. The layer 2 switch interconnects network at Layer 2, usually at the MAC sub-layer, and functions as bridges.

Layer 2 switches are responsible for switching and transferring data to the MAC address of every network node. Compared to routers, layer 2 ethernet switches are faster because they don’t need much time for the assessment of the network layer header information. Furthermore, this layer transfers data between neighboring network nodes in a WAN or amongst nodes on a similar LAN segment. If your network requires layer 2 switching then you can fulfill that need by choosing the best layer 2 switch from the following selection.

How To Pick The Best Layer 2 Switch?

End up with the best layer 2 switch conforming to your needs with the assistance of the following key factors.

1. Number of switch ports

Before choosing any network switch, one of the most vital aspects to consider is the inclusion of the right number of ports. A Layer 2 switch with an inadequate number of ports will be useless. For instance, if there are 4 devices to be connected then you need to look for a Layer 2 switch with at least 5 ports. Try to choose the one with more ports because the additional ports will work as backup ports for unforeseeable crashes. Conversely, the inclusion of a few extra ports helps you to add other devices to the network in the future.

2. PoE support

PoE (Power over Ethernet) technology essential relates to a system that transmits power accompanied by network data on an Ethernet cable. Using this technology decreases costs because you don’t have to install any additional power cord. With exceptional safety, your devices stay protected from low or high voltage.

Certainly, PoE support is a benefit but Layer 2 switches with PoE support are more expensive. Hence, if you can afford the high price then it is recommended to buy a Layer 2 switch with PoE support.

3. Safety features

For safe data transmission and overall safe operation, look for a Layer 2 switch with safety features. You may find overload current protection in many of the best and reliable Layer 2 switches. This safety feature makes sure that even though the network is subjected to excess current, it stays protected. Moreover, a grounding point is available in some Layer 2 switches. It defends equipment against external electrical surges

Layer 2 Switch VS Layer 3 Switch

Layer 2Layer 3
Switching packets are rerouted from the source to the destination portSwitches take some time to assess data packets before discovering the best available route to transmit data packets to the destination port
Uses the Address Resolution Protocol (ARP) to discover MAC addresses of other devicesUses IP addresses for routing in the Virtual LANs (VLANs)
Used to decrease traffic on the local networkTypically used to implement VLAN
Only performs switching by discovering and maintaining a table of MAC addressesAlong with discovering and maintaining a table of MAC addresses, Layer 3 switches facilitate routing of data packets via IP addresses
Has some tendency of switching packets from one port to anotherAlso assists devices to communicate outside the networks

FAQs When Picking The Best Layer 2 Switch

1. What are the benefits of using a Layer 2 switch?

The best layer 2 switch assists to forward packets depending on unique MAC addresses. You can rapidly deploy it at a reduced cost. Improved security and low latency are also prominent benefits.

2. What are the disadvantages of using Layer 3 switches?

Usually, the expense of the L3 switches is significantly high when compared to the Layer 2 switch. These switches don’t offer WAN functionality. Also, they lack virtualization and multiple tenants.

3. What it means by Layer 2 devices?

The Layer 2 network devices utilized on a Layer 2 Ethernet network contain network interface cards, bridges, hubs, and switches. These Ethernet devices utilize “burned in” MAC addresses to recognize each host.

4. Why is a Layer 2 switch used?

A Layer 2 switch is chiefly accountable for transmitting data over a physical layer. It carries out an error check on every transmitted and received frame. Furthermore, it flawlessly transmits data because it just needs the MAC address of NIC on every network node.

5. From Layer 2 devices and Layer 3 switches, which one should you use?

A Layer 2 domain is the one in which the hosts are connected. Hence, in that case, a Layer 2 switch works well. Usually, it is known as the access layer in a network topology. But if you want the switch to combine multiple access switches as well as perform inter-VLAN routing, then you should use a Layer 3 switch.

Final Thoughts

When it comes to segmenting a network, layer 2 switches are useful. They help forward packets depending on the unique MAC addresses. For efficient data packet transmission and reduction of traffic on the local network, it is recommended to choose the best layer 2 switch. These switches carry out the switching function to re-arrange the data frames from the source to the destination network. One of the finest attributes is that these switches detect or correct errors encountered in the physical layer.
