A switch is a device responsible to send a data packet within a local network. Layer 2 and layer 3 switches primarily differ in the routing function. Basically, a layer 2 switch only functions with MAC addresses and does not look after IP addresses or any components of higher layers. On the other hand, a layer 3 switch accomplishes everything that a layer 2 switch does and also supports additional static routing and dynamic routing. It implies that layer 3 switch has both MAC address table and IP routing table.
Layer 3 switches can flawlessly deal with intra-VLAN communication and packets routing amongst various VLANs. Go through the following selection to pick up the best layer 3 switch in 2023 matching your requirements.

Pros And Cons
What Is Layer 3 Switch?
In simple terms, layer 3 switches operate on layer 3 of OSI model (network layer) where they route the packet through an IP address. It accomplishes the static routing to transfer data amongst various VLANs. The dynamic routing method allows the switch to perform optimal packet routing. A network with a layer 3 switch is provided with a set of multiple paths as per the real-time scenario of the network to transmit the data packets.
How To Pick The Best Layer 3 Switch?
1. Number of ports
For connecting a huge number of devices and end-users, it is better to choose a layer 3 switch with a high port density. Firstly, you need to device how many devices are needed to connect to the access layer. Subsequently, you need to determine how many switch port numbers you would require for the access layer. Many of the top-notch layer 3 switches support port density up to 48.
2. Port speed
The majority of access switches including the best layer 3 switch are equipped with 10/100/1000Mbps ports. The choice between Gigabit Ethernet or Fast Ethernet depends on the explicit requirements of your network.
Fast Ethernet is adequate for data traffic and IP telephony on the majority of small to medium enterprise networks, but its performance is significantly lower than Gigabit switches. Furthermore, it is quite important to select high-bandwidth uplink ports when the uplink port is oversubscribed due to the required bandwidth being higher than the accessible maximum bandwidth to distribution layer switches. Hence, it is recommended to choose a layer 3 switch with high port density and fast port speed.
A high-speed network is not the only requirement. It should operate safely. Therefore, before choosing a layer 3 switch, you need to check what safety features are implemented. Many of the best layer 3 switches come with safety features like DoS protection, source guard, and other techniques to avoid security attacks.
You may find many of these switches equipped with a complete security protection mechanism that streamlines maintenance and management. Lightning protection is available on some of these switches to avoid lightning strike induction currents and power spikes.
With time, the number of users in an enterprise network alters. Hence, it is crucial to think about the number of users the network would require in the future. Make sure the layer 3 switch you choose boasts the network design required to fulfill the requirement for the enterprise environments in the upcoming 3-5 years. This ensures that your chosen switch can offer the opportunity to smoothly upgrade the network.
Another key aspect that influences the buying decision for a layer 3 switch is the cost. If you intend to purchase a layer 3 switch designed with fiber optic ports instead of RJ45 ports then you have to consider the expense of optical modules.
FAQs When Picking The Best Layer 3 Switch
1. When to choose a layer 2 switch and when to choose a layer 3 switch?
If there is a pure layer 2 domain then a layer 2 switch is recommended. A pure layer 2 domain is the one where the hosts are connected. It is typically known as the access layer in a network topology.
You will need a layer 3 switch if you want to aggregate multiple access switches and perform inter-VLAN routing. Layer 3 is alternatively known as the distribution layer in the network topology.
2. What are the significant differences between Layer 2 and Layer 3 switches?
The key difference is the routing method. Layer 3 switches are competent in inter-VLAN routing and don’t require additional devices connected such as router-on-a-stick. Because network architectures on layer 2 switching permit end station connectivity, it is better to build a VLAN through the layer 2 switch only. Also, it provides easy, affordable, and high-performance connectivity for plenty of end stations. Layer 3 switches have also sustained a presence at several points in a corporate network.
3. In what cases do you need a Layer 3 switch?
If you have VLANs or planning to include them in the future then you will need a layer 3 switch. If individual departments require separate broadcast domains for performance and security then you will need a layer 3 switch. This type of switch is required if you have subnets connected through a router. In case when your network has 250+ devices connected to the same VLAN, you will need one of the best layer 3 switches.
4. Do layer 3 switches only perform routing?
In addition to routing packets, these switches also support functions that require understanding the IP address information of data that is entering the switch like tagging VLAN traffic depending on IP address rather than manually configuring a port.
These layer 3 switches can work as both routers and switches. In VLANs, they provide you with multiple options to efficiently manage your bandwidth. These switches are implemented with scalable and powerful technology for building high-performance Ethernets. When it comes to enhancing your network performance, you can choose the best layer 3 switch from the above selection. These switches ensure high-speed networking and excellent network safety.
