Network switches are a critical part of any industrial network. Switches provide the ability for devices to communicate with each other, and when traffic is routed through them, it ensures smooth operation. But there are two main types of switches that are used in industrial networks: Layer 2 (L2) and Layer 3 (L3). Both types of switches perform different functions, so it’s important to have a basic understanding of the differences between them before selecting one for your network. In this blog post, we’ll discuss what you need to know about L2 and L3 switches, their uses, and which one is best for your industrial network needs.
What is a layer 2 switch?
Layer 2 switches are devices that provide interconnection between network segments at the data link layer of the OSI model. A layer 2 switch reads incoming Ethernet frames and forwards them based on each frame’s destination Media Access Control (MAC) address. Layer 2 switches can also filter traffic, deliver traffic to specific ports, or perform other functions based on the device’s configuration.
What is a layer 3 switch?
A layer 3 switch is a specialized hardware device used to connect computers and other devices on a network. It operates at the third layer of the OSI model, the network layer, and can therefore be used to route traffic between devices on different subnets. A layer 3 switch is also sometimes known as a multilayer switch.
The pros and cons of each type of switch
There are two types of industrial network switches: Layer 2 vs Layer 3. Here are the pros and cons of each type:
Layer 2 switches:
PROS:
– Cheaper than Layer 3 switches
– Easy to set up and configure
– Great for small networks
CONS:
– Limited features and flexibility
– Not suitable for large or complex networks
Layer 3 switches:
PROS:
– More expensive than Layer 2 switches but offer more features and flexibility
– Suitable for large or complex networks
CONS:
– More difficult to set up and configure
How to choose the right type of switch for your needs
Choosing the right type of switch for your needs is important to ensure that your network functions properly. There are two main types of switches: Layer 2 and Layer 3.
Layer 2 switches are use to connect devices on the same network. They work by forwarding traffic based on the MAC address of the devices. This type of switch is typically use in small networks.
Layer 3 switches are use to connect devices on different networks. They work by forwarding traffic based on the IP address of the devices. This type of switch is typically use in large networks.
Conclusion
However, Layer 2 and Layer 3 switches provide different functions to meet the needs of industrial network users. The features, specifications, and pricing vary depending on the type of switch you choose. We hope this article has helped shed some light on the differences between these two types of industrial network switches so that you can make an informed decision about what is best for your specific application or environment. With a clear understanding of your needs, you can choose the right hardware to get your job done efficiently and effectively.
