A switch is a critical component in your network infrastructure. It is the backbone of your Local Area Network (LAN) and a critical piece of hardware that connects all devices within your network.
It efficiently redirects and forwards data to ensure it reaches the correct destination. For businesses, having the right network switch is essential for meeting your operational needs and maintaining connectivity.
Network switches vary in size and can have anywhere from a few ports to as many as 52. However, the key differences lie in the types of switches available: managed switches and unmanaged switches.
When choosing the right type of switch for your network, one important factor to consider is whether to use a managed or unmanaged switch. The main difference between these is the level of control you have over the switch’s settings.
What is a Network Switch?
So, what is a switch? Simply put, a network switch is hardware that allows communication between two or more devices, such as computers or laptops. By connecting multiple devices, it creates a network for communication that will enable the sharing of resources such as printers, servers, file storage, and internet access.
Devices exchange information by sending and receiving “packets” of data across the network. Basic switches function by forwarding these packets from one device to another.
Network switches can exist as standalone applications or as integrated components within other equipment, such as network routers and wireless access points (APs), which also perform functions related to data packet handling. Basic switching technology has been a foundational element of networks for decades and remains essential to the infrastructure of modern networks, including the Internet.
Managed Vs Unmanaged Switch?
Now you know what a switch does, how do you choose between a managed or unmanaged switch? Unmanaged switches are simple plug-and-play devices that require little to no configuration, making them suitable for small networks with basic needs. On the other hand, managed switches offer complete customisation and control, allowing you to configure settings and monitor network performance. These features make managed switches ideal for more extensive networks or those supporting critical functions where performance, network security, and flexibility are essential.
An unmanaged switch is a straightforward device that connects ethernet devices with a fixed configuration. It is ideal for small networks or temporary setups within a more extensive network. Its simplicity means no customisation options are available, which can be beneficial if your network needs are not complex.
In contrast, a managed switch provides a higher level of control, allowing you to manage, configure, and monitor your Local Area Network (LAN) settings. With a managed switch, you can regulate LAN traffic, prioritise specific channels, and create virtual LANs (VLANs) and subnets to segregate groups of devices for better traffic management. These switches also have redundancy features that ensure data duplication and recovery in case of device or network failures.
One significant advantage of a managed switch is its ability to prioritise channels dynamically, ensuring optimal performance where it matters most. Features like Priority SNMP facilitate remote troubleshooting, enabling you to identify and address any performance issues that may arise quickly.
Security Considerations
Unmanaged switches typically offer basic network security management. Their security relies on minimising vulnerabilities between systems, often enhanced by accessories like lockable port covers to prevent unauthorised physical access.
Managed switches, on the other hand, provide robust security benefits. They allow for comprehensive network monitoring and control, enabling you to respond effectively to active threats. Key security features vary by model but often include network communication encryption, access control, and VLANs for creating temporary or limited access for specific users.
However, it’s essential to understand that the extensive control offered by managed switches can also pose security risks if not carried out correctly. Therefore, it’s necessary to monitor and manage these devices carefully with the help of expert teams like Performance Networks. We can implement controls such as various access privilege levels to mitigate potential threats.
Managed switches are ideally suited for enterprise-sized businesses with many network requirements. These switches provide the necessary features to manage and optimise data flow efficiently, making them essential for larger businesses prioritising performance and reliability.
How Do I Choose Between a Managed and Unmanaged Network Switch?
Choosing between a managed and unmanaged network switch isn’t a decision on preference alone. A primary unmanaged switch is often sufficient for smaller businesses operating from a single office or for freelance professionals. However, for more extensive networks with many different users all accessing resources, managed switches become essential.
It’s important to consider the size of your network and the specific features and complexity it requires. Security is a significant factor in this decision. Even if your network is relatively small, handling sensitive data such as customer information or financial details may necessitate a managed switch for better security control.
Additionally, if your business needs a guest network for users who require temporary, limited access, the VLAN capabilities of a managed switch can help maintain security while facilitating that access. Ultimately, evaluating your unique needs will guide you to the right choice.
