Managed switches are network devices that allow users to have advanced configuration and control over their network. They come with a user interface, often in the form of a web panel or application, enabling users to manage network settings. These switches offer a wide range of functions, including bandwidth monitoring, traffic control, VLAN configuration, traffic prioritization, MAC address blocking, and network troubleshooting capabilities. Managed switches are commonly used in medium to large networks where flexibility and full control over the network infrastructure are required. Their advantages include the ability to tailor the network to specific needs, better bandwidth management, and increased control over data traffic.
Managed switches come in various types, including Layer 2 and Layer 3 switches, as well as modular and stackable switches. Layer 2 switches manage the network at the MAC address level, while Layer 3 switches operate at the IP address level. Modular switches allow for flexible scaling and network expansion, while stackable switches enable multiple switches to be connected into one larger network.
Several brands and manufacturers produce managed switches, including Cisco, HP, Dell, Netgear, and TP-Link. Each brand offers managed switches with different features, parameters, and prices. Before choosing a managed switch, it's essential to carefully analyze specific needs and requirements to select the best solution for the network.
Here are some popular models from various manufacturers, including TP-Link, Cisco, Netgear, and D-Link:

Huawei offers managed switches with MPLS (Multiprotocol Label Switching) functionality, providing advanced routing and data forwarding capabilities in networks. MPLS facilitates fast and efficient data transmission by labeling packets, improving network performance, creating virtual private networks (VPNs), and supporting various protocols.
Models like S5720-HI, S6720-HI, and S7700 from Huawei are used in environments requiring advanced routing features, such as telecommunications networks, internet service providers (ISPs), data centers, or large enterprise-wide networks. With MPLS, these switches can efficiently manage network traffic, ensuring fast and reliable connections between different locations within the network.
MPLS enables the creation of label-switched paths, optimizing data traffic routing and providing Quality of Service (QoS) for various types of network traffic. Huawei switches with MPLS functionality are applied in networks demanding high throughput, low latency, and performance, as well as for services requiring quality guarantees, such as VoIP or video streaming.
Managed switches differ from regular or unmanaged switches primarily in their management and configuration capabilities. Unlike unmanaged switches, managed switches allow for VLAN configuration, Quality of Service (QoS), and security features like Access Control Lists (ACLs). This enhanced configurability provides more precise control over network traffic and increases network security.
Managed switches offer various features for advanced network management. Here are some of them:
VLAN (Virtual Local Area Network): Divides the physical network into logical subnets, enhancing security and data transmission efficiency.
Quality of Service (QoS): Enables prioritized data transfer, ensuring better performance for critical applications or services.
Bandwidth Monitoring and Management: Allows tracking and controlling network traffic to prevent overloads and ensure optimal performance.
Network Security: Provides advanced security features, including MAC address filtering, port access control, and protection against Denial of Service (DoS) attacks.
Port Control: Enables the activation or deactivation of specific ports, providing additional control over devices connected to the switch.
Diagnostic Monitoring: Diagnostic tools aid in troubleshooting network issues, ensuring a quick response to failures or abnormalities.
Remote Management: Configuration of remote management protocols like SNMP, Telnet, SSH, facilitating switch management from other devices.
These features allow flexible network configuration and adaptation to specific needs, providing a higher level of security and network performance.
Managed switches find applications in various environments and situations where advanced network management is necessary. Here are some examples of their use:
Enterprise Networks: Managed switches are used in corporate networks where configuring multiple VLANs, managing service quality, and ensuring security are essential.
Educational Environments: In schools, colleges, and educational institutions, managed switches enable effective network management by segmenting and controlling access to network resources.
Data Centers: In large data centers, managed switches are essential for efficient traffic management, high availability, and security implementations.
Hotel and Service Networks: In the hospitality and service industry, where multiple devices need to be serviced simultaneously, managed switches provide network traffic control and reliability.
Telecommunication Networks: In telecommunication infrastructure, managed switches are used to optimize bandwidth, traffic management, and ensure high-quality services.
Monitoring and Security Networks: In monitoring and security environments, where precise control of data traffic is crucial, managed switches facilitate traffic control and data analysis.
Internet Service Providers (ISPs): Managed switches are employed in ISP environments to manage links, diagnostics, and ensure network reliability.
Managed switches are versatile and flexible, making them suitable for various fields requiring advanced network control, increased performance, and security.
The configuration of managed switches can involve many aspects, and the process depends on the model and manufacturer of the switch. Here is a general overview
