In the wide application of IIoT, industrial switches, as the core devices for network connection, have a direct impact on the stability, reliability, and scalability of the entire network system. When choosing an industrial switch, a key decision point is whether to choose a managed or unmanaged switch. This article will provide a detailed explanation of the differences, applicable scenarios, and selection strategies between the two from a professional perspective for those who need to use networking applications.

1. Definition and characteristics of network management type and non-network management type industrial switches

Network management industrial switch
Network management industrial switches have powerful network management functions, supporting multiple management methods such as SNMP simple network management protocol, Web management, and CLI command line interface. Users can remotely monitor the running status of the switch, configure network parameters, implement security policies, perform fault diagnosis and troubleshooting, etc. through these tools. In addition, the network management switch also provides advanced functions such as VLAN virtual local area network division, QoS quality of service control, port mirroring, link aggregation, etc., which help optimize network performance, improve network security, and meet complex network requirements.
Non-managed industrial switch
Non-managed industrial switches are relatively simple, and the network is configured and managed mainly through hardware switches or jumpers. They usually do not have remote management capabilities and do not support advanced network functions such as VLAN segmentation and QoS control. The advantages of unmanaged switches are low cost, plug-and-play, easy deployment and maintenance. However, as the size and complexity of the network expand, its limitations are becoming increasingly apparent.

2. Considerations for selecting network-managed and non-network-managed industrial switches

2.1 Network size and complexity

The size and complexity of the network are among the primary factors considered when selecting a switch type. For small, simple network environments, non-managed switches may be sufficient to meet the needs. However, with the expansion of network size and the increase of devices, the network topology structure becomes more complex, and the management and configuration requirements for switches also increase accordingly. At this point, the advantages of network management switches become apparent, as their powerful network management capabilities can help users better monitor and manage the network.

2.2 Network performance and security requirements

Network performance and security are another important consideration. Network management switches support advanced functions such as VLAN division and QoS control, which help optimize network performance, improve network bandwidth utilization, and ensure the transmission quality of critical business data. At the same time, by implementing security policies such as port security and MAC address filtering, network management switches can also effectively prevent security issues such as network attacks and data leakage. Non-managed switches are relatively weak in these aspects.

2.3 Maintenance and management costs

Maintenance and management costs are also one of the factors to consider when selecting the type of switch. Although the initial investment cost of non-managed switches is relatively low, as the network size expands and complexity increases, their maintenance and management costs may gradually rise. Because non-managed switches usually require manual on-site configuration and maintenance, this not only increases labor costs but also reduces work efficiency. Network management switches can be configured and maintained through remote management, reducing labor costs and improving work efficiency.

2.4 Future Extensibility

Future scalability is also a factor to consider when selecting the type of switch. With the continuous development of industrial Internet of Things technology and the increasing demand for application, the scalability of network systems has become increasingly important. Network management switches usually have better scalability, support more ports, higher transmission rates, and richer functions. However, non-managed switches may be limited by their hardware design and functional characteristics, making it difficult to adapt to future expansion needs.

3. Select strategy

3.1 Clarify requirements and scenarios

Before choosing a managed or unmanaged industrial switch, you first need to clarify your network requirements and application scenarios. including network size, complexity, performance requirements, security requirements, and future expansion needs. Only by clarifying these requirements can we more accurately choose the appropriate switch type.

3.2 Comprehensive evaluation of cost and performance

When selecting a switch type, it is also necessary to comprehensively evaluate the relationship between cost and performance. Although the cost of network management switches is relatively high, their powerful network management functions and advanced network features can significantly improve network performance and security. Although the cost of non-managed switches is lower, there may be deficiencies in network performance and security. Therefore, it is necessary to make trade-offs and choices based on actual needs.

3.3 Consider technical support and after-sales service

When selecting a switch, factors such as technical support and after-sales service also need to be considered. Choosing a manufacturer and brand with good technical support and after-sales service can ensure timely assistance and support when problems arise during use. This is of great significance for ensuring the stability and reliability of network systems.

Network management and non-network management industrial switches each have their own advantages and applicable scenarios. In the selection process, it is necessary to consider and weigh the actual needs. With the continuous development of industrial Internet of Things technology and the increasing demand for applications, the scale and complexity of future network systems will further increase. Therefore, the network management switch with strong network management function and advanced network features will become the first choice for more and more users. As senior R&D engineers in the industrial Internet of Things, we should pay close attention to technological development trends and market dynamics to provide customers with more professional, comprehensive and personalized solutions.
