You have no control over this process. But the time will come to achieve more than basic communications. And a managed switch will allow you to create a fully optimized network by being able to configure the network for performance and to monitor the network for status. With a managed switch, you can choose the optimal operating parameters for your network ports instead of using auto-negotiated settings.
Within the managed switch are data locations that supply a wealth of knowledge about how the system is operating. For example, by using SNMP, you can examine how many messages and message types are being received and sent from each port. You can also identify the number of dropped or faulty packets in order to check the system for devices that may be causing communication problems. Since you can examine traffic flow, you may decide to take action to control the traffic flow. This example illustrates such a point.
You may have a work cell that contains PLCs connected to operator interfaces, vision systems, motion control and also a data collection computer. Remember that the PLCs, OIs, vision and motion systems require the maximum bandwidth for communicating to each other in order to maintain their real-time performance. The data collection computer can get information at a slower rate and still supply the information in a timely manner to a management information system.
To accommodate these differing communication requirements, Quality of Service QoS is used to prioritize messages. In industrial environments, unmanaged switches are often deployed across small networks, to connect edge devices or add temporary groups of devices to a larger network. Surveillance cameras are a real-world illustration of where an unmanaged switch might be used. The unmanaged switch then sends the data to a managed switch and up through the network. When comparing costs between managed vs.
Managed switches provide the same functionality as unmanaged switches—connecting Ethernet devices for communication purposes—but they offer additional features that unmanaged switches cannot. A managed switch makes it possible to manage, configure, monitor and troubleshoot issues with your network. Each switch has its own IP address for identification and addressing. You can create traffic controls, prioritize channels based on the importance of data, investigate performance problems, remotely deploy fixes and even create new virtual networks for segmentation purposes.
You get to choose the ideal operating parameters for your network ports. Because they can monitor and control network events, they can quickly shut down detected threats, prevent unauthorized access and encrypt communication. They also feature built-in redundancy so data is duplicated and can be recovered if a device or network fails.
In terms of applications, managed switches are most often deployed as part of the industrial network backbone to monitor and control traffic. This price usually depends on how many ports you need the switch to have. With managed switches, however, you should expect significantly higher costs. Size is not the only thing that matters when deciding on the right switch, as you can get switches with any number of ports, both managed and unmanaged. However, when it comes to smaller networks, such as for small businesses, the home, a single office, or so on, then an unmanaged switch is more likely to be used.
Managed switches are better suited to enterprise-sized businesses with a much larger network scope, or for those that use things data centers and need much better control over the traffic within their network. This question cannot be so simply answered. A network manager or technician is usually the one best qualified to help you choose a network switch based on your needs. If there are thousands of users on the network at any one time, however, then managed switches are crucial.
For instance, security may play a large role in your choice. Even if your network is relatively small, if there is a lot of highly sensitive data customer data, financial details, etc. Similarly, if your business frequently works with clients and partners that need a temporary, limited degree of access to your network, then the VLAN function of the managed switch might be necessary to ensure security.
Managed switches Managed switches give you greater security and more features and flexibility because you can configure them to custom-fit your network.
