How to determine whether to choose a managed or unmanaged switch

　　 Managed switch is to keep all network resources in good condition. Provides a variety of network management methods based on the terminal control port, based on the Web page, and supports Telnet to remotely log in to the network. Enables network managers to perform local or remote real-time monitoring of the working status of the switch and network operation status, and manage the working status and working mode of all switch ports.

What is an unmanaged switch?

　　Non-managed switches are relative to managed switches. The data of the network management switch will be configured through the Simple Network Management Protocol (SNMP). The SNMP protocol is currently the most widely used network management protocol based on TCP/IP networks. It can perform data address, port, protocol type, service, etc. Filtering, usually also has a VLAN division function. However, non-network management switches do not directly process data.

Unmanaged switch

Choose a managed or unmanaged switch: If the network is relatively simple, you can choose a plug-and-play unmanaged switch; if it is convenient for future maintenance, you may need to choose a managed switch. Only a managed switch can achieve ring topology connection .

　　 Network management and non-network management A key issue when choosing an industrial Ethernet switch is whether to choose a network management switch or a non-network management switch. Although managed switches are usually more expensive, they provide some additional powerful features. Managed switches include the characteristics of unmanaged switches.

　　Managed switches generally support Simple Network Management Protocol (SNMP). Of course, most managed switches do not only have this (SNMP) feature. Basically, managed switches allow you to control the network, while non-managed switches usually only allow Ethernet devices to communicate. The managed switch also enables you to monitor the network. Through SNMP, you can view various network statuses,

Including the number of bytes received/sent, the number of frames received/sent, the number of errors, and port status. All of these can be viewed port by port. "It is the ability of the switch to apply high priority to specific data frames.

Advantages of unmanaged industrial Ethernet switches:

　　 The price is cheap, reducing the network cost

　　The number of ports is dense, supporting more line access

　　 No need to set up, users can use it flexibly
