Unmanaged 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 with VLAN division function is based on the TCP/IP network and uses a broad network management protocol. So what is the specific unmanaged industrial switch? This article introduces the characteristics and shortcomings of unmanaged industrial switches.
Features of unmanaged industrial switches
The unmanaged switch is a plug-and-play Ethernet switch, which does not directly process data. Because the non-network management switch does not require any settings, it can be used by plugging in the network cable, so it is also called a fool-type switch. Unmanaged industrial switches still have a considerable market in some specific industries and fields, such as the power industry, coal industry, and transportation industry.
Unmanaged switches are also called fool-type switches. Simply put, they do not directly process data. The non-network management switch can be plugged into the network cable. It is a data link layer device. It can identify the MAC address information in the data packet, and then forward it according to the MAC address and record these MAC addresses and corresponding ports in an internal address table. .
Disadvantages of unmanaged industrial switches
1. Unmanaged industrial switches have limited functions and are suitable for home or small networks.
2. Unmanaged industrial switches do not support ARP protection.
The arp attack is not a virus and almost all anti-virus software can do nothing about it; but it is better than a virus-because it can slow down the communication and paralyze the network, and in severe cases it can also cause information leakage.
3. Non-managed industrial switches do not support the binding of mac addresses.
4. Unmanaged industrial switches do not support VLAN division.
End users connected to non-network-managed industrial switches are in the same broadcast domain, a broadcast storm will erupt, and they cannot be protected and controlled. Congestion, blocking, and flooding of the entire network may cause the entire network to be paralyzed.
5. Unmanaged industrial switches do not support flow-based control.
6. Unmanaged industrial switches have poor data transmission reliability and serious packet loss.
7. The unmanaged industrial switch has a single assembly, which has major limitations for network upgrade and expansion.
8. Unmanaged industrial switches are inconvenient to manage, which leads to a relatively high hardware failure rate.
Regarding the issue of unmanaged industrial switches, this article introduces its characteristics and objective shortcomings. In short, there are many differences between the unmanaged industrial switches and the managed industrial switches. In terms of performance, they are not as good as the managed industrial switches. However, unmanaged industrial switches also have their own advantages, such as ease of use.
