In this article, ETU-LINK will take you to talk about network management switches and non network management switches. With the development of the network, the demand for switches is also increasing. Many switch parameters will be written with network management switches or non network management switches. What is the difference between the two?

The non network management switch is also known as the fool type switch, that is, it does not directly process the data, and can be used by plugging in the Internet cable. It belongs to the data link layer device, which 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 the corresponding ports in its own internal address table.

The non network management industrial switch has limited functions and single assembly, which is suitable for small networks and can not be applied in large and medium-sized networks. It has great limitations in network upgrading and expansion, and does not support ARP protection. However, its advantages are low price and easy to use.

Compared with the non network management switch, the price of network management switch is slightly more expensive, and the operation is more complex, so it needs to be configured. But it has many advantages, such as: the backplane bandwidth is large, the data forwarding speed is faster; Flexible networking, application of large and medium-sized network access layer; It supports VLAN partition. Users can partition different areas according to different applications to control and manage the network effectively; It has ARP protection function to reduce ARP spoofing; Easy to expand, flexible application, can be managed by network management software, can also be remote access through its own access control, increase network security and controllability and so on.

Network management switch can provide different types of ports, such as SFP port, SFP28 port, QSFP port, QSFP28 port, etc. These interfaces are used for data transmission, and can access optical communication products such as optical module / DAC direct attach cable / AOC active optical cable.

Taking the connection of SFP+ ports as an example, if it is a short-distance device interconnection, a lower cost 10G DAC high-speed cable solution can be used, or a 10G AOC active optical cable solution can be used. If the transmission distance is long, it is necessary to use optical modules with jumpers for transmission. Common optical modules include Gigabit multi-mode 550m, Gigabit single-mode 10km, 10 Gigabit multi-mode 300m, 10 Gigabit single-mode 10km, etc. ETU-LINK's optical module product specifications can be made according to customer needs custom made.

So, do we choose NMS or NMS switches? If the network is relatively simple, plug and play non network management switch can be selected; For the convenience of future maintenance, it may be necessary to choose the network management type, because only the network management type switch can achieve the ring topology connection. The above is the switch selection method introduced by ETU-LINK. Thank you for your support.
