Introduction to industrial switch:

Industrial switches and commercial switches are positioned differently, so industrial switches pay more attention to stability, high temperature resistance, vibration resistance, corrosion resistance and other industrial characteristics. In the past few years, industrial switch manufacturers have mainly overcome several problems. How to make their products operate stably under different working conditions is their thinking. However, for the management of switches, everyone adopts the management mode of commercial switches. The management mode of the console is combined with the wizard mode of IE browsing and the network management software. The following describes the three management methods

1. Management through serial port: A serial port cable is attached to the network managed switch for switch management. First, plug one end of the serial cable into the serial port on the back of the switch, and the other end into the serial port of an ordinary computer. Then power on the switch and the computer. The HyperTerminal program is provided in Windows. Open the “super terminal”. After setting the connection parameters, you can interact with the switch through the serial cable. This method does not occupy the bandwidth of the switch, so it is called “Out of band management”.

In this management mode, the switch provides a menu driven console interface or command line interface. You can use the “Tab” key or the arrow key to move through the menus and submenus, press the Enter key to execute the corresponding command, or use the dedicated switch management command set to manage the switch. The command sets of switches of different brands are different, and even switches of the same brand have different commands. It is more convenient to use menu commands.

2. Management through network management software: All manageable switches follow SNMP protocol (simple network management protocol), which is a complete set of network equipment management specifications in line with international standards. All devices that follow the SNMP protocol can be managed through the network management software. You only need to install a set of SNMP network management software on a network management workstation, and you can easily manage switches, routers, servers, etc. on the network through the LAN. Through the interface of SNMP network management software, it is also an in band management mode.

3. Web management: The network management switch can be managed through the Web (network browser), but an IP address must be assigned to the switch. This IP address has no other purpose than to be used by the management switch. By default, the switch has no IP address. You must specify an IP address through the serial port or other methods to enable this management mode. When using a web browser to manage the switch, the switch is equivalent to a web server, except that web pages are not stored in the hard disk, but in the NVRAM of the switch. You can upgrade the web programs in the NVRAM through programs. When the administrator enters the IP address of the switch in the browser, the switch transmits the web page to the computer like a server, which makes you feel like visiting a website. This method takes up the bandwidth of the switch, so it is called “In band”. Web management can be carried out on the LAN, so remote management can be realized.
