The switch is the transportation hub of Internet cafes, campus networks and enterprise LANs. Its management characteristics determine the overall performance of the LAN connected through the switch. Some network management switches do not have a default IP address, so they cannot be managed through Telnet or Web during initial configuration. At this point, we need to manage the switch through the serial port.
The configuration and management of the network management switch through the RS-232 serial port (or parallel port) is a common type of local configuration of the switch. Through serial communication, data is only transferred between the switch and the management machine. Therefore, the advantage of the serial communication of the switch is that the security is very strong; however, due to the limitation of the length of the serial cable, remote management cannot be realized. As a way of switch configuration management, you can also find out if you are interested.
The network management switch usually comes with a serial cable for the network administrator to configure and use the switch locally. The first thing we need to do is its physical connection, and then we need to face the software configuration.
Physical connectionThe first thing we need to do is its physical connection. Because the switch is one of the network devices in the internet, the installation location is usually a certain distance from the computer, and the laptop has portable performance, so the switch is usually a notebook. The computer is going on. In the case of no notebook, of course, you can also use a desktop, but it is more troublesome to move. The local configuration of the switch is through the way that the computer directly connects to the "Console" port of the switch. Connect one end of the console cable to the console port of the switch and tighten the screws to prevent it from falling off or being in poor contact. Connect the other end to the serial interface of your computer. Remember to plug the cable into the COM1 or COM2 port.
Software configurationAfter the physical connection is complete, we can turn on the power of the computer and the switch for software configuration. Before entering the configuration, we need to enter the system first. The steps are as follows:
Step 1: Open the computer connected to the switch and run the Windows operating system.
Step 2: Check if the "Hyper Terminal" component is installed. If the component is not found in the "Accessories", the Windows component can be added via the "Add/Remove Program". You can also use other terminal emulation programs that conform to the standard VTY100 (a standard for terminals, which is now rare).
Well, after the "hyper terminal" is installed, we can communicate with the switch (make sure it is connected and open the switch)
The thing we have to do right after buying a switch is to do the configuration work.
The first time you buy a switch, you can only configure it through com;
In general, we can directly configure the switch with the HyperTerminal that comes with Windows.
