Before, we briefly introduced the three management methods of the network management switch. First, manage through the serial port; second, manage through the web; third, manage through the network management software. Today, the editor of Feichang Technology will introduce in detail how to control and manage the network management switch through the serial terminal configuration. What is the correct operation procedure? Let's take a look!
The biggest advantage of managing the network management switch through the serial port is that it solves the problem of the default IP address of many switches. The switch is the transportation hub of the campus network system, and its management characteristics determine the overall performance of the campus network. Some managed switches do not have a default IP address, so they cannot be managed through Telnet or Web during initial configuration. At this time, we need to manage the switch through the serial port.
Steps to manage the switch through the serial port
1. Connect the switch and the PC.
First, you need to connect the PC and the managed switch together before you can manage it. Manageable switches are equipped with a serial cable for local management by network administrators. First plug one end of the serial cable into the Console port on the back of the switch, and tighten the screws at the same time to prevent poor contact. The other end of the serial port cable is plugged into the serial port of the ordinary PC. At this time, remember that the cable is plugged into the COM1 or COM2 port. You will need it for future settings.
2. Set up "Hyper Terminal"
After the connection is made, power on the managed switch and the computer and turn it on. Windows 98/Me/2000 all provide the "Hyper Terminal" service, if not, you can add it in the "Communication" group in "Add/Remove Programs". You can also use other terminal emulation programs that comply with the VTY100 (a standard for terminals, which is rare now).
When you run "Hyper Terminal" for the first time, the system defaults to connect via Modem, and you will be asked to enter the area code of the connection, just enter one. If there is no modem installed in your computer, it will prompt "The modem must be installed before connecting. Do you want to install it now?", click the [No] button here.
After the program runs, you will be prompted to establish a new connection name, we enter "Switch" here. After clicking the [OK] button, a window will appear, asking the user to select which port to use when connecting. It must be noted here that the serial number of the PC serial port you are connected to should be selected. If you are not sure, you can use "Serial Port 1" and "Serial Port 2" to try separately.
After the serial port number, click the [OK] button, and a COM port properties window will appear, which contains parameter settings such as baud rate, data bits, parity, stop bits, and flow control. How to set so many parameters? In fact, it does not matter, as long as you click the [Restore Defaults] button, the most conservative parameter settings will be recalled. The default parameters are applicable in most connection conditions, so users don't have to spend time studying these parameters. After setting the connection parameters, the program will automatically execute the command to connect to the managed switch. what! Why is the interface blank? Don't worry, press the Enter key, and the true face of the main interface of the managed Ethernet switch management interface has finally appeared.
From now on, you have to forget the existence of the mouse, and all controls must be implemented through the keyboard. But the operation is very simple: use the Enter key to execute commands, use the "Tab" key or arrow keys to move through the options, and use the space bar or the keyboard letter keys or number keys to change a parameter. Before logging in to the operating system, the user needs to enter the administrator user name and password.
The default user names of most device administrators are named after meaningful English words such as "Admin" and "Super". Some switches have initial passwords, while others do not. You can understand this information by carefully reviewing the switch manual.
Well, the above content is the detailed explanation of the operation steps of Feichang Technology to control the network management switch through the serial port.
