Telnet connection Configuration

The advantage of Telnet is obvious to all. You can easily perform remote control. Its installation and related operations are very simple and favored by users. However, its security problems have always been a headache. Here we will discuss the issues related to the Telnet connection.

Telnet is a remote access protocol that can be used to log on to a remote computer, network device, or a dedicated TCPIP network. windows 9598 and later Windows systems, UNIX, Linux and other systems have built-in Telnet client programs, we can use it to achieve communication with remote switches.

Before using Telnet to connect to a vswitch, make sure that you have prepared the following:

◆ Install the TCPIP protocol on the computer used for management, and configure the IP address information.

◆ IP address information has been configured on the managed switch. If IP address information has not been configured, you must set it through the Console port.

◆ A user account with administrative permissions is created on the managed switch. If a new account is not created, the default Administrator Account of the Cisco switch is "Admin ".

Run the Telnet client program on the computer. This program is available in Windows and UNIX and Linux systems, and its usage is basically compatible, especially in Windows ), and log on to the remote switch. if the IP address of the vswitch has been set to 61.159.62.182, the following describes how to enter the configuration interface. As for how to configure the vswitch, it depends on the actual situation, do not give a detailed description. the steps for entering the configuration page are simple, just two simple steps:

Step 2: click the "Start" button and select the "run" menu item. Then, in the dialog box, press "Telnet 61.159.62.182" to enter the logon address. You can also leave the IP address unspecified, after entering the Telnet main interface, connect again, but this will take another step. It is better to directly enter the IP address to be connected), as shown in. if you have configured a name for the vswitch, you can enter the name of the vswitch directly with a blank space after the "Telnet" command.

The Telnet command is generally formatted as follows:

Telnet [Hostnameport]. Note that "Hostnqme includes the vswitch name, but we have configured an IP address for the vswitch in front of it, therefore, here more refers to the IP address of the switch. the "Port" following the format is generally not required. It is used to set the Port used for Telnet connection. Generally, the Telnet communication Port is specified as Port 23 in the TCPIP protocol, it is better not to change it, that is, we can ignore this parameter.

Step 2. After entering the information, click "OK" or click the Enter key to establish a connection with the remote switch. as shown in the following figure, the interface is displayed when you establish a connection with a computer through the Tetnet and ipvst1900 switch.

The figure shows the configuration Menus including Menus and CommandLine. Then, you can configure and manage the vswitch as needed.
