Getting Started: vswitch Configuration

Beginner's portal: vswitch configuration skills. Many things are involved in vswitch configuration skills. There are also many technical methods for vswitch configuration techniques, so there will be a bit of confusion in the selection of methods. The following shows you a way.

The vswitch configuration technique has always been mysterious, not only for general users, but also for most network administrators. It is also an important and basic indicator for measuring the level of network management. This is mainly due to two reasons: first, the vswitches used by most enterprises to configure their vswitches are non-Network-connected vswitches on the desktop. They do not need any vswitch configuration skills at all. They are pure "Dummies", just like hubs, connect to the power supply and plug in the network cable to work properly.

On the other hand, most CEOs of medium and small enterprises are not very reassured by their network administrators, so even if the purchased switch is of the network management type, their network administrators are not allowed to configure it, instead, ask the manufacturer's engineers or other professional personnel for configuration. Therefore, it is difficult for these network administrators of small and medium-sized enterprises to have the opportunity to manually configure a switch.

The process of vswitch configuration skills is complex, and the specific vswitch configuration skills vary with different brands and series of vswitches. This article only teaches you how to configure general-purpose vswitches, with these general-purpose Switch configuration techniques, we will be able to draw a line between them.

Generally, a vswitch can be configured in two ways: Local Switch configuration and remote network switch configuration, however, note that the latter configuration method is only available after the previous configuration is successful.

How to configure a Local Switch

The first thing we need to know about the configuration of a local switch is its physical connection method, in terms of software switch configuration techniques, let's take the most common Cisco "Catalyst 1900" switch as an example. Because the configuration of the local switch of the switch involves hardware and software connections, the following two steps describe the basic connection process of the switch configuration technique.

Physical connection

Because of the portable performance of the laptop, switch configuration skills are usually carried out using a laptop. In the absence of a laptop, you can also use a desktop, but it is more troublesome to move. The local configuration method of the vswitch is to communicate directly through the "Console" Port of the computer and the vswitch.

There is usually a "Console" port on the vswitch that can manage the network. This is already described in the previous section of the hub, and the same is true for the vswitch ), it is used to configure and manage vswitches. Connecting to and configuring a vswitch through the Console port is required for vswitch configuration and management.

There are several other ways to configure and manage vswitches, such as Web and Telnet, these methods must follow * Basic Switch configuration skills through the Console port before proceeding. Because the IP address, domain name, or device name is required for other methods, the newly purchased switch obviously cannot have these parameters, therefore, connecting to and configuring a vswitch through the Console port is the most common and basic method that must be mastered by the network administrator.

Different types of switch Console ports are located in different locations, some on the front panel such as Catalyst 3200 and Catalyst 4006), and some on the rear panel such as Catalyst 1900 and Catalyst 2900XL ). Generally, most modular switches are located on the front panel, while most fixed configuration switches are located on the rear panel. However, you don't have to worry about the failure to find the Console port. There will be a "CONSOLE" icon on the top or side of the port.

In addition to location differences, the Console port type is also different, the vast majority of the Catalyst 1900 and Catalyst 4006) are using RJ-45 Port 2 ), but there are also a few using DB-9 serial port such as Catalyst 3200) or DB-25 serial port such as Catalyst 2900 ).

Whether the switch uses a DB-9 or a DB-25 serial interface, or a RJ-45 interface, you need to connect to the switch through a dedicated Console line configuration techniques commonly referred to as a terminal) of the serial port. The Console line corresponds to the different Console ports of the vswitch. There are also two types of Console lines: one is a serial line, that is, both ends are serial interfaces and both ends are master ports ), both ends can be inserted into the serial port of the computer and the Console port of the switch respectively.

The other is flat wire at both ends of the RJ-45 joint RJ-45-to-RJ-45. Since both ends of the flat line are RJ-45 interfaces, you cannot connect directly to the computer's serial port, so you must also use an adapter for a RJ-45-to-DB-9 or RJ-45-to-DB-25 shown in 3 at the same time. Typically, such a Console line and the corresponding DB-9 or DB-25 adapter are randomly presented in the switch box.
