Simple Steps for configuring a vswitch

Through the LAN, you can easily manage vswitches, routers, and servers on the network. Through SNMP network management software, it is also an in-band management method, so which method you use depends on your security and manageability requirements.

Many people may not have a special understanding of the configuration of the network-managed switch. Here we mainly introduce the specific configuration steps of the network-managed switch. The configuration of the network-managed switch has always been very mysterious, not only for general users, there are two main reasons for this: first, most of the vswitches configured by enterprises are non-Network-connected vswitches on the desktop, which do not require any configuration at all. They are purely "Dummies" and are connected to power supplies like hubs, 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 engineers or other professionals to configure the network manager. Therefore, it is difficult for these network administrators of small and medium-sized enterprises to configure a network manager switch by themselves.

The detailed configuration process of vswitches is complex, and the specific configuration methods vary depending on different brands and series of vswitches. This article only teaches you the general configuration method, with these general configuration methods, we will be able to link them together.

You can configure a vswitch in two ways: local configuration and remote network configuration, however, note that the latter configuration method is only available after the previous configuration is successful.

Local Configuration

For local configuration, we need to first encounter the physical connection mode, and then we need to face the software configuration, in terms of software configuration, let's take the most common Cisco "Catalyst 1900" network-managed switch as an example. The local configuration of the network-managed switch involves hardware and software connections. The following two steps describe the basic connection process of the configuration.

Physical connection

Because of the portable performance of the laptop, the switch is usually configured with a laptop. In the absence of a laptop, you can also use a desktop, but it is more difficult to move. The local configuration of a vswitch is to communicate directly through the "Console" Port of the computer and the vswitch, as shown in figure 1.

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 to configure and manage the vswitch.

Although there are several other ways to configure and manage vswitches, such as Web and Telnet), these methods must be configured through the Console port. Because IP addresses are often used in other methods.

The domain name or device name can be implemented, and the newly purchased switch obviously cannot have these parameters built in, therefore, connecting to and configuring a vswitch through the Console port is the most common and basic management and configuration 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 DB-25 serial interface or a RJ-45 interface, you need to connect to a serial port configured with a computer, usually called a terminal, through a dedicated Console line. 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 ).

The two ends can be inserted into the computer's serial port and the Console port of the switch; the other is the two ends are RJ-45 joint RJ-45-to-RJ-45) flat line. Because both ends of flat line are RJ-45 interface, can not be directly connected with the computer serial port.

Therefore, you must also use an adapter for a RJ-45-to-DB-9 or RJ-45-to-DB-25 as shown in 3. In general, such a Console line and the corresponding DB-9 or DB-25 adapter will be randomly presented in the box of the netmanager switch.
