Learn to configure switch stack to enter the peak of New Technology

Users who have learned how to configure switch stacks step into the peak of new technologies and configure switch stacks and cascade connections have heard of these two concepts. The following is a brief introduction. The so-called stack is to use a dedicated line to connect the backplane of the switch together. This method is more stable and has good transmission performance, because the backplane speed is much higher than that of common ports.

As a network administrator, we all face the work of configuring switch stacks. After all, almost all small and medium enterprises have established their own networks, and the most common device connecting to each computer is the switch. Therefore, maintenance of vswitches falls into the network administrator.

Some readers may say that the switch cannot be connected? Do I still use configuration? In fact, if you only use the interconnectivity function of the vswitch, connect the vswitch to the power source and connect the computer and the vswitch port with the anti-line connection.

However, as a qualified network administrator, you must use not only network devices, but also network devices. Therefore, you should have a clear and in-depth understanding of switch configurations. In fact, in daily work, the network administrator often receives tasks such as optimizing the network assigned by the leadership, in this case, it is very important to know whether the switch configuration operation can be performed.

There are many types of vswitch configurations. Today we will talk about the configurations for connecting vswitches. Because there are only 48 vswitch ports on the market, and the number of internal computers in the company is far more than 48, If you want all the company's computers to connect to one CIDR block, at least two or more switches are required. How to connect these vswitches together becomes a challenge.

Configure switch stack and cascade:

Two methods are provided to connect multiple switches, namely configuring switch stacks and cascade connections. Readers who have some basic knowledge must have heard of these two concepts. Below is a brief introduction. Cascade connection is the most common and simplest way to connect a vswitch. It uses a network cable to connect two ports of the two vswitches. This network cable must be retained.

Of course, we can also use a network cable to connect the UPLINK interface of a vswitch and the normal port of another vswitch. What we need is the main line. Using this method to connect multiple vswitches is called a cascade connection. It is very simple in operation, but it affects the performance to a certain extent, after all, the transmission between switches is limited to a small speed of M ports, and the transmission stability is also worth considering.

The method for connecting multiple switches corresponding to cascade is the focus of this article-stacking. The so-called stack is to use a dedicated stack line to connect the backboard of the switch together. This connection method is more stable, and the transmission performance is also guaranteed, because the backboard speed is much higher than the normal port.

Companies that do not have the conditions to configure the switch stack can use the cascade method to connect multiple switches without any configuration. Stack is different. We need to configure the corresponding parameters for switch stack.
