Describes the vswitch connection methods and their advantages and disadvantages (1)

Vswitches should be the most common network devices in the network, and should be familiar to both enterprises and home users. Especially for enterprise network administrators, vswitches are very important devices in the network, regardless of the high-end or low-end. Therefore, we need to clarify the connection between switches.

I. Analysis of connection principles

If you have participated in the project implementation, you may know that the vswitch has two Connection Methods: cascade Uplink and Stack ). But how much do you know about the two connection methods? Next we will explain it one by one.

Cascade is the most common connection method, that is, using a network cable to connect two switches. The connection result is that in the actual network, they still work independently and are still two independent switches.

Stack is connected through the back panel of the switch, and is a chip-level connection. Generally, only medium and high-end switches provide the stack function. Dedicated stacking modules and stacked cables are also required. The result of the connection is that in the actual network, for other network devices and network personnel, they are a switch, that is, after the two 24-port switches are stacked, the effect is equivalent to a 48-port switch.
