Introduction to switch stack knowledge and switch stack principle

This article introduces the knowledge of switch stack and the principle of switch stack. There are many problems with switch stack on the network. For vswitches of various models, a q & A topic about switch stack is provided below. I hope to give all questions about switch stack for netizens.

A switch stack is a type of switch. According to the design, this type of switch can be stacked on the other. Different from Rack-mounted switches, such switches can be placed in network cabinets or separately. The switch stack function varies with the vendor and platform.

Many switch stacks do not support Quality of Service (QoS), multicast, and virtual LAN Management. The switch stacks produced by PureData and DLink support some form of service quality rules. For the features you need, refer to the vendor's technical support instructions.

For access layer (access layer) switching technology, you need to select a switch that supports Virtual LAN, secure transmission protocol STP), and IGMP Internet multicast protocol. In this case, the quality of support services is an additional benefit and does not have to be pursued. I strongly recommend that you apply QoS at the junction of your vswitch. This is the most important part of Service Quality functions, scheduling, and queue.

Additional knowledge on switch Stack:

A switch stack is a dedicated connection cable provided by the manufacturer. The "UP" Switch stack port of a switch is directly connected to the "DOWN" Switch stack port of another switch. To expand the number of ports of a single vswitch. Switch stack 4 ~ 9.

 

Switch Stack

To meet the port quantity requirements of large networks, switches are usually stacked in larger networks. Note that only the vswitch stack can have this port. The so-called vswitch stack means that a vswitch usually has both the "UP" and "DOWN" Switch stack ports.

When multiple switches are connected together, they act like a modular switch. A switch is stacked together and managed as a unit device. In general, when multiple switches are stacked, one of them can be managed switch, which can be used to manage other "independent switches" in the stack. The switch stack can easily expand the network, making it the best choice for creating a new network.

All switches in the switch stack can be managed as a whole switch. That is to say, all switches in the switch stack can be considered as a switch in the topology. A stack vswitch can be managed as a switch in a unified manner. The switch stack technology uses a dedicated management module and stack connection cable.

The advantage of this is that, on the one hand, the user port is added, and a wide broadband link can be established between switches, in this way, the bandwidth used by each user may be wider only when not all ports are in use ). On the other hand, multiple switches can be used as a large switch to facilitate unified management.
