What is a tiered switch

A tiered switch is a type of switch. According to the design, the switch can be stacked on top of the other. This switch is different from a rack switch and can be placed in a network cabinet or separately. The functionality of a tiered switch differs depending on the vendor and platform. Many tiered switches do not support advanced features such as quality of Service (QoS), multicast, and virtual LAN management. Puredata and DLink These two companies produce tiered switches that support some form of quality of service rule. Please refer to the manufacturer's technical support instructions for the features you need.

For access layer (access layer) switching technology, select a switch that supports virtual LANs, Secure Transport Protocol (STP), and IGMP (Internet Multicast Protocol). The quality of support services in this case is an added benefit that does not have to be deliberately pursued. I strongly recommend that you apply QoS at the rendezvous point in your switch. This is where the quality of service functions, scheduling, and queues are most needed.

Supplementary knowledge:

A switch stack is a dedicated connection cable from a manufacturer that connects directly to the down stack port of another switch from the "up" tiered port of one switch. To achieve the expansion of a single switch port number. A general switch can stack 4~9 units.

In order for the switch to meet the number of ports on a large network, the switch stack is generally used in larger networks. It is important to note that only stackable switches have this type of port, and the so-called stackable switch refers to a switch that typically has both "up" and "down" stacking ports. When multiple switches are connected together, they act like a modular switch, and the stack of switches can be managed as a unit device. In general, when multiple switch stacks exist, there is a manageable switch that can manage other "standalone switches" in this tiered switch with a manageable switch. Scalable switches make it easy to extend the network and are ideal for new networks.

All switches in the stack can be managed as a whole switch, that is, all switches in the stack are considered as a switch from the topology. A switch that stacks together can be managed as a single switch. The switch stacking technology uses a dedicated management module and a stack connection cable, the advantage of this is that with the addition of a user port, a wider broadband link can be established between the switches, so that each actual user bandwidth is likely to be wider (only if not all ports are in use). On the other hand, multiple switches can be used as a large switch to facilitate unified management.
