Precautions and categories for purchasing cisco Gigabit Switches

Precautions and categories for purchasing cisco Gigabit Switches. We will introduce the precautions for cisco Gigabit Switches. Many people may not know how to classify cisco Gigabit Switches, after reading this article, you must have gained a lot. I hope this article will teach you more things.

At present, Gigabit Ethernet has become a strategic choice for high-speed and enterprise-level broadband network applications thanks to its fast and stable advantages. Recently, my company has taken into account the increase and development trend of its employees and the need to transform and upgrade the original MB network to ensure network bandwidth.

Make sure that all cisco Gigabit Switches are used as the switch devices for the enterprise network to achieve Mbit/s to the desktop. As the head of the network department, I took charge of the purchase of cisco Gigabit Switch products. After a period of investigation and analysis, the author successfully completed the task and summarized some purchase precautions and common purchase mistakes. By protocol layer, cisco Gigabit Switches can be divided into L2 cisco Gigabit Switches, L3 switches, and L4 switches. The higher the layer, the higher the technical performance of the cisco Gigabit Switch.

Classification of cisco Gigabit Switches

Cisco Gigabit Switches are generally used in the backbone network of large enterprise Ethernet. They can use optical fiber and twisted pair wires, which correspond to SC and RJ-45 ports respectively. It has multiple categories. From the perspective of LAN design and application, cisco Gigabit Switches can be divided into three categories: cisco Gigabit Switches, Gigabit working group-level cisco Gigabit Switches, And gigabit desktop cisco Gigabit Switches.

By working protocol layer, cisco Gigabit Switches can be divided into Layer 2 cisco Gigabit Switches, Layer 3 switches, and Layer 4 switches. The higher the supported protocol layer, the higher the technical performance of the cisco Gigabit Switch.

Pay attention to the eight-point purchase of cisco Gigabit Switches

Like a common m switch, when purchasing a cisco Gigabit Switch, you must determine the performance of the cisco Gigabit Switch. The main reason is to pay attention to the performance indicators of the cisco Gigabit Switch, for example, switching mode, port type, backboard bandwidth, and network management functions. In addition, because cisco Gigabit Switches are relatively expensive, it is essential to consider the price and service.

Price, brand

Currently, the prices of cisco Gigabit Switches sold in the market is extremely chaotic, such as the domestic Huaji technology visida VCT) 5280GPcisco Gigabit Switch 1) prices only 1800 yuan, TP-LINK TL-SL3226P prices in 2750 ~ Between 3500 RMB. The foreign manufacturers of similar products is 5000 or 6000 yuan, tens of thousands or even hundreds of thousands of yuan, such as Cisco WS-C4006-S4-DC price is 100,000 yuan.

Therefore, when purchasing a cisco Gigabit Switch, you must pay attention to the price and be sure to compare the prices with the three. In addition, in terms of the cisco Gigabit Switch brand, the product quality of foreign manufacturers such as Cisco and 3Com is guaranteed. Although many domestic manufacturers have also begun the production of cisco Gigabit Switches, we recommend that you choose products from well-known manufacturers, such as TP-LINK, D-Link, Lenovo, and Huawei-visida.
