Compared with ordinary switches, core switches need to have the following characteristics: large cache, high capacity, virtualization, FCOE, layer 2 TRILL technology, etc. So, what are the advantages of core switches over ordinary switches?

Ethernet switch manufacturers have launched Layer 2, Layer 3 or even Layer 4 switches basing on market demand. But no matter which kind of switches, its core function is still two-layer Ethernet data packet switching, including certain ability to process IP layer or even higher layer data packets. Now, we’d like to introduce the differences and characteristics of layer 2 switch, layer 3 switch and layer 4 switch in detail.

Upgrading Cisco C3850 Switches to Solves the Problem of High CPU Occupancy. According to our customer’s feedback, the CPU usage rate of a Cisco aggregation switch has increased recently.

The Cisco Catalyst 9200 is the first switches to replace the Cisco Catalyst 2960X in fixed enterprise switching access platforms. It is designed for security, resiliency and programmability. Today we will discuss the difference between Cisco Catalyst 9200 and Cisco Catalyst 2960X.

Components of a Cisco router,Cisco routers are composed of hardware and software. The hardware mainly includes the central processor, memory, interfaces, console ports and auxiliary ports, etc. The software is mainly the router's IOS operating system

The switch can transmit data between multiple pairs of ports at the same time. Each port can be regarded as an independent physical network segment, namely non-IP network segment, which is connected to its network device and enjoys all the bandwidth independently without competing with other devices for use. So, do you know the port structure and port types of the switch?

Cisco Catalyst 3750-X series, as stackable switches, are enterprise-grade products. These switches provide continuous connectivity, scalability, security, energy efficiency and ease of operation through innovative features such as Cisco StackPower, IEEE 802.3at Enhanced Power over Ethernet (PoE+) configuration, optional network modules, redundant power supplies, and Media Access Control Security(MACsec), etc.

The Cisco Catalyst 9200 Series enterprise-class access switches extend the broader deployment of innovational functions of Catalyst 9000 hardware and software basing on intent networking. In contrast to the scale and multifunction of the Catalyst 9300 Series switches, the Catalyst 9200 Series switches focus on providing proper switches for simple branch office deployments. With its family pedigree, the Catalyst 9200 Series offers uncompromising simplicity and security. The switches also support

What is a fiber optic switch? And what are the types of fiber optic switches? A fiber optic switch is a high-speed network transmission relay device. Compared with ordinary switches, they use fiber optic cables as the transmission medium. The advantages of optical fiber transmission are fast speed and strong anti-interference ability.

The development of PoE power supply technology is gaining momentum. With its advantages of simplified installation of electrical equipment, deployment, energy saving and safety, PoE technology has been widely used.Today we will sort out the frequently asked questions and answers about PoE switches.

The most common equipment in network equipment maintenance is network switches, especially the access layer switch. Connecting users and switching routing devices, as an intermediate, network switches play a vital role in troubleshooting network failures. Here are some common faults and solutions for switches.

Stackwise Technology, an innovative stacking architecture, is used on Cisco 3750 Series switches to provide 32Gbps stacking interconnect. It can connect up to 9 switches and turn them into a unified, logical and convergence-optimized device so that users can deploy voice, video and data application comfortably. Cisco 3750 series switches adopt the way of backplane bandwidth stack, and the models themselves have stacking ports and can reach 32G backplane bandwidth by using specific stacking lines
