Layer-3 switches are quite common, So I studied the mainstream enterprise-level layer-3 switches in the market and shared them with you here. I hope they will be useful to you. In recent years, the popularity of networks and the development of enterprises have overwhelmed the traditional exchange system, and the network environment of enterprises has been restricted. How to do a good job in enterprise netwo

With the development of enterprise network applications, people are no longer satisfied with the desktop network speed of 100 MB. Many people are looking for faster LAN connection technologies, using Gigabit Ethernet or faster 10-Gigabit technology. Such a change not only occurs in the backbone of the campus network, but also in each wiring room. The IT management personnel of the enterprise hope to provide 10 times the previous network connection for each desktop user. There are many reasons to

addition, the performance, latency, and jitter of the port itself are all factors in the performance of the switch. David Newman, president of Network Test and member of the Network World Test alliance, said: "Everyone mentioned the line rate per port. Now the problem is how many ports can you reach the wire speed before packet loss occurs ." Based on published Device specifications, the largest enterprise-level Core switches include Force10 E1200, F

affected.The above three points are also the main technical parameters used to judge the performance of Layer 2 and Layer 3 switches. Please pay attention to the comparison when considering device selection.2) routing technologyThe router operates on the layer 3 of the OSI model-the network layer. Its working mode is similar to that of the Layer 2 switch, but the router works on the layer 3, this difference determines that routes and

How switches work I. Overview In 1993, LAN switching equipment emerged. In 1994, the exchange network technology boom began in China. In fact, the exchange technology is a simplified, low-cost, high-performance, and high-port intensive exchange product, reflecting the second-layer operations of the complex exchange technology in the OSI reference model. Like the bridge adapter, the switch simply decides to forward information based on the MAC addr

Layer-2 switches are data link layer devices that can identify MAC address information in data packets and forward data based on MAC addresses, the MAC addresses and corresponding ports are recorded in an internal address table. The specific workflow is as follows:(1) When the switch receives a packet from a port, it first reads the source MAC address from the packet header, so that it knows the port on which the machine with the source MAC address is

The port of the core switch is mainly a fiber type, but the price of the switch fibre port is very expensive and requires special attention from the user, while the fibre port of the switch is not stacked and can only be used for cascading purposes. Analysis of the switch fiber port Cascade connection mode and basic types, welcome to add message. Cascading can use either a normal port or a special mdi-ii port. A pass-through cable should be used when the two ports that are cascaded are normal (

An article entitled "Better sustainable deployment with functional switches" was published in the previous Infoq column, which explains the integrated application of feature switches and spring. But if the project doesn't depend on spring, how do you better use the feature switches? At the same time, how to transparently introduce, so that the project does not re

With the improvement of computer performance and the increasing traffic, traditional local area networks are getting more and more out of their load. The exchange Ethernet technology has emerged, greatly improving the performance of local area networks. A network switch can significantly increase the bandwidth and establish a geographically dispersed network. Each port of a LAN switch can transmit information in parallel, securely, and in real time. It features stable performance, flexible struc

Brief Introduction to the configuration process of OSPF-based Huawei switch routing protocol. The configuration of Environment Parameters in Huawei switch routing will be covered in the following text, including the relevant configuration process, will be displayed to you. Invest in the world of Huawei switch routing. Router features and networking of Huawei Switches "Environment parameters for Route configuration of Huawei

In-depth analysis of vlan settings and faults of Huawei switches. When using Huawei switches, users often encounter vlan settings of Huawei switches, in the following article, I will reply to you using routers to forward data between two vlan settings of different Huawei switches. Networking requirements The two PCs ar

Group telephone switches are mainly used in small and medium-sized enterprises. How can enterprises correctly purchase group telephone switches? How to save business expenses? Every day, small and medium-sized enterprises are eager for sound and rapid growth. from the perspectives of market, operation management, enterprise competitiveness, and enterprise operation, small and medium-sized enterprises undoub

With the help of today's advanced smart enterprise networks, enterprises can effectively deploy e-commerce and other applications, thus realizing the optimized combination of labor and the globalization of business. These powerful networks can connect many remote sites, branch offices, mobile employees, partners and customers to provide services for thousands of users. However, there is still a problem that all networks are increasingly threatened by the increasing number of security risks on En

An improper port connection between Ethernet switches in Ethernet may cause a network loop. If the related switch does not enable the STP function, such a loop will lead to endless data packet forwarding, forming a broadcast storm, this causes network faults. One day, we found a problem with a VLAN in the campus network performance monitoring platform-the connection between the access switch and the campus network was interrupted. Check the aggregatio

The following describes how to use a Cisco switch and how to operate it. When we debug a switch, the switch displays the details of each port in sequence, this includes port disconnections and explains the accumulated information. Cisco is the main force in the entire vswitch. Its products are doing very well in the market. The following article will detail some of the usage skills and precautions of Cisco switches, in many organizations, the core bac

In some low-end switch markets, layer-3 switching has gradually become the mainstream in the market. Its biggest difference is that it integrates the advantages of layer-2 switches and layer-3 routers, in this way, the line speed performance can be provided at all levels. This integrated structure also introduces policy management attributes, which not only associate Layer 2 with Layer 3, but also provides traffic prioritization, security, and a varie
