Perform full resolution on Cisco Ethernet switch policies

The Cisco Ethernet switch is also available on the Interface 3 ~ After about four years, his own drivers are constantly updated, and his stability and security have also changed.

In China, as an important part of network infrastructure, vswitches have a huge market demand and competition among manufacturers is becoming increasingly fierce. With years of understanding of the network product market and leading technology, Cisco has created an image of a switch market leader.

Three major market factors

Cisco believes that informatization in various industries in China is developing at an unprecedented speed. Regardless of their size, enterprises take information processing and network communication systems as their strategic infrastructure and production tools, in order to improve production efficiency and further promote the improvement of enterprises' core competitiveness, better cope with the new situation of opening up the market after entering the WTO.

To carry out information construction, a complete information network system should be established to support applications such as CRM, ERP, and SCM, so that enterprises can make full use of various resources and expand the market, remain undefeated in the competition. As a core switch of the Enterprise Information Network, vswitches have attracted much attention.

Based on this, Cisco believes that the development trend of China's network is to integrate data, voice, video, storage and other applications across the entire network platform to support more and more applications. Network technology is evolving towards integrated application. switches need to support integrated transmission of data, voice, and images. That is to say, the development of Cisco Ethernet switches requires the following three factors.

First, network applications and convergence. Services based on the internal network and Internet of enterprises have been gradually launched in many enterprises. Many enterprises have begun to deploy enterprise resource planning (ERP), Customer Relationship Management (CRM), Supply Chain control, and other types of systems to achieve higher productivity through the network.

However, with the continuous improvement of IT infrastructure and the continuous expansion of applications, an indisputable fact is that an enterprise has a complicated and huge information system, analog data of telephone, fax, and video types and enterprise data are transmitted by independent network infrastructure.

Second, intelligent response to the new challenges of enterprise networks. The development of enterprise networks is facing new challenges. The most obvious change is that when users select Network Solutions, they are very different from the past, they no longer put forward too many demands from the network technology aspect, but first explained what problems should be solved and what applications should be supported to build the network.

When building a network, users not only pay attention to the network infrastructure, but also pay more attention to what can be done after the network is built. In the past, we focused on the technical aspects and proposed such a technology. Now, in turn, we are more application-oriented. When users choose solutions and products, they are more concerned about how to ensure the benefits of investment.

Finally, QoS and security are critical. Intelligent Enterprise Network includes a lot of content, including QoS and security. QoS is very important for converged networks and key applications, and the development of broadband applications also promotes QoS requirements.

Today, QoS is no longer simply 802.1 p, but a comprehensive system of 802.1p and many other new technologies. To fully support various applications on a vswitch, complete QoS is essential, including a series of processes such as traffic classification, inbound and outbound bidirectional monitoring, shaping, and scheduling.

In general, QoS maximizes the effective application of network bandwidth. Security includes system security and access security. As people pay more and more attention to security, it is becoming more and more important to integrate basic elements of security into network infrastructure.

Sijun Qi, Tianxia chengping. This sentence describes the capabilities and contributions of the four famous swift horses. Cisco Ethernet switches, mainly including Catalyst 2950, 3550, 4000/4500, 6500, And, form a strong lineup of all Cisco Ethernet switches. In terms of the title of qianjima from ancient times, we have compared the products of these series to the four horses-jun, Jun, Lu, Hua, and Yao.
The Catalyst 2950 series smart Ethernet switch is a fixed configuration, stackable standalone device series that provides fast line-rate Ethernet and Gigabit Ethernet connections, providing smart services for medium-sized networks and Metro access applications. The 2950 series provides intelligent service quality (QoS), speed limit, access control list ACL), and multicast services in the wiring room;

Provides a powerful path to upgrade to Gigabit Ethernet on a variety of media, with its built-in Cisco cluster management suite to manage and configure 2nd ~ Layer-4 service. For man, its access advantage is that it provides a wide range of services through advanced QoS, speed limit, voice and multicast features, and improves the access control parameters through Spanning Tree Protocol ACP) to provide service availability and security, and implement service management through the Cisco IE 2100 series Intelligent engine and Simple Network Management Protocol SNMP.
