network isolation switch

. Although the current long-distance telephone exchange network structure has reached a certain scale, there are enough connections between the nodes, but how to make the business and traffic flow in the network orderly and efficient flow, and according to the network situation reasonable use of circuit resources, has become

When the main performance of a LAN cannot meet the new application requirements of an enterprise, you must consider upgrading the network. During the upgrade, you should analyze the problems to be solved based on the requirements of network applications, especially the upgrade of switch hardware devices. This article will discuss this issue with you. Upgrade

With the development of China's exchange industry and the promotion of updates and upgrades of the soft switch technology, we mainly analyze the development relationship between the soft switch technology and the Next Generation Network. Over the past few years, with the rapid popularization and maturity of domestic IP phone technology and successful market opera

An improper port connection between switches in Ethernet can cause network loops, and if the associated switch does not have STP enabled, the loop triggers endless repetitive forwarding of packets, creating a broadcast storm that causes network failures. one day, we found a problem with the VLAN in the network runnin

The exchange network technology is still quite common, so I have studied the types of the exchange network technology and the precautions in the application. Here I will share with you, I hope it will be useful to you. In 1993, LAN switching equipment emerged. In 1994, the exchange network technology boom began in China. In fact, the exchange

level products. Cisco and 3Com are still the leader in market share, Atrica, Extreme, foundry and Nortel have also introduced technology-leading and performance-friendly products, and Intel and other manufacturers have introduced low-end but superior performance products. Huawei introduced the S8016-type high-end routing switch in 2001, with a back-panel capacity of up to 256Gbps. The products of each section flourish Cisco offers a Catalyst series

Slow network speed is a common type of switch failure. We need to carefully analyze the error records of the faulty switch so that we can fundamentally solve the problem and avoid repeated errors later. When the network scale is relatively large, the "load" of switches that shoulder

Reasonable configuration solves the problem of Switch network loop, in the way of judging switch network loop, this paper makes a preliminary analysis of switch network loop problem from log information and enabled state, then rat

August 2012, the current network use of a ZTE 2826 switch can not remote Telnet logon situation, ping switch network management IP address serious packet loss. The process is probably as follows: 1, the site through the console port login switch to confirm the normal equipm

The configuration of a vswitch has always been mysterious, not only for general users, but also for the vast majority of network administrators. It is also an important and basic indicator for measuring the level of network management. This is mainly due to two reasons: first, the switches configured by the vast majority of enterprises are non-Network-connected v

There are many things worth learning about the switch system. Here we mainly introduce how to reasonably configure the switch so that the switch system can control the network at will. With the rapid development of information technology, many organizations have established their own internal networks to cater to the i

level products.

Virtual switches in Hyper-V if you have studied VMware virtualization, the virtual switches in them are fundamentally different, so let's briefly talk about the three virtual switches for Hyper-V network virtualization.For child shoes that are just touching hyper-V, a virtual switch may make you feel a bit more headache, first of all, Hyper-V will not bring any created virtual switches and virtual

Lan exchange technology can also be called layer-2 Switch Exchange Technology, the content mainly includes the working principle of Layer 2 switching, network loops, and how to use the Spanning-Tree Protocol to solve Network loops, VLANs, and VTP technologies, this article mainly introduces the working principle of L2 switches and the dangers of

When the main performance of the LAN can not meet the new application requirements of the enterprise, we must consider to upgrade the network. Upgrade should be based on the needs of network applications, analysis of network upgrade to solve the problem, in particular, upgrade the switch hardware equipment, this articl

Undeniably, the establishment of a local area network, security is essential. Let H3C's "fortress" to help you stop the virus attack! Don't get me wrong, we're not talking about firewalls, but building H3C gigabit secure LANs: S5500-si and S5120 series switches. As a family member of Gigabit Network, in addition to the small and medium-sized office network to br
