Analyzes the security firewall built in the gigabit network switch, and implements the Gigabit line rate switching by using the proxy plug-in of the gigabit network switch application service. The built-in security firewall will also be a highlight of gigabit network switche

For a growing company, effective communication is as important as the strong business planning of capital operations. But at the moment, small and medium-sized businesses and affiliates are still at a high point when it comes to corporate phone systems. The advent of the network telephony switch has changed this situation. The traditional telephone switch uses t

The switch is the most important network connected device of LAN, and the management of the LAN mostly involves the management of the switch. However, many campus network network management on the switch configuration is still ver

How to quickly resolve switch faults and effectively improve network efficiency. Please refer to this article for details: 1. Solve the trouble of resetting VLAN When managing and maintaining a LAN, if the cascade port connecting to a common switch changes, the VLAN previously configured in the switch system may not w

The network switch technology allows you to adjust the shared and dedicated LAN segments, which effectively reduces the information flow bottleneck in the LAN and ensures the security and stability of our network. In 1993, LAN switching equipment emerged. In 1994, the domestic network

Friends, have you ever been in a situation where your network is slowly pausing, yet all switch ports are sending data continuously. You must have a feeling that the network Computer workException, and may even have suffered an attack. What are you going to do about it? The author believes that the first step requires you to open the

act as a route. It is a switch because it is extremely fast, almost reached the second-level switching speed. This is also the topic of this Article. What is layer-3 switching technology. Let's first introduce the OSI model, which is widely recognized as the Open System Interconnection Model OSI of the International Organization for Standardization (ISO). It is a hierarchical network architecture, divide a

As a core network terminal in a LAN, maintaining the switch system becomes very important. In order to make the LAN work more stably, we often need to properly adjust the switch to ensure that the device can always run efficiently. Regular upgrades keep vswitches alive I have encountered a frequent network interruption

At present, China's route switch equipment is developing very rapidly, and it is also more important in the development of the network, it also promotes the upgrade of routing technology. Traditional route switches are mainly used for Fast Packet forwarding, with emphasis on forwarding performance. With the wide interconnection of LAN and the openness of TCP/IP protocol,

the network, and the reported traffic is only 5 MB. It seems that not only 45 MB of traffic is filtered out by the channel, but also a great delay is introduced. Check the topology of the website. The figure shows that the access channel is a Mbps Ethernet link, and five switches are used in the middle to reach the server. Perform the "TraceSwitch" check on the vro in OptiView. The result shows that the path has changed! Three more switches are inclu

In order to improve the LAN operation and maintenance efficiency, we need to accumulate various switch troubleshooting experience at ordinary times so that the switch can be quickly rectified in case of a fault, this article has contributed several vswitch troubleshooting skills to my friends. I hope these content will help you! 1. Solve the trouble of resetting VLAN When managing and maintaining a LAN, if

Ethernet Switch by enterprise Application network is mainly divided into two categories, one is to use the protocol converter to switch to Ethernet access switches, the second is to rent bare fiber directly. Specifically, the three-tier switch selected in 三、四级 network can on

1. Login 192.168.1.1 (router default IP address, with the network cable configured to connect to the LAN port) into the router settings Point LAN port Settings, the IP address to the switch with a network segment of the IP address (192.186.118.100), modified to save, restart the router into effect. 2. Select a DHCP server: Select the DHCP service,

There are many things worth learning about Ethernet switches. Here we mainly introduce Ethernet switch configurations and network types. Rack-mounted switch, fixed configuration with/without expansion slot) rack-mounted switch is a slot type switch, which has good scalabilit

Master the high-end switch cascade to instantly become a master of the network, previously introduced the relevant knowledge. After the publication of the stack and cascade of switches, we have received a number of emails from many readers to discuss with us about the cascade of switches. So we will introduce some related content about high-end switch cascade. Hi

Managing the vswitch configuration file is still very important for users, but many users still do not pay much attention to it. This is very dangerous and their networks will also have security risks. The configuration file is the core of Cisco network devices. The configuration file is like the Registry file of the operating system. If the registry is damaged or the configuration is inaccurate, the operating system cannot be started or run stably. I
