Today, the tutor told me about the company's network topology, related to the switch, the basic concept of routers and principles, I am not very clear, so on the internet to learn the information to learn a bit, and then feel that this article is good, so it reproduced, but I reproduced not the original text, and did not attach the original link. Here I posted a link to my reprinted article: http://blog.csd

the whole network of MAC address information can be learned, the two-tier switch is to build and Maintain its own Address table. The following three points can be inferred from the working principle of the two-layer switch: (1) because the switch to the majority of port data exchange, this requires a very wide exc

their mutual connections may vary depending on the environment, the routing information is usually updated as specified in the Routing information protocol used. Main difference: The two-tier switch works at the data link layer, the three-tier switch works at the network layer, and the router works at the network laye

IntroductionTraditional routers have isolated networks, isolated broadcasts, routing and forwarding, and firewall operations in the network, and as the network continues to evolve, the load of routers is growing rapidly. One of the important reasons is that the VLAN (virtual local area network) technology is widely used in networks because of security and managem

Many vswitch users have encountered many problems due to many reasons. Here we mainly analyze the vswitch network faults caused by incorrect Switch location installation. A vswitch is a key connection device in a LAN. It has a large number of vswitches in a LAN. In such a network environment, the administrator needs to reasonably deploy the vswitch based on its p

administrative IP address in dotted quad format (nnn. Nnn. Nnn. Nnn): // press "nnn. Nnn. Nnn. Nnn "format input IP Address Current setting ==> 0.0.0.0 // the IP address before the switch is not configured is "0.0.0.0", representing any IP Address New setting ==> // enter a New IP address here If you want to configure the subnet mask and default gateway of the vswitch, select "S" and "G" on the IP configuration page. Now let's take a look at the Pass

Normally, when 3G and WiFi are on, Android uses Wi-Fi by default, but it is not possible to have WiFi everywhere in the real world, so the phone will often automatically switch networks.Sometimes, when the phone starts using WiFi, it will automatically switch from WiFi to 3G network 10-30 minutes after it enters standby.If you write a

It is believed that most network administrators usually move back and forth between different working subnets, but when performing network management and maintenance operations in a different working subnet environment, network administrators often need to constantly modify the laptop's Internet access parameters so that the laptop can be quickly connected to the

Company for business needs, commissioning network Netgear GS728TP Poe switch, Partition VLAN and other services, after all debugging is complete. Again habitually save restart the device. Results after this reboot. The inexplicable wonderful ping does not pass the address of the management switch. Not to mention using a Web interface to manage the

Netmap to VALE-from high-performance network framework to High-Performance Virtual Network Switch, netmapvaleAs mentioned in the previous article, for full virtualization and semi-virtualization, a virtual network interface needs to be assigned to the virtual machine, which requires a vswitch (which can be used togethe

Overview: Currently there are seven kinds of network card binding mode (0~6) bond0, Bond1, Bond2, Bond3, Bond4, Bond5, Bond6 There are three kinds of commonly used: Mode=0: Balance load mode, there is automatic backup, but need "Switch" support and settings. Mode=1: Automatic standby mode, if one line is disconnected, the other lines will be automatically prepared for assistance. MODE=6: Balanced load mode

The configuration of network management switch has always been fascinated by many people, not only for the general users, but also for many professional users, but also as an important and basic indicator of the level of network management. this is mainly in two reasons, one is the vast majority of enterprises configured switches are desktop non-

Article title: the network management tool allows the network card to switch freely on the hand. Linux is a technology channel of the IT lab in China. Includes basic categories such as desktop applications, Linux system management, kernel research, embedded systems, and open source. In many cases, you need to enable or disable the Nic device. In most cases, you n

The IDC report shows that the switch market has maintained a high growth momentum in recent years, and the market is expected to reach $1.51 billion by 2009. Switch in the enterprise network occupies an important position, is usually the core of the entire network, this position makes it become the focus of hacker intr

The IP address of a CEN user is 10.0.0.2/24 and is connected to the Internet through a Switch. Switch is the carrier device. Enterprise Network users only rent 1 Mbps upstream bandwidth and 2 Mbps downstream bandwidth.Figure 1 General CAR configuration networking Configuration ideasTraffic Monitoring is implemented through QoS command lines. In this case, the us

In the LAN working environment, encounter network virus attack is always unavoidable things, once the workstation accidentally infected with the network virus, then it can not be normal access to the Internet; In addition, users to change the IP address at will, the local area network is prone to the phenomenon of IP address conflict, once such a failure occurs,
