lan switching technologies ccna

It can be said that at present, LAN switching technology has become one of the core technologies of the new era. Here we have analyzed the basic concepts and practical application of LAN switching technology. In the past few years, fundamental changes have taken place in the

switching technology, layer-4 switching has emerged. It expands layer-3 and layer-2 switching, supports more fine-grained network adjustment, and gives priority to communication streams. The layer-4 switch is a policy-based route. It is located on the layer-4 of the ISO Reference Model and uses the layer-4 information. According to the layer-4 Information, for e

Compared with other network management technologies, the multi-layer switching technology has distinct characteristics. Here we mainly analyze the advantages of multi-layer switching technology, so that you can have a deeper understanding of it. With the rapid development of Internet/Intranet deployment and usage, the computing models of enterprises and consumers

development status is satisfactory. Therefore, the focus of selection is not at this level. However, as the core of the network, there is no substantial breakthrough in the router technology that acts as the interconnection between networks. Therefore, a new routing technology came into being-layer-3 switching technology, which is a routing technology because it works on the layer-3 network protocol, the two-layer

In the past, vrouters and hubs were often used in the network, but now many networks use vswitches. How do I face the challenges of routing networks and switching technologies? Currently, vswitches are dominant in the network market, because of their high cost effectiveness and flexible structure. They can be flexibly configured with future application changes. Numbers can best indicate problems. In a vswit

Now, the Internet industry is no stranger to the word "layer-3 switching". In medium and large scale network construction, there are no more mainstream network models with gigabit layer-3 switches as the core. In fact, the emergence of layer-3 switching from its emergence to today's widespread application is just a few years ago, the rapid development of the computer network acceleration momentum, it is ama

only receives a frame with a source address of AA-AA-AA-AA-AA-AA on the port port1/2 and then changes its top Mac forwarding Address table entry to the wrong port! As the frame spins in the opposite direction (recalling that loop forwarding exists in two directions), you will see that the MAC address of the HOST-A will beswitch back and forth between Port 1/1 and Port 1/2. in short, not only the unicast ping package will continue to fill the entire network, and the bridge MAC address forw
