The main network technology we currently use when constructing an enterprise network is generally based on exchange and virtual networks. The exchange technology changes shared media to exclusive media, greatly improving the network speed. The Virtual Network Technology breaks the restrictions of the geographical environment. without changing the physical connection of the network, the wo

The introduction of vlan of a Huawei switch and three VMPS modes. In the explanation of vlan of a Huawei switch, there are three VMPS modes (but User Registration Tool, namely URT, only supports open mode ). How to configure dynamic vlan and VMPS of a CATALYST 4500 series switch? This article takes cisco ios 12.2 (31) SGA as an example.

In fact, the essence of a layer-3 switch is a layer-2 switch with the routing function. The routing mainly belongs to the network layer function in the OSI reference model, so the layer-3 Switch also has the routing kinetic energy. Now, we know that computers with different VLANs can communicate with each other as long as they can provide routes between VLANs. However, if a router is used for inter-VLAN routing, as the traffic between VLANs increases,

VLAN (virtual LAN), translated into Chinese is a "virtualized local area network". The physically connected network is divided into a plurality of logical independent virtual subnets, originally, the second layer switch can only build a single broadcast domain, but with the VLAN function, it can divide the network into multiple broadcast domains.The switch allows the LAN to be divided into multiple VLANs, a
1. Networking requirements: 1. switchA and SwitchB use trunk for interconnection. Mutual access is allowed between PCs with the same VLAN. Mutual access is prohibited between PCs with different VLANs. PC1 and PC2 are located in different VLANs. You can set the IP address of VLAN Interface 10 of the SwitchB layer-3 Switch to 10.1.1.254/24, when the IP address of VLAN
