Layer-3 Ethernet switch: introduces L2 VLAN forwarding, configurations in layer-3 Ethernet switches, MAC addresses, and L2 VLAN forwarding, I hope you will have a clear understanding after reading the following articles. The forwarding mechanism of a layer-3 Ethernet switch is divided into two parts: layer-2 forwarding

physical network and geographical location. A virtual workgroup can contain departments and workgroups in different locations, without having to physically reconfigure any ports to actually implement network users regardless of their physical location. The virtual network technology divides the traditional broadcast domain into each independent sub broadcast domain, restricts the broadcast to the virtual workgroup, because of the reduction of broadcast domain, the proportion of broadcast packet

security. Therefore, the use of VLAN in the initial design of the network can bring great benefits to the future expansion of the network.VLAN partitioning by routers is a cost-effective method in small and medium-sized enterprises. However, VLAN partitioning by routers seriously affects the network performance of enterprises, therefore, layer-3 switches with routing functions are widely used in

The article I want to share and configure VLAN on Linux through Cisco Catalyst Switch.Requirements:1. Linux installed on a PC with one or more NICs (Network Interface Card). I Use the Centos 5.4 using 2.6.18-164.11.1.EL5PAE kernel. It should is applicable on other Linux distros such as Slackware, Ubuntu, Fedora, Debian, etc.2.

client, the switch can be configured completely. If you think that the management port is inconvenient, you can set the management IP address of the switch, turn on telnet or Http/https connection, and manage it through the LAN connection switch. The configuration command for a switch has a hierarchy and is a comm

Enable the VMware ESXi virtual switch to support VLAN Currently, virtualization is widely used. Generally, a physical host can create multiple virtual machines on a physical host after installing VMware ESXi or Hyper-V Virtual Machine Software, in addition, each created virtual machine can provide external services like the original physical machine, which can undoubtedly make full use of server resources t

There is an existing Huawei s5700 switch and a number of ordinary switches, as well as a tp-link router. The 1.tp-link router connects to the extranet. The 2.s5700 switch divides the VLAN. 3. Normal switch is connected to VLAN and PC side. The network topology diagram is as

An example of how to configure an ACL to ensure the VLAN security of a vswitch. I would like to introduce the VLAN security problem of a vswitch to you. Many people may not understand the VLAN security problem of the vswitch. It does not matter. After reading this article, you will surely have a lot of GAINS, I hope this article will teach you more things. As you

The emergence of Virtual lan vlan breaks the many inherent concepts of traditional networks, making the network structure flexible, convenient, and free to do as you like. VLAN divides user logic into working groups with relatively independent functions based on functions, applications, and other factors without considering users' physical locations, each user host is connected to a

Full solution D-LINK Switch configuration in the enterprise network VLAN subnet usage, on the D-LINK Switch configuration problems, from the following aspects: from the enterprise network plan four VLAN subnet classification and structure, DES-3326SR Switch configuration pro

Lab Requirements:The dual-core architecture combines three-layer switching technology with VTP, STP, and Ethernet channels to achieve high-speed network conversion, high availability, high reliability and redundant backup functions, mainly for the network of dual-core topologies.Experimental design:1. Configure VLANs on the switch to control broadcast traffic.2. Configure the Ethernetchannel between the 2 three-layer switches to achieve high-speed int

1. Background Generally implement VLAN communication, or use a three-tier switch, or a single arm routing, both of which are very expensive, so when there is the need for VLAN communication, and the data volume of the VLAN communication is not very large, with 50 of Soho route to build a network is very affordable.

In the composition of wireless networks, the use of many devices deserves a detailed understanding. Today we will talk about the failure of VLAN wireless Internet access switches. The following is an experience shared by a netizen: A strange problem occurs in the VLAN of the two departments where an office area is located. Some websites on the Internet can be accessed normally, but some websites cannot; ema

vswitches have this function. Only vswitches above Layer 2 of the VLAN Protocol have this function. The emergence of 802.1Q standards breaks the deadlock that virtual networks depend on a single vendor, and promotes the rapid development of VLANs from one side. 2. vswitch port working mode The switch port has three working modes: Access, Hybrid, and Trunk. An Access port can only belong to one
