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

Cisco single-ARM routing configurationOne-arm routing, which is to set up multiple logical subinterfaces on the router, one VLAN for each sub-interface. The data on each sub-interface is passed on the physical link to be labeled encapsulated. Cisco devices support ISL and 802.1q (dot1q) protocols. Huawei only supports 802.1q.The difference between dot1q and ISL:

Many SME internal network structures are simple, with only one switch connecting all employees and servers together and then accessing the Internet through fiber optics. Of course, in order to ensure the security of some hosts and split the internal broadcast packet to improve the network transmission speed, take such as partition VLAN, the allocation of different subnets to achieve. By partitioning VLANs,

Recently, a number of Cisco ucs c Series servers have been added. After two weeks of deployment and installation, the server can finally be tested. This document briefly introduces the network configuration of the Operating System (centos 6) in the Cisco UCS server. It can be simply considered that this article describes the network configuration of a physical server connecting the NIC to the trunk mode por

isolated from the rest of the network, thereby reducing the likelihood of disclosing confidential information. Messages in different VLANs are isolated from each other during transmission, and different broadcast domains want to communicate between them and need to pass through one or more routers. VLANs can divide a second layer of planar networks into multiple logical workgroups (broadcast domains) to reduce unnecessary traffic on the network and improve performance. Experimental topological

Cisco router configuration manual Virtual LAN (VLAN) routing 1. 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 t

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

Huawei s5700 switch vlan settingsCurrently, there are several Huawei s5700 switches, common switches, and tp-link routers. 1. The tp-link router connects to the Internet. 2. The s5700 switch divides vlan. 3. Common switches are connected to VLANs and PCs. The following figure shows the network topology. The s5700 has a

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 to save power and space. But when most of our friends use virtual machines, there is also a problem:
