how to create vlan in cisco switch

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

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 un

During hard disk data sorting, we found the original dtp vlan jump experiment video, which includes DTP protocol data packets, test tools, videos, and lazy. The following are the steps. Download the video and watch it. It was very casual. At that time, I kept it for reference. Implementation of VLAN jump attacks I don't talk much about it. I only find such a term on the Internet. No one has told me the

In the wireless network composition, the use of a lot of equipment is worth a detailed understanding. So today we're going to talk about the problem of VLAN wireless internet switch failures. The following is a netizen's experience sharing: Unit one office area where the two departments VLAN appeared a very strange problem, some websites on the internet can be no

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

interconnected with layer-3 switches. When using a router to connect to a vrovlan, you generally need to set sub-interfaces corresponding to each VLAN on the LAN Interface, while a layer-3 Switch generates a "VLAN Interface" internally )".

Today, we introduce some common basic operations of Cisco devices, such as creating VLANs, binding network cables, doing trunks, using three-layer switching, and so on.This is today's topology diagram: Two three-layer switching, two PCs, respectively, add vlan10 and 20, two three layers to do network redundancy, and finally achieve two PC communication, very simple, but the use of an experiment:650) this.width=650; "src=" http://s3.51cto.com/wyfs02/M0

VLAN overviewVirtual LANs are a logical group of users who are linked on physical devices that are not subject to physical location restrictions.Reference VLAN:The switch divides the conflict domain, but cannot divide the broadcast domain, as the number of switch ports increases, the broadcast in the network increases, the network efficiency is reduced, and the
