cisco switch vlan commands

A typical case of cisco VLAN configuration has seen some exchanges on the Internet. The vlan configuration is vague. I want to help my siblings by sorting out the information. Two switches and two Router Vlan test devices: two switches, two 2950 routers, and one 2620 test equipment. Two switches are required. Switch1 a

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:

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

for Route Selection and forwarding. Layer-3 switches use direct connection routes to achieve mutual access between different VLANs. Layer-3 switches configure IP addresses for interfaces and use SVI (exchange virtual interfaces) to interconnect VLANs. SVI refers to creating virtual interfaces for VLANs in a vswitch and configuring IP addresses. Iv. Experiment steps Lab Topology 1. Configure VLAN 2 and

is based on the OSI Layer 2. Configure the relay mode on the ports that are interconnected between vswitches or between vswitches and vrouters (the Trunk port is a relay port, and the Trunk must be set when different VLAN information is transmitted on the same port ), this enables data frames belonging to different VLANs to be transmitted through this relay link. There are two types of frames: * ISL: Inter-Switch
