摘要
河南电力调度交换网需要传输视频和网管信息,因此,加入了网络交换机组网的视频网络。视频网络起初未划分VLAN,容易产生广播风暴。为消除隐患,对其进行了VLAN改造。文章介绍了VLAN原理及划分规则,并结合业务类型和网络现状提出了适合三层交换机端口划分和网络VLAN划分方案。
To meet the need of video data and network management data transmission, the video network constructed by network switches is connected with Henan electric power dispatching exchange network. Initially the video network easily leads to the broadcast storm because of no division of VLAN. To solve this issue, there is a need to transform the existing VLAN. This paper describes the principles and division rules of VLAN and proposes a division method suitable for VLAN with configuration schemes of three layer switch ports by taking service types and network situation into account.
