摘　　要：在二层网络里,由于接入终端数量较大,形成的广播域也很大,一旦发生广播风暴,会造成二层网络拥塞、垃圾流量过多等现象,严重影响全网的终端上网功能。在网络规划时使用VLAN技术控制广播域的范围,减少广播风暴的影响范围,提高网络性能是目前较常用、较规范的设计方法。文章介绍VLAN技术的相关内容,并将二层接入网络增加VLAN设计进行改造,并结合DHCP技术使终端上网方便,且减少了网络风暴的影响,取得了很好的使用效果。In the layer-2 network,due to the large number of access terminals,the formation of the broadcast domain is also very large.Once a broadcast storm occurs,it will cause the congestion of the layer-2 network,excessive garbage flow and other phenomena,which seriously affect the internet access function of the whole network.Using VLAN technology in network planning to control the scope of the broadcast domain,reduce the scope of influence of broadcast storms,and improve network performance is currently a more common and standardized design method.This paper introduces the related content of VLAN technology,and adds VLAN design to the layer-2 access network for transformation.Combined with DHCP technology,it makes the terminal convenient to access the internet,and reduces the impact of network storm,and achieves good results.
