摘　　要：无线局域网于公共场景中得到广泛应用,以满足用户的上网需求.针对无线局域网中的漫游现象,设计了一个通过旁挂方式接入到控制器的无线局域网漫游的仿真实验.采用eNSP作为网络仿真平台,以无线局域网中的二层和三层漫游为例,给出了在接入控制器上的重要配置.通过利用Wireshark工具进行抓包,对数据包进行分析,从而对实验结果进行验证.结果表明,该实验直观地呈现了无线终端在AP之间切换的过程,捕获的数据包充分表明了无线漫游的过程,具有良好的实验示范效果.Aiming at the problem of WLAN roaming,a simulation experiment was designed,which was connected to the controller through a side mounted method.The eNSP simulator was used as the network simulation platform.Taking layer 2 and layer 3 roaming in wireless local area network as examples,important configurations on access controllers were provided.The packets were captured by using the tool named Wireshark,and the experiment results can be validated by analyzing the packets.The results showed that the process of the wireless terminal switching between APs was visually presented,and the process of wireless roaming was fully demonstrated by the packets which were captured.
