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 net-work 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.
