Configuring WLAN sniffer
In a wireless network, it is difficult to locate signal interference and packet collision by debugging
information or terminal display information of WLAN devices. WLAN sniffer facilitates the
troubleshooting by using an AP as a packet sniffer to listen to, capture, and record wireless packets. The
information about captured packets is stored in a CAP file.
As shown in
Figure 96 , enable WLAN sniffer on the Capture AP. The Capture AP listens to the wireless
packets in the network, including the packets from other APs, rouge APs, and clients, and stores the
captured packets in the specified CAP file. The administrator can download the CAP file to a PC for
analysis.
