Remote Packet Capture
The Remote Packet Capture feature enables you to specify a remote port as the
destination for packet captures. This feature works in conjunction with the
Wireshark network analyzer tool for Windows. A packet capture server runs on the
WAP device and sends the captured packets through a TCP connection to the
Wireshark tool. Wireshark is an open source tool and is available for free; it can be
downloaded from
http://www.wireshark.org
.
