The information in this document was created from the devices in a specific lab environment.
Prerequisites RequirementsĬisco recommends that you have knowledge of these topics: If you make the capture on an open SSID (no security), you are able to see content of the data packets but if the client is associated to a secured SSID (a password protected SSID or 802.1x security) then the data portion of the data packets is encrypted and cannot be seen in clear text.įeature is only available for IOS APs (Like AP 3702). If the client moves between Service Set Identifiers (SSIDs), the AP does keep the packet capture alive so you can see all the management frames when the client associates to the new SSID.
If the client roams, the new AP creates a new. pcap file on the FTP server (ensure the username specified for FTP login has write rights). Once the packet capture is started, the AP where the client is associated to, creates a new. pcap file and open it with your preferred packet analysis tool. When the feature is enabled, a copy of all the specified wireless packets and frames sent and received from/to APs from/to a specific wireless mac address over the air, is forwarded to a File Transfer Protocol(FTP) server, where you can download it as. Background InformationĪP Packet Capture feature allows you to perform packet captures over the air with little effort.
This document describes how to use the Access Point (AP) Packet Capture feature.
