Click Maintenance > Diagnostics > Wireless Frame Capture > Files to open this screen. This screen lists the
files of wireless frame captures the NXC has performed. You can download the files to your computer
where you can study them using a packet analyzer (also known as a network or protocol analyzer) such
as Wireshark.

The following table describes the labels in this screen.
Capture Click this button to have the NXC capture frames according to the settings configured
in this screen.
You can configure the NXC while a frame capture is in progress although you cannot
modify the frame capture settings.
The NXC’s throughput or performance may be affected while a frame capture is in
progress.
After the NXC finishes the capture it saves a combined capture file for all APs. The total
number of frame capture files that you can save depends on the file sizes and the
available flash storage space. Once the flash storage space is full, adding more frame
captures will fail.
Stop Click this button to stop a currently running frame capture and generate a combined
capture file for all APs.
Reset Click this button to return the screen to its last-saved settings.
