Click Maintenance > Diagnostics > Wireless Frame Capture > Files to open this screen. This

to your computer where you can study them using a packet analyzer (also known as a network or
protocol analyzer) such as Wireshark.

DESCRIPTION
Specify a maximum size limit in kilobytes for the total combined size of all the
capture files on the NXC, including any existing capture files and any new capture
files you generate.
Note: If you have existing capture files you may need to set this size larger or delete
existing capture files.
The valid range is 1 to 50000. The NXC stops the capture and generates the capture
file when either the file reaches this size or the time period specified in the Duration
field expires.
Specify text to add to the front of the file name in order to help you identify frame
capture files.
You can modify the prefix to also create new frame capture files each time you
perform a frame capture operation. Doing this does no overwrite existing frame
capture files.
The file format is: [file prefix].cap. For example, "monitor.cap".
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.
Click this button to stop a currently running frame capture and generate a combined
capture file for all APs.
Click this button to return the screen to its last-saved settings.
