DESCRIPTION
Click this to go the Configuration > Wireless > AP Management screen, where
you can set one or more APs to monitor mode.
This column displays which APs on your wireless network are currently configured
for monitor mode.
Use the arrow buttons to move APs off this list and onto the Captured MON Mode
APs list.
This column displays the monitor-mode configured APs selected to for wireless
frame capture.
Specify a maximum size limit in kilobytes for the total combined size of all the
capture files on the ZyWALL/USG, 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 ZyWALL/USG stops the capture and generates
the capture file when either the file reaches this size.
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 ZyWALL/USG capture frames according to the settings
configured in this screen.
You can configure the ZyWALL/USG while a frame capture is in progress although
you cannot modify the frame capture settings.
The ZyWALL/USG's throughput or performance may be affected while a frame
capture is in progress.
After the ZyWALL/USG 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.
