Click Maintenance > Diagnostics > Packet Capture > Files to open the 
packet capture files screen. This screen lists the files of packet captures the 
ZyWALL 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. 

Figure 572   Maintenance > Diagnostics > Packet Capture > Files       

The following table describes the labels in this screen.  

Capture

Click this button to have the ZyWALL capture packets according to 
the settings configured in this screen. 

You can configure the ZyWALL while a packet capture is in progress 
although you cannot modify the packet capture settings.

The ZyWALL’s throughput or performance may be affected while a 
packet capture is in progress.

After the ZyWALL finishes the capture it saves a separate capture 
file for each selected interface. The total number of packet 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 packet captures will fail.

Stop

Click this button to stop a currently running packet capture and 
generate a separate capture file for each selected interface. 

Reset

Click this button to return the screen to its last-saved settings.
