7.3.1  Packet Capture Files Screen

Click 

Maintenance > Diagnostics > Packet Capture > Files

 to open the packet capture files screen. This 

screen lists the files of packet captures stored on the NSG or a connected USB storage device. 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.

Save data to USB 
storage 

Select this to have the NSG store packet capture entries only on a USB storage device 
connected to the NSG if the NSG allows this. 

Status:

Unused

 - the connected USB storage device was manually unmounted by using the 

Remove Now

 button or for some reason the NSG cannot mount it.

none

 - no USB storage device is connected.

service deactivated

 - USB storage feature is disabled (in 

Configuration > Object > USB 

Storag

e), so the NSG cannot use a connected USB device to store system logs and other 

diagnostic information.

available

 - you can have the NSG use the USB storage device. The available storage 

capacity also displays.

Note: The NSG reserves some USB storage space as a buffer.

Capture

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

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

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

After the NSG 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.
