40.3.1 The 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 Zyxel Device 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 Zyxel Device store packet capture entries only on a USB storage
device connected to the Zyxel Device if the Zyxel Device allows this.
Status:
Unused
- the connected USB storage device was manually unmounted by using the
Remove Now
button or for some reason the Zyxel Device cannot mount it.
none
- no USB storage device is connected.
service deactivated
- USB storage feature is disabled (in
Configuration > System > USB
Storag
e), so the Zyxel Device cannot use a connected USB device to store system logs
and other diagnostic information.
available
- you can have the Zyxel Device use the USB storage device. The available
storage capacity also displays.
Note: The Zyxel Device reserves some USB storage space as a buffer.
Save data to ftp server
(available: xx MB)
Select this to have the Zyxel Device store packet capture entries on the defined FTP site.
The available storage size is displayed as well.
Server Address
Type the IP address of the FTP server.
Server Port
Type the port this server uses for FTP traffic. The default FTP port is 21.
Name
Type the login username to access the FTP server.
Password
Type the associated login password to access the FTP server.
Capture
Click this button to have the Zyxel Device capture packets according to the settings
configured in this screen.
You can configure the Zyxel Device while a packet capture is in progress although you
cannot modify the packet capture settings.
The Zyxel Device’s throughput or performance may be affected while a packet capture
is in progress.
After the Zyxel Device 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.
