56.3.1 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 ISG50 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.
Figure 503 Maintenance > Diagnostics > Packet Capture > Files
The following table describes the labels in this screen.
Capture Click this button to have the ISG50 capture packets according to the
settings configured in this screen.
You can configure the ISG50 while a packet capture is in progress although
you cannot modify the packet capture settings.
The ISG50’s throughput or performance may be affected while a packet
capture is in progress.
After the ISG50 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.
