Packet Capture
Sometimes when you contact IronPort Customer Support with an issue, you may
be asked to provide insight into the network activity going into and out of the Web
Security appliance. The appliance provides the ability to intercept and display
TCP/IP and other packets being transmitted or received over the network to which
the appliance is attached.

You might want to run a packet capture to debug the network setup and to discover

what network traffic is reaching the appliance or leaving the appliance.
The appliance saves the captured packet activity to a file and stores the file locally.
You can configure the maximum packet capture file size, how long to run the
packet capture, and on which network interface to run the capture. You can also
use a filter to limit the number of packets seen by the packet capture which can
make the output more usable on networks with a high volume of traffic. You can
send any stored packet capture file using FTP to IronPort Customer Support for
debugging and troubleshooting purposes.
