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 Cisco IronPort Customer Support for debugging and
troubleshooting purposes.
