Support Commands
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.
The Support and Help > Packet Capture page displays the list of complete packet capture files stored on 
the hard drive. When a packet capture is running, the web interface shows the status of the capture in 
progress by showing the current statistics, such as file size and time elapsed.
You can download the packet capture files using the Download button in the web interface, or by 
connecting to the appliance using FTP and retrieving them from the captures directory.
In the CLI, use the 
packetcapture
 command.
In the web interface, select the Packet Capture option under the Support and Help menu.
Note
The packet capture feature is similar to the Unix tcpdump command.
Starting a Packet Capture
To start a packet capture in the CLI, run the 
packetcapture > start
 command. If you need to stop a 
running packet capture, run the 
packetcapture > stop
 command.
To start a packet capture in the web interface, select the Packet Capture option under the Support and 
Help menu, and then click Start Capture. To stop a running capture, click Stop Capture.
Note
The web interface only displays packet captures started in the web interface, not from the CLI. Similarly, 
the CLI only displays the status of a current packet capture run started in the CLI.
Editing Packet Capture Settings
To edit the packet capture settings in the CLI, run the 
packetcapture > setup
 command.
To edit packet capture settings in the web interface, select the Packet Capture option under the Support 
and Help menu, and then click Edit Settings.
