Cisco Cisco Web Security Appliance S380 Guida Utente

techsupport tunnel will have closed after 7 days. The timeout set on the SSH 
tunnel connection does not apply to the Remote Access account; it will remain 
active until specifically deactivated.

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.
