  Working With Support
Step 3
Complete the Customer Support Remote Access options:
Step 4
Submit and commit your changes. 
Step 5
Look for the seed string in the Success message near the top of the page and make a note of it. 
For security reasons, this string is not stored on the appliance and there is no way to locate this string 
later. 
Keep this seed string in a safe place. 
Step 6
Give the seed string to your Support representative. 
Packet Capture
The appliance provides the ability to capture and display TCP/IP and other packets being transmitted or 
received over the network to which the appliance is attached.
Note
The packet capture feature is similar to the Unix tcpdump command.
Starting a Packet Capture
Step 1
Choose Support and Help > Packet Capture.
Option
Description
Seed String 
If you enter a string, the string should not match any existing or future 
password. 
The string will appear near the top of the page after you click Submit. 
You will give this string to your support representative. 
Secure Tunnel 
(recommended)
Specifies whether or not to use a secure tunnel for remote access 
connections. 
When enabled, the appliance creates an SSH tunnel over the specified port 
to the server upgrades.ironport.com, over port 443 (by default). Once a 
connection is made, Cisco Customer Support is able to use the SSH tunnel 
to obtain access to the appliance. 
Once the techsupport tunnel is enabled, it will remain connected to 
upgrades.ironport.com
 for 7 days. After 7 days, no new connections can 
be made using the techsupport tunnel, though any existing connections will 
continue to exist and work. 
The Remote Access account will remain active until specifically deactivated.
