Take a Custom Application Packet Capture

Using a terminal emulation application, such as PuTTY, launch an SSH session to the firewall.

Turn on the application packet capture and define filters.

admin@PA-220>
set application dump on application 
<application-name> rule 
<rule-name>

For example, to capture packets for the facebook-base application that matches the security rule named rule1, run the following CLI command:

admin@PA-220>
set application dump on application facebook-base rule rule1

You can also apply other filters, such as source IP address and destination IP address.

View the output of the packet capture settings to ensure that the correct filters are applied. The output appears after enabling the packet capture.

In the following output, you see that application filtering is now on based on the facebook-base application for traffic that matches rule1.

Access Facebook.com from a web browser to generate Facebook traffic and then turn off application packet capture by running the following CLI command:

admin@PA-220>
set application dump off
