Packet capture for unknown application traffic

You can generate packet capture information for unknown application traffic on your security device. You can use this information to get more insight on unknown applications. After you configure packet capture for the application traffic on your device, the packet capture function captures the packet details and stores the information in a packet capture (.pcap) file. You can use the packet capture details of an unknown application to define a new custom application signature and create a security policy rule to manage the application traffic more efficiently. You can submit the packet capture information to Juniper Networks to debug why an application is not detected, and if required, request to create an application signature.
