Monitor GTP traffic passing through a Palo Alto Networks
firewall by viewing Mobile Network Activity on the ACC and by running
predefined and custom reports.
When you enable logging in a Security policy rule, the
firewall generates a traffic log when traffic matches the criteria
defined in the policy rule, and GTP logs for GTP session start and
GTP session end for each mobile subscriber. All other logs for GTP
traffic are event-based logs that are generated based on the options
you enable on the GTP
Protection Profile. For monitoring GTP traffic, the firewall
uses the GTP logs to render a visual display on the Mobile Network
Activity tab on the ACC, and gives you both predefined reports and
the ability to generate custom reports.
