GTP Event Types and Severity

GTP events have categorized by their severity; the firewall generates GTP logs when GTP events occur.

The firewall generates GTP logs when the following events occur, and these events are displayed both in the logs and on the GTP Events widget on the ACCMobile Network Activity. With the exception of the GTP session start and GTP session end logs, GTP logs are triggered by the GTP protection profile configuration. The session start and session end logs are generated when you enable logging in Security policy rules.
