SCTP Event Types

A guide to SCTP event types and severity levels.
The firewall generates SCTP logs when the following events occur, and these events are displayed both in the logs and on the SCTP Events widget on the ACCMobile Network Activity. With the exception of the SCTP session start and SCTP session end logs, the firewall logs other SCTP events when you Configure SCTP Security. The session start and session end logs are generated when you enable logging in Security policy rules.
The event code for all SCTP event types is 0.
