GTP Cause Values in Logs

When you enable logging, GTP-C request and response messages include Information Element (IE) values that indicates whether a message has been accepted or not, and when a message is rejected it provides a reason for rejecting the message.
GTPv1 rejection causes are numbered 64 to 127 and GTPv2 are numbered 192 to 240. The following table lists the GTP causes that are printed in logs. For causes that are not listed in the table, only a cause code is displayed.
