You can use the DISPLAY CSDUMP command to display the current dump triggers set by the MODIFY CSDUMP command or by the CSDUMP start option. The display shows the current CSDUMP message and sense code triggers that will initiate a dump. If either the message or the sense code trigger does not exist, then NONE is indicated.

See the DISPLAY CSDUMP and MODIFY CSDUMP commands in z/OS Communications Server: SNA Operation for more information.
