NMDUMP allows you to modify formatting options for specified subsystem IDs.
There are three ways to change the formatting menu options.
Most options toggle between two possible values, like YES
or NO and ON or OFF. Some require you to enter an option number which then displays an
additional menu and prompt. Several options prompt you to enter the numbers of certain
items.
The following tables show the options for logging and tracing. Some logging and
tracing options also have filters you can specify.
You may type // at any of the main NMDUMP prompts to exit the
program. If NMDUMP is displaying a subsystem menu, you must press
[RETURN] to exit the menu and return to the main NMDUMP prompt before
typing // to exit the program.
You may also type "Help" at any of the main NMDUMP prompts for help
text.

Link Subsystem Formatting
The link manager subsystem does not call any menus. NMDUMP formats
logging messages only. The first line
labels the error as a link manager error, and shows whether it is
fatal or non-fatal. The next line contains the time and date of
the event. This line is followed by the log message, the requestor
ID, the link name, and the logical device (LDEV) of the link.
The requestor ID is for internal use only. Any underlying errors are reported
below the LDEV field. Many messages correspond to NMERR messages that are
documented in Appendix A "NMS Error Messages" of
this manual.
