Debugging PIM-SM
When PIM-SM runs abnormally, you can run the commands described in this section in the user view to debug PIM, then view the debugging information and locate the fault.
Before enabling the debugging, you must run the terminal monitor command and the terminal debugging command in the user view to enable the information display and debugging display functions of the terminal, so that debugging information is displayed on the terminal.
Enable the debugging affects the system performance. When the debugging is complete, run the undo debugging all command immediately to disable the debugging.
