Turning all possible debugging on is extremely CPU intensive, and will probably cause your router to crash. Use extreme caution if you try this on a production device. Instead, be selective in which debug commands you turn on.
Do not leave debugging turned on. After you have gathered the necessary information from debugging, turn all debugging off. If you wish to turn off only one specific debug command and leave others on, issue the no debug x command, where x is the specific debug command you want to disable.
