2.1.1 Debug Commands

Debug commands marked with an asterisk (*) are not available when the debug flag is on and are
for ZyXEL service personnel use only. The debug commands follow a Linux-based syntax, so if there
is a Linux equivalent, it is displayed in this chapter for your reference. You must know a command
listed here well before you use it. Otherwise, it may cause undesired results.
