Subsequent chapters in this guide describe the configuration commands. User/privilege mode
commands that are also configuration commands (for example, ‘show’) are described in more detail
in the related configuration command chapter.
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.
interface
U/P Dials or disconnects an interface.
no packet-trace
U/P Turns off packet tracing.
nslookup
U/P Resolves an IP address to a host name and vice-versa.
packet-trace
U/P Performs a packet trace.
ping
U/P Pings an IP address or host name.
ping6
U/P Pings an IPv6 address or a host name.
psm
U/P Goes to psm (product support module) mode for setting product parameters. You may need to
use the htm commands if your customer support Engineer asks you to during troubleshooting.
Note: These commands are for ZyXEL’s internal manufacturing process.
