10.50 trace
10.50.1Syntax
trace [<option>]
10.50.2Description
Turns on an IP tracing option, or lists the available options. Note that tracing
messages are written to background output, so with the standard console one must
use the
event commands to see them.
An option can be:
• One of various keywords. The details of just what tracing messages are enabled by
each keyword are not documented here; examine the source code for more
information.
• An association number (see the command files on page 170). For a TCP association
this turns on detailed tracing of events (including all packet transmission and
reception) on that association; for a UDP association it has no effect. The
files
command shows (by appending TRACE) whether each association has tracing
enabled.
• An interface name (see the command device on page 162). This turns on tracing of
every packet sent or received through the interface (one line per packet). The
device command shows (by appending TRACE) whether each interface has
tracing enabled.
• i p. This turns on tracing for all interfaces.
• al l. This turns on all tracing.
Note – trace does not display which associations and interfaces are being
traced; one must use the files and device commands for that.
The trace command is hidde n, not shown by ip hel p. It is useful mainly for
debugging and troubleshooting.
