218 ATMOS Console Commands Reference Manual (Binary) DO-008530-PS, Draft B (26th April 2001)
12.46 trace
12.46.1Syntax
trace [<option>]
12.46.2Description
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 179). 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 172). 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.
• ip . This turns on tracing for all interfaces.
• all . 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 hidden , not shown by ip help . It is useful mainly
for debugging and troubleshooting.
