6.1 Trace information—for
advanced users
Trace outputs may be used to monitor the internal processes in the router
during or after configuration. One such trace can be used to display the indi-
vidual steps involved in negotiating the PPP. Experienced users may inter-
pret these outputs to trace any errors occurring in the establishment of a
connection. A particular advantage of this is: The errors being tracked may
stem from the configuration of your own router or that of the remote site.
Note: The trace outputs are slightly delayed after the actual event, but are
always in the correct sequence. This will not usually hamper interpretation
of the displays but should be taken into consideration if making precise
analyses.
6.1.1 How to start a trace
Trace output can be started in a Telnet session. Set up a Telnet connection
to your device. The command to call up a trace follows this syntax:
trace [code] [parameters]
The trace command, the code, the parameters and the combination com-
mands are all separated from each other by spaces.
