*The tracing and logging of X.400-specific components can be done through x4admin, and is described in the Managing X.400—Administrator’s Guide. Tracing and logging of OTS and the link is still performed through nettl for X.400.

Tracing is only recommended if you have a good understanding of the protocol internals. When used, it is useful to trace at the layer your application uses and one level below.

For instance, to trace an FTAM application, you might enable tracing for the FTAM entities and ACSE/Presentation. To trace an XTI application, you might enable Transport and Network tracing. The kind of tracing will usually be PDU In, PDU Out, Header In, and Header Out.

To analyze the errors logged, see “Common Logged Errors” on page 67.
