LAN Monitor Trace

Each of the local area network data link controls (DLCETHER, DLC8023, DLCFDDI, and DLCTOKEN) provides an internal monitor trace capability that can be used to identify the execution sequence of pertinent entry points within the code.

This is useful if the network is having problems that indicate the data link is not operating properly, and the sequence of events may indicate the cause of the problems. This trace is shared among the LAN data link controls, and inactive is the default.

The LAN monitor trace can be enabled by issuing the following command:

trace -j 246

where 246 is the hook ID to be traced.

Tracing can be stopped with the trcstop command and a report can be obtained with the following command:

trcrpt -d 246

where 246 is the hook ID of the trace for which you want a report.

Note: Exercise caution when enabling the monitor trace, since it directly affects the performance of the DLCs and their associates.

For information on additional ways to use trace facilities, see DLC device driver management in AIX® Version 7.1 Networks and communication management.
