Logging and Tracing Messages
HP-UX LAN comes with an online message catalog that reports LAN problems, probable
causes, and actions for you to take to correct the problems. Messages are sent either to the
system console or log files based on the logging and tracing configuration. To view the
probable cause and action text of the message, use the netfmt command with the -v option.
Below is an example.
# netfmt -v -f /var/adm/nettl.LOG00

Check the LAN cable to make sure its properly connected to the
LAN card.Use the lanscan (1M) command to find the NMID of the
LAN card and reset this card. If the reset does not solve the
problem, reboot.
If rebooting is ineffective, notify your HP representative.
HP-UX LAN uses the nettl logging and tracing facility supplied with HP-UX to capture,
control, and format messages produced by LAN. See the nettl(1M) man page for information
on using the graphical user interface or command line interface. The graphical interface,
which is accessed by running the nettladm command, includes the following features:
• screens which take you through any logging or tracing task desired
• screens which allow you to create and format reports
• the capability of logging and tracing subsystem-specific information
• main screens which are updated instantaneously with current logging and tracing
information by subsystem
• context-sensitive on-line help
