HP Auto Port Aggregation Administrator's Guide HP-UX 11i v3 (766140-001, March 2014)

You can access the logging and tracing utility using either the graphical user interface (GUI) version
or the command line interface. The GUI version does the following:
• Guides you through logging and tracing tasks.
• Enables you to create and format reports.
• Collects logging and tracing information specific to a subsystem.
• Displays report screens that are updated instantaneously with current logging and tracing
information by the subsystem.
• Provides context-sensitive on-line help.
To access the GUI version of the logging and tracing utility, enter the following command:
nettladm
There are three levels of logging:
• At link aggregate level
• At Cisco's FEC level
• At IEEE 802.3ad LACP level
The following examples show how to perform different tasks from the command line:
• To turn on all logging at link aggregate level, enter:
nettl -log 0xf -e HP_APA
• To turn on all logging at Cisco's FEC level, enter:
nettl -log 0xf -e HP_APAPORT
• To turn on all logging at IEEE 802.3ad level, enter:
nettl -log 0xf -e HP_APALACP
• To examine the log file with cause and action descriptions, enter:
netfmt -v -f /var/adm/nettl.LOG00 | more
• To examine just the log messages in the log file, enter:
netfmt -f /var/adm/nettl.LOG00
• To check network logging and tracing status, enter:
nettl -status
• To start Cisco's FEC tracing to the file /tmp/tracefile.TRC0, enter:
nettl -traceon all -entity HP_APAPORT -file /tmp/tracefile
• To stop Cisco's FEC tracing, enter:
nettl -traceoff all -entity HP_APAPORT
• To start LACP tracing to the file /tmp/tracefile.TRC0, enter:
nettl -traceon all -entity HP_APALACP -file /tmp/tracefile
• To stop LACP tracing, enter:
nettl -traceoff all -entity HP_APALACP
• To format the tracefile into the file /tmp/traceout, enter:
nettl -f /tmp/tracefile.TRC0 > /tmp/traceout
