HP Auto Port Aggregation Administrator's Guide for HP-UX 11i v1 and 11i v2 September 2008

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
Whenever the TSO status of a link aggregate or failover group changes, a warning message is
logged in the nettl.LOG000 file. For example, when the TSO capability is disabled on an
aggregate, a WARNING message similar to the following is logged:
----------------------Auto-Port Aggregation/9000 Networking--------------@#%
