HP UX Auto Port Aggregation (APA) Software manual To stop Ciscos FEC tracing, enter

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:
