The nettl command captures network
events and packets. The logging portion captures state changes, errors,
and connection establishment. The tracing portion capture inbound
and outbound packets going through the network and loopback and header
information. Log messages are written to the /var/adm/nettl.LOG000 file. To format and view the contents of this file, enter the following
command:
# netfmt -v -f /var/adm/nettl.LOG000 | more |
Look for Error and Disaster messages.
APA also supports the logging of status messages
to the syslog.log file. See “Logging Messages to the syslog.log File” for information
on enabling this feature.
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 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--------------@#%
Timestamp : Wed Aug 18 PDT 2004 09:37:56.600031
Process ID : [ICS] Subsystem : HP_APA

Connection ID : 0 Log Instance : 0
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
<3014> HP Auto-Port Aggregation product disabled TCP Segmentation Offload
capability for link aggregation 903.
|
When the TSO capability is enabled on an aggregate,
an INFORMATIVE message similar to the following is logged:
----------------------Auto-Port Aggregation/9000 Networking--------------@#%
Timestamp : Wed Aug 18 PDT 2004 09:37:53.020072
Process ID : [ICS] Subsystem : HP_APA

interface and the GUI version, see nettl(1M) and nettladm(1M), respectively. See netfmt(1M) for information on creating
a filter for trace formatting.
