11i v3 Releases
New Features in B.11.31.1303 Release
The revision string for APA has been aligned with the HP-UX 11i v3 Operating Environments Update
Release (March 2013).
• Enhanced APA troubleshooting
APA internal tracing has been enhanced to capture required and necessary traces that are
useful in debugging APA. These messages are logged in APA internal trace buffer. These
traces can analyzed by HP Support using an HP internal tool (lanshow).
With this enhancement you can trace all the syslog.log messages and messages in the internal
trace buffer of APA , irrespective of HP_APA_USE_SYSLOG is enabled or not.
The parameter HP_APA_USE_SYSLOG in file /etc/rc.config.d/hp_apaconf when
enabled, selectively logs messages in syslog.log file. This parameter is disabled by default.

NOTE: MANUAL mode link aggregation has been deprecated. It is planned for future
obsolescence. HP recommends to not use this configuration. Configuration with link aggregation
in LACP mode is recommended.
NOTE: LB_PORT provides a better traffic distribution across each of the physical ports in the
aggregation. HP recommends using LB_PORT for efficient traffic distribution.
NOTE: HOT_STANDBY is obsoleted in this version. HP recommends using LAN_MONITOR.
