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

5 Administering HP APA
Administering HP APA consists of performing the following tasks:
• “Modifying HP APA Global Parameters” (page 63)
• “Logging Messages to the syslog.log File” (page 63)
Modifying HP APA Global Parameters
The following HP APA global parameters are stored in the /etc/rc.config.d/hp_apaconf
file:
Default Port Mode The default configuration mode for link aggregates. The supported
values are as follows:
MANUAL Disables FEC and IEEE 802.3ad LACP on all
ports that support HP APA. You must manually
add or remove them from the specific link
aggregate. This is the default.
FEC_AUTO Starts FEC on all ports that support HP APA.
LACP_AUTO Starts IEEE 802.3ad LACP on all ports that
support HP APA.
LAN_MONITOR Disables FEC and IEEE 802.3ad LACP on all
ports that support HP APA. The ports will be
used for a failover group.
MAX Link Aggregates Sets the maximum number of link aggregates for the server. The
valid range is from 5 to 50, inclusive. The default value is 50. This
value takes effect only after a reboot.
LACP SYSID Mode LACP_AUTO only. Directs APA how to set up the LACP System
ID. The supported values are as follows:
FIRST_APA_PORT
Sets the LACP System ID to the first
supported HP APA port. This is the
default.
FIRST_LACP_PORT
Sets the LACP System ID to the first
active (UP) port that starts LACP.
LACP Timeout For the September 2007 release of HP APA for HP-UX 11i v1 and
v2 this specifies an interval of time between LACP Protocol Data
Units (PDUs) after which the server considers the LACP link
partner to be down. The supported values are as follows:
0 Specifies a slow timeout. This is approximately 30 seconds.
This is the default.
1 Specifies a fast timeout. This is approximately 3 seconds.
Use Syslog Enables (1) or disables (0) the logging of status messages to the
syslog.log file (for example, when a link aggregate or port fails
or comes up). The default value is 0. See Section (page 63) for
sample syslog.log messages and their meaning.
To change a global parameter, edit the /etc/rc.config.d/hp_apaconf and make the
necessary changes. For more information, see “hp_apaconf File” (page 97).
Logging Messages to the syslog.log File
For the May 2005 release of HP APA for HP-UX 11i v1 (B.11.11.20) and later, the PHNE_33116
(B.11.11.17) release, and the December 2005 release for HP-UX 11i v2 (B.11.23.10), you can enable
the logging of APA and LAN Monitor status messages to the syslog.log file. The status
