HP Auto Port Aggregation Administrator's Guide for HP-UX 11i v3 September 2008

capability to be the same for all network physical ports
in the same link aggregate. Ports going to different link
aggregates must have different group capabilities. This
value must match the value of
HP_APAPORT_GROUP_CAPABILITY in the /etc/
rc.config.d/hp_apaportconf file.
HP_APA_HOT_STANDBY
Configure a link aggregate for Hot Standby mode. This
parameter is mutually exclusive with the
HP_APA_LOAD_BALANCE_MODE parameter. In addition,
HP_APA_HOT_STANDBY takes precedence over the
HP_APA_LOAD_BALANCE_MODE parameter. The
permissible values are on and off. The default is off.
HP_APA_INTERFACE_NAME
Name of the link aggregate. For example, lan900 and
lan901.
HP_APA_KEY
For LACP_AUTO only. An integer value that determines
which network physical ports can be aggregated into a
common LACP link aggregate. Set the key to be the same
for all network physical ports in the same link aggregate.
Ports going to different link aggregates should have
different keys. Must match the value of HP_APAPORT_KEY
in the /etc/rc.config.d/hp_apaportconf file.
HP_APA_LACP_SYSTEM_ID_MODE
For 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.
HP_APA_LACP_TIMEOUT
For LACP_AUTO mode only. Specifies the length of the
LACP timeout. This is also a global parameter. For a
description of this parameter, see “Modifying HP APA
Global Parameters” (page 44).
HP_APA_LOAD_BALANCE_MODE
Defines the load-balancing mode for the specified link
aggregate (HP_APA_INTERFACE_NAME). The supported
values are as follows:
• LB_MAC
• LB_IP
• LB_PORT
For a description of these parameters, see the load
distribution algorithms in “Link Aggregate Advanced
Parameters” (page 34).
NOTE: Some IP applications might not have TCP/UDP
port numbers, or the TCP/UDP port numbers are
encrypted. For such cases, even if you choose LB_PORT,
it will fall back to the default LB_MAC.
HP_APA_MANUAL_LA
Manually set ports for the specified link aggregate. Specify
the ports with PPA numbers. Separate each port by a
comma (,).
HP_APA_MAX_LINKAGGS
Sets the maximum number of link aggregates for the server.
The valid range is from 5 to 50. The default value is 50.
This value takes effect only after a reboot.
HP_APA_USE_SYSLOG
Enables (1) or disables (0) the logging of status messages
to the syslog.log file (for example, when a link
