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

physical ports can be aggregated into a common PAgP link
aggregate. Set the group 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.
CAUTION: For most versions of HP-UX, use lowercase
text when specifying on or off for HP_APA_HOT_STANDBY
in /etc/rc.config.d/hp_apaconf. Using uppercase
text might cause errors. This does not apply to HP APA
running on HP-UX 11i v2.
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, and for the May 2005 and later
releases of HP APA for HP-UX 11i v1 (B.11.11.20),
PHNE_33116 (B.11.11.17) patch release, and December
2005 and later releases of HP APA for HP-UX 11i v2
(B.11.23.10) 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 63).
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).
