B HP APA configuration files
HP APA uses the following configuration files:
• /etc/rc.config.d/hp_apaconf
• /etc/rc.config.d/hp_apaportconf
• /etc/lanmon/lanconfig.ascii
The following sections describe each file and its parameters. For configuration examples that
describe editing these files, see Appendix C (page 85).
hp_apaconf file
The /etc/rc.config.d/hp_apaconf file contains the following general HP APA configuration
parameters for link aggregates. You must set each of the supported parameters on a specific link
aggregate prior to aggregating any physical ports. All of the link aggregate configuration
parameters begin with the prefix HP_APA_.
HP_APA_DEFAULT_PORT_MODE The default way to configure link aggregates is through
MANUAL port configuration mode. Ensure that switch ports
and server ports are set to the same trunking mode
(MANUAL or AUTO), duplex mode, and speed. Disable
FEC or LACP on any switch ports not intended to be used
with APA. There are two variables governing the mode of
ports:
• HP_APA_DEFAULT_PORT_MODE in the /etc/
rc.config.d/hp_apaconf file. Sets the default APA
configuration mode for all ports. The recommended
mode is MANUAL. The APA product is shipped with
the entry in the hp_apaconf file set to:
HP_APA_DEFAULT_PORT_MODE=MANUAL.
• HP_APAPORT_CONFIG_MODE in the /etc/
rc.config.d/hp_apaportconf file. Sets the APA
configuration mode for a single port. This variable takes
precedence.
A port's mode is set to the value of
HP_APA_DEFAULT_PORT_MODE, unless you specify its
mode using the HP_APAPORT_CONFIG_MODE variable.
Example 1:
If the configuration mode of a port is not set with
HP_APAPORT_CONFIG_MODE and
HP_APA_DEFAULT_PORT_MODE is not set, the port's
configuration mode is MANUAL.
Example 2:
If the configuration mode of a port is not set with
HP_APAPORT_CONFIG_MODE and
HP_APA_DEFAULT_PORT_MODE is set to MANUAL, the
port's configuration mode is MANUAL.
Example 3:
If the configuration mode of a port is set to LACP_AUTO
with HP_APAPORT_CONFIG_MODE and
HP_APA_DEFAULT_PORT_MODE is set to MANUAL, the
port's configuration mode is LACP_AUTO.
HP_APA_FIXED_MAC Enables (on) or disables (off) Fixed MAC mode on a link
aggregate.
