HP UX Auto Port Aggregation (APA) Software manual Administering HP APA

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
