HP UX Auto Port Aggregation (APA) Software manual Lanconfig File

	• The LAN interface name (for example, lan0 and lan1).
	• The port priority that will be assigned to the port. The port
	with the highest priority is the port.
	• A cost value for the LAN interface preceded by a colon (:).
	This is an optional field. See “Proactive Failover” (p. 15)
	for more information.
POLLING_INTERVAL	The number of microseconds between polling messages. You
	can specify this keyword multiple times in the configuration
	file. A link aggregate's polling interval is set to the last specified
	interval. For a description of this parameter, see “Failover
	Group Advanced Parameters” (page 35).
DEAD_COUNT	The number of polling packets that are missed before LAN
	Monitor sends a nettl log message to the user that indicates
	the link might have problems and the network should be
	checked. For a description of this parameter, see “Failover
	Group Advanced Parameters” (page 35).
LM_RAPID_ARP	Enables (on) or disables (off) the ability to transmit gratuitous
	ARP messages at intervals shorter than 5 seconds. By default,
	LM_RAPID_ARP is off. For a description of this parameter, see
	“Failover Group Advanced Parameters” (page 35).
LM_RAPID_ARP_INTERVAL	The number of microseconds between rapid gratuitous ARP
	messages. If the value is out of the valid range and
	LM_RAPID_ARP is on, the interval value last processed with
	the lanapplyconf command is used. If LM_RAPID_ARP is
	off, this value is ignored for the corresponding failover group.
	For a description of this parameter, see “Failover Group
	Advanced Parameters” (page 35).
LM_RAPID_ARP_COUNT	The number of gratuitous ARP packets sent rapidly. If the value
	is not in the valid range and LM_RAPID_ARP is on, the count
	value last processed with the lanapplyconf is used. If
	LM_RAPID_ARP is off, this value is ignored for the
	corresponding failover group. For a description of this
	parameter, see “Failover Group Advanced Parameters”
	(page 35).

If you specify the POLLING_INTERVAL, DEAD_COUNT, LM_RAPID_ARP_INTERVAL, and

LM_RAPID_ARP_COUNT fields once in the lanconfig.ascii file before all failover, the values apply to all failover groups. If you specify them multiple times in the file, the values apply only to those failover groups that follow these fields; you can set different values for failover groups.

lanconfig File

The /etc/lanmon/lanconfig file is a binary file that stores the current snapshot of the aggregates. Because you cannot modify the aggregates using the lanadmin command, and you cannot edit this file. It correctly represents the current configuration.

CAUTION: Do not edit the binary file because you can corrupt the data. Do not change the name or directory location. Doing so can make the product malfunction.
