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

• 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.
