Example B-1 shows a sample /etc/lanmon/lanconfig.ascii ASCII configuration file.
This file contains configuration information that LAN Monitor uses
for failover groups. Example B-1 Sample lanconfig.ascii Configuration File |

#******* LAN MONITOR CONFIGURATION FILE
#*** For complete details about the parameters and how

#*** All timeout values are microseconds; they are rounded up

#***********************************************
# The valid range for POLLING_INTERVAL: 500,000-10,000,000 usec
# Default value for POLLING_INTERVAL: 10,000,000 usec
# Minimum value for DEAD_COUNT: 2
# Default value for DEAD_COUNT: 3
#**********************************************
POLLING_INTERVAL 10000000
DEAD_COUNT 3
#***********************************************
# By default, LM_RAPID_ARP is on.
# If LM_RAPID_ARP is on, the valid ranges are:
# LM_RAPID_ARP_INTERVAL: 1000000-4000000 (default:1000000 usec
# LM_RAPID_ARP_COUNT: 5 - 60 (default is 10)
# (LM_RAPID_ARP_INTERVAL * LM_RAPID_ARP_COUNT) <= 60s

LM_RAPID_ARP off
LM_RAPID_ARP_INTERVAL 1000000
LM_RAPID_ARP_COUNT 10

# Note: **
# **
# In Proactive Failover, the active port of a fail-over group **
# is the port with the minimum normalized port cost. This means **
# a fail-over group will change its active port to a ready port **
# having a lower normalized port cost, even when the current **
# active port remains up. You must use cost-based fail-over **
# groups in order to get the Proactive Failover behavior. **
# **
# To define a cost-based fail-over group, all the ports in the **
# fail-over group must have a cost defined. Cost has a valid **
# range of between 1 and 100, inclusive. The value must be **
# preceded by a colon (:) character. **
# **
# If one of the ports in a fail-over group does not have a cost **
# defined, the fail-over group is invalid. **
# **
# If all ports in a fail-over group have no cost defined, the **
# default failover behavior is used. The available port with **
# the highest priority becomes the active port. **
# **
# By default, the lanqueryconf -s command creates only **
# priority-based fail-over groups. **
# **
# Example with cost defined: **
# FAILOVER_GROUP lan903 **
# STATIONARY_IP 195.55.55.55 **
# # Pri/Stdby I/f Pri Cost **
# PRIMARY lan900 7 : 1 **
# STANDBY lan901 6 : 2 **

The lanconfig.ascii configuration file contains the following
fields: - NODE_NAME
The name of the system as obtained by gethostname()(). This must be the first line in the file. - FAILOVER_GROUP
The name for a single LAN Monitor failover group.
You must specify a name for each LAN Monitor failover group on the
system. If the group consists of multiple ports (multiple PPAs), the
name format is lan9XX, where XX is a decimal number starting
with 00 (for example, lan900). Each FAILOVER_GROUP can have the following keywords: - STATIONARY_IP
The IPv4 or IPv6 (December 2005 and
later releases of HP-APA for HP-UX 11i v2 (B.11.23.10)) address dedicated
to the failover group. This is a required field; you must set it for
each failover group before running lanapplyconf. - PRIMARY
Specifies the active port for the FAILOVER_GROUP. Each failover group must have one port. This port is typically assigned
the highest priority or lowest cost value so it will be the port that
initially carries traffic. The port must also have IP addresses configured.
After lanapplyconf creates the failover group,
the IP addresses on the port (if present) are moved to the failover
group. HP recommends that you always assign the port the highest priority
or the lowest cost in a failover group. - STANDBY
Specifies a standby port for the FAILOVER_GROUP. A standby port is a port that replaces the active port when the
active is incapable of carrying traffic. Specify this keyword only
if the failover group has more than one port. A failover group must
have one or more standby ports.
Both the PRIMARY and STANDBY keywords have the following fields: 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” 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”. - 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”. - 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”. - 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”. - 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”.
