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:
