7. Compare the /etc/lanmon/lanconfig.ascii file with the /tmp/filename file.
If they are not the same, decide which file you want to use. If you want to use the file in
/tmp, copy that file to /etc/lanmon/lanconfig.ascii.
8. Edit the /etc/lanmon/lanconfig.ascii file and change the number of ports in the
failover groups, the dead count, poll interval, rapid ARP setting, rapid ARP interval, rapid
ARP count, and stationary IP address. The following example shows a failover group entry
that contains an IPv6 address:
FAILOVER_GROUP
9. Verify that the configuration in /etc/lanmon/lanconfig.ascii is still valid by using
the lancheckconf command.
10. Create the failover groups specified in the configuration file by using the lanapplyconf
command.
This command creates the specified failover groups.
Check the failover groups by using the nwmgr -S apa and netstat -in commands.
NOTE:
command.
11. The failover group is now operational. A reboot will restart the failover group as long as
the /etc/lanmon/lanconfig.ascii file is intact.

Example: Configuring a failover group

Suppose you want to configure a simple, two-port LAN Monitor failover group on a K-class
system. You enter the netstat and ioscan commands as follows:
# netstat -in
Name Mtu Network
lan1 1500 192.1.1.0
lan0 1500 191.1.1.0
lo0 4136 127.0.0.0
# ioscan -fkC lan
Class I
========================================================================
lan 1
lan 2
lan 3
lan 4
lan 0
#
The netstat output shows that lan1 is currently configured with IP address 192.1.1.153. The
ioscan output shows spare 1000Base-T devices lan2, lan3, and lan4.
You decide that lan2 will be the standby link for the failover group, with lan1 as the active
device.
To configure the failover group, do the following:
100 Configuring HP APA by editing files
STATIONARY_IP 192.1.1.1
STANDBY lan11
PRIMARY lan10
STATIONARY_IP
STANDBY
PRIMARY
If you later want to delete all the failover groups created, enter the landeleteconf
