Configuring An Ibm Aix Server; Configuring A Virtual Ip Address On A Novell Netware 6 Server - Alcatel-Lucent OmniSwitch 6850-48 Network Configuration Manual

Configuring Server Load Balancing

Configuring an IBM AIX Server

Follow the steps below to configure the loopback interface on an IBM AIX server.
1
At the command prompt, enter ifconfig lo0 alias, the Virtual IP (VIP) address of the Server Load
Balancing (SLB) cluster, netmask, and the net mask for the VIP. For example, to configure the loopback
address on a IBM AIX server with a VIP of 10.123.11.14 with a net mask of 255.0.0.0 enter:
ifconfig lo0 alias 10.123.11.14 netmask 255.0.0.0
2
Create a file called "/etc/hostname.lo0:1" file with the user-configured name for the loopback inter-
face. In this example we will use "loopbackVIP".
3
Create a line in the /etc/hosts file with the VIP you configured in Step 1, a space, and the name you
configured in Step 2. For example, if the VIP address is 10.123.11.14 and the name you configured in the
/etc/hostname.lo0:1 file is "loopbackVIP", add the following line to the /etc/hosts file:
10.123.11.14 loopbackVIP

Configuring a Virtual IP Address on a Novell Netware 6 Server

Follow the steps below to configure the VIP (i.e., secondary) address on a Novell Netware 6 server.
Note. For other versions of Netware, please refer to your server documentation.
1
At the server prompt enter add secondary ipaddress followed by the VIP address and noarp. For
example, to configure a VIP address of 10.123.11.14 enter:
add secondary IPAddress 10.123.11.14 noarp
Note. As an option you can enter prompt (which allows you to select from available interfaces) after the
noarp keyword. If you do not use the prompt keyword then the VIP will be added to the first bound inter-
face of the same network.
2
As an option you can enter display secondary ipaddress at the server prompt to verify your VIP
address.
Note. If you wish to delete a VIP address enter del secondary ipaddress followed by the VIP address.
