Changing the default startup to permit 4.3 BSD ASCII configuration

You can administer network interfaces for AIX® through the SMIT and ODM files, or through 4.3 BSD ASCII configuration files.

To administer network interfaces through 4.3 BSD ASCII configuration files, uncomment the commands in the /etc/rc.net file below the heading:
# Part II - Traditional
Configuration

Then if you want flat file configuration and SRC support, edit the /etc/rc.net file and uncomment the hostname, ifconfig, and route commands with the appropriate parameters.

If you want flat file configuration without SRC support, use the smit setbootup_option fast path to change the system to BSD-style rc configuration. This option configures the system to use the /etc/rc.bsdnet file at startup. You also have to edit the /etc/rc.bsdnet file and uncomment the hostname, ifconfig, and route commands with the appropriate parameters.
