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.
