# Sample xCAT post script for configuring eth1 based on eth0 settings and
# some conventions.
# This scripts works for both diskfull installs, diskless boots on AIX or Linux.
# To use, change the settings of the following variables at the top of this script:
# $nic_num - set this to the interface number, e.g. 1 for eth1 or en1
# $netmask - the netmask that should be used when ifconfig'ing this NIC
use strict;
