Instead of using setup command you can manually configure your NIC.
You can see configuration of your first NIC (eth0) in the following file
Code:
/etc/sysconfig/network-scripts/ifcfg-eth0
Use it as a sample and edit or create another file for your second NIC (eth1) i.e
Code:
/etc/sysconfig/network-scripts/ifcfg-eth1
.
after that you need to restart your network service
Code:
service network restart
