RedHat Enterprise 6.4 Network Card Issue

Hi All,

I have a new Fujitsu Server which i have installed Red Hat Enterprise 6.4 command line only I have 2 onboard nic cards and a separate PCIe 4 channel nic card installed.

I need to configure the two onboard nic cards so that i can see two networks.  I plug in the cable for the two onboard nics and I get a up light on the nic and on the switch but i am unable to see the networks.  I have identified then as eth 4/5 and ensured issued the command:

"ifconfig eth4 up"
"ifconfig eth5 up"

Then rebooted the server but it wont see the network.

Also is it possible to change the name of eth4 to eth0 and eth5 to eth1 so that I can identify them easier in future.

I am pretty new to Red Hat so any advice would be great.

Yes, it is possible.

Issue these command

cd /etc/sysconfig/network-scripts
ls ifcfg*

You should see ifcfg-eth4 and ifcfg-eth5 files.

You should change the name of these files to ifcfg-eth0 and ifcfg-eth1 respectively.

Then open each file and:
1.  change DEVICE=eth4  or 5 to correct number
2.  Change ONBOOT option to yes.

Issue command
chkconfig network on

service network restart

This should do it
