Ethernet port not detected

Question

Ethernet port not detected

I just added additional 1gb port to my existing 4gbs on my server. All 4 are placed on a NET CARD PCIE 1GB E1G44HTBLK 904223 INTEL and the additional one is connected to motherboard(S5520SC) integrated Ethernet port.

from dmidecode I can see the motherboard ports are enabled. but I cannot see the connected port with ifconfig, and nothig in /var/log/messages

If this file exists, /etc/udev/rules.d/70-persistent-net.rules then remove it. Now create your own /etc/sysconfig/network-scripts/ifcfg-eth6 file. Also make sure that, all the network addresses updated promptly in the respective config files.

Else, you can append your new network device details in this file, /etc/udev/rules.d/70-persistent-net.rules

SUBSYSTEM=="net", ACTION=="add", DRIVERS=="?*", ATTR{address}=="xx:xx:xx:xx:xx:xx", ATTR{type}=="1", KERNEL=="eth*", NAME="eth5"

Are you sure you are not configured bonding? From the above, it seems that you are with bonding enabled. If bonding enabled for interfaces, it wont show any ip's.
