View Full Version : [ubuntu] Dell PowerEdge R310 Integrated NIC

February 1st, 2012, 04:33 PM
Hi Everyone,

I just have installed a Dell PowerEdge R310 with a fresh 11.10 installation. It has 2 Ethernet jacks for integrated NICs. We have set the server to have a fixed IP address, but the other Ethernet card is getting another IP from the DHCP server.

How do I have the two ports share the fixed IP and the traffic load?

If you want to have one IP address with two NICs, you will probably have to 'bond' the NICs together:


Quote from the site about what 'bonding' is:

Bonding is also called port trunking or link aggregation and it will let you combine several network ports to make a single group. This combines the the bandwidth from several interfaces as a single connection.

Hope this helps.

Thanks ruffEdgz,
I think that is exactly what I am looking for. I have installed the ifenslave package, but still have not been able to configure it correctly in /etc/network/interfaces

I have 2 interfaces that I want to share one IP address. They are eth0 and eth1. Does anyone have know how to set this up for these two interfaces to share one static IP?

OK i used the following codes and i accomplished the 2 ethernet ports sharing one IP from the man page for ifenslave -> http://manpages.ubuntu.com/manpages/oneiric/man8/ifenslave-2.6.8.html.

modprobe bonding
ifconfig bond0 netmask
ifenslave bond0 eth0 eth1
