# Bond Ethernet Devices
<a name="config-cond-cf-cg-ethernet-bond"></a>

You can bond Ethernet devices to suit your networking requirements. For example, you might set up two Ethernet devices as an active/redundant pair. Or, if you have two Conductor nodes, you might bond the management interfaces on the two nodes.

**Topics**
+ [Step A: Create the Bond](#config-cond-cf-cg-ethernet-bond-create)
+ [Step B: Assign the Devices](#config-cond-cf-cg-ethernet-bond-assign)

**Important**  
We recommend that you set up both eth0 and eth1 with static IP addresses. Eth0, eth1 and bond0 should also all on the same subnet.

**Prerequisites**  
Before you begin this process, make sure that you've done the following:
+ [Added to AWS Elemental Conductor File the Ethernet devices](config-wrkr-cf-cg-ethernet-add.md) that you're bonding.

## Step A: Create the Bond
<a name="config-cond-cf-cg-ethernet-bond-create"></a>

1. Make sure that you have set up the two devices that you want to bond.

1. On the Conductor web interface, choose **Nodes** in the main menu.

1. On the **Nodes** screen, choose **Edit** (wrench icon) beside the primary Conductor node.

1. On the **Node Configuration** screen, choose **Network** >** Network Devices**.

1. On the **Network Devices** tab, choose **Add Network Device**.

1. In the **Add Network Dialog** dialog, select **bond** as the device type. The dialog immediately expands to include more fields.

1. Complete the fields as follows:  
****    
[See the AWS documentation website for more details](http://docs.aws.amazon.com/elemental-cf2/latest/configguide/config-cond-cf-cg-ethernet-bond.html)

1. Choose **Save**. The new device appears in the Network Devices list.

1. If you have a secondary Conductor node, switch to the web interface for that node and repeat these steps. 

## Step B: Assign the Devices
<a name="config-cond-cf-cg-ethernet-bond-assign"></a>

1. Revise the two regular Ethernet devices as follows:
   + **Management**: Always Unchecked. This indicates that whether the devices are management or not is defined in the bond, not in the individual devices.)
   + **Master Device**: Select the bond that you just created (for example, bond0).

1. Choose **Save**. The Network Devices list shows the two Ethernet devices and the bond, as displayed in this example:

1. If you have a secondary Conductor node, switch to the web interface for that node and repeat these steps.
