Managing Network Interfaces

After your instance has been built, you might find a need to add additional interfaces or change your existing one.  Managing your interface easy.  First, of course, you need have additional networks from which to choose.

For more information about creating virtual networks, go HERE .

If you have at least two networks, you can add a second interface and connect to the second network by going to the instance's details page, selecting the "Networks" tab and clicking on "Add Network"  This will bring up a new dialog box from which you can select the second network by clicking on the down arrow.  Double-click on your choice.  

You can either allow the system to assign an address from the pool or assign one yourself. Click on the "Add Network" button to complete the process.

Once committed, a message will appear at the top of your portal and the new network connection will appear in your browse window as shown below.

You will notice that the first network is still marked as the default network for this instance.  All subsequent networks will be flagged as "No".  There can only be one default network.  Changing the default is just as easy as it is to create new interfaces.  Click on the "Change Default Network" button in your browse window.  This will bring up a new dialog box from which you can select which network will become the default.  Click on the "Update Default Network" button to complete the process.

A banner indicating that you are changing your default network will appear at the top of your portal and the order of the networks in the browse window will change as seen below.

Should you need to remove a network interface, all you need to do is click on the Terminatebutton following the target network to be deleted. A dialog box will appear near the top of the screen which will require you to confirm the deletion.  Click "OK" to complete the process.

Only networks that are not the default network can be deleted

When you add a new network after the instance has been created, you may need to go into your instance and reconfigure networking at the OS level.  Adding another network may not automatically update your virtual machine.
