4. On the Delete Provider Network screen, click Yes, delete.
5. Verify the network deletion by reviewing the fields on the Provider Networks screen.
About Private Networks
Private Networks are created from a pool of VLANs, which you configure using the CloudSystem
Console. The OpenStack Networking service assigns VLANs from this pool to Private Networks
when they are created by end users using the CloudSystem Portal.
End users create Private Networks to associate with their provisioned virtual machine instances.
End users can assign Private Networks to virtual machine instances during virtual machine
provisioning.
Private Networks in the cloud
Private Networks are part of the Cloud Data Trunk. End users create individual Private Networks
using VLANs that you identify for that purpose. Therefore, each Private Network is shared exclusively
among members of a given project. See also How it works (page 15).
Managing private networks
Using the CloudSystem Console, you can select which VLANs are available for provisioning to
private networks. Once you add a private network VLAN, you can also use the console to delete
VLAN IDs, removing them from the pool of VLANs available for private network assignment.
End users use the CloudSystem Portal to create new private networks mapped to available VLANs,
and to manage their private network topologies. When a user configures a private network in the
CloudSystem Portal, the OpenStack Networking service assigns a VLAN ID from the VLAN IDs
configured for that project. The user does not explicitly specify the VLAN ID for a private network.
You can also use the Dashboard to track the number of private network IP addresses that are
assigned to instances. See the Network section in Interpreting the Dashboard data.
Understanding private networks data
Select at least one VLAN to display data on the overview screen. When you select more than one
VLAN, your selections are highlighted in the list, the total number of networks selected is displayed
at the top of the overview screen, and detailed data for each network is displayed underneath.
The Dashboard also displays data about private networks. See the Network section in Interpreting
the Dashboard data.
Add VLAN IDs
Use this procedure to add VLAN IDs to the pool of VLANs available for Private Network assignments.
End users can then use the CloudSystem Portal to create Private Networks from these assignable
VLAN IDs.
Prerequisites
• Minimum required privileges: Infrastructure Administrator
• A pool of VLANs is created in the cloud and the VLANs are not yet allocated.
Procedure 30 Adding VLAN IDs for use in Private Networks
1. From the main menu, select Private Networks.
2. Click +Add VLAN.
3. List the VLAN IDs or VLAN ID ranges separated by commas in the box provided.
4. Click Add.
5. Verify that the new VLAN IDs are listed on the Private Networks overview screen.
