Delete Private Network VLAN
Use this procedure to delete unassigned Private Network VLANs. After you delete a VLAN, it cannot
be assigned to a Private Network.
Prerequisites
• Minimum required privileges: Infrastructure Administrator
• The VLAN status must be unassigned.
Procedure 31 Deleting a Private Network VLAN
1. From the main menu, select Private Networks.
2. Select one or more unassigned VLANs to be deleted.
3. Select Actions→Delete.
4. On the Delete VLANs screen, click Yes, delete.
5. With the filter set to All assignments, verify that the private network VLAN no longer appears
on the Private Network overview screen.
About the External Network
The External Network allows you to route virtual machine instances on Private networks out from
the CloudSystem private cloud to the data center, the corporate intranet, and the internet.
One External Network is automatically created during CloudSystem Foundation installation. Virtual
machines are not directly attached to the External Network. Internal Provider and Private networks
connect directly to virtual machine instances. The External Network connects to network nodes.
After installation, you can use the features in the CloudSystem Portal to enable use of the External
Network for accessing VM instances on cloud networks. You create a subnet for the External
Network. Cloud users can then create routers to connect the External Network to Private networks
for their projects. Traffic from the External Network is routed to selected virtual machines inside
the cloud using floating IP addresses.
Because a single subnet is allowed for the External Network, you should configure one that is large
enough to accommodate future expansion.
Configuring the External Network
To configure the External Network for use in routing traffic to selected virtual machines inside the
cloud, complete the following procedures:
1. Creating the External Network subnet (page 78)
2. Creating a router to connect Private Network instances to the External Network subnet (page 79)
3. Assigning floating IP addresses to instances (page 79)
Creating the External Network subnet
Creating an External Network subnet enables the network nodes to route traffic from the subnet
so that cloud users can access virtual machine instances on Private networks. Use this procedure
to create a subnet.
