About Network Infrastructure and VLANs on Oracle Database Appliance

Oracle Database Appliance supports multiple VLANs on the same network port or bond.

Virtual local area networks (VLANs) are multiple logical networks that are created from a single physical network switch port. VLANs provide network security isolation for multiple workloads that share a common network. For example, application, backup, and management networks. Each VLAN acts as an independent logical network operating with other VLANs over the same physical connection.

The physical ports in the system at deployment (either copper or fiber) are bonded as btbond0 in single node platforms. The VLAN is created on btbond0.

Connections to user domains are through the selected interfaces. A switch that supports tagged VLANs uses VLAN IDs to identify the packet, including to which network the packet belongs.

Note:

You cannot modify the Public and Private-interfaces after the system is deployed. To use VLANs with Oracle Database Appliance, you must configure them before you deploy the appliance. 

Use the Browser User Interface to display all physical and virtual networks. Use the command-line interface to create, list, and delete VLANs.

Viewing Configured Networks

Use the Browser User Interface to display a list of configured networks and network details.

1. Log into the Browser User Interface.
2. Click the Network tab.
   You can view network details, create a new network, update an existing network, and delete a network.

Creating a Network

Use the Browser User Interface to create networks in Oracle Database Appliance.

The Browser User Interface provides a quick and easy method of creating networks. You can create the following types of networks: Public, Private, Dataguard, Backup, and Other.

1. Open a browser and enter the following URL to launch the Browser User Interface:
   https://ip-address:7093/mgmt/index.html
2. Login as oda-admin.
3. Click the Network tab.
4. Click Create Network to display the Create New Network page.
5. Enter the following information on the Create New Network page to configure the network:
   1. In theIP Address field, enter the network’s IP address.
   2. In the Interface field, select an interface from the menu.
   3. In the Subnet Mask field, enter the subnet mask.
   4. In the Network Type field, select an option from the drop-down list. The options are: Public, Private, Dataguard, Backup, and Other.
   5. In the Gateway field, enter the gateway. The gateway is required for the default network.
   6. For the Default Network, select Yes or No to identify whether or not the network is the default network.
6. Click Create. When prompted, click Yes to confirm that you want to start the job to create the network.

Updating a Network

Use the Browser User Interface to update an existing network configuration.

1. Open a browser and enter the following URL to launch the Browser User Interface:
   https://ip-address:7093/mgmt/index.html
2. Login as oda-admin.
3. Click the Network tab.
4. Select Update from the Actions menu next to the network you want to update.
5. Edit the fields, as needed, on the Update Network page to update the network configuration:
   1. In the IP Address field, enter the network’s IP address.
   2. In the Interface field, enter the name of the network interface.
   3. In the Subnet Mask field, enter the subnet mask.
   4. In the Network Type field, select an option from the drop-down list. The default is Other.
   5. In the Gateway field, enter the gateway. The gateway is required for the default network.
   6. For the Default Network, select Yes or No to identify whether or not the network is the default network.
6. Click Update. When prompted, click Yes to confirm that you want to start the job to update the network.

Deleting a Network

Use the Browser User Interface to delete a specific network.

Note:

You can only delete networks that are not public or private networks. The delete option is disabled for the private and public networks.

1. Open a browser and enter the following URL to launch the Browser User Interface:
   https://ip-address:7093/mgmt/index.html
2. Login as oda-admin.
3. Click the Network tab.
4. Select Delete from the Actions menu next to a network entry.
