About Managing Networks

Create and manage virtual local area networks (VLANs) to provide network security isolation for multiple workloads that share a common network.

Oracle Database Appliance supports multiple virtual local area networks (VLANs) on the same network port or bond. VLANs are multiple logical networks that are created from a single physical network switch port. Each VLAN acts as an independent logical network operating with other VLANs over the same physical connection. The VLAN tag associated with the data packet and network define the network. You can create a collection of isolated networks to enhance network security and bandwidth and keep data packets separated. For example, application, backup, and management networks.

You can create VLANs using either the copper ports or SFP+ fiber physical ports for the network. You cannot add host bus adapters (HBA). The network interfaces differ, depending on your Oracle Database Appliance hardware. The physical ports in the system at deployment (either copper or fiber) are bonded as btbond0 in single node platforms and bond0 in multi-node platforms. Depending on the platform, the VLANs are created on btbond0 or bond0.

Managing Virtual Local Area Networks (VLANs)

The command-line interface enables you to create, list, and delete VLANs. For a bare metal deployment, use the odaadmcli commands to manage the following types of VLANs:

  • Public: For public access. This is the default public interface.

  • Backup: For backup operations.

  • Management: For management traffic.

  • Custom: For usage defined by the customer. For example, for applications.

The public VLAN is setup when you configure the first network using the command configure-firstnet. You can set up only one public VLAN. Use the command-line interface to create other VLANs. For multi-node systems, the IP addresses for Node 0 and Node 1 cannot be the same. Oracle Database Appliance does not support Dynamic Host Configuration Protocol (DHCP) to provide IP addresses, subnet mask and default gateway.

You can use the command-line interface to list all networks, or use the Web Console to display all physical and virtual networks.

Viewing Configured Networks and Network Interfaces

Use the Web Console to display a list of configured networks, network details and interfaces.

  1. Click the Appliance tab in the Web Console.
  2. Click the Network tab in the left navigation to display a list of configured networks.
    When the appliance is a multi-node system, tabs named Node0 and Node1 appear in the right corner, below the Refresh button. Click a tab to display network details for each node.
  3. Click Show Interfaces in the upper left corner of the Network page to display a list of network interfaces.
    When the appliance is a multi-node system, tabs named Node0 and Node1 appear in the right corner, below the Refresh button. Click a tab to display the interfaces for each node.
  4. Click Show Networks to go back to the network view.

Creating a Network

Create a new network for the appliance.

When naming a network, you can use alphanumeric characters, dashes (-) and underscores (_). The network name cannot exceed 40 characters and must begin with an alpha character.
  1. Click the Appliance tab in the Web Console.
  2. Click the Network tab in the left navigation to display a list of configured networks.
  3. If the appliance is a multi-node system, click Node0 or Node1 to display the node where the network to reside.
  4. Click Create Network in the upper right corner.
  5. Enter the network information in the required fields. The Interface field has a drop-down menu with available choices. The Subnet Mask field has a drop-down menu with available choices and a search box. Optionally, enter a Gateway IP address and select an option from the Network Type list. The network type helps to identify if the network is for backup, database, dataguard, management, private, or other. Click Create.

Updating a Network

Update a network to revise the IP address, subnet mask, gateway, or type of network.

  1. Click the Appliance tab in the Web Console.
  2. Click the Network tab in the left navigation to display a list of configured networks.
    When the appliance is a multi-node system, tabs named Node0 and Node1 appear in the right corner, below the Refresh button. Click a tab to display network details for each node.
  3. If the appliance is a multi-node system, click Node0 or Node1 to display the node where the network that you want to edit resides.
  4. Expand the Actions menu, then click Update for the network that you want to edit.
  5. Update the information in the IP Address, Subnet Mask, and Gateway fields and select a network type from the list, as needed, then click Update.

Deleting a Network

Delete a configured network.

  1. Click the Appliance tab in the Web Console.
  2. Click the Network tab in the left navigation to display a list of configured networks.
    When the appliance is a multi-node system, tabs named Node0 and Node1 appear in the right corner, below the Refresh button. Click a tab to display network details for each node.
  3. If the appliance is a multi-node system, click Node0 or Node1 to display the node where the network that you want to delete resides.
  4. Expand the Actions menu, then click Delete for the network that you want to delete.
  5. Confirm the action when prompted.
