### About Network Infrastructure and VLANs on Oracle Database Appliance

Learn about networks and virtual local area networks (VLANs) on the appliance.

Oracle Database Appliance has two dual-port public network interfaces (either copper or fiber), which are bonded. For dual-port networks cards, the bonded network interface used for primary public network is always `btbond1`. You can, optionally, configure upto six bonded interfaces, `btbond1` to `btbond6`. If you use network cards with four ports, then you can select either `btbond1` or `btbond2` as the public network interface.

You can use the Browser User Interface to display all physical and virtual networks. You can use ODACLI commands or the Browser User Interface to create, update, and deleted networks.

Virtual Local Area Networks (VLANs)

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, providing 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 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.

The network interfaces differ, depending on your Oracle Database Appliance hardware. The VLAN is created on `btbond0` in single-node and high-availability platforms. In all cases, 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:

To use VLANs with Oracle Database Appliance, you must configure the VLANs before you deploy the appliance.

The Browser User Interface enables you to create, list, and delete VLANs on the appliance. For high-availability systems, you can use the Browser User Interface to create a VLAN on both nodes of the appliance. To create a VLAN on a specific node, use the command-line interface.

For a bare metal deployment, use the Browser User Interface or `odacli` commands to manage the following types of VLANs:

- Data Guard: For Oracle Data Guard.
- Database: For Oracle Database.

- Backup: For backup operations.

- Management: For management traffic.

- Other: For usage defined by the customer. For example, for applications.

The public VLAN is setup when you configure the first network using the command `odacli configure-firstnet`. You can set up only one public VLAN. Use the command-line interface to create other VLANs. For high-availability 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.
