The Oracle Virtual Compute Appliance network infrastructure supports the use of VLANs by default. For this purpose, the Oracle Fabric Interconnect F1-15 Director Switches are set to trunking mode to allow tagged data traffic. You may implement VLANs for logical separation of different network segments, or to define security boundaries between networks with different applications – just as you would with physical servers instead of virtual machines.
However, to allow virtual machines hosted by the Oracle Virtual Compute Appliance to communicate with systems external to the appliance, you must update the configuration of your next-level data center switches accordingly.
The switch ports on the receiving end of the outbound appliance connections must be part of each VLAN used within the Oracle Virtual Compute Appliance environment.
The same ports must also be part of the network(s) connecting the external systems that your virtual machines need to access. For example, WAN connectivity implies that virtual machines are able to reach the public gateway in your data center. As an alternative to VLAN tagging, Layer 3 routing can be used to connect to the Oracle Virtual Compute Appliance.
