If your switching infrastructure supports VLANs and you have opted to make use of them, you are able to perform traffic separation across each VLAN regardless of the number of actual physical network ports that are available within each of your servers. Nonetheless, different VLAN segments may be available on different ports or bonds that you may have already configured.
Therefore, for each server, you should list the VLAN segment IDs on each port or bond. Make a note of the IP address and subnet information for each VLAN segment. If your network traffic is routed, also include the default gateway IP address here.
Once you have a list of ports or bonds and the VLAN segments that belong to them, you have the information that you need to define your VLAN Interfaces within Oracle VM. List the VLAN Interfaces that you intend to create for each server pool. Within this list, assign each VLAN Interface to the logical networks that you intend to create. For each logical network, list the channels that the network can support. Ensure that the components that are used within each channel of the network are all physically connected to the same network and that the VLAN segments on each NIC are configured correctly on your switches.
With all of this information, you are ready to begin configuration. It is important to bear the following points in mind:
All servers that you wish to include in a network must have already been discovered in Oracle VM Manager
If you are using network bonds, you must create these on each of your servers before you begin adding networks or creating VLAN Interfaces
You must create VLAN Interfaces before you start adding networks
When creating a VLAN Interface, you provide the following information:
The port on the server where VLAN traffic for the VLAN ID or segment is routed.
The VLAN ID that the VLAN Interface should handle.
And, optionally, the IP address to assign to each port or VLAN interface.
Note that when actually creating VLAN Interfaces for a server, the Oracle VM Manager Web Interface provides the facility to generate multiple VLAN Interfaces for a range of VLAN IDs in a single step, reducing the amount of work involved in configuring each VLAN segment.
When creating the network do not specify any ports or bonds to add to the network. Instead, add the appropriate VLAN interfaces to the network.
