5.2 VLAN Interfaces

The VLAN Interfaces tab allows you to define and manage VLAN interfaces on your Oracle VM Servers [2] . If your network is configured to support VLANs, you should define interfaces for your different VLAN IDs on each of your servers, so that you are able to define Oracle VM networks that take advantage of VLAN separation.

The VLAN Interfaces tab is divided into two sections, a Navigation Pane and a Management Pane displaying a tabular view of the VLAN Interfaces associated with the item selected in the navigation pane.

5.2.1 Navigation Pane

The Navigation Pane displayed on the VLAN Interfaces tab is used to control the VLAN interfaces that are displayed in the Management Pane. The Navigation Pane presents a tree view of the server objects that have been discovered within your environment. Servers are grouped by Server Pools or are automatically presented beneath the node titled Unassigned Servers.

Expanding the Server Pools node, allows you to see each of the server pools configured within your environment. Selecting a particular server pool from the list presented, updates the Management Pane to show only the VLAN interfaces configured for that server pool.

Clicking on the Unassigned Servers node is equivalent to selecting an individual server pool. The Management Pane is updated to show only the VLAN interfaces configured for servers that do not belong to a server pool.

Both the Unassigned Servers node and any of the server pool nodes can be further expanded to list the servers that belong to these nodes. The VLAN interfaces displayed in the Management Pane can be further limited to each individual server listed.

Finally, you are able to expand server nodes to list the ports or bonds that are available for each server. By selecting a particular port for any server in the Navigation Pane, the list of VLAN interfaces presented in the Management Pane is limited to those interfaces configured for that specific port or bond.

5.2.2 Management Pane

The Management Pane on the VLAN Interface tab allows you to create, edit or delete VLAN interfaces configured within Oracle VM Manager. VLAN interfaces are listed in a tabular view that includes a toolbar providing options to manage interfaces. The VLAN Interfaces that are displayed in the table at any point in time are controlled using the Navigation Pane.

The VLAN Interface tab includes a toolbar in the management pane that consists of the following options:

The table view in the VLAN Interface subtab includes the following fields:

  • Name: The name of the VLAN interface as defined in Oracle VM Manager.

  • VLAN ID: The VLAN ID that is assigned to the VLAN interface.

  • Server Pool: The server pool where this VLAN interface is located (if any).

  • Server: The server where the VLAN interface is located.

  • Port: The network port on which the VLAN interface is assigned.

  • MTU: The MTU value for the VLAN interface.

  • Network: The network that the VLAN interface is attached to (if any).

  • Addressing: A grouping of fields to display IP address assignment.

    • Type: Describes the network address assignment type (either Static, Dynamic or blank if None).

    • IP Address: The IP address allocated to the VLAN interface (if any).

    • Netmask: The netmask applied to the VLAN interface (if any).

  • Description: The description of the VLAN interface as defined in Oracle VM Manager.

5.2.3 Create VLAN Interfaces

If your environment is configured to use VLANs, you need to configure VLAN interfaces within Oracle VM Manager before you are able to use them within a network configuration.

To Create A VLAN Interface

  1. On the Networking tab, click the VLAN Interfaces subtab link.

  2. Click the Create VLAN Interface icon Create VLAN Interface icon in the toolbar.

  3. The Create VLAN Interface(s) dialog is displayed.

  4. A navigation tree similar to the one shown in the Navigation Pane is displayed in the pane on the right of the dialog. Use the navigation tree to identify server ports or bonds that are configured for your VLANs. You are able to expand nodes in the navigation tree to identify individual servers, and then expand each server to identify the ports that are available. Alongside each port, listed for a server, is a check box that allows you to enable the port to configure VLAN interfaces that are attached to it. You must select at least one port. Be careful not to select a port that is already in use or which is part of a bond. The user interface does not filter the ports to allow you to only select unused ports.

  5. Once you have selected the ports for which you wish to create VLAN interfaces, you can click Next to continue to the next stage of the wizard, or click Cancel to exit the wizard without making any changes.

  6. The Select VLAN IDs stage is displayed in the wizard. In the panel on the right, you are able to select a VLAN ID range. Using the two fields available you can specify a range of VLAN IDs that are configured on the network ports for which you are creating VLAN interfaces. Use the Add, Delete and Delete All buttons to manage the VLAN IDs for which VLAN interfaces should be created. A VLAN interface is created for each VLAN ID specified in the list provided here. You must select at least one VLAN ID.

  7. When you have finished selecting VLAN IDs, you can click Next to continue to the next stage of the wizard, or click Cancel to exit the wizard without making any changes.

  8. The Configure IP Address stage is displayed in the wizard. On the panel on the right, a table is presented listing each of the VLAN interfaces that have been created. For each VLAN interface listed, you are able to edit the MTU setting, the IP Address assignment settings and the description. The Addressing field provides a drop-down selector that allows you to choose either None, Static or Dynamic to specify how IP Addressing should be configured on this interface. If you select Static here, the IP Address and Mask fields become available to edit, otherwise they remain uneditable.

    A Filter By VLAN ID drop-down selector is provided at the top of the table, to allow you to quickly limit the VLAN interfaces displayed in the table to make changes in a more orderly fashion.

  9. Click Finish when you have finished editing VLAN interfaces to save the changes, or click Cancel to exit.

5.2.4 Edit VLAN Interfaces

To Edit A VLAN Interface

  1. On the Networking tab, click the VLAN Interfaces subtab link.

  2. Use the navigation pane to locate filter the list of VLAN interfaces displayed in the management pane.

  3. Select the VLAN interface that you wish to edit from the interfaces listed in the management pane.

  4. Click the Edit VLAN Interface icon Edit VLAN Interface icon in the toolbar.

  5. The Edit VLAN Interface(s) dialog is displayed.

  6. For each VLAN interface listed, you are able to edit the MTU setting, the IP Address assignment settings and the description. The Addressing field provides a drop-down selector that allows you to choose either None, Static or Dynamic to specify how IP Addressing should be configured on this interface. If you select Static here, the IP Address and Mask fields become available to edit, otherwise they remain uneditable.

  7. Click OK when you have finished editing VLAN interfaces to save the changes, or click Cancel to exit.

5.2.5 Delete VLAN Interfaces

To Delete A VLAN Interface

  1. On the Networking tab, click the VLAN Interfaces subtab link.

  2. Use the navigation pane to locate filter the list of VLAN interfaces displayed in the management pane.

  3. Select the VLAN interfaces that you wish to remove from Oracle VM Manager from the interfaces listed in the management pane.

  4. Click the Delete VLAN Interface(s) icon Delete VLAN Interface(s) icon at the top of the table displayed in the management pane.

  5. The Delete Confirmation dialog box is displayed. Click OK to delete the VLAN interface from Oracle VM Manager.



[2] VLAN configuration within Oracle VM Manager has changed significantly in Oracle VM 3.3. If you have used previous releases of Oracle VM, it is important that you understand these changes and it is recommended that you refer to Understanding Networks in the Oracle VM Concepts Guide.
