How to Create
a Policy VLAN Island

VLAN islands enable you to set up, for example, a guest VLAN that restricts the guests in one facility from communicating with guests in another facility. It is recommended that you use the Policy VLAN Islands Configuration Wizard for creating and configuring the VLAN islands and selecting the devices for each island. To modify a VLAN island, use the VLAN island and Local VLAN tabs. See Policy VLAN Islands for more information.

Enabling/Disabling Policy VLAN Islands

In order to create local VLANs and use Policy VLAN Islands, you must first enable the Policy VLAN Islands feature. To do this, select Edit from the menu bar and check the Policy VLAN Islands Enabled checkbox. This creates a Policy VLAN Islands folder and one Default VLAN Island on the left panel Network Elements tab. Also, on the left panel VLANs tab, a Local VLANs folder is created.

To disable Policy VLAN Islands, select Edit from the menu bar and uncheck the Policy VLAN Islands Enabled checkbox. This removes the Policy VLAN Islands folder, and the information within it, from the Network Elements tab. It also removes the Local VLANs folder from the VLANs tab, and any local VLANs you have created are converted to global VLANs, using the corresponding VIDs from the VLAN island.

Since Policy VLAN information is lost if you disable the Policy VLAN Islands feature, if you plan to re-enable Policy VLAN Islands at a later time, you may wish to save the .pmd file containing the VLAN islands and local VLANs, so that you can import the Policy VLAN Islands information rather than recreating it manually.

Using the Policy VLAN Islands
Configuration Wizard

The Policy VLAN Islands Configuration Wizard is a series of windows that leads you through the steps required to create and configure VLAN islands.

Note: VLANs used in VLAN islands must be Local VLANs. If you want to use an existing Global VLAN as a Local VLAN, change it on the VLAN's General tab before starting the wizard.

  1. On the Edit menu, select the Policy VLAN Islands Enabled checkbox.
  2. In the left panel, select the Network Elements tab.
  3. Right-click the Policy VLAN Islands folder and select Policy VLAN Islands Configuration Wizard from the menu.
  4. In the Island Base ID window, enter the VLAN ID at which the creation of VIDs for the local VLANs will start. Click Next.
  5. In the Island Offset window, enter the number of VLANs you want to allocate for each VLAN island. Click Next.
  6. In the Local VLAN Naming Convention window, choose a format for the island VLAN names. Click Next.
  7. In the VLAN Islands window, add or remove VLAN Islands as needed. (The Default Island that is created when you enable the Policy VLAN Islands feature cannot be removed.) To add an island, enter the name to the left of the Add button and click Add. To remove an island, highlight it in the table and click Remove. When you have finished adding/removing islands, click Next.
  8. In the Local VLANs window, if you want to add any new local VLANs to use in VLAN islands, click New to open the Create VLAN window. Clicking OK on the Create VLAN window returns you to the wizard. When you have finished adding local VLANs, click Next.
  9. In the Island Devices window, add the devices to the islands as needed (see Add/Remove Devices window for more information).
  10. Click Finish.
  11. You can add a description of a VLAN island on the island's General tab.

Modifying a VLAN Island

Once you've created a VLAN island, you can change its characteristics using the right-panel tabs as follows:

Deleting a VLAN Island

You cannot delete the Default Island.

  1. Open the Network Elements tab in the left panel and expand the Policy VLAN Islands folder.
  2. Right-click the island you want to delete and select Delete.
  3. Click Yes to confirm the deletion.
