How to Create Global and Island VLANs

The Policy tab VLANs left-panel tab used for access control are displayed in the Access Control Configuration window. If you have enabled the Policy VLAN Islands feature, there are two tabs in the VLANs tab: Global VLANs and Policy VLAN Islands . Otherwise, only the Global VLANs folder is displayed. For more information on Policy VLAN Islands, see How to Create a Policy VLAN Island.

The Policy tab provides you with one Global Default VLAN, available when you first access the Policy tab. You can create additional VLANs by selecting the Create VLAN option available when you right-click on the Global VLANs tab.

Once a VLAN is created, you can use it as follows:

  • as the default access control for a role, using the role General tab.
  • as an access control action for a rule using the Rule tab.
  • as an access control action for an automated service, using the Automated Service tab.
  • in a Policy VLAN Island, if that feature is enabled.

See Create VLAN Window and Roles for additional information.
