Enabling Fabric Assist

You can enable or disable Fabric Assist at the Service Definitions level only.

Service definitions contain groups of service application templates that you can apply to fabric-enabled devices. When you map a service definition to a site, the service applications are shared by the fabric-enabled devices within the site.

To enable the automatic creation of L2 VSN services, you must enter a Service ID Offset in the L2 VSN dialog.


After you configure a valid offset, the Fabric Assist Enabled check box becomes available to check. When checked (enabled), Fabric Assist automatically creates a corresponding C-VLAN entry for every VLAN that is not already mapped to an existing L2 VSN C-VLAN entry. Fabric Assist also creates an L2 VSN C-VLAN entry for any new VLANs created in the service application.

  NOTES:
  • The Service ID Offset determines the L2 VSN Service ID Range, which is from the offset value to the offset plus 4094.
  • A valid Service ID Offset cannot contain the Service ID for an existing L2 VSN that falls within the Service ID Range.
  • When enabled, Fabric Assist disables the Service ID Offset field and the Edit and Delete buttons to prevent any changes to L2 VSN services.

Fabric Assist displays the Service ID Range. For example, if the Service ID Offset is 1000, the Service ID Range will be from 1001 to 5094.

Fabric Assist displays the L2 VSN configuration information, including the Service ID, in the service application window. Any changes to Fabric Assist go into effect when you save the service definition.
