Fabric Assist L2 VSN Considerations

  • The following rules apply to service applications within the same service definition:
    • Service applications can have the same Service ID Offset because VLANs cannot be reused between service applications in the same service definition.
    • Service applications with different Service ID Offsets are valid as long as the Service ID Ranges do not overlap within the service definition.
  • When Fabric Assist is enabled, you can manually create L2 Switched or Transparent UNI services, but you can no longer manually create L2 VSN C-VLAN services through the Service Application dialog.
  • If you do not want a VLAN to have a service, create that VLAN at the site level. L2 VSNs that are created by Fabric Assist are based only on the VLANs in the service application window.
  • If you want to modify Fabric Assist, you must disable Fabric Assist by clearing the L2 VSN Enabled check box.
  IMPORTANT: Any C-VLAN entries that Fabric Assist created are automatically deleted from the L2 VSN window when you disable Fabric Assist.
