## Symptoms

- * Anti-Spoofing setting changes to "Undefined" when VSX cluster object is edited.  

* Policy installation fails with error:  

  "`The Topology information must be configured for object <Object Name>, interface <Interface Name>, in order to use the Anti-Spoofing feature`".  

* Changing the spoofing setting using GuiDBedit from "`undefined`" to "`this`" and installing the policy from SmartDashboard works around the issue.

## Cause
