This is the RowStatus control for creating or deleting the binding between a physical or logical interface and a virtual context; setting it to createAndGo is what actually assigns an interface into a context, and setting it to destroy removes that interface from the context. Operationally this is the step that determines which traffic a given virtual context actually sees, since a context with no interfaces mapped to it processes nothing. An admin moving interface GigabitEthernet1/1 into a new 'Finance-DMZ-Context' would use this object to formally attach it after the context itself was already created.
