This read-create INTEGER (invalid, active, or inactive) governs whether a Frame Relay virtual circuit exists and is operational within this FRoIP context; in the absence of a Data Link Connection Management Interface, setting this to active creates the row and setting it to invalid deletes it, though implementations may leave the row visible as invalid for some time. An admin manually provisions a permanent virtual circuit by setting this to active(2) when there's no LMI-based auto-provisioning available. For example, on a static configuration without DLCMI, the admin creates a new DLCI entry by setting this circuit state object directly to active.
