This RowStatus object controls the creation, modification, and deletion of a VPLS configuration table row, with the rule that none of the row's read-create objects can be changed while this status is active(1). Admins must first set this to notInService(2) to modify an active VPLS instance's settings, then set it back to active(1) to re-initiate signaling with the new values. For example, changing a live VPLS service's MAC learning setting requires transitioning vplsRowStatus to notInService, applying the change, then restoring it to active.
