This object is used to create a new row or modify or delete an existing row in this table.The status column has six defined values: The status column has six defined values: - 'active', which indicates that the conceptual row is available for use by the managed device; - 'notInService', which indicates that the conceptual row exists in the agent, but is unavailable for use by the managed device (see NOTE below); - 'notReady', which indicates that the conceptual row exists in the agent, but is missing information necessary in order to be available for use by the managed device; - 'createAndGo', which is supplied by a management station wishing to create a new instance of a conceptual row and to have its status automatically set to active, making it available for use by the managed device; - 'createAndWait', which is supplied by a management station wishing to create a new instance of a conceptual row (but not make it available for use by the managed device); and, - 'destroy', which is supplied by a management station wishing to delete all of the instances associated with an existing conceptual row. Whereas five of the six values (all except 'notReady') may be specified in a management protocol set operation, only three values will be returned in response to a management protocol retrieval operation: 'notReady', 'notInService' or 'active'. That is, when queried, an existing conceptual row has only three states: it is either available for use by the managed device (the status column has value 'active'); it is not available for use by the managed device, though the agent has sufficient information to make it so (the status column has value 'notInService'); or, it is not available for use by the managed device, and an attempt to make it so would fail because the agent has insufficient information (the state column has value 'notReady').
