The object is used to manage the creation, activation and deletion of a conceptual row. This object only supports four of the six status columns defined by the SNMPv2-TC MIB. - `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; - `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. For conceptual row creation, the management station must issue a management protocol set operation which sets the instance of the status column to `createAndWait'. Once the management station is satisfied with the values associated with the columns of the conceptual row, it issues a management protocol set operation to set the status column to `active'. For deletion of conceptual rows, a management protocol set operation is issued which sets the instance of the status column to `destroy'.
