The value of tRPAdminPSFromCommExprRowStatus specifies the RowStatus for this row. To create a row, set this object to 'createAndGo(4)'. The value of tRPAdminPSFromCommExprString1 must be set to a non-empty string in the same SNMP SET PDU for the row creation to succeed. When tRPAdminControlApply is set to 'commit(3)', the row will actually be created in the tRPOperPSFromCommExprTable. When the value of this object is set to 'createAndWait(5)', a new entry is created with value of this object set to 'notInService(2)' and the tRPAdminPSFromCommExprString1-4 strings can be configured separately. When the value of this object is set to 'active(1)', the values of objects tRPAdminPSFromCommExprString1-4, are concatenated to form one expression of at most 900 characters. When tRPAdminControlApply is set to 'commit(3)', the row will actually be created in the tRPOperPSFromCommExprTable. To destroy a row, set this object to 'destroy(6)'. When tRPAdminControlApply is set to 'commit(3)', the row will actually be removed from the tRPOperPSFromCommExprTable.
