MIB Reference 15use by the managed device, and which is suppliedby a management station wishing to exercise anon-line update of the existing conceptual row. For amanagement protocol set operation, a genErrresponse is returned when the row does not exist.createAndGo, which is supplied by a managementstation wishing to create a new instance of a con-ceptual row and to have its status automatically setto active, making it available for use by themanaged device. For a management protocol setoperation, a genErr response is returned when therow already exists.destroy, which is supplied by a management stationwishing to delete all of the instances associated withan existing conceptual row.Note that all of the above values may be specified in a man-agement protocol set operation, and only the active valuewill be returned in response to a management protocolretrieval operation. For a management protocol set opera-tion, if other variable bindings are included in the samePDU, then a genErr response is returned.::= { portLogicalX25AdminTable.1.5 }portLogicalX25OperTable (portX25Group.4)This table contains read-only variables that reflect the actual operating parametervalues. Unless a value was changed in the portLogicalX25AdminTable after the interfacebecame operational, the values in the portLogicalX25OperTable should match thoseconfigured in the portLogicalX25AdminTable. The variables in theportLogicalX25OperTable are listed below.portLogicalX25OperFrDlci (portLogicalX25OperTable.1.1)portLogicalX25OperCxnPriority (portLogicalX25OperTable.1.2)portLogicalX25OperRfc1490 (portLogicalX25OperTable.1.3)portLogicalX25OperBAG (portLogicalX25OperTable.1.4)portX25AdminTable (portX25Group.5)This is an Admin Table for both logical and physical ports. This table contains NetlinkEnterprise-specific objects to manage an X25 port. Changing one of these parametersmay take effect in the operating port immediately or may wait until the interface isrestarted depending on the details of the implementation. Most of the objects in thisread/write table have corresponding read-only objects in the portX25OperTable thatreturn the current operating value. The operating values may be different from these
