+ DESCRIPTION
+ "Represents textual information taken from the NVT ASCII
+
+ character set, as defined in pages 4, 10-11 of RFC 854.
+
+ To summarize RFC 854, the NVT ASCII repertoire specifies:
+
+ - the use of character codes 0-127 (decimal)
+
+ - the graphics characters (32-126) are interpreted as
+ US ASCII
+
+ - NUL, LF, CR, BEL, BS, HT, VT and FF have the special
+ meanings specified in RFC 854
+
+ - the other 25 codes have no standard interpretation
+
+ - the sequence 'CR LF' means newline
+
+ - the sequence 'CR NUL' means carriage-return
+
+ - an 'LF' not preceded by a 'CR' means moving to the
+ same column on the next line.
+
+ - the sequence 'CR x' for any x other than LF or NUL is
+ illegal. (Note that this also means that a string may
+ end with either 'CR LF' or 'CR NUL', but not with CR.)

+ DESCRIPTION
+ "Represents integer-valued information used for atomic
+ operations. When the management protocol is used to specify
+ that an object instance having this syntax is to be
+ modified, the new value supplied via the management protocol
+ must precisely match the value presently held by the
+ instance. If not, the management protocol set operation
+ fails with an error of `inconsistentValue'. Otherwise, if
+ the current value is the maximum value of 2^31-1 (2147483647
+ decimal), then the value held by the instance is wrapped to
+ zero; otherwise, the value held by the instance is
+ incremented by one. (Note that regardless of whether the
+ management protocol set operation succeeds, the variable-
+ binding in the request and response PDUs are identical.)
+
+ The value of the ACCESS clause for objects having this
+ syntax is either `read-write' or `read-create'. When an
+ instance of a columnar object having this syntax is created,
+ any value may be supplied via the management protocol.
+
+ When the network management portion of the system is re-
+ initialized, the value of every object instance having this
+ syntax must either be incremented from its value prior to
+ the re-initialization, or (if the value prior to the re-
+ initialization is unknown) be set to a pseudo-randomly
+ generated value."

+ DESCRIPTION
+ "A pointer to either a specific instance of a MIB object or

+ particular instance of the first accessible columnar object
+ in the conceptual row.
+
+ The two uses of this textual convention are replaced by
+ VariablePointer and RowPointer, respectively."
+ SYNTAX OBJECT IDENTIFIER
+
+VariablePointer ::= TEXTUAL-CONVENTION
+ STATUS current
+ DESCRIPTION
+ "A pointer to a specific object instance. For example,
+ sysContact.0 or ifInOctets.3."
+ SYNTAX OBJECT IDENTIFIER
+
+RowPointer ::= TEXTUAL-CONVENTION
+ STATUS current
+ DESCRIPTION
+ "Represents a pointer to a conceptual row. The value is the
+ name of the instance of the first accessible columnar object
+ in the conceptual row.
+
+ For example, ifIndex.3 would point to the 3rd row in the
+ ifTable (note that if ifIndex were not-accessible, then
+ ifDescr.3 would be used instead)."
+ SYNTAX OBJECT IDENTIFIER
+
+RowStatus ::= TEXTUAL-CONVENTION
+ STATUS current
+ DESCRIPTION
+ "The RowStatus textual convention is used to manage the
+ creation and deletion of conceptual rows, and is used as the
+ value of the SYNTAX clause for the status column of a
+ conceptual row (as described in Section 7.7.1 of [2].)
+
+ 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); 'notInService' has
+ no implication regarding the internal consistency of
+ the row, availability of resources, or consistency with
+ the current state of the managed device;
+
+ - `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 (i.e., one or more required columns in
+ the conceptual row have not been instanciated);
+
+ - `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 attempt 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').
+
+ NOTE WELL
+
+ This textual convention may be used for a MIB table,
+ irrespective of whether the values of that table's
+ conceptual rows are able to be modified while it is
+ active, or whether its conceptual rows must be taken
+ out of service in order to be modified. That is, it is
+ the responsibility of the DESCRIPTION clause of the
+ status column to specify whether the status column must
+ not be `active' in order for the value of some other
+ column of the same conceptual row to be modified. If
+ such a specification is made, affected columns may be
+ changed by an SNMP set PDU if the RowStatus would not
+ be equal to `active' either immediately before or after
+ processing the PDU. In other words, if the PDU also
+ contained a varbind that would change the RowStatus
+ value, the column in question may be changed if the
+ RowStatus was not equal to `active' as the PDU was
+ received, or if the varbind sets the status to a value
+ other than 'active'.
+
+ Also note that whenever any elements of a row exist, the
+ RowStatus column must also exist.
+
+ To summarize the effect of having a conceptual row with a
+ status column having a SYNTAX clause value of RowStatus,
+ consider the following state diagram:
+
+ STATE
+ +--------------+-----------+-------------+-------------
+ | A | B | C | D
+ | |status col.|status column|
+ |status column | is | is |status column

+
+ (1) goto B or C, depending on information available to the
+ agent.
+
+ (2) if other variable bindings included in the same PDU,
+ provide values for all columns which are missing but
+ required, and all columns have acceptable values, then
+ return noError and goto D.
+
+ (3) if other variable bindings included in the same PDU,
+ provide legal values for all columns which are missing but
+ required, then return noError and goto C.
+
+ (4) at the discretion of the agent, the return value may be
+ either:
+
+ inconsistentName: because the agent does not choose to
+ create such an instance when the corresponding
+ RowStatus instance does not exist, or
+
+ inconsistentValue: if the supplied value is
+ inconsistent with the state of some other MIB object's
+ value, or
+
+ noError: because the agent chooses to create the
+ instance.
+
+ If noError is returned, then the instance of the status
+ column must also be created, and the new state is B or C,
+ depending on the information available to the agent. If
+ inconsistentName or inconsistentValue is returned, the row
+ remains in state A.
+
+ (5) depending on the MIB definition for the column/table,
+ either noError or inconsistentValue may be returned.
+
+ (6) the return value can indicate one of the following
+ errors:
+
+ wrongValue: because the agent does not support
+ notInService (e.g., an agent which does not support
+ createAndWait), or
+
+ inconsistentValue: because the agent is unable to take
+ the row out of service at this time, perhaps because it
+ is in use and cannot be de-activated.
+
+ (7) the return value can indicate the following error:
+
+ inconsistentValue: because the agent is unable to
+ remove the row at this time, perhaps because it is in
+ use and cannot be de-activated.
+
+ (8) the transition to D can fail, e.g., if the values of the
+ conceptual row are inconsistent, then the error code would
+ be inconsistentValue.
+
+ NOTE: Other processing of (this and other varbinds of) the
+ set request may result in a response other than noError
+ being returned, e.g., wrongValue, noCreation, etc.
+
+ Conceptual Row Creation
+
+ There are four potential interactions when creating a
+ conceptual row: selecting an instance-identifier which is
+ not in use; creating the conceptual row; initializing any
+ objects for which the agent does not supply a default; and,
+ making the conceptual row available for use by the managed
+ device.
+
+ Interaction 1: Selecting an Instance-Identifier
+
+ The algorithm used to select an instance-identifier varies
+ for each conceptual row. In some cases, the instance-
+ identifier is semantically significant, e.g., the
+ destination address of a route, and a management station
+ selects the instance-identifier according to the semantics.
+
+ In other cases, the instance-identifier is used solely to
+ distinguish conceptual rows, and a management station
+ without specific knowledge of the conceptual row might
+ examine the instances present in order to determine an
+ unused instance-identifier. (This approach may be used, but
+ it is often highly sub-optimal; however, it is also a
+ questionable practice for a naive management station to
+ attempt conceptual row creation.)
+
+ Alternately, the MIB module which defines the conceptual row
+ might provide one or more objects which provide assistance
+ in determining an unused instance-identifier. For example,
+ if the conceptual row is indexed by an integer-value, then
+ an object having an integer-valued SYNTAX clause might be
+ defined for such a purpose, allowing a management station to
+ issue a management protocol retrieval operation. In order
+ to avoid unnecessary collisions between competing management
+ stations, `adjacent' retrievals of this object should be
+ different.
+
+ Finally, the management station could select a pseudo-random
+ number to use as the index. In the event that this index
+
+ was already in use and an inconsistentValue was returned in
+ response to the management protocol set operation, the
+ management station should simply select a new pseudo-random
+ number and retry the operation.
+
+ A MIB designer should choose between the two latter
+ algorithms based on the size of the table (and therefore the
+ efficiency of each algorithm). For tables in which a large
+ number of entries are expected, it is recommended that a MIB
+ object be defined that returns an acceptable index for
+ creation. For tables with small numbers of entries, it is
+ recommended that the latter pseudo-random index mechanism be
+ used.
+
+ Interaction 2: Creating the Conceptual Row
+
+ Once an unused instance-identifier has been selected, the
+ management station determines if it wishes to create and
+ activate the conceptual row in one transaction or in a
+ negotiated set of interactions.
+
+ Interaction 2a: Creating and Activating the Conceptual Row
+
+ The management station must first determine the column
+ requirements, i.e., it must determine those columns for
+ which it must or must not provide values. Depending on the
+ complexity of the table and the management station's
+ knowledge of the agent's capabilities, this determination
+ can be made locally by the management station. Alternately,
+ the management station issues a management protocol get
+ operation to examine all columns in the conceptual row that
+ it wishes to create. In response, for each column, there
+ are three possible outcomes:
+
+ - a value is returned, indicating that some other
+ management station has already created this conceptual
+ row. We return to interaction 1.
+
+ - the exception `noSuchInstance' is returned,
+ indicating that the agent implements the object-type
+ associated with this column, and that this column in at
+ least one conceptual row would be accessible in the MIB
+ view used by the retrieval were it to exist. For those
+ columns to which the agent provides read-create access,
+ the `noSuchInstance' exception tells the management
+ station that it should supply a value for this column
+ when the conceptual row is to be created.
+
+ - the exception `noSuchObject' is returned, indicating
+ that the agent does not implement the object-type
+ associated with this column or that there is no
+ conceptual row for which this column would be
+ accessible in the MIB view used by the retrieval. As
+ such, the management station can not issue any
+ management protocol set operations to create an
+ instance of this column.
+
+ Once the column requirements have been determined, a
+ management protocol set operation is accordingly issued.
+ This operation also sets the new instance of the status
+ column to `createAndGo'.
+
+ When the agent processes the set operation, it verifies that
+ it has sufficient information to make the conceptual row
+ available for use by the managed device. The information
+ available to the agent is provided by two sources: the
+ management protocol set operation which creates the
+ conceptual row, and, implementation-specific defaults
+ supplied by the agent (note that an agent must provide
+ implementation-specific defaults for at least those objects
+ which it implements as read-only). If there is sufficient
+ information available, then the conceptual row is created, a
+ `noError' response is returned, the status column is set to
+ `active', and no further interactions are necessary (i.e.,
+ interactions 3 and 4 are skipped). If there is insufficient
+ information, then the conceptual row is not created, and the
+ set operation fails with an error of `inconsistentValue'.
+ On this error, the management station can issue a management
+ protocol retrieval operation to determine if this was
+ because it failed to specify a value for a required column,
+ or, because the selected instance of the status column
+ already existed. In the latter case, we return to
+ interaction 1. In the former case, the management station
+ can re-issue the set operation with the additional
+ information, or begin interaction 2 again using
+ `createAndWait' in order to negotiate creation of the
+ conceptual row.
+
+ NOTE WELL
+
+ Regardless of the method used to determine the column
+ requirements, it is possible that the management
+ station might deem a column necessary when, in fact,
+ the agent will not allow that particular columnar
+ instance to be created or written. In this case, the
+ management protocol set operation will fail with an
+ error such as `noCreation' or `notWritable'. In this
+ case, the management station decides whether it needs
+ to be able to set a value for that particular columnar
+ instance. If not, the management station re-issues the
+ management protocol set operation, but without setting
+ a value for that particular columnar instance;
+ otherwise, the management station aborts the row
+ creation algorithm.
+
+ Interaction 2b: Negotiating the Creation of the Conceptual
+ Row
+
+ The management station issues a management protocol set
+ operation which sets the desired instance of the status
+ column to `createAndWait'. If the agent is unwilling to
+ process a request of this sort, the set operation fails with
+ an error of `wrongValue'. (As a consequence, such an agent
+ must be prepared to accept a single management protocol set
+ operation, i.e., interaction 2a above, containing all of the
+ columns indicated by its column requirements.) Otherwise,
+ the conceptual row is created, a `noError' response is
+ returned, and the status column is immediately set to either
+ `notInService' or `notReady', depending on whether it has
+ sufficient information to (attempt to) make the conceptual
+ row available for use by the managed device. If there is
+ sufficient information available, then the status column is
+ set to `notInService'; otherwise, if there is insufficient
+ information, then the status column is set to `notReady'.
+ Regardless, we proceed to interaction 3.
+
+ Interaction 3: Initializing non-defaulted Objects
+
+ The management station must now determine the column
+ requirements. It issues a management protocol get operation
+ to examine all columns in the created conceptual row. In
+ the response, for each column, there are three possible
+ outcomes:
+
+ - a value is returned, indicating that the agent
+ implements the object-type associated with this column
+ and had sufficient information to provide a value. For
+ those columns to which the agent provides read-create
+ access (and for which the agent allows their values to
+ be changed after their creation), a value return tells
+ the management station that it may issue additional
+ management protocol set operations, if it desires, in
+ order to change the value associated with this column.
+
+ - the exception `noSuchInstance' is returned,
+ indicating that the agent implements the object-type
+ associated with this column, and that this column in at
+ least one conceptual row would be accessible in the MIB
+ view used by the retrieval were it to exist. However,
+ the agent does not have sufficient information to
+ provide a value, and until a value is provided, the
+ conceptual row may not be made available for use by the
+ managed device. For those columns to which the agent
+ provides read-create access, the `noSuchInstance'
+ exception tells the management station that it must
+ issue additional management protocol set operations, in
+ order to provide a value associated with this column.
+
+ - the exception `noSuchObject' is returned, indicating
+ that the agent does not implement the object-type
+ associated with this column or that there is no
+ conceptual row for which this column would be
+ accessible in the MIB view used by the retrieval. As
+ such, the management station can not issue any
+ management protocol set operations to create an
+ instance of this column.
+
+ If the value associated with the status column is
+ `notReady', then the management station must first deal with
+ all `noSuchInstance' columns, if any. Having done so, the
+ value of the status column becomes `notInService', and we
+ proceed to interaction 4.
+
+ Interaction 4: Making the Conceptual Row Available
+
+ 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'. If the agent has sufficient information to
+ make the conceptual row available for use by the managed
+ device, the management protocol set operation succeeds (a
+ `noError' response is returned). Otherwise, the management
+ protocol set operation fails with an error of
+ `inconsistentValue'.
+
+ NOTE WELL
+
+ A conceptual row having a status column with value
+ `notInService' or `notReady' is unavailable to the
+ managed device. As such, it is possible for the
+ managed device to create its own instances during the
+ time between the management protocol set operation
+ which sets the status column to `createAndWait' and the
+ management protocol set operation which sets the status
+ column to `active'. In this case, when the management
+ protocol set operation is issued to set the status
+ column to `active', the values held in the agent
+ supersede those used by the managed device.
+
+ If the management station is prevented from setting the
+ status column to `active' (e.g., due to management station
+ or network failure) the conceptual row will be left in the
+ `notInService' or `notReady' state, consuming resources
+ indefinitely. The agent must detect conceptual rows that
+ have been in either state for an abnormally long period of
+ time and remove them. It is the responsibility of the
+ DESCRIPTION clause of the status column to indicate what an
+ abnormally long period of time would be. This period of
+ time should be long enough to allow for human response time
+ (including `think time') between the creation of the
+ conceptual row and the setting of the status to `active'.
+ In the absence of such information in the DESCRIPTION
+ clause, it is suggested that this period be approximately 5
+ minutes in length. This removal action applies not only to
+ newly-created rows, but also to previously active rows which
+ are set to, and left in, the notInService state for a
+ prolonged period exceeding that which is considered normal
+ for such a conceptual row.
+
+ Conceptual Row Suspension
+
+ When a conceptual row is `active', the management station
+ may issue a management protocol set operation which sets the
+ instance of the status column to `notInService'. If the
+ agent is unwilling to do so, the set operation fails with an
+ error of `wrongValue' or `inconsistentValue'. Otherwise,
+ the conceptual row is taken out of service, and a `noError'
+ response is returned. It is the responsibility of the
+ DESCRIPTION clause of the status column to indicate under
+ what circumstances the status column should be taken out of
+ service (e.g., in order for the value of some other column
+ of the same conceptual row to be modified).
+
+ Conceptual Row Deletion
+
+ For deletion of conceptual rows, a management protocol set
+ operation is issued which sets the instance of the status
+ column to `destroy'. This request may be made regardless of
+ the current value of the status column (e.g., it is possible
+ to delete conceptual rows which are either `notReady',
+ `notInService' or `active'.) If the operation succeeds,
+ then all instances associated with the conceptual row are
+ immediately removed."

+ STATUS current
+ DESCRIPTION
+ "Describes the memory realization of a conceptual row. A
+ row which is volatile(2) is lost upon reboot. A row which
+ is either nonVolatile(3), permanent(4) or readOnly(5), is
+ backed up by stable storage. A row which is permanent(4)
+ can be changed but not deleted. A row which is readOnly(5)
+ cannot be changed nor deleted.
+
+ If the value of an object with this syntax is either
+ permanent(4) or readOnly(5), it cannot be written.
+ Conversely, if the value is either other(1), volatile(2) or
+ nonVolatile(3), it cannot be modified to be permanent(4) or
+ readOnly(5). (All illegal modifications result in a
+ 'wrongValue' error.)
+
+ Every usage of this textual convention is required to
+ specify the columnar objects which a permanent(4) row must
+ at a minimum allow to be writable."

+TAddress ::= TEXTUAL-CONVENTION
+ STATUS current
+ DESCRIPTION
+ "Denotes a transport service address.
+
+ A TAddress value is always interpreted within the context of a
+ TDomain value. Thus, each definition of a TDomain value must
+ be accompanied by a definition of a textual convention for use
+ with that TDomain. Some possible textual conventions, such as
+ SnmpUDPAddress for snmpUDPDomain, are defined in the SNMPv2-TM
+ MIB module. Other possible textual conventions are defined in
+ other MIB modules."
