-- Changes:
--      Added import for BITS
--      Changed access of object netDefaultGateway from
--          read-create to read-write. (object is a scalar)
--
-- Problems:
--      1) The following rows do not have a consistent indexing scheme
--         as required by RFC 1902, section 7.8.1: protocolDistStatsEntry,
--         addressMapEntry, nlHostEntry, nlMatrixSDEntry, nlMatrixDSEntry,

        DESCRIPTION
            "This TC describes an object which counts events with the
            following semantics: objects of this type will be set to
            zero(0) on creation and will thereafter count appropriate
            events, wrapping back to zero(0) when the value 2^32 is
            reached.
    
            Provided that an application discovers the new object within
            the minimum time to wrap it can use the initial value as a
            delta since it last polled the table of which this object is
            part.  It is important for a management station to be aware of
            this minimum time and the actual time between polls, and to
            discard data if the actual time is too long or there is no
            defined minimum time.
    
            Typically this TC is used in tables where the INDEX space is
            constantly changing and/or the TimeFilter mechanism is in use."

            an otherwise undetectable discontinuity in the data."

        DESCRIPTION
            "To be used for the index to a table.  Allows an application
            to download only those rows changed since a particular time.
            A row is considered changed if the value of any object in the
            row changes or if the row is created or deleted.
    
            When sysUpTime is equal to zero, this table shall be empty.
    
            One entry exists for each past value of sysUpTime, except that
            the whole table is purged should sysUpTime wrap.
    
            As this basic row is updated new conceptual rows are created
            (which still share the now updated object values with all
            other instances).  The number of instances which are created
            is determined by the value of sysUpTime at which the basic row
            was last updated.  One instance will exist for each value of
            sysUpTime at the last update time for the row.  A new
            timeMark instance is created for each new sysUpTime value.
            Each new conceptual row will be associated with the timeMark
            instance which was created at the value of sysUpTime with
            which the conceptual row is to be associated.
    
            By definition all conceptual rows were updated at or after
            time zero and so at least one conceptual row (associated with
            timeMark.0) must exist for each underlying (basic) row.
    
            See the appendix for further discussion of this variable.
    
            Consider the following fooTable:
    
            fooTable ...
            INDEX { fooTimeMark, fooIndex }
    
            FooEntry {

               fooIndex     INTEGER,
               fooCounts    Counter
            }
    
            Should there be two basic rows in this table (fooIndex == 1,
            fooIndex == 2) and row 1 was updated most recently at time 6,
            while row 2 was updated most recently at time 8, and both rows
            had been updated on several earlier occasions such that the
            current values were 5 and 9 respectively then the following
            fooCounts instances would exist.
    
            fooCounts.0.1  5

             whether or not this protocol directory entry can be extended
             by the user by creating protocol directory entries which are
             children of this protocol.
    
             An example of an entry that will often allow extensibility is
             `ip.udp'.  The probe may automatically populate some children
             of this node such as `ip.udp.snmp' and `ip.udp.dns'.
             A probe administrator or user may also populate additional
             children via remote SNMP requests that create entries in this
             table.  When a child node is added for a protocol for which the
             probe has no built in support, extending a parent node (for
             which the probe does have built in support),
             that child node is not extendible.  This is termed `limited
             extensibility'.
    
             When a child node is added through this extensibility
             mechanism, the values of protocolDirLocalIndex and
             protocolDirType shall be assigned by the agent.
    
             The other objects in the entry will be assigned by the
             manager who is creating the new entry.
    
             This object also describes whether or not this agent can
             recognize addresses for this protocol, should it be a network
             level protocol.  That is, while a probe may be able to
             recognize packets of a particular network layer protocol and
             count them, it takes additional logic to be able to recognize
             the addresses in this protocol and to populate network layer
             or application layer tables with the addresses in this
             protocol.  If this bit is set, the agent will recognize
             network layer addresses for this protoocl and populate the
             network and application layer host and matrix tables with
             these protocols.
    
             Note that when an entry is created, the agent will supply
             values for the bits that match the capabilities of the agent
             with respect to this protocol.  Note that since row creations
             usually exercise the limited extensibility feature, these
             bits will usually be set to zero."

    -- User History Collection Group (usrHistory)
    --
    -- The usrHistory group combines mechanisms seen in the alarm and
    -- history groups to provide user-specified history collection,
    -- utilizing two additional control tables and one additional data
    -- table. This function has traditionally been done by NMS
    -- applications, via periodic polling.  The usrHistory group allows
    -- this task to be offloaded to an RMON probe.
    --
    -- Data (an ASN.1 INTEGER based object) is collected in the same
    -- manner as any history data table (e.g. etherHistoryTable) except
    -- that the user specifies the MIB instances to be collected. Objects
    -- are collected in bucket-groups, with the intent that all MIB
    -- instances in the same bucket-group are collected as atomically as
    -- possible by the RMON probe.
    --
    -- The usrHistoryControlTable is a one-dimensional read-create table.
    -- Each row configures a collection of user history buckets, much
    -- the same as a historyControlEntry, except that the creation of a
    -- row in this table will cause one or more associated instances in
    -- the usrHistoryObjectTable to be created. The user specifies the
    -- number of bucket elements (rows in the usrHistoryObjectTable)
    -- requested, as well as the number of buckets requested.
    --
    -- The usrHistoryObjectTable is a 2-d read-write table.
    -- Each row configures a single MIB instance to be collected.
    -- All rows with the same major index constitute a bucket-group.
    --
    -- The usrHistoryTable is a 3-d read-only table containing
    -- the data of associated usrHistoryControlEntries. Each
    -- entry represents the value of a single MIB instance
    -- during a specific sampling interval (or the rate of
    -- change during the interval).
    --
    -- A sample value is stored in two objects - an absolute value and
    -- a status object. This allows numbers from -(2G-1) to +4G to be
    -- stored.  The status object also indicates whether a sample is
    -- valid. This allows data collection to continue if periodic
    -- retrieval of a particular instance fails for any reason.
    --
    -- Row Creation Order Relationships
    --
    -- The static nature of the usrHistoryObjectTable creates
    -- some row creation/modification issues. The rows in this
    -- table need to be set before the associated
    -- usrHistoryControlEntry can be activated.
    --
    -- Note that the usrHistoryObject entries associated with a
    -- particular usrHistoryControlEntry are not required to
    -- be active before the control entry is activated. However,
    -- the usrHistory data entries associated with an inactive
    -- usrHistoryObject entry will be inactive (i.e.
    -- usrHistoryValStatus == valueNotAvailable).

            serial data switch.  A ControlString contains embedded
            commands to control how the device will interact with the
            remote device through the serial interface.  Commands are
            represented as two character sequences beginning with
            the `^' character.
    
            The following commands are recognized by the device (note
            that command characters are case sensitive):
    
               ^s  Send string that follows which is terminated by the
                   next command or the end of string.
               ^c  Delay for the number of seconds that follows.  Toss
                   out any data received rather than storing it in a
                   buffer for parsing.
               ^t  Set timeout to the value represented by the decimal
                   digits that follow.  The default timeout is 20
                   seconds. Note that this timeout may be overridden
                   by a smaller serialTimeout configured for the
                   associated serial interface (see serialConfigTable).
               ^w  Wait for the reply string that follows which is
                   terminated by the next command or the end of string.
                   Partial and case insensitive matching is applied, ie.
                   if the reply string (any case combination) is found
                   anywhere in the received string, then the a match is
                   found.  If the current timeout elapses without a match,
                   then the remaining control string is ignored.
               ^!  The ^ character.
               ^d  Delay the number of seconds specified by the decimal
                   digits that follow.
               ^b  Send break for the number of milliseconds specified by
                   the decimal digits that follow.  If no digits follow,
                   break will be enforced for 250 milliseconds by default.
    
            The following ASCII control characters may be inserted into
            the `^s' send string or the `^w' reply string:
    
               ^@    0x00
               ^A    0x01
                ..
               ^M    0x0D
                ..
               ^Z    0x1A
               ^[    0x1B
               ^    0x1C
               ^]    0x1D
               ^^    0x1E
               ^_    0x1F
    
            Binary data may also be inserted into the data stream.  The
            control sequence for each byte of binary data is ^0x##, where
            ## is the hexadecimal representation of the data byte.  Two
            ASCII characters (0-9, a-f, A-F) must follow the `^0x'
            control prefix.  For example, `^0x0D^0x0A' is interpreted as a
            carriage return followed by a line feed."
