TimeFilter ::= TEXTUAL-CONVENTION
    STATUS current
    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 {
           fooTimeMark  TimeFilter
           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
        fooCounts.0.2  9
        fooCounts.1.1  5

        fooCounts.1.2  9
        fooCounts.2.1  5
        fooCounts.2.2  9
        fooCounts.3.1  5
        fooCounts.3.2  9
        fooCounts.4.1  5
        fooCounts.4.2  9
        fooCounts.5.1  5
        fooCounts.5.2  9
        fooCounts.6.1  5
        fooCounts.6.2  9

    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."

    DESCRIPTION
            "The counter that represents the number of age-outs that

            particular MSAP has been deleted from tables contained in
            lldpRemoteSystemsData and lldpExtensions objects because
            the information timeliness interval has expired.

            This counter is similar to lldpStatsRemTablesAgeouts, except
            that the counter is on a per port basis.  This enables NMS to
            poll tables associated with the lldpRemoteSystemsData objects
            and all LLDP extension objects associated with remote systems
            on the indicated port only.

            This counter should be set to zero during agent initialization
            and its value should not be saved in non-volatile storage.
            When a port's admin status changes from 'disabled' to
            'rxOnly', 'txOnly' or 'txAndRx', the counter associated with
            the same port should reset to 0.  The agent should also flush
            all remote system information associated with the same port.

            This counter should be incremented only once when the
            complete set of information is invalidated (aged out) from
            all related tables on a particular port.  Partial aging
            is not allowed, and thus, should not change the value of
            this counter."

lldpRemTable OBJECT-TYPE
    SYNTAX      SEQUENCE OF LldpRemEntry
    MAX-ACCESS  not-accessible
    STATUS      current
    DESCRIPTION
            "This table contains one or more rows per physical network
            connection known to this agent.  The agent may wish to ensure
            that only one lldpRemEntry is present for each local port,
            or it may choose to maintain multiple lldpRemEntries for
            the same local port.

            The following procedure may be used to retrieve remote
            systems information updates from an LLDP agent:

               1. NMS polls all tables associated with remote systems
                  and keeps a local copy of the information retrieved.
                  NMS polls periodically the values of the following
                  objects:
                     a. lldpStatsRemTablesInserts
                     b. lldpStatsRemTablesDeletes
                     c. lldpStatsRemTablesDrops
                     d. lldpStatsRemTablesAgeouts
                     e. lldpStatsRxPortAgeoutsTotal for all ports.

               2. LLDP agent updates remote systems MIB objects, and
                  sends out notifications to a list of notification
                  destinations.

               3. NMS receives the notifications and compares the new
                  values of objects listed in step 1.  

                  Periodically, NMS should poll the object
                  lldpStatsRemTablesLastChangeTime to find out if anything
                  has changed since the last poll.  if something has
                  changed, NMS will poll the objects listed in step 1 to
                  figure out what kind of changes occurred in the tables.

                  if value of lldpStatsRemTablesInserts has changed,
                  then NMS will walk all tables by employing TimeFilter
                  with the last-polled time value.  This request will
                  return new objects or objects whose values are updated
                  since the last poll.

                  if value of lldpStatsRemTablesAgeouts has changed,
                  then NMS will walk the lldpStatsRxPortAgeoutsTotal and
                  compare the new values with previously recorded ones.
                  For ports whose lldpStatsRxPortAgeoutsTotal value is
                  greater than the recorded value, NMS will have to
                  retrieve objects associated with those ports from
                  table(s) without employing a TimeFilter (which is
                  performed by specifying 0 for the TimeFilter.)
