            "Bug fixes, clarifications and minor changes based on
    implementation experience, published as RFC1757 [18].
    
    Two changes were made to object definitions:
    
    1) A new status bit has been defined for the
    captureBufferPacketStatus object, indicating that the
    packet order within the capture buffer may not be identical to
    the packet order as received off the wire.  This bit may only
    be used for packets transmitted by the probe.  Older NMS
    applications can safely ignore this status bit, which might be
    used by newer agents.
    
    2) The packetMatch trap has been removed.  This trap was never
    actually 'approved' and was not added to this document along
    with the risingAlarm and fallingAlarm traps. The packetMatch
    trap could not be throttled, which could cause disruption of
    normal network traffic under some circumstances. An NMS should
    configure a risingAlarm threshold on the appropriate
    channelMatches instance if a trap is desired for a packetMatch
    event. Note that logging of packetMatch events is still
    supported--only trap generation for such events has been
    removed.
    
    In addition, several clarifications to individual object
    definitions have been added to assist agent and NMS
    implementors:
    
    - global definition of 'good packets' and 'bad packets'
    
    - more detailed text governing conceptual row creation and
      modification
    
    - instructions for probes relating to interface changes and
      disruptions
    
    - clarification of some ethernet counter definitions
    
    - recommended formula for calculating network utilization
    
    - clarification of channel and captureBuffer behavior for some
      unusual conditions
    
    - examples of proper instance naming for each table";

            "The status of a table entry.
    
    Setting this object to the value invalid(4) has the
    effect of invalidating the corresponding entry.
    That is, it effectively disassociates the mapping
    identified with said entry.
    It is an implementation-specific matter as to whether
    the agent removes an invalidated entry from the table.
    Accordingly, management stations must be prepared to
    receive tabular information from agents that corresponds
    to entries currently not in use.  Proper
    interpretation of such entries requires examination
    of the relevant EntryStatus object.
    
    An existing instance of this object cannot be set to
    createRequest(2).  This object may only be set to
    createRequest(2) when this instance is created.  When
    this object is created, the agent may wish to create
    supplemental object instances with default values
    to complete a conceptual row in this table.  Because the
    creation of these default objects is entirely at the option
    of the agent, the manager must not assume that any will be
    created, but may make use of any that are created.
    Immediately after completing the create operation, the agent
    must set this object to underCreation(3).
    
    When in the underCreation(3) state, an entry is allowed to
    exist in a possibly incomplete, possibly inconsistent state,
    usually to allow it to be modified in multiple PDUs.  When in
    this state, an entry is not fully active.
    Entries shall exist in the underCreation(3) state until
    the management station is finished configuring the entry
    and sets this object to valid(1) or aborts, setting this
    object to invalid(4).  If the agent determines that an
    entry has been in the underCreation(3) state for an
    abnormally long time, it may decide that the management
    station has crashed.  If the agent makes this decision,
    it may set this object to invalid(4) to reclaim the
    entry.  A prudent agent will understand that the
    management station may need to wait for human input
    and will allow for that possibility in its
    determination of this abnormally long period.
    
    An entry in the valid(1) state is fully configured and
    consistent and fully represents the configuration or
    operation such a row is intended to represent.  For
    example, it could be a statistical function that is
    configured and active, or a filter that is available
    in the list of filters processed by the packet capture
    process.
    
    A manager is restricted to changing the state of an entry in
    the following ways:
    
         To:       valid  createRequest  underCreation  invalid
    From:
    valid             OK             NO             OK       OK
    createRequest    N/A            N/A            N/A      N/A
    underCreation     OK             NO             OK       OK
    invalid           NO             NO             NO       OK
    nonExistent       NO             OK             NO       OK
    
    In the table above, it is not applicable to move the state
    from the createRequest state to any other state because the
    manager will never find the variable in that state.  The
    nonExistent state is not a value of the enumeration, rather
    it means that the entryStatus variable does not exist at all.
    
    An agent may allow an entryStatus variable to change state in
    additional ways, so long as the semantics of the states are
    followed.  This allowance is made to ease the implementation of
    the agent and is made despite the fact that managers should
    never exercise these additional state transitions.";

    The value returned will depend on the location of the
    RMON probe. Section 8.2.1.3 (10BASE-5) and section
    10.3.1.3 (10BASE-2) of IEEE standard 802.3 states that a
    station must detect a collision, in the receive mode, if
    three or more stations are transmitting simultaneously.  A
    repeater port must detect a collision when two or more
    stations are transmitting simultaneously.  Thus a probe
    placed on a repeater port could record more collisions
    than a probe connected to a station on the same segment
    would.
    
    Probe location plays a much smaller role when considering
    10BASE-T.  14.2.1.4 (10BASE-T) of IEEE standard 802.3
    defines a collision as the simultaneous presence of signals
    on the DO and RD circuits (transmitting and receiving
    at the same time).  A 10BASE-T station can only detect
    collisions when it is transmitting.  Thus probes placed on
    a station and a repeater, should report the same number of
    collisions.
    
    Note also that an RMON probe inside a repeater should
    ideally report collisions between the repeater and one or
    more other hosts (transmit collisions as defined by IEEE
    802.3k) plus receiver collisions observed on any coax
    segments to which the repeater is connected.";

    The value returned will depend on the location of the
    RMON probe. Section 8.2.1.3 (10BASE-5) and section
    10.3.1.3 (10BASE-2) of IEEE standard 802.3 states that a
    station must detect a collision, in the receive mode, if
    three or more stations are transmitting simultaneously.  A
    repeater port must detect a collision when two or more
    stations are transmitting simultaneously.  Thus a probe
    placed on a repeater port could record more collisions
    than a probe connected to a station on the same segment
    would.
    
    Probe location plays a much smaller role when considering
    10BASE-T.  14.2.1.4 (10BASE-T) of IEEE standard 802.3
    defines a collision as the simultaneous presence of signals
    on the DO and RD circuits (transmitting and receiving
    at the same time).  A 10BASE-T station can only detect
    collisions when it is transmitting.  Thus probes placed on
    a station and a repeater, should report the same number of
    collisions.
    
    Note also that an RMON probe inside a repeater should
    ideally report collisions between the repeater and one or
    more other hosts (transmit collisions as defined by IEEE
    802.3k) plus receiver collisions observed on any coax
    segments to which the repeater is connected.";

    initially takes the value zero.  Then, for each
    error, E, that has been discovered in this packet,
    2 raised to a value representing E is added to the sum.
    The errors and the bits that represent them are dependent

    Ethernet interface are as follows:
    
        bit #    Error
    	0    Packet is longer than 1518 octets
    	1    Packet is shorter than 64 octets
    	2    Packet experienced a CRC or Alignment error
