              -- management station has crashed.  If the agent makes
              -- this decision, it may set this object to invalid(4)

              -- understand that the management station may need to
              -- wait for human input and will allow for that

                  source can be any ethernet interface on this device.
                  In order to identify a particular interface, this
                  object shall identify the instance of the ifIndex
                  object, defined in RFC 1213 and RFC 1573 [4,6], for
                  the desired interface.  For example, if an entry
                  were to receive data from interface #1, this object
                  would be set to ifIndex.1.

                  The statistics in this group reflect all packets
                  on the local network segment attached to the
                  identified interface.

                  An agent may or may not be able to tell if
                  fundamental changes to the media of the interface
                  have occurred and necessitate an invalidation of
                  this entry.  For example, a hot-pluggable ethernet

                  token-ring card.  In such a case, if the agent has

                  it invalidate this entry.

                  This object may not be modified if the associated

                  "The best estimate of the total number of collisions
                  on this Ethernet segment.

                  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."

          -- Once samples are taken, their data is stored in an entry

          -- sample, and is associated with the historyControlEntry that
          -- caused the sample to be taken.  Each counter in the
          -- etherHistoryEntry counts the same event as its

                  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
