        respectively, and the number of seconds in the interval is
        Interval.  These values are used to calculate the Utilization
        as follows:

                         Pkts * (9.6 + 6.4) + (Octets * .8)
         Utilization = -------------------------------------
                                 Interval * 10,000

        The result of this equation is the value Utilization which
        is the percent utilization of the ethernet segment on a
        scale of 0 to 100 percent."

etherStatsCollisions OBJECT-TYPE

    UNITS      "Collisions"
    MAX-ACCESS read-only
    STATUS     current
    DESCRIPTION
        "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."

-- The History Control Group

-- Implementation of the History Control group is optional.
-- Consult the MODULE-COMPLIANCE macro for the authoritative
-- conformance information for this MIB.
--
-- The history control group controls the periodic statistical
-- sampling of data from various types of networks.  The
-- historyControlTable stores configuration entries that each
-- define an interface, polling period, and other parameters.
-- Once samples are taken, their data is stored in an entry
-- in a media-specific table.  Each such entry defines one
-- 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 similarly-named
-- counterpart in the etherStatsEntry, except that each value here
-- is a cumulative sum during a sampling period.
--
-- If the probe keeps track of the time of day, it should start
-- the first sample of the history at a time such that
-- when the next hour of the day begins, a sample is
-- started at that instant.  This tends to make more
-- user-friendly reports, and enables comparison of reports
-- from different probes that have relatively accurate time
-- of day.
--
-- The probe is encouraged to add two history control entries
-- per monitored interface upon initialization that describe a short
-- term and a long term polling period.  Suggested parameters are 30
-- seconds for the short term polling period and 30 minutes for
-- the long term period.
