         Note that this definition of jabber is different

         (10BASE5) and section 10.3.1.4 (10BASE2).  These
         documents define jabber as the condition where any

         jabber is between 20 ms and 150 ms."

 etherHistoryCollisions OBJECT-TYPE
     SYNTAX     Counter32
     UNITS      "Collisions"
     MAX-ACCESS read-only
     STATUS     current
     DESCRIPTION
         "The best estimate of the total number of collisions
         on this Ethernet segment during this sampling
         interval.

         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 Alarm Group

 -- Implementation of the Alarm group is optional. The Alarm Group
 -- requires the implementation of the Event group.
 -- Consult the MODULE-COMPLIANCE macro for the authoritative
 -- conformance information for this MIB.
 --
 -- The Alarm group periodically takes statistical samples from
 -- variables in the probe and compares them to thresholds that have
 -- been configured.  The alarm table stores configuration
 -- entries that each define a variable, polling period, and
 -- threshold parameters.  If a sample is found to cross the
 -- threshold values, an event is generated.  Only variables that
 -- resolve to an ASN.1 primitive type of INTEGER (INTEGER, Integer32,
 -- Counter32, Counter64, Gauge32, or TimeTicks) may be monitored in
 -- this way.
 --
 -- This function has a hysteresis mechanism to limit the generation
 -- of events.  This mechanism generates one event as a threshold
 -- is crossed in the appropriate direction.  No more events are
 -- generated for that threshold until the opposite threshold is
 -- crossed.
 --
 -- In the case of a sampling a deltaValue, a probe may implement
 -- this mechanism with more precision if it takes a delta sample
 -- twice per period, each time comparing the sum of the latest two
 -- samples to the threshold.  This allows the detection of threshold
 -- crossings that span the sampling boundary.  Note that this does
 -- not require any special configuration of the threshold value.
 -- It is suggested that probes implement this more precise algorithm.

         should be taken in the case of deltaValue

         increase or decrease by more than 2^31 - 1 during

         Because SNMP access control is articulated entirely
         in terms of the contents of MIB views, no access
         control mechanism exists that can restrict the value of
         this object to identify only those objects that exist
         in a particular MIB view.  Because there is thus no
         acceptable means of restricting the read access that
         could be obtained through the alarm mechanism, the
         probe must only grant write access to this object in
         those views that have read access to all objects on
         the probe.

         During a set operation, if the supplied variable name is
         not available in the selected MIB view, a badValue error
         must be returned.  If at any time the variable name of
         an established alarmEntry is no longer available in the
         selected MIB view, the probe must change the status of
         this alarmEntry to invalid(4).
