               valid frames that have been received on this port,

               rptrMonitorPortReadableOctets object.

               This two-counter mechanism is provided for those
               network management protocols that do not support
               64-bit counters (e.g. SNMP V1) and are used to
               manage a repeater type of 100Mb/s.

               Conformance clauses for this MIB are defined such
               that implementation of this object is not required
               in a system which does not support 100Mb/s.
               However, systems with mixed 10 and 100Mb/s ports
               may implement this object across all ports,
               including 10Mb/s.  If this object is implemented,
               it must be according to the definition in the first
               paragraph of this description; that is, the value
               of this object MUST be a valid count.

               and rptrAddrSearchStatus objects, periodically
               repeating the retrieval if necessary, until the value
               of rptrAddrSearchStatus is 'notInUse'.  The
               management station then tries to set the same
               instance of the rptrAddrSearchLock object to the
               value it just retrieved, the same instance of the
               rptrAddrSearchStatus object to 'inUse', and the
               corresponding instance of rptrAddrSearchOwner to a
               value indicating itself.  If the set operation
               succeeds, then the management station has obtained
               ownership of the rptrAddrSearchEntry, and the value
               of rptrAddrSearchLock is incremented by the agent (as
               per the semantics of TestAndIncr).  Failure of the
               set operation indicates that some other manager has
               obtained ownership of the rptrAddrSearchEntry.

               Once ownership is obtained, the management station
               can proceed with the search operation.  Note that the
               agent will reset rptrAddrSearchStatus to 'notInUse'
               if it has been in the 'inUse' state for an abnormally
               long period of time, to prevent a misbehaving manager
               from permanently locking the entry.  It is suggested
               that this timeout period be between one and five
               minutes.

               When the management station has completed its search
               operation, it should free the entry by setting
               the instance of the rptrAddrSearchLock object to the
               previous value + 1, the instance of the
               rptrAddrSearchStatus to 'notInUse', and the instance
               of rptrAddrSearchOwner to a zero length string.  This
               is done to prevent overwriting another station's
               lock."

       DESCRIPTION
               "In a system containing multiple managed
               repeaters, the rptrInfoResetEvent notification
               conveys information related to the operational
               status of a repeater. This notification is sent
               on completion of a repeater reset action.  A
               repeater reset action is defined as a transition
               to the START state of Fig 9-2 in section 9 of
               [IEEE 802.3 Std], when triggered by a management
               command (e.g., an SNMP Set on the rptrInfoReset
               object).

               The agent must throttle the generation of
               consecutive rptrInfoResetEvent notifications for
               a single repeater so that there is at least
               a five-second gap between notifications of
               this type.  When notifications are throttled,
               they are dropped, not queued for sending at
               a future time.  (Note that 'generating' a
               notification means sending to all configured
               recipients.)

               The rptrInfoResetEvent is not sent when the
               agent restarts and sends an SNMP coldStart or
               warmStart trap.  However, it is recommended that
               a repeater agent send the rptrInfoOperStatus
               object as an optional object with its coldStart
               and warmStart trap PDUs."
       REFERENCE
               "[IEEE 802.3 Mgt], 30.4.1.3.2, nRepeaterReset
               notification."
