SNMP-REPEATER-MIB file content

The SNMP protocol is used to for conveying information and commands between agents and managing entities. SNMP uses the User Datagram Protocol (UDP) as the transport protocol for passing data between managers and agents. The reasons for using UDP for SNMP are, firstly it has low overheads in comparison to TCP, which uses a 3-way hand shake for connection. Secondly, in congested networks, SNMP over TCP is a bad idea because TCP in order to maintain reliability will flood the network with retransmissions.

Management information (MIB) is represented as a collection of managed objects. These objects together form a virtual information base called MIB. An agent may implement many MIBs, but all agents must implement a particular MIB called MIB-II [16]. This standard defines variables for things such as interface statistics (interface speeds, MTU, octets sent, octets received, etc.) as well as various other things pertaining to the system itself (system location, system contact, etc.). The main goal of MIB-II is to provide general TCP/IP management information.

    DESCRIPTION
        "Management information for 802.3 repeaters.

        The following references are used throughout
        this MIB module:

        [IEEE 802.3 Std]
            refers to IEEE 802.3/ISO 8802-3 Information
            processing systems - Local area networks -
            Part 3: Carrier sense multiple access with

            collision detection (CSMA/CD) access method
            and physical layer specifications (1993).

        [IEEE 802.3 Mgt]
            refers to IEEE 802.3u-1995, '10 Mb/s &
            100 Mb/s Management, Section 30,'
            Supplement to ANSI/IEEE 802.3.

        The following terms are used throughout this
        MIB module.  For complete formal definitions,
        the IEEE 802.3 standards should be consulted
        wherever possible:

        System - A managed entity compliant with this
        MIB, and incorporating at least one managed
        802.3 repeater.

        Chassis - An enclosure for one managed repeater,
        part of a managed repeater, or several managed
        repeaters.  It typically contains an integral
        power supply and a variable number of available
        module slots.

        Repeater-unit - The portion of the repeater set
        that is inboard of the physical media interfaces.
        The physical media interfaces (MAUs, AUIs) may be
        physically separated from the repeater-unit, or
        they may be integrated into the same physical
        package.

        Trivial repeater-unit - An isolated port that can
        gather statistics.

        Group - A recommended, but optional, entity
        defined by the IEEE 802.3 management standard,
        in order to support a modular numbering scheme.
        The classical example allows an implementor to
        represent field-replaceable units as groups of
        ports, with the port numbering matching the
        modular hardware implementation.

        System interconnect segment - An internal
        segment allowing interconnection of ports
        belonging to different physical entities
        into the same logical manageable repeater.
        Examples of implementation might be
        backplane busses in modular hubs, or
        chaining cables in stacks of hubs.

        Stack - A scalable system that may include
        managed repeaters, in which modularity is
        achieved by interconnecting a number of
        different chassis.

        Module - A building block in a modular
        chassis.  It typically maps into one 'slot';
        however, the range of configurations may be
        very large, with several modules entering
        one slot, or one module covering several
        slots.

    DESCRIPTION

            The rptrGroupCapacity is the number of groups
            that can be contained within the repeater.  Within
            each managed repeater, the groups are uniquely
            numbered in the range from 1 to rptrGroupCapacity.

            Some groups may not be present in the repeater, in
            which case the actual number of groups present
            will be less than rptrGroupCapacity.  The number
            of groups present will never be greater than
            rptrGroupCapacity.

            Note:  In practice, this will generally be the
            number of field-replaceable units (i.e., modules,
            cards, or boards) that can fit in the physical
            repeater enclosure, and the group numbers will

    DESCRIPTION
            "********* THIS OBJECT IS DEPRECATED **********

            Setting this object to reset(2) causes a
            transition to the START state of Fig 9-2 in
            section 9 [IEEE 802.3 Std] for a 10Mb/s repeater,
            and the START state of Fig 27-2 in section 27
            of that standard for a 100Mb/s repeater.

            Setting this object to noReset(1) has no effect.
            The agent will always return the value noReset(1)
            when this object is read.

            After receiving a request to set this variable to
            reset(2), the agent is allowed to delay the reset
            for a short period.  For example, the implementor
            may choose to delay the reset long enough to allow
            the SNMP response to be transmitted.  In any
            event, the SNMP response must be transmitted.

            This action does not reset the management counters
            defined in this document nor does it affect the
            portAdminStatus parameters.  Included in this
            action is the execution of a disruptive Self-Test
            with the following characteristics:  a) The nature
            of the tests is not specified.  b) The test resets
            the repeater but without affecting management
            information about the repeater.  c) The test does
            not inject packets onto any segment.  d) Packets
            received during the test may or may not be
            transferred.  e) The test does not interfere with
            management functions.

            After performing this self-test, the agent will
            update the repeater health information (including
            rptrOperStatus and rptrHealthText), and send a
            rptrHealth trap."

            disruptive self-test that has the following
            characteristics:  a) The nature of the tests is
            not specified.  b) The test does not change the
            state of the repeater or management information
            about the repeater.  c) The test does not inject
            packets onto any segment.  d) The test does not
            prevent the relay of any packets.  e) The test
            does not interfere with management functions.

            After performing this test, the agent will update
            the repeater health information (including
            rptrOperStatus and rptrHealthText) and send a

            Note that this definition allows returning an

            received during the test may or may not be
            transferred.  e) The test does not interfere with
            management functions.

            After performing this self-test, the agent will

            Notes:

            ShortEvents may indicate externally
            generated noise hits which will cause the repeater
            to transmit Runts to its other ports, or propagate
            a collision (which may be late) back to the
            transmitting DTE and damaged frames to the rest of
            the network.

            Implementors may wish to consider selecting the
            ShortEventMaxTime towards the lower end of the
            allowed tolerance range to accommodate bit losses
            suffered through physical channel devices not
            budgeted for within this standard.

            The significance of this attribute is different

            "The total number of errors which have occurred on

            values of other error counters (for the same

                rptrMonitorPortDataRateMismatches, and
                rptrMonitorPortSymbolErrors.

            This counter is redundant in the sense that it is
            the summation of information already available
            through other objects.  However, it is included
            specifically because the regular retrieval of this
            object as a means of tracking the health of a port
            provides a considerable optimization of network
            management traffic over the otherwise necessary

            retrieval of the summed counters.

            Note that rptrMonitorPortRunts is not included
            in this total; this is because runts usually
            indicate collision fragments, a normal network
            event.

            "This table contains one entry per repeater in the
            system.  It defines objects which allow a network
            management application to instruct an agent to watch
            for a given MAC address and report which port it
            was seen on.  Only one address search can be in
            progress on each repeater at any one time.  Before
            starting an address search, a management application
            should obtain 'ownership' of the entry in
            rptrAddrSearchTable for the repeater that is to
            perform the search.  This is accomplished with the
            rptrAddrSearchLock and rptrAddrSearchStatus as
            follows:

            try_again:
                get(rptrAddrSearchLock, rptrAddrSearchStatus)
                while (rptrAddrSearchStatus != notInUse)
                {
                    /* Loop waiting for objects to be available*/
                    short delay
                    get(rptrAddrSearchLock, rptrAddrSearchStatus)
                }

                /* Try to claim map objects */
                lock_value = rptrAddrSearchLock
                if ( set(rptrAddrSearchLock = lock_value,
                         rptrAddrSearchStatus = inUse,
                         rptrAddrSearchOwner = 'my-IP-address)
                      == FAILURE)
                    /* Another manager got the lock */
                    goto try_again

                /* I have the lock */
                set (rptrAddrSearchAddress = <search target>)

                wait for rptrAddrSearchState to change from none

                if (rptrAddrSearchState == single)
                    get (rptrAddrSearchGroup, rptrAddrSearchPort)


                /* release the lock, making sure not to overwrite
                   anyone else's lock */
                set (rptrAddrSearchLock = lock_value+1,
                     rptrAddrSearchStatus = notInUse,
                     rptrAddrSearchOwner = '')

            A management station first retrieves the values of
            the appropriate instances of the rptrAddrSearchLock
            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."

-- The Repeater Top "N" Port Group


-- The Repeater Top N Port group is used to prepare reports that
-- describe a list of ports ordered by one of the statistics in the
-- Repeater Monitor Port Table.  The statistic chosen by the
-- management station is sampled over a management
-- station-specified time interval, making the report rate based.
-- The management station also specifies the number of ports that
-- are reported.
--
-- The rptrTopNPortControlTable is used to initiate the generation
-- of a report.  The management station may select the parameters
-- of such a report, such as which repeater, which statistic, how
-- many ports, and the start & stop times of the sampling.  When
-- the report is prepared, entries are created in the
-- rptrTopNPortTable associated with the relevent
-- rptrTopNControlEntry.  These entries are static for
-- each report after it has been prepared.

-- Note that counter discontinuities may appear in some
-- implementations if ports' assignment to repeaters changes
-- during the collection of data for a Top "N" report.
-- A management application could read the corresponding
-- rptrMonitorPortLastChange timestamp in order to check
-- whether a discontinuity occurred.
