RFC1284-MIB by vendor RFC

RFC1284-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.

-- the Ethernet-like Statistics group

-- Implementation of this group is mandatory

-- Due to implementation restrictions (e.g. in the
-- instrumentation provided by a chipset, or a device
-- driver), some of the counters in this group may be
-- difficult or impossible to implement.
-- In such cases, an implementator should apply reasonable
-- best effort to detect as many occurrences as possible.
-- In any case, the value of a counter will be the number
-- actually detected, which will always be less or equal
-- to the number of actual occurrences.  In the extreme
-- case of a total inability to detect occurrences, the
-- counter will always be zero.

-- Vendors are strongly encouraged to document in user guides and
-- other appropriate documentation the conditions under which the
-- values of the counters in this group may represent an
-- underestimate of the true count.

            the maximum allowed LLC data size.

            The count represented by an instance of this
            object is not incremented in implementations that
            observe Ethernet encapsulation conventions (by

    DESCRIPTION
            "A count of frames for which reception on a
            particular interface fails due to an internal MAC
            sublayer receive error. A frame is only counted by
            an instance of this object if it is not counted by
            the corresponding instance of either the
            dot3StatsFrameTooLongs object, the

            dot3StatsInRangeLengthErrors object, or the

            dot3StatsOutOfRangeLengthFields object.

            The precise meaning of the count represented by an
            instance of this object is implementation-
            specific.  In particular, an instance of this
            object may represent a count of receive errors on
            a particular interface that are not otherwise
            counted."

--  802.3 Tests

-- The ifExtnsTestTable defined in [11] provides a common means
-- for a manager to test any interface corresponding to a value
-- of ifIndex.

-- At this time, one well known test (testFullDuplexLoopBack) is
-- defined in [11].  For ethernet-like interfaces, this test
-- configures the MAC chip and executes an internal loopback
-- test of memory and the MAC chip logic.  This loopback test can

-- only be executed if the interface is offline.  Once the test
-- has completed, the MAC chip should be reinitialized for network
-- operation, but it should remain offline.

-- If an error occurs during a test, the object ifExtnsTestResult
-- (defined in [11]) will be set to failed(7).  The following two
-- OBJECT IDENTIFIERs may be used to provided more information as
-- values for the object ifExtnsTestCode in [11]:

dot3Errors             OBJECT IDENTIFIER ::= { dot3 7 }

                          -- couldn't initialize MAC chip for test
dot3ErrorInitError     OBJECT IDENTIFIER ::= { dot3Errors 1 }

                          -- expected data not received (or not
                          -- received correctly) in loopback test
dot3ErrorLoopbackError OBJECT IDENTIFIER ::= { dot3Errors 2 }


--  TDR Test

-- Another test, specific to ethernet-like interfaces,
-- is Time-domain Reflectometry (TDR) which is defined
-- as follows:

dot3Tests   OBJECT IDENTIFIER ::= { dot3 6 }
dot3TestTdr OBJECT IDENTIFIER ::= { dot3Tests 1 }

-- A TDR test returns as its result the time interval between the
-- most recent TDR test transmission and the subsequent detection
-- of a collision.  This interval is based on a 10 MHz clock and
-- should be normalized if the time base is other than 10 MHz.
-- On successful completion of a TDR test, the result is stored
-- as the value of the appropriate instance of the MIB object
-- dot3TestTdrValue, and the OBJECT IDENTIFIER of that instance
-- is stored in the corresponding instance of ifExtnsTestResult
-- (thereby indicating where the result has been stored).


--  802.3 Hardware Chipsets

-- The object ifExtnsChipSet is provided in [11] to identify the
-- MAC hardware used to communcate on an interface.  The following
-- hardware chipsets are provided for 802.3:

dot3ChipSets          OBJECT IDENTIFIER ::= { dot3 8 }

-- assignment is required in other documentation, e.g., assignment
-- within that part of the registration tree delegated to
-- individual enterprises (see [3]).
