LLC (or other MAC user). Received frames for which multiple error conditions obtain are, according to the conventions of IEEE 802.3 Layer Management, counted exclusively according to the error status presented to the LLC." REFERENCE "IEEE 802.3 Layer Management" ::= { dot3StatsEntry 13 } -- { dot3StatsEntry 14 } is not assigned -- { dot3StatsEntry 15 } is not assigned dot3StatsInternalMacReceiveErrors OBJECT-TYPE SYNTAX Counter32 MAX-ACCESS read-only STATUS current 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 dot3StatsAlignmentErrors object, or the dot3StatsFCSErrors 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." REFERENCE "IEEE 802.3 Layer Management" ::= { dot3StatsEntry 16 } dot3StatsEtherChipSet OBJECT-TYPE SYNTAX OBJECT IDENTIFIER MAX-ACCESS read-only STATUS current DESCRIPTION "This object contains an OBJECT IDENTIFIER which identifies the chipset used to realize the interface. Ethernet-like interfaces are typically built out of several different chips. The MIB implementor is presented with a decision of which chip to identify via this object. The implementor should identify the chip which is usually called the Medium Access Control chip. If no such chip is easily identifiable, the implementor should identify the chip which actually gathers the transmit and receive statistics and error indications. This would allow a manager station to correlate the statistics and the chip generating them, giving it the ability to take into account any known anomalies in the chip." ::= { dot3StatsEntry 17 } -- the Ethernet-like Collision Statistics group -- Implementation of this group is optional; it is appropriate -- for all systems which have the necessary metering dot3CollTable OBJECT-TYPE SYNTAX SEQUENCE OF Dot3CollEntry MAX-ACCESS not-accessible STATUS current DESCRIPTION "A collection of collision histograms for a particular set of interfaces." ::= { dot3 5 } dot3CollEntry OBJECT-TYPE SYNTAX Dot3CollEntry MAX-ACCESS not-accessible STATUS current DESCRIPTION "A cell in the histogram of per-frame collisions for a particular interface. An instance of this object represents the frequency of individual MAC frames for which the transmission (successful or otherwise) on a particular interface is accompanied by a particular number of media collisions." INDEX { ifIndex, dot3CollCount } ::= { dot3CollTable 1 } Dot3CollEntry ::= SEQUENCE { dot3CollCount INTEGER, dot3CollFrequencies Counter32 } -- { dot3CollEntry 1 } is no longer in use dot3CollCount OBJECT-TYPE SYNTAX INTEGER (1..16) -- MAX-ACCESS not-accessible MAX-ACCESS read-only STATUS current DESCRIPTION "The number of per-frame media collisions for which a particular collision histogram cell represents the frequency on a particular interface." ::= { dot3CollEntry 2 } dot3CollFrequencies OBJECT-TYPE SYNTAX Counter32 MAX-ACCESS read-only STATUS current DESCRIPTION "A count of individual MAC frames for which the transmission (successful or otherwise) on a particular interface occurs after the frame has experienced exactly the number of collisions in the associated dot3CollCount object. For example, a frame which is transmitted on interface 77 after experiencing exactly 4 collisions would be indicated by incrementing only dot3CollFrequencies.77.4. No other instance of dot3CollFrequencies would be incremented in this example." ::= { dot3CollEntry 3 } -- 802.3 Tests dot3Tests OBJECT IDENTIFIER ::= { dot3 6 } dot3Errors OBJECT IDENTIFIER ::= { dot3 7 } -- TDR Test -- The Time-Domain Reflectometry (TDR) test is specific -- to ethernet-like interfaces with the exception of -- 10BaseT and 10BaseF.

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 instanceis stored in the corresponding instance -- of ifExtnsTestCode (thereby indicating where the -- result has been stored). -- Loopback Test -- Another test is the full-duplex loopback test. -- This test configures the MAC chip and executes -- an internal loopback test of memory, data paths, -- 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. dot3TestLoopBack OBJECT IDENTIFIER ::= { dot3Tests 2 } -- If an error occurs during a test, the object -- ifTestResult (defined in RFC1573) will be set -- to failed(7).
