attempting to transmit a frame on a particular interface. The count represented by an instance of this object is incremented at most once per transmission attempt, even if the carrier sense condition fluctuates during a transmission attempt." REFERENCE "IEEE 802.3 Layer Management" ::= { dot3StatsEntry 11 } -- { dot3StatsEntry 12 } is not assigned dot3StatsFrameTooLongs OBJECT-TYPE SYNTAX Counter32 MAX-ACCESS read-only STATUS current DESCRIPTION "A count of frames received on a particular interface that exceed the maximum permitted frame size. The count represented by an instance of this object is incremented when the frameTooLong status is returned by the MAC service to the 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 } dot3StatsSymbolErrors OBJECT-TYPE SYNTAX Counter32 MAX-ACCESS read-only STATUS current DESCRIPTION "The number of times there was an invalid data symbol when a valid carrier was present on a particular interface. The count represented by an instance of this object is incremented at most once per carrier event, even if multiple symbol errors occur during the carrier event." REFERENCE "IEEE 802.3u-1995 10 & 100 Mb/s Management" ::= { dot3StatsEntry 18 } -- 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 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 dot3TestTdr OBJECT-IDENTITY STATUS current DESCRIPTION "The Time-Domain Reflectometry (TDR) test is specific to ethernet-like interfaces of type 10Base5 and 10Base2. The TDR value may be useful in determining the approximate distance to a cable fault. It is advisable to repeat this test to check for a consistent resulting TDR value, to verify that there is a fault. A TDR test returns as its result the time interval, measured in 10 MHz ticks or 100 nsec units, between the start of TDR test transmission and the subsequent detection of a collision or deassertion of carrier. On successful completion of a TDR test, the result is stored as the value of an appropriate instance of an appropriate vendor specific MIB object, and the OBJECT IDENTIFIER of that instance is stored in the appropriate instance of the appropriate test result code object (thereby indicating where the result has been stored)." ::= { dot3Tests 1 } -- Loopback Test dot3TestLoopBack OBJECT-IDENTITY STATUS current DESCRIPTION "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. If an error occurs during a test, the appropriate test result object will be set to indicate a failure. The two OBJECT IDENTIFIER values dot3ErrorInitError and dot3ErrorLoopbackError may be used to provided more information as values for an appropriate test result code object." ::= { dot3Tests 2 } dot3ErrorInitError OBJECT-IDENTITY STATUS current DESCRIPTION "Couldn't initialize MAC chip for test." ::= { dot3Errors 1 } dot3ErrorLoopbackError OBJECT-IDENTITY STATUS current DESCRIPTION "Expected data not received (or not received correctly) in loopback test." ::= { dot3Errors 2 } -- 802.3 Hardware Chipsets -- The object dot3StatsEtherChipSet is provided to -- identify the MAC hardware used to communicate on an -- interface. The following hardware chipsets are -- registered: dot3ChipSets OBJECT IDENTIFIER ::= { dot3 8 } dot3ChipSetAMD OBJECT IDENTIFIER ::= { dot3ChipSets 1 } dot3ChipSetAMD7990 OBJECT-IDENTITY STATUS current DESCRIPTION "The authoritative identifier for the Advanced Micro Devices Am7990 Local Area Network Controller for Ethernet (LANCE)." ::= { dot3ChipSetAMD 1 } dot3ChipSetAMD79900 OBJECT-IDENTITY STATUS current DESCRIPTION "The authoritative identifier for the Advanced Micro Devices Am79900 chip." ::= { dot3ChipSetAMD 2 } dot3ChipSetAMD79C940 OBJECT-IDENTITY STATUS current DESCRIPTION "The authoritative identifier for the Advanced Micro Devices Am79C940 Media Access Controller for Ethernet (MACE)." ::= { dot3ChipSetAMD 3 } dot3ChipSetAMD79C90 OBJECT-IDENTITY STATUS current DESCRIPTION "The authoritative identifier for the Advanced Micro Devices Am79C90 CMOS Local Area Network Controller for Ethernet (C-LANCE)." ::= { dot3ChipSetAMD 4 } dot3ChipSetAMD79C960 OBJECT-IDENTITY STATUS current DESCRIPTION "The authoritative identifier for the Advanced Micro Devices Am79C960 PCnet-ISA Single Chip Ethernet Controller for ISA."
