ifOutBroadcastPkts
TX
Broadcast packets, good and bad.
0b11000000
0b11000001
33
ifOutNUcastPkts
Broadcast and multicast packets,
good and bad.
Equivalent to "ifOutMulticastPkts +
Use Ctr.

ifOutBroadcastPkts"
32
#32 and 33
34
ifOutDiscards
Packets with transmit FIFO underflow
0b11000010
TX
error.
32
0b11000011
35
ifOutErrors
All Packets, bad only,
TX
exclusive of legal-length errors.
0b11000100
32
0b11000101
Ethernet-Like Group MIB (RFC 1643)
dot3StatsAlignmentErrors
Packets with alignment error only.
There are no alignment errors in
8B10B Gigabit Ethernet,
RX
so this counter is undefined.
0b11000110
0b11000111
36
dot3StatsFCSErrors
Packets with CRC error only.
Equivalent to
RX
"etherStatsCRCAlignErrors"
32
Use Ctr. #6
Packets successfully transmitted after
one and only one collision (ie: attempt
value = 2).
Since controller is Full Duplex only,
0b11001010
38
dot3StatsSingleCollisionFrames
TX
this counter is undefined.
32
0b11001011
Packets successfully transmitted after
more than one collision (ie: 2<attempt
value<16).
Since controller is Full Duplex only,
0b11001100
39
dot3StatsMultipleCollisionFrames TX
this counter is undefined.
32
0b11001101
40
dot3StatsSQETestErrors
Number of times SQE was asserted.
There is no SQE for Gigabit Ethernet,
0b11001110
RX
so this counter is undefined.
32
0b11001111
Packets deferred, i.e. packets whose
transmission was delayed due to busy
medium, on first attempt only.
Since controller is Full Duplex only,
0b11010000
41
dot3StatsDeferredTransmissions
TX
this counter is undefined.
32
0b11010001
