REGAD[7:0]
(Low/High)
Carrier sense dropout errors, i.e.
number of times that carrier sense is
not asserted or deasserted during
packet transmission, without a collision.
This counter is only incremented once
per packet, regardless of the number of
dropout errors in the packet.
Equivalent to
TX
"dot3StatsCarrierSenseErrors"
32
Use Ctr. #44
Bytes, exclusive of preamble,
RX
in good packets only.
0b11011010
0b11011011
Packets with receive FIFO overflow
error.
RX
Equivalent to "etherStatsDropEvents"
Use Ctr. #1
TX Multicast packets, good only.
Equivalent to
TX
"etherStatsMulticastPkts_TX"
Use Ctr. #21
TX Broadcast packets, good only.
Equivalent to
TX
"etherStatsBroadcastPkts_TX"
32
Use Ctr. #20
Packets with excessive deferral,
i.e. packets waiting for transmission
longer than two max packet times.
Since controller is Full Duplex only,
TX
this counter is undefined.
0b11011100
0b11011101
Multicast packets, good only.
RX
Equivalent to "etherStatsMulticastPkts"
Use Ctr. #5
Broadcast packets, good only.
RX
Equivalent to "etherStatsBroadcastPkts" 32
Use Ctr. #4
Packets of legal-length whose actual
length is different from length/type field
0b11011110
RX
value.
32
0b11011111
Packets with length/type
RX
field value > Max_Packet_Length.
0b11100000
0b11100001
Packets of length > Max_Packet_Length
with no other errors.
RX
Equivalent to "etherStatsOversizePkts" 32
