1
etherStatsDropEvents
RX
Packets with receive FIFO overflow
error.
32
0b10000000
0b10000001
2
etherStatsOctets
RX
Bytes, exclusive of preamble, in good
or bad packets. Bytes in packets
with bad SFD are excluded.1
32
0b10000010
0b10000011
3
etherStatsPkts
RX
All packets, good or bad.1
32
0b10000100
0b10000101
4
etherStatsBroadcastPkts
RX
Broadcast packets, good only.1
32
0b10000110
0b10000111
5
etherStatsMulticastPkts
RX
Multicast packets, good only.1
32
0b10001000
0b10001001
6
etherStatsCRCAlignErrors
RX
Packets of legal-length with CRC error
or alignment error.
There are no alignment errors in 8B10B
Gigabit Ethernet, so this counter will
only count CRC errors for legal length
packets.
32
0b10001010
0b10001011
7
etherStatsUndersizePkts
RX
Packets of length < 64 bytes with no
other errors.
32
0b10001100
0b10001101
8
etherStatsOversizePkts
RX
Packets of length > Max_Packet_Length
with no other errors.
32
0b10001110
0b10001111
9
etherStatsFragments
RX
Packets of length < 64 bytes with CRC
error or alignment error.
There are no alignment errors in 8B10B
Gigabit Ethernet, so this counter will
only count CRC errors with length < 64.
32
0b10010000
0b10010001
10
etherStatsJabber
RX
Packets of length > Max_Packet_Length
with CRC error or alignment error.
There is no jabber function in Gigabit
Ethernet, so this counter is undefined.
32
0b10010010
0b10010011
