Packets not successfully transmitted
after more than 15 collisions (i.e.:
attempt value=16).
Packets with transmit FIFO underflow
error. Equivalent to “ifOutDiscards”
Carrier sense dropout errors, i.e. num-
ber of times that carrier sense is not
asserted or deasserted during packet
transmission, without a collision.
Bytes, exclusive of preamble, in good
packets only.
Packets with receive FIFO overflow
error. Equivalent to
“etherStatsDropEvents”
Multicast packets, good only. Equivalent

Broadcast packets, good only. Equiva-
lent to “etherStatsBroadcastPkts_TX”
Packets with excessive deferral, i.e.
packets waiting for transmission longer
than two max packet times.
Multicast packets, good only. Equivalent
to “etherStatsMulticastPkts”
Broadcast packets, good only. Equiva-
lent to “etherStatsBroadcastPkts”
Packets of legal-length whose actual
length is different from length/type field

Max_Packet_Length.
Packets of length > Max_Packet_Length
with no other errors.
Equivalent to “etherStatsOversizePkts”
CRS asserted and one or more symbol
errors(RXER pin asserted) received
from a PHY, exclusive of collision.
