Attribute Meaning
outdiscards Count This field displays how many outbound packets were discarded
without errors that would have prevented their transmission.
(Some of these packets may have been discarded to increase
buffer space.)
outerrrors Count This field displays how many outbound packets contained errors
that prevented their transmission.
RxBabErr This field displays how many receiver babble errors occurred.
TxHbErr This field displays how many transmit heartbeat errors have
occured.
EthBusErr This field displays how many Ethernet bus errors occurred on the
Ethernet controller.
CRCError This field displays how many CRC errors occurred on the
Ethernet controller.
RcvFifoNoBuf This field displays the number of times no FIFO buffer space was
able to be allocated
RxOverrun This field displays how many receiver overrun errors occurred on
the Ethernet controller.
Late Collision
This field displays how many late collisions occurred on the
Ethernet controller. A normal collision occurs during the first 512
bits of the frame transmission. A collision that occurs after the
first 512 bits is considered a late collision.
IMPORTANT!
A late collision is a serious network problem
because the frame being transmitted is
discarded. A late collision is most commonly
caused by a mismatch between duplex
configurations at the ends of a link segment.
RetransLimitExp This field displays how many times the retransmit limit has
expired.
TxUnderrun This field displays how many transmission-underrun errors
occurred on the Ethernet controller.
CarSenseLost This field displays how many carrier sense lost errors occurred on
the Ethernet controller.
No Carrier This field displays how many no carrier errors occurred on the
Ethernet controller.
