Software Release 4.1
inunknownprotos count
This field displays how many inbound packets were discarded because of an unknown or
unsupported protocol.
outoctets count
This field displays how many octets were transmitted out of the interface, including those that
deliver framing information.
outucastpkts count
This field displays how many packets for which the higher-level protocols requested transmission to
a subnetwork-unicast address. The number includes those that were discarded or not sent.
outnucastpkts count
This field displays how many packets for which the higher-level protocols requested transmission to
a non-unicast (subnetwork-broadcast or subnetwork-multicast) address. The number includes
those that were discarded or not sent.
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.
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.
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.
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.
