is the number of packets received/transmitted over the interface.
Packets In/Out
is the number of bytes received/transmitted over the interface.
Bytes In/Out
is the number of packets received/transmitted via a multicast
Multi-Cast In/Out
address over the interface.
is the number of packets received/transmitted via a broadcast
Broadcast In/Out
address over the interface.
is the number of incoming/outgoing frames that were dropped.
Frm Dropped In/Out
is the number of incoming Q-packets that were dropped.
Q Dropped In
is the number of transmitted frames that did not return due to a
Dropped Timeout
timeout or reception of another frame.
is the number of errors received over the interface.
Errors In
is the number of frames with FCS (frame check sequence) errors
Alignment Errors
due to non-integral lengths.
is the number of frames that were transmitted after one collision
Xmt w/1 Coll
(with a frame transmitted from another node).
is the number of frames that were not accepted due to DMA (direct
Overrun Errors
memory access) overrun errors.
is the number of frames that were transmitted after multiple colli-
Xmt w/mul Coll
sions.
is the number of frames that were held up due to traffic from other
Xmt/Deferral
directions, then transmitted later.
is the number of frames that were transmitted containing a CD
Xmt CD Heartbeat
(collision detection) signal.
is the number of frames that were not transmitted due to collisions.
Not Xmt (Coll)
is the number of frames that experienced a loss of the CS (carrier
Frm w/lost CS
sense) signal at the receiving node.
is the number of transmitted frames that were involved in colli-
Late Collisions
sions while outside the flow control window.
is the number of frames that were not accepted due to DMA (direct
Underruns
memory access) underrun errors.
is the number of frames received that have failed the Frame Check
FCS Violations
Sequence (FCS) cyclic redundancy check (CRC).
is the number of frames received with duplicate addresses.
Copy Errors
is the number of five half-bit time transitions. The counter is incre-
Trans Absences
mented every time transitions are not detected between SDEL and
EDEL in a repeated frame.
