Field Description
Alignment Errors A count of frames received on a particular interface that are not
an integral number of octets in length and do not pass the FCS
check.
Alignment Errors can result from MAC layer packet formation
problems, cabling problems that cause corrupted or lost data,
and packets that pass through more than two cascaded
multiport transceivers.
FCS Errors A count of frames received on a particular interface that are not
an integral number of octets in length and do not pass the FCS
check.
FCS or Alignment Errors indicate bit errors during a
transmission or reception.
Single Collisions A count of successfully transmitted frames on a particular
interface for which transmission is inhibited by exactly one
collision.
Multiple Collisions A count of successfully transmitted frames on a particular
interface for which transmission is inhibited by more than one
collision.
SQE Test Errors A count of of times that the Signal Quality Error (SQE) TEST
ERROR message is generated. The SQE Test is used to test for
the collision present circuit between a transceiver and a network
interface card (NIC).
Deferred Transmissions A count of frames for which the first transmission attempt on a
particular interface is delayed because the medium is busy.
Late Collisions Number of times that a collision is detected later than 512 bit-
times into the transmission of a packet
Excessive Collisions Number of frames for which transmission fails due to excessive
collisions
MAC Transmit Errors A count of frames for which transmission on a particular
interface fails due to an internal MAC sublayer transmit error.
A faulty network transmitter can cause Internal MAC Transmit
errors. Check the device to insure that it is functioning correctly.
Carrier Sense Errors The number of times that the carrier sense condition was lost or
never asserted when attempting to transmit a frame on a
particular interface.
