LAN Interface Card Statistics
Multiple Collision Frames A count of successfully transmitted frames on
a particular interface for which transmission is
inhibited by more than one collision.
Deferred Transmissions A count of frames for which the first
transmission attempt on a particular interface is
delayed because the medium is busy. The count
represented by an instance of this object does not
include frames involved in collisions.
Late Collisions The number of times that a collision is detected on a
particular interface later than 512 bit-times into the
transmission of a packet.
Excessive Collisions A couple of frames for which transmission on a
particular interface fails due to excessive collisions.
Internal MAC Transmit Errors A count of frames for which
transmission on a particular interface fails due to an
internal MAC sublayer transmit error.
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.
Frames Too Long Account of frames received on a particular interface
that exceed the maximum permitted frame size.
Internal MAC Receive Errors A count of frames for which reception on a
particular interface fails due to an internal MAC
sublayer receive error
