Ethernet Support Guide for HP-UX 11i v3

Single Collision Frames A count of successfully transmitted frames on a particular
interface for which transmission is inhibited by exactly one
collision.
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 or packets dropped.
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 A count 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.
