Description
The number of alignment errors (missynchronized data packets).
A count of frames received on a particular interface that are an integral number of
octets in length but do not pass the FCS check. This count does not include
frames received with frame-too-long or frame-too-short error.
The number of successfully transmitted frames for which transmission is inhibited
by exactly one collision.
A count of successfully transmitted frames for which transmission is inhibited by
more than one collision.
A count of frames for which the first transmission attempt on a particular interface
is delayed because the medium was busy.
The number of times that a collision is detected later than 512 bit-times into the
transmission of a packet.
A count of frames for which transmission on a particular interface fails due to
excessive collisions. This counter does not increase when the interface is
operating in full-duplex mode.
A count of frames received on a particular interface that exceeds the maximum
permitted frame size.
The number of received and transmitted symbol errors
The number of received control unknown opcodes
The number of received pause frames
The number of transmitted pause frames
