Description
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.
The count represented by an instance of this object is
incremented when the alignmentError status is returned by
the MAC service to the LLC (or other MAC user). Received
frames for which multiple error conditions obtain are,
according to the conventions of IEEE 802.3 Layer
Management, counted exclusively according to the error
status presented to the LLC.
This counter does not increment for 8-bit wide group
encoding schemes.
A count of frames received on a particular interface that
exceed the maximum permitted frame size.
The count represented by an instance of this object is
incremented when the frameTooLong status is returned by
the MAC service to the LLC (or other MAC user). Received
frames for which multiple error conditions obtain are,
according to the conventions of IEEE 802.3 Layer
Management, counted exclusively according to the error
status presented to the LLC.
Number of pause frames transmitted.
The number of times that a collision is detected on a
particular interface later than one slotTime into the
transmission of a packet.
A (late) collision included in a count represented by an
instance of this object is also considered as a (generic)
collision for purposes of other collision-related statistics.
This counter does not increment when the interface is
operating in full-duplex mode.
A count of frames for which transmission on a particular
interface fails due to excessive collisions.
This counter does not increment when the interface is
operating in full-duplex mode.
