 Received Broadcast
Packets
The number of packets, delivered by this sub-layer to a higher (sub-) layer,
addressed to a broadcast address at this sub-layer.
 Transmit Multicast
Packets
The total number of packets that higher-level protocols requested is transmitted
and is addressed to a multicast address at this sub-layer, including those that
were discarded or not sent.
 Transmit Broadcast
Packets
The total number of packets that higher-level protocols requested is transmitted,
and addressed to a broadcast address at this sub-layer, including those that were
discarded or not sent.

Object Description
 Alignment Errors
The number of alignment errors (missynchronized data packets).
 FCS Errors
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.
 Single Collision
Frames
The number of successfully transmitted frames for which transmission is inhibited
by exactly one collision.
 Multiple Collision
Frames
A count of successfully transmitted frames 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 was busy.
 Late Collision
The number of times that a collision is detected later than 512 bit-times into the
transmission of a packet.
 Excessive Collision
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
