TRANSMIT MAC STATISTIC COUNTERS
ifHCOutOctets (Offset 0x0800)
The number of octets transmitted out of the interface, including framing characters.
etherStatsCollisions (Offset 0x0808)
The number of collisions experienced.
outXonSent (Offset 0x080C)
Sent Xon.
outXoffSent (Offset 0x0810)
Sent Xoff.
dot3StatsInternalMacTransmitErrors (Offset 0x0818)
A count of frames for which transmission on a particular interface fails due to an internal MAC sublayer transmit error.
dot3StatsSingleCollisionFrames (Offset 0x081C)
A count of successfully transmitted frames on a particular interface for which transmission is inhibited by exactly one
collision.
dot3StatsMultipleCollisionFrames (Offset 0x0820)
A count of successfully transmitted frames on a particular interface for which transmission is inhibited by more than one
collision.
dot3StatsDeferredTransmissions (Offset 0x0824)
A count of frames for which the first transmission attempt on a particular interface is delayed because the medium is busy.
dot3StatsExcessiveCollisions (Offset 0x082C)
A count of frames for which transmission on a particular interface fails due to excessive collisions.
dot3StatsLateCollisions (Offset 0x0830)
The number of times that a collision is detected on a particular interface later than 512 bit-times into the transmission of a
packet.
ifHCOutUcastPkts (Offset 0x086C)
The number of packets that higher-level protocols requested be transmitted, and that were not addressed to a multicast or
broadcast address at this sublayer, including those that were discarded or not sent.
0x08bc–0x8ff Reserved
