TxSingleCollisions
A count of successfully transmitted
frames on a particular interface where
the transmission is inhibited by exactly
one collision. A frame that is counted
by an instance of this object is also
counted by the corresponding instance
of either the UnicastPkts,
MulticastPkts, or BroadcastPkts, and is
not counted by the corresponding
instance of the MultipleCollisionFrames
object.
Note: N/A - half-duplex only
Port_Index +
0x4E
RR
0x00000000
TxMultipleCollisions
A count of successfully transmitted
frames on a particular interface for
which transmission is inhibited by more
than one collision. A frame that is
counted by an instance of this object is
also counted by the corresponding
instance of either the UnicastPkts,
MulticastPkts, or BroadcastPkts, and is
not counted by the corresponding
instance of the SingleCollisionFrames
object.
Note: N/A - half-duplex only
Port_Index +
0x4F
RR
0x00000000
TxLateCollisions
The number of times a collision is
detected on a particular interface later
than 512 bit-times into the transmission
of a packet. Such frame are terminated
and discarded.
Note: N/A - half-duplex only
Port_Index +
0x50
RR
0x00000000
ExcessiveCollisionErrors
A count of frames, which collides 16
times and is then discarded by the
MAC. Not effecting xMultipleCollisions
Note: N/A - half-duplex only
Port_Index +
0x51
RR
0x00000000
ExcessiveDeferralErrors
Number of times frame transmission is
postponed more than 2*MaxFrameSize
due to another frame already being
transmitted on the Ethernet network.
This causes the MAC to discard the
frame.
Note: N/A - half-duplex only
Port_Index +
0x52
RR
0x00000000
TxExcessiveLengthDrop
Frame transmissions aborted by the
MAC because the frame is longer than
maximum frame size. These frames
are truncated by the MAC when the
maximum frame size violation is
detected by the MAC.
Port_Index +
0x53
RR
0x00000000
TxUnderrun
Internal TX error which causes the
MAC to end the transmission before
the end of the frame because the MAC
did not get the needed data in time for
transmission. The frames are lost and
a fragment or a CRC error is
transmitted.
Port_Index +
0x54
RR
0x00000000
