Description

rfc2665_Dot3StatsLate
Collisions

2665

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 a generic collision for purposes of other collision-related

statistics. This counter does not increment when the interface is
operating in full-duplex mode. Discontinuities in the value of this counter

can occur at reinitialization of the management system and at other

times as indicated by the value of ifCounterDiscontinuityTime.

rfc2665_Dot3StatsSQE
TestErrors

2665

The number of times that the SQE TEST ERROR message is generated by
the PLS sublayer for a particular interface. The SQE TEST ERROR is set

in accordance with the rules for verification of the SQE detection

mechanism in the PLS Carrier Sense Function as described in IEEE Std.
802.3, 1998 Edition, section 7.2.4.6. This counter does not increment

on interfaces operating at speeds greater than 10 Mb/s, or on

interfaces operating in full-duplex mode. Discontinuities in the value of
this counter can occur at reinitialization of the management system and

at other times as indicated by the value of ifCounterDiscontinuityTime.

The object type is dot3StatsSQETestErrors.

rfc2665_Dot3StatsSingle
CollisionFrames

2665

The number of successfully transmitted frames on a particular interface
for which 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 ifOutUcastPkts, ifOutMulticastPkts, or
ifOutBroadcastPkts, and is not counted by the corresponding instance

of the dot3StatsMultipleCollisionFrames object. This counter does not

increment when the interface is operating in full-duplex mode.
Discontinuities in the value of this counter can occur at reinitialization of

the management system and at other times as indicated by the value of

ifCounterDiscontinuityTime.

rfc2665_Dot3StatsSymbol
Errors

2665

For an interface operating at 100 Mb/s, the number of times there was
an invalid data symbol when a valid carrier was present.

For an interface operating in half-duplex mode at 1000 Mb/s, the

number of times the receiving media is non-idle (a carrier event) for a
period of time equal to or greater than slotTime, and during which there

was at least one occurrence of an event that caused the PHY to indicate

'Data reception error' or 'carrier extend error' on the GMII.

For an interface operating in full-duplex mode at 1000 Mb/s, the
number of times the receiving media is non-idle (a carrier event) for a

period of time equal to or greater than minFrameSize, and during

which there was at least one occurrence of an event that caused the
PHY to indicate 'Data reception error' on the GMII. The count

represented by an instance of this object is incremented once per

carrier event at most, even if multiple symbol errors occur during the
carrier event. This count does not increment if a collision is present.

Discontinuities in the value of this counter can occur at reinitialization of

the management system and at other times as indicated by the value of
ifCounterDiscontinuityTime.
