dot3StatsSQETestErrors {dot3StatsEntry 6}
Counter Read-Only
The number of times an SQE failure ( i.e., heartbeat lost) occurred, since the port
was last enabled. This counter is only incremented when heartbeat is lost, if the
port has been configured to expect heartbeat (see sifExpectSQE). Increments to
this counter correspond to one or more packets experiencing SQE failure. In
other words, a single increment to this counter may indicate that many packet
transmissions experienced SQE failure.
dot3StatsDeferredTransmissions {dot3StatsEntry 7}
Counter Read-Only
The number of frames for which the first transmission attempt was delayed
because the medium was busy. Zero is always returned.
dot3StatsLateCollisions {dot3StatsEntry 8}
Counter Read-Only
The number of times that a late collision was detected. Zero is always returned.
dot3StatsExcessiveCollisions {dot3StatsEntry 9}
Counter Read-Only
The number of times a frame transmission attempt experienced excessive
collisions, since the port was last enabled.
dot3StatsInternalMACTransmitErrors {dot3StatsEntry 10}
Counter Read-Only
The number of times a frame transmission attempt experienced an error other
than dot3StatsSQETestErrors, dot3StatsExcessiveCollisions, or
dot3StatsCarrierSenseErrors, since the port was last enabled.
dot3StatsCarrierSenseErrors {dot3StatsEntry 11}
Counter Read-Only
The number of times that a carrier sense condition was lost during a transmission
attempt, since the port was last enabled.
dot3StatsExcessiveDeferrals {dot3StatsEntry 12}
Counter Read-Only
The number of times that transmission was deferred for an excessive period of
time. Zero is always returned.
