802.3 Std).
The approximate minimum time for rollover of this counter is 80 hours."

Alignment Errors
"This counter is incremented by one for each frame received on this port
with the FCSError and FramingError signals asserted and CollisionEvent
signal deasserted and whose OctetCount is greater than or equal to
minFrameSize and less than or equal to maxFrameSize (Ref: IEEE 802.3
Std, 4.4.2.1). If rptrMonitorPortAlignmentErrors is incremented then the
rptrMonitorPortFCSErrors Counter shall not be incremented for the same
frame.
The approximate minimum time for rollover of this counter is 80 hours."

Frame Too Longs
"This counter is incremented by one for each frame received on this port
whose OctetCount is greater than maxFrameSize (Ref: 4.4.2.1, IEEE 802.3
Std). If rptrMonitorPortFrameTooLongs is incremented then neither the
rptrMonitorPortAlignmentErrors nor the rptrMonitorPortFCSErrors counter
shall be incremented for the frame.
The approximate minimum time for rollover of this counter is 61 days."

Short Events
"This counter is incremented by one for each CarrierEvent on this port with
ActivityDuration less than ShortEventMaxTime. ShortEventMaxTime is
greater than 74 bit times and less than 82 bit times. ShortEventMaxTime has
tolerances included to provide for circuit losses between a conformance test
point at the AUI and the measurement point within the state machine.
Note: shortEvents may indicate externally generated noise hits which will
cause the repeater to transmit Runts to its other ports, or propagate a
collision (which may be late) back to the transmitting DTE and damaged
frames to the rest of the network.
