rptrMonitorPortLateEvents
Module: LANART-AGENT
OID (symbolic): LANART-AGENT::rptrMonitorPortLateEvents
OID (numeric): 1.3.6.1.2.1.22.2.3.1.1.11
Node type: OBJECT-TYPE
Type: Counter
Access: read-only
Description: This counter is incremented by one for each CarrierEvent on this port in which the CollIn(X) variable transitions to the value SQE (Ref: 9.6.6.2, IEEE 802.3 Std) while the ActivityDuration is greater than the LateEventThreshold. Such a CarrierEvent is counted twice, as both a collision and as a lateEvent.
The LateEventThreshold is greater than 480 bit times and less than 565 bit times. LateEventThreshold has tolerances included to permit an implementation to build a single threshold to serve as both the LateEventThreshold and ValidPacketMinTime threshold.
The approximate minimum time for rollover of this counter is 81 hours.
What is rptrMonitorPortLateEvents?
Counts late collisions on this port — a collision detected too far into the frame to be a normal early collision — which almost always points to a cabling problem, a duplex mismatch, or a segment that's too long; rolls over roughly every 81 hours.
