rptrMonitorPortLateEvents
Module: RFC1516-MIB
OID (symbolic): RFC1516-MIB::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?
Count of collisions detected on this port later than the normal collision window (past roughly 480-565 bit times), each also counted as an ordinary collision. Late collisions specifically point to a cabling distance or topology problem — a segment that's too long or has too many repeaters between the colliding stations — rather than ordinary contention.
