rptrMonitorPortLateEvents
Module: SNMP-REPEATER-MIB
OID (symbolic): SNMP-REPEATER-MIB::rptrMonitorPortLateEvents
OID (numeric): 1.3.6.1.2.1.22.2.3.1.1.11
Node type: OBJECT-TYPE
Type: Counter32
Access: read-only
Description: For a clause 9 repeater port, 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. For a clause 27 repeater port, this counter is incremented by one on entering the Collision Count Increment state
of the partition state diagram (fig 27-8) while the ActivityDuration is greater than the LateEvent- Threshold. 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.
A discontinuity may occur in the value when the value of object rptrMonitorPortLastChange changes.
The approximate minimum time for rollover of this counter is 81 hours in a 10Mb/s repeater.
What is rptrMonitorPortLateEvents?
Counts collisions on this port detected later than expected in the frame (a 'late collision'), which typically points to a cable run that's too long or a duplex mismatch on the attached device.
