fethPortLateEvents
Module: MODULES-MIB
OID (symbolic): MODULES-MIB::fethPortLateEvents
OID (numeric): 1.3.6.1.4.1.81.12.6.1.1.1.21
Node type: OBJECT-TYPE
Type: Counter
Access: read-only
Description: 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 collision and a late event.
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. REFERENCE Reference IEEE Draft Std 802.3u/D4 Rptr Mgt, 30.4.3.1.12, aLateEvents. Reference IETF 100Base-T Repeater MIB, rptr100MonitorPortLateEvents.
What is fethPortLateEvents?
Counts late collisions on this port, i.e. collisions the repeater detects later in a frame than the normal collision window permits; as on the 10Mbps side, a late collision is double-counted as both a regular collision and a late event, and its presence is a classic symptom of excessive cable length or a duplex mismatch.
