ethPortLateEvents
Module: MODULES-MIB
OID (symbolic): MODULES-MIB::ethPortLateEvents
OID (numeric): 1.3.6.1.4.1.81.12.3.1.1.30
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 approximate minimum time for rollover of this counter is 81 hours. This object is a Repeater MIB counter.
What is ethPortLateEvents?
Counts late collisions on this port, i.e. collisions detected later in the frame transmission than the normal collision window allows, which the repeater also double-counts in ethPortCollisions; a nonzero late-event count is a classic sign of a cable run that's too long or has a duplex mismatch, and rolls over in roughly 81 hours.
Examples
Walk all instances (SNMPv2c):
snmpwalk -v2c -c public <target> 1.3.6.1.4.1.81.12.3.1.1.30 snmpwalk -v2c -c public <target> MODULES-MIB::ethPortLateEvents
Get a specific instance (index 1):
snmpget -v2c -c public <target> 1.3.6.1.4.1.81.12.3.1.1.30.1 snmpget -v2c -c public <target> MODULES-MIB::ethPortLateEvents.1
