dot3StatsCarrierSenseErrors
Module: EtherLike-MIB
OID (symbolic): EtherLike-MIB::dot3StatsCarrierSenseErrors
OID (numeric): 1.3.6.1.2.1.10.7.2.1.11
Node type: OBJECT-TYPE
Type: Counter32
Access: read-only
Description: The number of times that the carrier sense condition was lost or never asserted when attempting to transmit a frame on a particular interface.
The count represented by an instance of this object is incremented at most once per transmission attempt, even if the carrier sense condition fluctuates during a transmission attempt.
This counter does not increment when the interface is operating in full-duplex mode.
Discontinuities in the value of this counter can occur at re-initialization of the management system, and at other times as indicated by the value of ifCounterDiscontinuityTime.
What is dot3StatsCarrierSenseErrors?
This counter records how many times, on this interface, the carrier sense signal was lost or never detected while the device was trying to transmit a frame. Admins use it to spot physical-layer transmit problems, since it increments at most once per transmission attempt and only on half-duplex links, making it a useful indicator of a failing transceiver or bad cabling. For example, a steadily increasing count on a half-duplex 10/100 port could indicate a loose or damaged Ethernet cable preventing reliable carrier detection.
