dot3HCStatsAlignmentErrors
Module: EtherLike-MIB
OID (symbolic): EtherLike-MIB::dot3HCStatsAlignmentErrors
OID (numeric): 1.3.6.1.2.1.10.7.11.1.1
Node type: OBJECT-TYPE
Type: Counter64
Access: read-only
Description:
A count of frames received on a particular interface that are not an integral number of octets in length and do not pass the FCS check.
The count represented by an instance of this object is incremented when the alignmentError status is returned by the MAC service to the LLC (or other MAC user). Received frames for which multiple error conditions pertain are, according to the conventions of IEEE 802.3 Layer Management, counted exclusively according to the error status presented to the LLC.
This counter does not increment for group encoding schemes greater than 4 bits per group.
This counter is a 64 bit version of dot3StatsAlignmentErrors. It should be used on interfaces operating at 10 Gb/s or faster.
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 dot3HCStatsAlignmentErrors?
This OID counts Ethernet frames that arrived on an interface corrupted—either with an odd number of bytes or with a failed integrity check (FCS error). A rising count indicates cable problems, interference, or faulty hardware. A network operator monitoring this counter would investigate if it increases suddenly, as it suggests physical layer issues that may degrade performance.
