ethernetPortStatsAlignmentErrors
Module: ACMIB
OID (symbolic): ACMIB::ethernetPortStatsAlignmentErrors
OID (numeric): 1.3.6.1.4.1.1751.2.18.10.7.1.3
Node type: OBJECT-TYPE
Type: Integer32
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 obtain are, according to the conventions of IEEE 802.3 Layer Management, counted exclusively according to the error status presented to the LLC.
What is ethernetPortStatsAlignmentErrors?
This OID counts received frames that are not an integral number of octets in length and fail the FCS (Frame Check Sequence) validation, indicating serious MAC layer damage. A network engineer monitors this counter to detect hardware problems, cable faults, or severe electrical noise that corrupts frame boundaries. A value of 25 means 25 malformed frames were received on this port, suggesting a physical layer problem requiring investigation.
