Field Description
IfName
An index name that uniquely identifies an
interface to an ethernet-like medium.
Alignment Errors
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. For
interfaces operating at 10 Gb/s, this counter
can roll over in less than 5 minutes if it is
incrementing at its maximum rate. Since that
amount of time could be less than a
management station's poll cycle time, in order
to avoid a loss of information, a management
station is advised to poll the
dot3HCStatsAlignmentErrors object for 10
Gb/s or faster interfaces. Discontinuities in the
value of this counter can occur at re-
