Description: The total number of packets received that had a length (excluding framing bits, but including FCS octets) of between 64 and 1518 octets, inclusive, but but had either a bad Frame Check Sequence (FCS) with an integral number of octets (FCS Error) or a bad FCS with a non-integral number of octets (Alignment Error).
What is rEtherStatsCRCAlignErrors?
This counter tracks packets between 64 and 1518 octets that had either a bad Frame Check Sequence with an integral octet count or a bad FCS with a non-integral count (alignment error). A rising count typically points to a bad cable, connector, or duplex mismatch on that segment.
