CRC Align Errors The total number of frames received that had a
length (excluding framing bits but including Frame
Check Sequence (FCS) octets) of from 64 through
1518 octets. The error indicates either a bad FCS
with an integral number of octets (an FCS error) or a
bad FCS with a non-integral number of octets (an
Alignment error).

received. Large symbol errors indicate a bad device,
cable, or hardware.
